MUNICIPAL MAINTENANCE

QUALITATIVE RESULTS

Municipality: City of Concord Permit Year: (2006/2007)

Introduction:

City of Concord pollution prevention plans addresses storage, use, and disposal of hazardous materials in a safe manner to avoid the possibility of stormwater pollution. The plans identify potential sources of hazardous materials that could affect the quality of stormwater discharged from Concord sites. The plans also describe the best management practices to reduce or prevent pollutants in the stormwater discharge.

Staff used a Stormwater Pollution Prevention Plan for the municipal corporation yard for contain pollutants on-site and adequately clean up and dispose of these pollutants in the safest manner. The plan identified potential sources of hazardous materials that could affect the quality of storm water discharged from the site. The plan also describes the best management practices to reduce or prevent pollutants in the storm water discharge.

Staff was notified on October 4 that Concord’s Corporation Yard Stormwater Pollution Prevention Plan (SWPPP) was selected as a statewide model by the League of California Cities. Concord’s 50-page SWPPP is a plan for containing pollutants on-site and adequately cleaning up and disposing of these pollutants in the safest manner. The SWPPP is a guide for the containment and clean up of spills, as well as direction for daily "good housekeeping" activities to reduce the amounts of pollutants that leave the Corporation Yard through stormwater or other runoff. The measures contained in the SWPPP are those required to conform to federal and state laws.

Good housekeeping avoided spills by keeping work areas clean, neat and tidy. The City was pro-active in preventative maintenance to anticipate potential pollution problems. Corporation Yard personnel were instructed to maintain clean, neat, and tidy work areas and to immediately clean up spilled materials so as not to contribute to or cause a larger spill. Particular attention was devoted to minimizing spills and to a rapid clean up and containment of those spills that do occur. Minor spills typically involve small quantities (less than one quart) of oil, gasoline, paint, etc., which could be controlled by the first responder at the discovery of the spill.

City crews used dry methods, swept and used absorbent cleaning agents to clean work areas instead of hosing them down. Crews swept outside areas regularly and put the debris in the garbage, instead of sweeping or hosing it into the street. Crews kept dumpster lids closed and the areas around them clean. Crews did not put liquid waste in dumpsters or hose them out. Crews promptly called Concord Disposal Services to replace any dumpsters if they were found to leak.

Storm drain inlets in Concord were stenciled with the words "No dumping. Drains to Bay." Our annual catch basin inspections continued to show a relatively clean system. All 5,600 storm drain inlets were inspected and cleaned at least once in addition to 2 miles of v-ditches and open channels, and 6 miles of roadside ditches, and watercourses including inlets, culverts, and trash racks. Some of the parts of the stormwater drainage system that were inspected in our annual program were catch basins, storm drain inlets, flow control structures, creeks, lakes, and ponds. In Fiscal

Staff maintains an active Integrated Pest Management (IPM) plan for long-term prevention or suppression of pest problems with minimal impact on human health, non-target organisms, and the environment. For pest problems on City property, staff followed Standard Operating Procedures. Pesticides were used only after monitoring indicated that they are needed according to established guidelines and treatments were made with the goal of removing only target organisms. Pest control materials were selected and applied in a manner that minimized risks to human health to beneficial and non-target organisms and to the environment. Over the past ten years, Concord has not increased the amount of chemicals used while the area covered had increased with the addition of new parks, street medians and open space. Whenever possible, instead of spraying, staff used beneficial insects and insecticidal soap. The State of California certified all of Concords pesticide application supervisors. Each was required to take continuing education classes four times a year and in-house training on related information and safety training. The City of Concord presented a case study of street sweeping alternatives at the May 3, 2007 County-wide Municipal Maintenance Workshop. More details are at Attachment 209 - Municipal Maintenance Workshop 5-3-07 Attachment 283 has a copy of the workshop registration form and Attachment 284 has a copy of the agenda.

Spills were reported immediately to ensure that the environment is protected. Crews were trained to respond quickly to all spills particularly those that could do environmental damage if response is delayed. Attachment 258 is a certificate of training from the BASMAA Recognized Surface Cleaner program. Large spills would have been reported immediately to Contra Costa County Hazardous Materials. Smaller spills were handled by Public Works-Maintenance Services using the Spill Response Flow Chart showing actions to be taken and notifications to be made in the case of a spill. This flow chart was distributed to maintenance supervisory personnel and used in crew training. Each section of Public Works has a copy of the spill response phone tree which readily identifies the agencies and individuals to be contacted in case of a spill.

During FY 2006/07, our street sweepers swept 197 curb miles of arterial streets and industrial areas monthly, 671 curb miles of residential streets twice monthly, and 7 curb miles of downtown streets weekly. This was a total of 875 curb miles swept on a regular schedule of at least monthly. During the year crews swept 2,760 miles of arterial streets, 13,191 miles of residential streets, and 364 miles of downtown streets. This was a total of 16,315 miles swept with mechanical street sweepers. Street sweeping materials were analyzed for eight specific pollutants. Here are the quantities of each removed by street sweeping in FY 2006-07. Attachment 313 has Photographs.

Sweeping Materials Analysis

Staff again reviewed Concord’s street sweeping practices to develop an optimum mix of methods. By fine-tuning the type of equipment used and the timing, we were able to improve the sweeping service. Using a mix of vacuum sweeping, towed sweeping, blowing out, public education, and enforcement, we were able to maximize effectiveness by applying the proper methods to each street at the optimum time. Downtown streets were scheduled for sweeping very early in the morning to avoid sweeping around parked vehicles. Residential neighborhoods were swept in the morning or at midday when people had taken their cars out to run errands or go to work. We found that several streets are full of parked cars at all times of the day or night. Blowing out with a backpack blower was scheduled for these streets heavily impacted with parked cars. The blowing out method allowed us to remove litter without moving the cars.

Recycling was an important program in Concord. Concord was a member of the Contra Costa Recycling Market Development Zone. Concord Disposal provided every single-family household weekly pickup for residential curbside recycling. Every single-family residence was provided a blue and a white recycling bin. The blue bin was for paper products: newspapers, colored paper, advertising inserts, white paper, computer paper, magazines, envelopes without windows, phone books, and cardboard. Cardboard could also be tied, no larger than 24 inches, and placed alongside the bin. The white bin was for: all #1 and #2 container plastic (HDPE and PET); glass bottles and jars—clear or any color glass; aluminum cans; California redemption plastic soft drink bottles—PET #1, non-carbonated beverage containers; tin and steel-plated cans.

Concord was named a Tree City U.S.A. by the National Arbor Day Foundation to honor Concord’s commitment to its community forest. It is the twenty–sixth year Concord has received this national recognition. Concord was also the recipient of a Tree City U.S.A. Growth Award for the ninth year for demonstrating progress in its community forestry program.

Implementation & Evaluation:

Performance Standard 001

Goal: Sweep curbed streets on at least a monthly average unless an alternative schedule is approved as described in MUNI-2. In calculating this average, the number of curb miles swept in a fiscal year divided by the number of curb miles within an agency will equal twelve or greater.

POC: Jeff Roubal, Senior Administration Analyst [email protected], (925) 671-3394

Date Started: 07/01/2006 Date Complete: 07/01/2007 Status: Complete

During FY 2006/07, our street sweepers swept 197 curb miles of arterial streets and industrial areas monthly, 671 curb miles of residential streets twice monthly, and 7 curb miles of downtown streets weekly. This was a total of 875 curb miles swept on a regular schedule of at least monthly. During the year crews swept 2,760 miles of arterial streets, 13,191 miles of residential streets, and 364 miles of downtown streets. This was a total of 16,315 miles.


Goal: If sweeping streets less than on a monthly average, the rationale for the alternative standard must be described in a written action plan. The rationale should demonstrate the alternative schedule is equivalent in terms of protecting water quality as the annual average sweeping. The action plan will be submitted to the Regional Board as part of the Annual Report. The alternative standard will not be effective until approved by the Regional Board’s Executive Officer, and approval will be presumed unless it is rejected in writing within 90 days of its submittal.


Date Started: 07/01/2006 Date Complete: 07/01/2007 Status: Not Applicable

All streets in Concord are swept at least once a month.


Goal: For agencies that do not sweep every street at least once a month, the street sweeping that is conducted to achieve the monthly average described in MUNI-1 above should be prioritized to sweep the streets that have been found to typically be the dirtiest and to conduct sweeping prior to the rainy season.

The City of Concord sweeps all streets a minimum of once a month.

Performance Standard 004Goal: Identify and target areas for more frequent sweeping throughout the year or just prior to the rainy season.



In February 2002, the Concord City Council authorized a consultant study of street sweeping cycles and practices recommend alternative methods to deliver a more effective Street Sweeping Program in the City. The recommendations of this study were implemented and were described in detail in Concord’s FY 2005-06 Annual Report.

The City has avoided sweeping streets on the same day as trash collection, whenever possible. When it is not possible to sweep on a different day, the trash cans, recycling bins, and bags of green waste get in the way of the sweeper. Sweeper drivers end up “slalom driving” around the obstacles so much that a lot of the curb does not get swept.

Public Works staff was notified in November that Concord Disposal would be changing their trash collection routes for over 70% of their Concord customers. Concord Disposal’s new schedule would have conflicted with 17 of our 30 twice-monthly residential street sweeping routes. To avoid this, staff worked with Concord Disposal to delay implementation of their new trash collection routes for two months. Public Works has completely revised the street sweeping schedule to avoid sweeping on the same day as trash collection. The last time our sweeping schedule was amended was in FY 2003/04 when we changed from bi-weekly to twice-monthly street sweeping for residential routes.

The new schedule went into effect simultaneously with Concord Disposal's new trash collection routes on January 22, 2007. City staff also publicized the changes through district partnerships, public events, neighborhood meetings, community access television, and the Concord Transcript.

Crews worked in another partnership between the Parks Division and the Streets Division to clean all the median island turn pockets along Clayton Road. These pockets tend to accumulate leaves each Fall. Along Clayton Road, pine needles are a particular problem because of the trees in our median island landscaping. Backpack blowers were not working because the wind gusts from passing cars and trucks blew the leaves right back. What was needed was some way to pick up the needles but turn pockets are

MUNI - 5


inaccessible to our large vacuum sweeping trucks. By using both backpack blowers, vacuum sweeping trucks in tandem with mobile traffic control, we were able to clean the turn pockets with a minimum of fuss and inconvenience to the motoring public. This significant cleanup was done once in the Fall and once in the Summer to help keep Concord’s streets looking their very best.


Goal: Check that street sweeping equipment is in proper adjustment.



Sweepers are checked and adjusted as necessary daily. There is an extensive discussion of sweeper equipment maintenance in Concord’s 2005-06 Annual Report.


Goal: When using broom sweepers, the operator will check that the proper weights on main and gutter brooms are used.



Gutter brooms are checked daily and adjusted as needed. There is an extensive discussion of sweeper equipment maintenance in Concord’s 2005-06 Annual Report.


Goal: Discourage allowing residents to “opt out” of street sweeping program.



Residents are not allowed to "opt out" of the City of Concord street sweeping program..


Goal: When purchasing new sweepers, review all alternative equipment and new technologies to maximize pollutant removal.

MUNI - 6






City of Concord staff review all alternative equipment and new technologies to maximize pollutant removal when purchasing new sweepers.


Goal: Provide operators with adequate resources to conveniently report trees interfering with street sweeping.



City of Concord sweeper operators have three ways available to report overgrown trees that hamper street sweeping.

1. While on duty, all sweeper operators carry cellular telephones. These telephones are used to communicate with the City corporation yard, the dispatcher, other city crews, supervisors, and the Clean Water Program Manager. Any operator who sees an overgrown tree that obstructs the street sweeping route is instructed to call the dispatcher. The dispatcher collects all the necessary information then contacts the Neighborhood Preservation Division for trees on private property or the Parks Division for trees on public property.

2. Each driver maintains a daily log of routes swept, yards of debris collected, sweeper truck number, etc. The log page has a section to note comments and problems like overgrown trees. These logs are turned in to the supervisor every two weeks -- on payday. The supervisor contacts the Neighborhood Preservation Division for trees on private property or the Parks Division for trees on public property. A sample log page can be found at Attachment MN-09 to Concord’s FY 2005-06 Annual Report.

3. Every Tuesday morning, there is a meeting of all the sweeper operators. Topics at this meeting include safety, work schedules, upcoming special events, vacations, vehicle availability, weather, and route problems like tree obstructions. Anything reported at the meeting is given to the supervisor who then contacts the Neighborhood Preservation Division for trees on private property or the Parks Division for trees on public property.


Goal: Track and report curbed miles swept in the Annual Report.


MUNI - 7





From the daily operator's logs, staff compiles monthly reports of miles of street swept. Attachments 224, 225, and 226 contain a compilation of all the biweekly sweeping reports for Fiscal Year 2006-07. These statistics are entered into the City of Concord Performance Based Budgeting system. Performance Budget provides an objective basis for decision making. The budget is organized by department, programs, objective and tasks. During the budget development process, line-item accounts are used to budget each task. The performance budget directly relates the labor, material, and other costs in the budget to the results that are produced. This connection provides the means for measuring both the efficiency and effectiveness of resource utilization. Resource allocation decisions in performance budgeting are based on specific service level objectives. Attachment 231 shows a page from Concord’s Performance Based Budgeting system describing the street sweeping task.


Goal: Track volume or weight of material removed in the Annual Report.



Volume of material removed by street sweeping was tracked from the daily operator’s logs and truck weigh tickets. Attachments 224, 225, 226, and 227 show a compilation of this data. There is a sample of an operator’s log at Attachment 249.


Goal: Identify and target areas for additional efforts to remove vehicles, as appropriate.



The City of Concord “Clean Streets Team” was composed of residents who distributed information cards about the street sweeping schedule on windshields of cars parked on residential streets in their sweeping zones. A roster of team members is at Attachment 355. Two or three times a year, volunteers went out the day before scheduled sweeping and placed information cards on the windshields of vehicles parked on the street, on basketball backboards and on other objects that would prevent a clean sweep of the street.

To reach the maximum number of residents, all the handout materials distributed by Concord’s “Clean Streets Team” are printed in distinctive colors with English instructions on one side and Spanish instructions on the other. A sample of the English and Spanish instructions is included at Attachment 215.

MUNI - 8



Attachments 263 and 264 are examples of letters sent to residents and businesses who fail to move their vehicles on street sweeping day.


Goal: Specify in all new or re-bid contracts that in case of equipment failure, back up equipment must be available to ensure the route is completed and all information necessary for record keeping will be provided.



The City of Concord accomplishes all street sweeping with in-house resources. Concord has four street sweepers -- one for each of the three daily routes and one backup sweeper as maintenance spare. Concord has three full-time sweeper operators and several trained personnel who fill in during vacations or illness.


Goal: Maintain a consistent sweeping schedule to the maximum extent practicable (MEP). A copy of the street sweeping schedule shall be submitted with the Annual Report.



The sweeping schedule is published annually and mailed to every residential, business, and other address in Concord. The schedule puts all Concord streets into zones and lists the specific street sweeping dates for each zone for the next twelve months. The schedule is printed with easy to read, three-color graphics on 17" by 11" paper (folded to 8.5" by 11" finished size)

Over 57,000 copies of this schedule were mailed in English and 6,500 copies in Spanish language versions to facilitate widest dissemination of the information. Additional copies of the schedule were distributed to City offices and public libraries where the public would find them easily. A copy of the English and Spanish versions of the 2007 street sweeping schedule is at Attachments 216 and 217. A copy of the schedule by dates for each zone is at Attachment 228.


MUNI - 9



Goal: Take appropriate measures to keep curbed areas clear during street sweeping.

in Business Districts, near large apartment complexes, etc.; posting street sweeping signs on streets where appropriate; and, distributing newsletters and other public education materials notifying residents and businesses of street sweeping schedules.



The City of Concord “Clean Streets Team” is described above in PS 13.

The sweeping schedule is also posted on Concord’s community billboard calendar on Comcast Channel 25, Astound channel 26, and on the City of Concord’s internet web site. Attachment 274 shows a special banner for Concord’s homepage used this year. Attachment MN-37 to Concord’s 2005-06 Annual Report contains a sample street sweeping page from the City of Concord internet site. Residents can access sweeping information seven days a week, 24 hours a day at www.cityofconcord.org Neighborhood and homeowner associations publish the street sweeping days in their newsletters.


Goal: Schedule street sweeping activities when parked cars have minimal impact.

representatives designed a sign in three languages: English, Spanish, and pictures. This sign encourages residents to move their cars on street sweeping day. The City of Concord installed the signs in 24 locations. Attachment 230 shows a map were the signs were installed.

Residential streets were swept during the day when residents are available to move their parked cars. Downtown streets are swept early in the morning before businesses open and customers arrive. Arterial, commercial and industrial streets were swept in the early hours before the workday and the morning commute begins. This is done to ensure that streets are as free of obstructions as possible. Arterial streets are swept when traffic volume is lowest. Sweepers moving at 3-5 MPH would pose a significant hazard on high volume streets. Slow moving sweepers would also impede the flow of traffic by causing traffic jams and accidents. High traffic volumes are shown in Attachment 234.

In 2002, the City of Concord commissioned a consultant study of street sweeping cycles and practices to find alternative methods to deliver a more effective street sweeping program in the City. The recommendations of this study are described in detail in Concord’s FY 2005-06 Annual Report.


Goal: Investigate and develop, if necessary, alternative methods of handling leaf fall and develop an appropriate leaf removal program, such as:

Operate street sweeping equipment in tandem, Utilize a leaf removal machine just prior to street sweeping, Utilize a front end loader with a dump truck just prior to sweeping, and/or Encourage residents to collect and compost leaves or coordinate with a local

composting program. If composting is infeasible, agencies may schedule removal of bagged leaves.



Residents were encouraged to bag their leaves for weekly pick-up. Pick-up of green waste, including leaves, was integrated free as part of the municipal trash collection service. Residents were allowed to set out 5 bags a week, no more than 50 pounds per bag. A brand-new flyer was created last year to encourage residents to bag their leaves rather than raking them into the street which might lead to a stormdrain blockage. A copy of this flyer is at Attachment MN-17 to Concord’s FY 2005-06 Annual Report. Concord also ran a community service announcement on public access television reminding resident to bag their leaves. There is a sample flyer that was given to residents at Attachment 250.

With 15,365 trees on our streets and 35,000 trees in our parks, Concord is known as a Tree City USA. in recognition of our sustained commitment to our large urban forest. During the heavy leaf season, from the first week in September to the second week in December, crews operated a towed sweeper in addition to our three regenerative air vacuum sweepers. They hauled 82 dump truck loads with 665,260 pounds of leaves directly to the transfer station in Pittsburg. That is over half a million pounds of organic material that would have otherwise gone into our local creeks, delta, and bay. Higher levels of organic matter in a body of water lower the amount of dissolved oxygen because decomposition of plant detritus fuels microbial populations, increases the oxygen demand of sediments, and promotes hypoxia levels. The result can be an atrophic creek, in which large amounts of decomposing organic material completely deplete the available oxygen needed by fish and other aquatic life. Attachment 227 has a day-by-day record of the amount of leaves picked up by Concord’s leaf machine. Attachment 311 shows Concords leaf machine in action.


Goal: Ensure proper handling and disposal of materials removed from streets to prevent discharges of pollutants to surface waters or groundwater.



Street sweeping materials are recycled as green waste. Concord Disposal Service handles all the material removed from the streets in Concord’s street sweeping program. Concord Disposal has an exclusive franchise in Concord through 2011 with an option for the company to extend through 2016. Concord Disposal is described in much more detail in Concord’s FY 2005-06 Annual Report.


Goal: Inspect, and clean, as necessary, public storm drainage facilities (i.e., inlets, V-ditches, pump stations, open channels, and watercourses), once a year on average unless an alternative schedule is approved as described in MUNI-21. The inspections and needed cleaning will preferably occur prior to the rainy season. In calculating this average, some facilities may be inspected more than once per year and others less than once per year.

POC: Bruce Good, Infrastructure Manager [email protected] , (925) 671-3045


The City of Concord has a GIS database of the storm drainage system. The database shows the location of catch basins and pipes, the size of pipes, the type of pipes, the direction of flow, and other information. There are additional GIS layers that show

MUNI - 12



streets and highways, property lines, addresses, zoning laws, creeks and channels, property owners, easements, elevation contours, and aerial photographs. A printout from the GIS system showing all the stormdrain facilities in Concord is at Attachment MN-38 to Concord’s FY 2005-06 Annual Report

Catch basin cleaning is simplified by the use of standard designs. All catch basins constructed in Concord must conform to exacting measurements and specifications. Attachments MN-61, MN-62, MN-63, and MN-64 to Concord’s FY 2005-06 Annual Report have samples of standard design specifications for catch basins in the City of Concord.

Our annual catch basin inspections continue to show a relatively clean system. All 5,600 storm drain inlets were inspected and cleaned at least once in addition to 2 miles of v-ditches and open channels, and 11 miles roadside ditches, and watercourses including inlets, culverts, and trash racks. Attachment 235 is a report from the City of

Concord Performance Based Budgeting objectives, tasks and performance indicators for the municipal drainage systems maintenance program. Some of the parts of the stormwater drainage system that were inspected in our annual program were catch basins, storm drain inlets, flow control structures, creeks, lakes, and ponds. In Fiscal Year 2006-07, there were a total of 16,403 inspections performed by maintenance services personnel. Attachment 251 has a log of the roadside ditches to be cleaned. Attachment 273 has a log of the concrete-lined channels to be cleaned.

Inspectors looked for high sediment levels, missing components, and any other drainage problems. Most of the time, the only maintenance that needed to be done was the removal of excessive sediment. Annual inspection and maintenance costs of catch basins for Fiscal Year 2006-07 totaled $94,251. This included $93,392 in labor costs for City of Concord maintenance crews. City crews expended a total of 2,725 labor hours on catch basin maintenance.

Annual inspection and maintenance costs of drainage ditches for Fiscal Year 2006-07 totaled $149,909. This included $128,747 in labor costs for City of Concord maintenance crews. City crews expended a total of 3,656.25 labor hours on drainage ditch maintenance.


MUNI - 13

Goal: If it is necessary to inspect and clean public storm drainage facilities (i.e., inlets, V-ditches, pump stations, open channels, and watercourses), less than once a year on an annual average, the rationale for the alternative standard must be described in a written action plan. The rationale should demonstrate the alternative schedule is equivalent in terms of protecting water quality as the annual average inspection. The action plan will be submitted to the Regional Board as part of the Annual Report. The alternative standard will not be effective until approved by the Regional Board’s Executive Officer, and approval will be presumed unless it is rejected in writing within 90 days of its submittal.



All public storm drainage facilities, including inlets, V-ditches, open channels, and watercourses, are cleaned at least once a year. This represents a significant commitment to the proper maintenance of all drainage systems at a cost of $324,925 for Fiscal Year 2006-07. Attachment 312 has a copy of the 2006 V-Ditch Cleaning Worksheet describing the dates and locations of v-ditch cleaning.


Goal: When cleaning storm drain inlets and lines, remove the maximum amount of material at the nearest access point to minimize discharges to watercourses.



Storm drain inlets are cleaned using a VaCon vactor truck. Concord's Vactor truck has a 15-yard debris tank and 1,500 gallon water tank. Using a 2-stage centrifugal compressor, this unit is capable of vacuuming debris from great depths and significantly increasing debris volume and velocity. The 8-foot boom lets the operator position the 8” suction tubes up to a 90-degree angle at far reaches from the truck. The water pump delivers up to 80 gpm @ 2,500 psi for jetting operations. The 800’ hose reel rotates for optimum positioning for jet rodding drainage pipes.

Two-person crews are trained to remove as much material as possible from each storm drain inlet. Catch basins are inspected annually and cleaned as necessary. Inspections and cleanings are recorded in an excel spreadsheet. Because of their design or location, some storm drain inlets must be cleaned several times during the rainy season. A look at the annual cleanings done for Fiscal Year 2005-06 shows that the big cleaning began in October and extended into April because of the heavy rains in March this year. Normally catch basin cleaning doesn’t extend through March into April.

MUNI - 14




Goal: Develop a storm drainage facility inspection and maintenance plan. The plan will include: Schedule for inspecting storm drainage facilities; Rationale for determining when to clean inlets, etc.; Identification of target areas that tend to accumulate excessive pollutants for sweeping; and, Inventory of the major storm drain system.



Attachment MN-70 to Concord’s FY 2005-06 Annual Report has a copy of the City of Concord Storm drainage facility annual drainage maintenance program. The Annual

Drainage Maintenance & Inspection Plan is reviewed each Spring to set for the next budget year the schedule for the work to be done in the drainage systems. The maintenance program is based on four priorities: avoiding flood losses, preventing erosion, preserving water quality, and maintaining creek ecosystems.

Concord’s drainage system consists of:

Roadside ditches, swales, and curb leading into the catch basins 5,600 drain inlets/catch basins 98 concrete V-ditches at 64 locations 150 miles of pipe conveying the water into creeks Three major creeks: Galindo Creek, Mt Diablo Creek, Holbrook Channel

The annual drainage maintenance program contains a month-by-month schedule for storm drainage maintenance activities.

The City of Concord has a GIS database of the storm drainage system. The database shows the location of catch basins and pipes, the size of pipes, the type of pipes, the direction of flow, and other information. There are additional GIS layers that show streets and highways, property lines, addresses, zoning laws, creeks and channels, property owners, easements, elevation contours, and aerial photographs. A printout from the GIS system showing all the stormdrain facilities in Concord is at Attachment MN-38 to Concord’s FY 2005-06 Annual Report.


Goal: Unless provided for in an alternative plan approved by the Regional Board’s Executive Officer, inspect and clean as needed public storm drainage facilities that have been identified to accumulate excessive pollutants twice a year. Preferably, inspections will occur prior to and after the rainy season to prevent flooding and discharge of pollutants.

MUNI - 15




All of Concord's public storm drainage facilities are inspected each Fall, before the winter rains. Those that need cleaning are cleaned. Any that need repair are repaired. Heavy winter and spring storms require that crews repeatedly clean certain catch basins prone to sedimentation. All of the problematic drainage facilities are inspected after each storm. Those requiring attention are cleaned before the next storm to capture accumulated material before it is washed downstream. Concord's proactive inspection and cleaning programs have dramatically reduced pollutant transportation and property damage from flooding.

MUNI - 16



Goal: Inspect storm drain inlets monthly during the wet season in areas suspected of illegal dumping, and clean as necessary.



Storm drain inlets are inspected before the rainy season and after each major storm. Areas prone to problems are inspected more frequently. Attachment MN-71 to Concord’s FY 2005-06 Annual Report shows the annual catch basin cleaning program for Zone 1. Attachment MN-68 to Concord’s FY 2005-06 Annual Report is a list of known problem catch bins. As problem areas are identified, they are added to the list for increased monitoring.


Goal: When sweeping over storm drain inlets, prevent pushing debris into the inlet.



The Tymco 600 regenerative air sweeper vacuums debris with a high-suction central pick-up head. Unlike older sweepers, the Tymco 600 does not push debris into drain inlets. There is an exhaustive description of the Tymco 600 sweeper in Concord’s FY 2005-06 Annual Report. Attachments 187 and 188 have more information on Tymco 600Regenative Air street sweepers.


Goal: Report the amount of material removed when cleaning storm drainage facilities.



Attachment 239 is a sample page from our FY 2006-07 annual storm drainage facility cleaning program for Zone 1.

Frequent inspections resulted in a relatively clean system. All of 5,600 storm drain inlets were inspected and cleaned at least once in addition to 11 miles of v-ditches, open channels, roadside ditches, and watercourses including inlets, culverts, and trash racks.

MUNI - 17





Goal: Document and track responses to spill incidents.



Attachment 241 has a database on every spill or illegal dumping incident. Attachment 240 has a GIS map of every spill or illegal dumping site coded by type material dumped or spilled.

On Sunday, August 20, 2006 Public Works staff provided assistance after a tandem tanker truck overturned and leaked fuel adjacent to the on-ramp from eastbound Hwy 4 onto southbound Hwy 242. Multiple fire departments, CHP, Concord PD, Caltrans, and hazmat crews were also involved in this event, during which approximately 700 gallons of fuel was spilled. Public Works staff identified the City storm drains that the Caltrans storm drains tie into and assisted the hazmat crews in locating the affected structures. The fuel just barely entered into the City storm drain system and no fuel made its way into Holbrook Channel. Hazmat did a very thorough job cleaning up our one affected catch basin.


Goal: Track storm drain inlets which require more frequent cleaning.

Goal: Document and maintain the following records: Areas/sites inspected; Silt and vegetation quantities removed; Man-made materials removed, and type and estimate of volume removed; Disposal practices and follow-up actions; Spill incidents and follow-up actions; Application of chemicals (type used, areas applied); and, Areas for possible improvements.



Public Works - Maintenance Services staff tracks areas and sites inspected in the annual creek maintenance programs, in the annual catch basin cleaning program, and in the unscheduled cleaning done after major winter storms. Staff reports to California Fish and Game Department the amount of silt, vegetation, and man-made materials removed from the creeks. Attachment 208 has a copy of our 1602 Streambed Alteration Agreement. Attachment 207 describes the conditions of the agreement.

The City of Concord partnered with residents who live along creeks to clean up private portions of the creeks. Attachments 279 and 280 explain this program in greater detail.

The City Clean Water Program Manager tracks spill incidents and follow-up actions.

All application of chemicals are tracked and documented by professional Pesticide Applicators working for the City. Chemical usage is reported to the County Agricultural Advisor in accordance with guidance from California Department Pesticide Regulation.


Goal: A plan for the storage, use and disposal of hazardous materials will be developed and implemented to insure these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management. Disposal of the material will be at an appropriate facility.

Several different educational materials are used to reinforce employee training sessions. Three sample BASMAA pamphlets are at Attachment 306-308.



MUNI - 20



Attachment MN-72 to Concord’s FY 2005-06 Annual Report is a City of Concord pollution prevention plan that addresses storage, use, and disposal of hazardous materials in a safe manner to avoid the possibility of stormwater pollution. The plan identifies potential sources of hazardous materials that could affect the quality of storm water discharged from the site. The plan also describes the best management practices to reduce or prevent pollutants in the storm water discharge. Any hazardous materials are consigned to Romic Environmental Technologies Corporation http://www.romic.com/ for transportation and disposal. Attachment 262 shows pictures of one such shipment.


Goal: If a spill is suspected to be toxic or a hazardous material, maintenance staff will call the public safety dispatcher, 911, County Hazardous Material Program and/or appropriate designated personnel.



Spills are reported immediately to ensure that the environment is protected. Crews are trained to respond quickly to all spills particularly those that could do environmental damage if response is delayed; i.e., large spills, spills of hazardous materials, spills reaching waterways or storm drains, multi-jurisdictional spills. These have the potential to harm human health and the environment. They are reported immediately to Contra Costa County Hazardous Materials (HazMat).

Attachment MN-28 to Concord’s FY 2005-06 Annual Report is a Spill Response Flow Chart showing actions to be taken and notifications to be made in the case of a spill. This flow chart was distributed to maintenance supervisory personnel and used in crew training. Attachment MN-26 to Concord’s FY 2005-06 Annual Report is an Illicit Discharge Phone Tree. Each section of Public Works has a copy of this phone tree which readily identifies the agencies and individuals to be contacted in case of a spill.

Agencies listed to contact include: After Hours Concord Pd Dispatch: 671-3333 Central Contra Costa Sanitary District: 24 Hour Line (925) 933-0955 Household Hazardous Waste Collection Facility: Toll Free 1-800-646-1431 East Bay Regional Park District - Fire District 24 Hour Line: (510) 881-1121 San Francisco Bay Regional Water Quality Control Board: (510) 622-2300 Central Valley Regional Water Quality Control Board: (916) 464-4730 Cal.

Goal: If non-hazardous materials are spilled, maintenance staff should contain the spill area immediately to prevent additional dumping and discharge of pollutants into the storm drain system and sweep as soon as practicable.



The practices commonly followed for minor spills are to:

1. Contain the Spill Stop the source of the spill. Berm around spill area if necessary. Use absorbent materials to prevent spreading of spill area if available.

2. Recover Spilled Material Sweep up spilled dry materials immediately. Never attempt to "Wash them

away" with water, or bury them. Recover liquid spills on dirt areas by digging up and properly disposing of

contaminated soil. Recover liquid spills on paved or impermeable surfaces using "dry" cleanup

methods (absorbent materials and/or rags).

3. Clean the Contaminated Area and/or Dispose of Contaminated Materials Used cleanup rags may be hazardous wastes that must either be sent to a

certified industrial laundry or dry cleaner, or disposed of properly. Dispose of contaminated materials in a proper waste container. Make sure that toxic liquid wastes (used oils, solvents, and paints) and

chemicals (acids, pesticides, additives and curing compounds) are not disposed of in dumpsters designated for construction materials.

Place small non-hazardous spill residues and materials inside a sealed container and place into the garbage can or dumpster.

Examine labels of spilled materials for proper waste disposal instructions. Inspect the spill area periodically until it can be satisfactorily determined that

the spill material has been completely removed from the site.

MUNI - 22



Goal: Establish response/removal procedures for spills after work hours with appropriately designated personnel.



Concord has a 24-hour stand-by maintenance crew designated each month to respond to spills during the hours the City offices were closed. Attachment 243 contains detailed instructions for incidents that occur after normal working hours.


Goal: Maintenance staff will report measurable spills to and work with appropriately designated personnel to determine the proper follow-up response.



The spill response plan is at Attachment MN-28 to Concord’s 2005-06 Annual Report. In accordance with this plan, personnel who first arrive at the scene perform initial substance identification, attempt to determine responsible party, and scope of spill. Personnel also check for labels on containers, if there are any. If the spill is an unidentifiable material, multi-jurisdictional in scope, entering a stormdrain or waterway, or potentially impacting public health or environment, personnel stop the source of the spill and block access to stormdrains until HazMat/Emergency responders arrive to relieve the crew.

In cleaning up dry spills, crews scoop & sweep up dry material immediately, place materials into containers and never hose down or bury dry materials. In cleaning up liquid spills, crews absorb liquids using absorbent materials such as rags, loose absorbents (e.g., kitty litter), mats, and pillows. Wash water must not enter the storm drain. If wash water is used for clean-up, it must be collected & properly disposed of, i.e., absorbed or vacuumed.


Goal: If appropriate, maintenance staff will notify appropriate designated personnel and agencies for possible future enforcement action.



MUNI - 23




Crews are instructed to notify the City of Concord Clean Water Program Manager in the event of a spill. The Clean Water Program Manager works closely with the Concord City Attorney on prosecution of responsible individuals in the case of spills. Each case is judged on its own, individual merits. Circumstances surrounding the spill, past history of the individual or business, and environmental consequences of the incident are all taken into account with deciding on a course of action to prevent future spills. In some cases, the result has been a civil administrative fine. Other, more serious, cases were referred to the Contra Costa County District Attorney's office for prosecution. Some of these cases involved civil penalties and others involved criminal charges.


Goal: Instead of flushing streets and allowing water to drain into storm drain inlets when steep and narrow streets exist and where it is difficult to use a street sweeper or vacuum: Encourage residents to maintain streets by removing leaves, litter. If flushing streets or sidewalks, protect the storm drain inlet, and remove materials using vacuum equipment or by some other appropriate means to remove residual material and water to the maximum extent practicable.



City Crews do not flush streets with water. In the case of chemical spill, crews use absorbent pads and excelsior to soak up the spill. The contaminated materials are disposed of as hazardous waste. In the case of litter or leaves, city crews use vacuum sweeper trucks to pick up the material.


Goal: When cars are left on the street: Consider posting restricted parking signs on sweeping days to increase accessibility; post temporary signs to remove cars and sweep according to posted schedule; and, protect the storm drain inlet, and remove material using vacuum equipment or by some other appropriate means to remove residual material and water.



A novel method devised to deal with areas heavily impacted with parked cars employs a staff member with a hand held blower to move debris from the gutter line to the middle of the street just prior to the passage of the street sweeper. This practice has shown considerable merit. On streets that are heavily impacted by parked cars, Concord crews use a two-person system to blow litter and debris out from underneath the parked

MUNI - 24



vehicles to the center of the street where a vacuum sweeper picks it up. This is the best system found so far to use in neighborhoods with large numbers of apartment buildings. Streets are typically targeted for “blowing out” once a month.

PS-17 has a description of Concord’s new, unique street sweeping signs.

Concord’s “Clean Streets Team” uses windshield fliers with English instructions on one side and Spanish instructions on the other. A sample of the English and Spanish instructions is included at Attachment 215.


Goal: Inspect pump stations after the wet season and develop a time schedule for maintenance activities prior to the next wet season.



There are no stormwater pump stations in the City of Concord.

If one is installed in the future, City crews will inspect it after the wet season and develop a time schedule for maintenance prior to the next wet season.


Goal: Inspect trash racks and/or oil absorbent booms after significant storms. Remove debris in trash racks and replace oil absorbent booms as needed.



Concord’s one trash rack is inspected and cleaned after each winter storm to ensure their continued serviceability and effectiveness.


Goal: Comply with the regulatory requirements of the appropriate agencies (e.g., California Department of Fish and Game, the U.S. Army Corps of Engineers, etc.).



MUNI - 25




The City of Concord has agreements with California Fish and Game for routine creek maintenance. Routine creek maintenance involves removal of debris and vegetation from the waterway.

In accordance with instructions, Concord staff conducted water quality testing at the dog off-leash area in Newhall Park. Water samples were taken at the drainage collection point for the dog park and at a point upstream in the creek in Fall 2006 after the first major rain event. Attachment 336 is a chain of custody form showing how and where the samples were collected. An independent laboratory, Sequoia Analytical, tested both samples for total coliforms. Test results for all samples were identical -- greater than the 2400 MPN/100mL -- the upper detection limit for total coliforms. This result was the same both upstream and downstream of the dog park. The coliforms count has been the same upstream and downstream every year since the dog park opened four years ago. This indicates that the dog park is not contributing contamination to the receiving waters of Galindo Creek. Attachment 337 has photographs showing exactly where and how the samples were collected. Attachment 338 is an official report with the test results from Sequoia Analytical.


Goal: Identify illegal dumping hot spots. Conduct regular inspections, postings and sweep-up to discourage additional dumping incidents. Consider appropriate actions to prevent illegal dumping.

POC: John Rego, Parks Program Manager [email protected] , (925) 671-3445


City crews identify possible problem areas for illegal dumping. These areas are checked often by streets and parks crews during the normal course of the workday. Additionally, the City of Concord has several special hotlines for City crews, residents, and businesses to report different kinds of illegal dumping:

Attachment 240 shows all of the cases of illegal dumping in Concord in FY 2006-07

Dumped material is cleaned up within 24 hours after it is found or reported.

To prevent illegal dumping, there is a special crew scheduled to work from 7:00-11:00 a.m. in the downtown area. They wash park furnishings in Todos Santos Plaza, blow off all sidewalks, wash the stage area, remove all debris, chip off chewing gum from park furnishings and sidewalk areas, clean the playground, pick up cigarette butts and rake the decomposed granite. The crew then cleans the following downtown streets: Salvio St., Grant St., Adobe St., Mt. Diablo St., Colfax St., and Mira Vista Terrace.

MUNI - 26


During the afternoons, the crew is assigned to litter removal on major arterial streets, and creek cleaning.

MUNI - 27


Goal: Coordinate with appropriate personnel and agencies to enforce laws in targeted areas to prevent illegal dumping.



This year, Concord joined a high-level, multi-agency task force organized by County Supervisor (now State Senator) Mark DeSaulnier to develop procedures for cleaning up homeless encampments along Contra Costa County Flood Control channels such as the Walnut Creek Flood Control Channel. Other task force members included: Pleasant Hill, East Bay Regional Park District, County Flood Control, County Mental Health, County Homeless Program, County Sheriff, and the County Administrator’s Office.

Homeless encampments along flood control channels, especially under the bridges that span those waterways, are a recurring problem in this area and one that requires close coordination and cooperation between the Flood Control District, Social Services, law enforcement, and crews to clean up the debris. There are numerous clean water issues, health and safety issues, and flood control issues associated with these encampments and the debris that they accumulate under the bridges when these encampments become established for any length of time. The task force established a protocol for coordinating these cleanups.

County Social Services provides outreach to the homeless prior to the cleanup action, advising them where shelter and counseling were available, the cleanup dates were posted at the encampments along with a phone number to call for additional information, the cleanup was conducted by personnel from the Phoenix program, using dumpsters provided by the jurisdiction where the encampments were located, and with law enforcement personnel present during the posting and cleanup operation.

Pictures from two homeless encampment cleanups are at Attachments 333 and 334.


Goal: Evaluate additional areas for use of trash racks, oil absorbent booms, outlet protection, etc. to reduce pollution to watercourses.



MUNI - 28



Staff annually evaluates the use of trash racks, absorbent booms, and drain inlet protection to reduce pollution in stormwater runoff. This evaluation is done in concert with the annual creek and drainage systems program of inspection, cleaning and maintenance.


Goal: Minimize desilting activities and disturbances of channel bottoms during the wet season.



City crews scheduled all creek work to be completed before the wet season. No work was done in the creeks after October 15, 2006 including desilting activity or channel bottom disturbances.


Goal: Dispose of desilted material properly and do not allow it to re-enter the watercourse after removal to the maximum extent practicable.



It is standard practice that any material recovered from desilting operations is hauled overland by truck to the landfill.


Goal: Retain (design approved) low growing vegetation in channel bottoms and slopes to detain runoff, minimize erosion, and trap sediment, and enhance riparian habitat when evaluating the need to maintain channel design capacity, as appropriate.



Attachment MN-73 to Concord’s FY 2005-06 Annual Report is a letter to Concord residents annually explaining the proper way to clean riparian areas. This letter was sent to all owners of property that abuts a creek in Concord. The letter contains specific guidance on material to remove form the creek and material to leave in the creek. In addition to the text, illustrations are used to ensure that there is no misunderstanding.

MUNI - 29




Invasive species were targeted for removal to promote the establishment of native ground covers. Pervasive plant invaders and other woody species were removed. Herbaceous species were pulled by hand. Removing these invasive species was a key step in promoting a diversity of protective ground-layer vegetation and encouraging regeneration of native trees and shrubs.

Live staking was used to reestablish vegetation and help stabilize selected slope areas. The live stakes, mostly willow, were cut in nearby natural areas along the creek. Live staking was most successful in areas that are relatively unshaded and remain wet as a result of seepage and springs in the area.

Seedling trees were planted in other areas to help stabilize slopes and re-vegetate the area with native trees. Herbaceous species were transplanted to eroding slopes. Plant roots will help hold the soil in place.


Goal: Require an adequate number of litter receptacles in commercial areas and other litter source areas.



We have received very positive reaction to the new litter receptacles on Monument Boulevard. Using grant funds from the California Beverage Container and Litter reduction program, five litter receptacles were purchased to help reduce litter in the most impacted areas. Grant funds are being used to have the receptacles emptied twice a week by Concord Disposal. Any cleaning and graffiti removal is provided by Public Works staff. We placed these containers two weeks ago and the feedback has been uniformly favorable. The receptacles are located at:

1199 Monument Boulevard at the bus stop on the north-west corner with Victory Lane

1290 Monument Boulevard at the bus stop 1360 Detroit Avenue at the bus stop in front of the child care center 1500 Monument Boulevard at the bus stop by Kragen Auto 1551 Monument Boulevard. between Wendy's and Mora's Boots 1611 Monument Boulevard near 7-11 at Lacey Lane at the bus stop 1661 Monument Boulevard. at the bus stop near 4 Corners Liquor 2050 Monument Boulevard. at the bus stop in front of Orchard Hardware 2550 Monument Boulevard at the bus stop Corner of Detroit and Sunshine at the bus stop in front of Meadow Homes

Park The corner of Treat Boulevard & Oak Grove Rd., at the bus stop adjacent

to the Shell gas station

MUNI - 30


Eight litter cans are along Monument Boulevard. Four were installed with 2005 grant funds. These are shown as yellow flags in a green circle. Another four were installed with 2006 grant funds. These are shown as yellow flags without the green circle.

One litter can was installed near the intersection of Treat Boulevard and Oak Grove Road

Two litter cans were installed on Detroit Avenue

MUNI - 31

The litter receptacles are part of a larger Public Works Program to reduce litter in Concord. This program also includes:

Flyers, and educational give away materials Articles in City News, City Talk, and the Contra Costa Times Booths at Music at Noon, Home and Garden Shows, etc. Light pole banners Announcements on community access television Reminders at creek group and neighborhood meetings Annual creek cleanup days

Grant funds are also being used to have the receptacles emptied twice a week by Concord Disposal. Any needed cleaning or graffiti removal has done by Public Works staff.


Goal: Require the pick-up of litter receptacles on a frequent basis to minimize or prevent spillage.


Date Started: 07/01/2006 Date Complete: 07/01/2007 Status: CompleteConcord has 23 public parks. Attachment MN-40 to Concord’s FY 2005-06 Annual Report has a guide showing the location of, and amenities provided at each of these parks. Each park has numerous litter receptacles. City crews emptied these receptacles six days a week.

MUNI - 32

Receptacle at the bus stop on Monument Boulevard


Concord’s downtown area was equipped with litter receptacles. These receptacles were emptied daily -- at least six days a week. Special attention was given to the receptacles in front of high litter businesses such as the Brendan Theater. The receptacles near high litter businesses were emptied more than once a day.


Goal: Promote public education efforts to include an anti-littering message. Specifically, encourage: 1) residents to compost yard waste; 2) residents and businesses to remove litter from their property and properly contain waste; and 3) owners of loading docks, restaurants and other litter source areas to sweep outdoor areas daily and properly contain waste.



City of Concord was recognized by American Public Works Association, Northern California Chapter for an outstanding litter reduction program. A copy of the award is at Attachment 115. Concord’s sweeping program was recognized as a “Government Best Practice” by SustainLane (www.sustainlane.com/) a community powered directory of green products, businesses and reviews. Attachment 192 has a screenshot of the webpage.

Staff developed a tri-fold pamphlet in English and Spanish explaining ways to reduce neighborhood litter. Copies of these pamphlets are at Attachments MN-05 and MN-06 to Concord’s FY 2005-06 Annual Report. These anti-litter pamphlets were distributed at neighborhood association meetings as well as racks at city hall, the library, Public Works-Maintenance Services, the Police Department, Public Works-Engineering Services, the Permit Center, and the Finance Department.

There is a recently updated page devoted entirely to litter on Concords web site at http://www.ci.concord.ca.us/living/recycle/env-litter.htm

This year, Concord displayed 200 street pole banners with the message “Keep Concord Beautiful – Don’t Litter.” Attachment 116 shows a sample of the banners. These banners were deployed throughout the City to remind residents, commuters, pedestrians, and others not to litter.


Goal: Encourage appropriate personnel and agencies to post signs and enforce anti-littering laws.

Personnel from the City of Concord Neighborhood Preservation Division, Police Department, Public Works Department, and the Redevelopment work with businesses, individual residents, neighborhood groups, nonprofit groups, and other government agencies to reduce litter. Attachments 244 to 247 show some of the signs used in this effort.

Some businesses like Royal Trucking and Granite Construction hire private sweeping companies to clean around their business every week. Other businesses like 7-11 on Monument Boulevard have employees patrol the parking lot several times a day to pick up litter. Concord encourages and supports these efforts.


Goal: Document and maintain the following records: Areas targeted for litter removal, and Total amount of material removed.



Using the Sheriff's Work Alternative Program, the following areas were targeted:

Litter control in open space areas, creeks, and city-owned lots, trails and parks; Sidewalk sweeping along major arterial streets and the downtown area; and Litter control-in parks, municipal parking lots, downtown streets and curb lines.

In Fiscal Year 2005-06 the Sheriff's Work Alternative Program had an average of six people per day. Crews removed more than eight tons of debris illegally dumped on major arterial streets.

Coastal Cleanup day on September 16, 2006 is described in Attachment 341. Forty-nine volunteers worked for three hours to clean two miles of creeks. They collected 550 pounds of trash and 200 pounds of recyclable material including:

31 plastic bags 139 plastic bottles 321 cigarette butts 125 food wrappers 13 soda straws 63 beverage cans 32 glass bottles

Goal: Take reasonable and practicable measures to protect the storm drain inlets (such as, tarps in work areas, sandbags, booms or barriers around stormwater inlets) prior to removing graffiti from walls, signs, sidewalks, or other structures needing graffiti abatement. Clean up afterwards by sweeping or vacuuming thoroughly, and/or by using oil absorbent and properly disposing of the absorbent.

POC: Alton Baxley, Facility Manager [email protected], (925)671-3025


Concord had an aggressive, environmentally sensitive, Graffiti Program with a goal to remove 95% of graffiti within 24-hours after it is found anywhere in the City -- on public or private property.

The graffiti was removed by spraying cleaners from a ½ quart spray bottle. These cleaners are then wiped from the surface with an absorbent cloth. For large areas, graffiti was covered by painting over it with latex paint. If high-pressure water was needed, the stormdrains were first protected to the maxim extent practicable.

In 2006-07, crews removed 15,719 incidents of graffiti at a cost of $119,777. Of these, 100% were removed within 24-hours. Attachment 248 has more details from the Performance Based Budgeting system.


Goal: Prohibit the discharge of debris, sweeping compound waste, paint waste, or wash water containing sweeping compounds to the storm drain.



City of Concord Municipal Code paragraph 86-32 states in part “Unlawful discharge. Any discharge to the City's stormwater system that is not composed entirely of stormwater, except discharges pursuant to an NPDES permit, discharges resulting from fire fighting activities and discharges further exempted in section 86-35 of this article."

Paragraph 86-35(a) further states “The release of non-stormwater discharges to the city's storm system is prohibited."

MUNI - 35




Goal: Direct runoff from all types of sand blasting and high pressure water (no cleaning agents) washing activities into a landscaped or dirt area. If a landscaped area is not available, filter runoff through an appropriate filtering device (e.g., coarse sand bags or filter fabric to keep sand, particles, and debris out of storm drain).



City crews were equipped with truck-mounted vacuum equipment. All runoff from high-pressure washing or sand blasting was captured with the vacuum equipment and transported to the sanitary sewer for disposal.


Goal: Avoid conducting graffiti abatement activities during a rainstorm. If it rains during graffiti abatement activities unexpectedly, take appropriate action to minimize the impact on the quality of stormwater (e.g., divert runoff around work areas).



Graffiti abatement was not done when it is raining. City crews waited for a break in the weather before proceeding with graffiti removal.


Goal: Train employees and volunteers conducting graffiti abatement in using these performance standards. Incorporate these performance standards into agency contract specifications. Provide volunteers and contractors conducting graffiti abatement with educational material describing the graffiti abatement performance standards.



Concord uses the BASMAA Qualified Consultant List at Attachment 315 when reviewing contractors’ qualifications.

Employees are trained in five ways:

MUNI - 36




The Stormwater Program Manager made presentations to staff. The presentations cover current and future stormwater pollution prevention practices as well as history of the stormwater program and a little about the philosophy behind regulation efforts.

The Stormwater Program Manager visited employees once a quarter on average. During these individual visits, he answered questions about anything to do with the stormwater program and find out if more guidance is needed in a particular area.

The graffiti abatement section had biweekly tailgate safety meetings to discuss current events and issues. At this meeting, the supervisor passed along information learned from the Contra Costa Clean Water Program.

Information, documents, and guidance were disseminated to the employees via email. All of the employees have access to computers and an email account. This was often found to be the fastest, most direct was to ensure that everyone gets the word about stormwater changes.

Staff continues to distribute educational pamphlets and materials to employees as well as the public. Many of the brochures are included as attachments to this report.

The City of Concord did not use volunteers to remove graffiti. Professional City employees did all graffiti removal.


Goal: It is recommended one supervisor/management-level person be assigned the responsibility for ensuring these performance standards are implemented.



The Facilities Maintenance Division of the Parks and Recreation Department has two full-time managers assigned. One of the managers is always on duty when graffiti eradication operations are underway. Managers meet with the crews before the start of each shift to reinforce safety, environmental, and customer concerns before distributing work assignments.


Goal: Clean equipment used for graffiti abatement activities in accordance with the performance standards.



MUNI - 37



Equipment used for graffiti abatement is cleaned and maintained in accordance with manufacturer specifications. Vehicles are washed in a covered wash area on a concrete pad that is sloped to drain internally to a sanitary sewer drain. Attachment MN-24 to Concords FY 2005-06 Annual Report shows pictures of the vehicle wash rack being used to wash maintenance equipment.


Goal: Dispose of cleaning compounds in accordance with the corporation yard’s Stormwater Pollution Prevention Plan (SWPPP).



Cleaning compounds are collected at a central location for disposal by a commercial company on a hazardous cargo manifest.

The City of Concord municipal Stormwater Pollution Plan (SWPP) includes information on facilities, procedures, staffing, technology, and equipment. The facilities were reviewed to add new pieces; e.g., buildings, drainage structures, and pavement. Staff reviewed the plan for adequacy, standardization, proper documentation and current staffing to identify changes in roles and responsibilities. This review also included a review of new technologies and Best Management Practices (BMP) for possible implementation.

Attachment MN-25 to Concord’s FY 2005-06 Annual Report contains a copy of the City of Concord Corporation Yard Stormwater Pollution Prevention Plan (SWPPP)


Goal: Consider using a waterless chemical cleaning method for graffiti removal (e.g., gels or trigger spray compounds).



Graffiti was typically removed with a cleaner applied from a ½ quart spray bottle. These cleaners are then wiped from the surface with an absorbent cloth. For large areas or surfaces not appropriate for a spray bottle, graffiti was covered by painting over it with latex paint.

MUNI - 38




Goal: If using a graffiti abatement method that generates wash water containing a cleaning compound (such as high-pressure washing with a cleaning compound) protect storm drains and dispose of materials properly.



Storm drains were always protected in cases where high-pressure spraying was used. Storm drains were covered with plastic or other impervious material. Runoff was vacuumed up with a truck-mounted wet vacuum. The runoff was transported, via truck, to the sanitary sewer for disposal.


Goal: Schedule excavation and road maintenance activities for dry weather, if feasible.



Scheduled road maintenance was always done in dry weather. Unscheduled maintenance, like pothole repair, was done in dry weather unless it posed a threat to public safety. If the condition posed a threat to public safety that couldn't wait for the weather, City crews put a temporary patch that would last through the rainstorms. After the rainstorms were over, crews would return to make a permanent repair.


Goal: Perform major equipment repairs at the corporation yard, when practical.

POC: Charles Rickenbacher Fleet Manager [email protected], (925)671-3147


In Fiscal Year 2006-07 major equipment repairs were always done at the City Corporation Yard. The City of Concord has a vehicle maintenance facility with six indoor bays for general-purpose vehicle maintenance and repairs. There are also two bays designed for allied trades like tires, glass, and bodywork. City of Concord mechanics performed most routine work in-house. Major repairs like engine overhaul and specialized work like windshield replacement were almost always contracted out to specialized companies.

MUNI - 39





Goal: When refueling or maintaining vehicles and equipment on-site, use a location away from storm drain inlets and creeks.



No vehicles were maintained or refueled at the work site. All vehicle maintenance and refueling was done at the city Corporation Yard.

The City of Concord and the Police Department had fuel pumps for gasoline. Neither of these fueling points is located near storm drain inlets or creeks. Compressed natural Gas (CNG) and diesel vehicles refuel at commercial gas stations.

Fueling areas were paved with concrete rather than asphalt. Fueling pumps had vapor recovery nozzles to control drips. All vehicles were parked so that spills or leaks can be contained. There are signs and training to discourage "topping off" fuel tanks. Attachment MN-90 to Concord’s FY 2005-06 Annual Report shows a sign on the fuel pump saying “Do Not Top Off”

Vehicle Maintenance personnel use the Contra Costa County Green Business Auto Pollution Prevention Checklist at Attachment MN-87 to Concord’s FY 2005-06 Annual Report.


Goal: Recycle used motor oil, diesel oil, concrete, broken asphalt, etc., whenever possible.



All used motor oil, antifreeze, and hydraulic fluid was picked up at the Corporation Yard and recycled by a commercial company. Asphalt is recycled through County Quarry Products, 5501 Imhoff Drive in Martinez, California.


Goal: Provide proper containment of diesel fuel used to lubricate or clean equipment or parts.


MUNI - 40





If any diesel fuel was used to clean equipment, it was captured in a 55-gallon drum. The drum, when full, is consigned to a hazardous waste hauler for proper disposal.


Goal: Train employees in using these general practices for road repair and maintenance activities.



Employees are trained in proper practices for road repair and maintenance. Pollution Prevention and Good Housekeeping were the key elements of our storm water management program. Employees used drip pans to collect drips and avoid spills and absorbent materials to mop up small spills, and for general cleaning (rather than hosing down the area). The absorbent materials were stored promptly and disposed of by a commercial hazardous waste hauler.


Goal: Take measures to protect storm drain inlets prior to breaking up asphalt or concrete (e.g., cover inlets). Clean afterwards by sweeping all related materials.



Four temporary control measures used to protect storm drain drop inlets are:

Covering inlets; Excavation around the perimeter of the drop inlet; Fabric barriers around inlet entrances; and Block and gravel protection.

Excavation around a storm drain inlet creates a settling pool to remove sediments. Weep holes protected by gravel are used to drain the shallow pool of water that accumulates around the inlet.

A fabric barrier made of porous material erected around an inlet can create an effective shield to erosion sediment while allowing water flow into the storm drain. This type of barrier can slow runoff velocity while catching soil and other debris at the drain inlet.

MUNI - 41



Block and gravel inlet protection uses standard concrete blocks and gravel to form a barrier to sediments while permitting water runoff through select blocks laid sideways.

In addition to the materials listed above, limited temporary storm water drop inlet protection can also be achieved with the use of straw bales or sandbags to create barriers to sediment.

All city crews and construction contractors working for the City were required to conform to the requirements of the “Best Management Practices (BMP) for Construction Sites” as detailed in Section 5907-D of the Concord Municipal Code. Construction personnel must place filter materials to control debris and sediments from entering the City’s stormwater system. A copy of Concord Municipal Code, Article V, Chapter 9, Stormwater Management and Discharge Control can be found online at http://www.cityofconcord.org/citygov/municode/municodeindex.htm


Goal: After breaking up old pavement, remove and dispose of properly.



All asphalt and concrete pavement is recycled. The most often used recycler was County Quarry Products at 5501 Imhoff Drive in Martinez.


Goal: During saw-cutting operations, block or berm around storm drain inlets using sandbags or an equivalent filter device, or absorbent materials such as pads, pillows and socks to contain slurry. If slurry enters the storm drain system, have the material removed to the maximum extent practicable.



During saw cutting operations, city crews sealed any nearby storm drain inlets, captured the water with a vacuum, and transported it to the sanitary sewer for disposal. No saw cut slurry was allowed to enter the storm drain system. Broken asphalt was recycled with County Quarry Products, 5501 Imhoff Drive, Martinez, California.


Goal: Remove saw-cut slurry (e.g., with a shovel or vacuum) before leaving at the end of the day.

During saw cutting operations, City crews sealed any nearby storm drain inlets, captured the water with a vacuum, and transported it to the sanitary sewer for disposal. No saw-cut slurry was allowed to enter the storm drain system. No saw-cut slurry was left at the work site overnight.


Goal: Prohibit the stockpiling of materials in streets, gutter areas or near storm drain inlets or creeks unless these areas are protected.



No material was stockpiled in the streets, gutter, or near storm drains. Material stockpiles were kept at the corporation yard. Only enough material for the work was transported to the site. No material stockpiles were left at the work site overnight.

Performance Standard 074Goal: Protect storm drain openings before applying seal coat, slurry seal, etc. Prevent to the maximum extent practicable material from entering storm drain inlets and sweep up debris, if needed.



Storm drain openings were covered with protective paper before and during paving operations to insure that none of the paving material went down the storm drain. Paving operations included slurry seal, patch paving, deep lift patching, and pothole repair.

City crews did 419,711 square feet of deep lift patching. City crews did 1,540,080 linear feet of crack sealing. City crews applied slurry seal to 5,404,916 square feet of pavement surface. City crews skin patched 177,050 square feet of pavement.

In addition, City crews patched 115 potholes.

All of these paving operations were done in a manner that prevented paving materials from entering Concord's storm drainage system.

MUNI - 43





Goal: Do not wash excess material from exposed aggregate concrete or similar treatments into an unprotected street or storm drain inlet. Designate an unpaved area for sweeping up and proper disposal of excess materials.



City crews did not work with exposed aggregate concrete. Standard operating procedures require that concrete wash water, or wash water from similar operations, be captured and disposed in the sanitary sewer system.


Goal: Agencies will use only as much water as necessary for dust control to avoid runoff.



City of Concord crews always use a minimum amount of water for dust control to avoid runoff.


Goal: Sweep up as much material as possible and dispose of properly. Only wash down streets if runoff is controlled or contained.



The City of Concord uses state-of-the-art vacuum sweepers to clean up any material on the street. Crews do not wash down streets with water.


Goal: Catch drips from parked paving equipment with pans or absorbent material placed under the machines or berm the area around them to the maximum extent practicable.


MUNI - 44






Paving equipment was thoroughly cleaned at the end of each shift. Any contaminated diesel used to clean the equipment was captured in a 55-gallon drum. Drip pans were placed under the equipment whenever there was a possibility of drips. A certified mechanic inspected every vehicle for oil, fluid, or hydraulic leaks at least twice a year.

Mechanics performed 530 inspections for mechanical fluid leaks.

380 Preventative Maintenance inspections of general purpose vehicles 39 Preventative Maintenance inspections of heavy duty vehicles 459 Preventative Maintenance inspections of police vehicles

Any oil or cooling system fluid leaks found in Concord’s vehicle fleet were repaired before the vehicles were returned to service.


Goal: Clean up all spills and leaks from other equipment and work site areas using “dry” methods (absorbent materials and/or rags). Properly dispose of absorbent materials and rags. If spills occur on dirt areas, dig up and remove contaminated soil properly in a timely basis.



City crews used dry methods, by sweeping and using absorbent cleaning agents, to clean work areas instead of hosing them down. Crews swept outside areas regularly and put the debris in the garbage instead of sweeping or hosing it into the street. Crews kept dumpster lids closed and the areas around them clean. Crews did not fill dumpsters with liquid waste or hose them out. Crews promptly called Concord Disposal Services to replace any dumpsters that were found leaking.


Goal: Prior to completion of the job, remove stockpiles (asphalt materials, sand, etc.).



No material was stockpiled in the streets, gutter, or near storm drains. Material stockpiles were kept at the corporation yard. Only enough material for the work was transported to the site. No material stockpiles were left at the work site overnight.

MUNI - 45




Goal: If it rains unexpectedly, take appropriate action to prevent pollution of stormwater runoff (e.g., divert runoff around work areas).



Crews are trained to take immediate action if it begins to rain unexpectedly in the course of paving operations, paving operations are ceased and equipment is covered. Storm drain openings are monitored to ensure that the covers remain intact. If necessary, paper covers are reinforced with plastic and sandbags to ensure that no paving material enters the storm drainage system. Run-on water is directed away from paved areas that are not completely dried. The weather forecast was reviewed before each shift. Paving was postponed when there was a chance of inclement weather.


Goal: Store spill absorbent materials on vehicles to be used in the event of a spill.



Concord Public Works trucks carry absorbent materials and rags for use in the unlikely event of a spill. Crews are trained to soak-up spilled materials with absorbent material, sweep up contaminated material into a sealed container and bring the container back to the corporation yard 55-gallon drum. The drum, when full, is consigned to a hazardous waste hauler for proper disposal.


Goal: Contain and sweep up {Striping} waste materials, and dispose of them properly according to the Material Safety Data Sheet.



Striping waste materials are captured in a 55-gallon drum. The drum, when full, is consigned to a hazardous waste hauler on a hazardous cargo manifest for proper disposal. Hazardous cargo manifests include the same information as is on the Material Safety Data Sheet (MSDS): material information, exposure situations, hazard prevention & protection and other specific information. These dictate the proper handling and disposal procedures for all striping materials.

MUNI - 46





Goal: Flush sprayer paint supply lines at the corporation yard. Use approved collection methods and dispose of recycled waste materials at an appropriate waste facility.



Spray paint supply lines are cleaned at the corporation’s yard into a 55-gallon drum which, when full, is consigned to a hazardous waste hauler for disposal.


Goal: To the maximum extent practicable, clean sprayers and patch paving equipment at the end of the day. Use approved collection methods and dispose or recycle waste materials at an approved facility.



Sprayers and patch paving equipment is cleaned at the end of each shift. Contaminated cleaning fluids are captured in a 55-gallon drum at the corporation yard. When full, the drum is consigned to a hazardous waste hauler for transportation, documentation, and disposal.


Goal: Cover sprayers, patch and paving equipment to prevent rainfall from contacting pollutants (examples of cover include, but are not limited to, tarps, overhangs or inside of buildings).



Sprayers and paving equipment are covered if there is a possibility of rainwater contacting contaminated surfaces.


Goal: Assign one person the primary responsibility for coordinating implementation of BMPs. This person will also be responsible for ensuring that all individuals using the facility are aware of BMPs.

MUNI - 47






The Stormwater Program Manager, Jeff Roubal, is assigned primary responsibility for coordinating implementation of Best Management Practices (BMP). Attachment MN-43 to Concord’s FY 2005-06 Annual Report outlines Jeff's responsibilities in training, education, and monitoring BMP. Jeff is responsible for ensuring that all the individuals using City facilities are aware of the appropriate BMP.


Goal: Prepare spill containment kits and store them in locations that have potential for spills (fueling areas, etc.).



Spill containment kits are prepared and deployed to fueling areas, equipment maintenance areas, and paint mixing areas. In addition, street maintenance crews and custodial staff have mobile spill kits to respond to spills in the field.


Goal: Stencil/mark inlets to the storm drainage system within the facility with a message such as “No Dumping, Drains to Bay.”



All storm City of Concord drain inlets are stenciled with "No Dumping- Drains to Bay."

Almost 80% of the 600 Concord residents surveyed in this year's city-wide survey knew about the blue fish stenciled on each catch basin to prevent stormwater pollution.


Goal: Refer to existing plans (e.g., Hazardous Materials Business Plans and/or Spill Prevention Control and Countermeasures Plan), incorporate stormwater BMPs in any updates, and periodically review with persons using the facility.


MUNI - 48






The City of Concord Stormwater Pollution Prevention Plan was updated in Fiscal Year 2004-05 to include all the new facilities, equipment, personnel, and procedures. During the course of the rewrite, persons from every section contributed ideas and suggestions. A copy of the Stormwater Pollution Prevention Plan can be found at Attachment MN-25 to Concord’s FY 2005-06 Annual Report.


Goal: Conduct a facility inspection annually.



The facility Manager conducted inspections of every City of Concord facility at least annually. The purpose is to ensure these facilities and infrastructures are maintained in a manner that will maximize the usefulness and cost effectiveness of these facilities in enhancing the quality of life of employees, citizens, and visitors.

All major or critical equipment (e.g. chillers, boilers, air handlers and associated controls, air compressors, etc.) was on a preventive maintenance schedule. Manufacturer's recommendations and local craft expertise and site specific conditions determine the frequency of preventive maintenance procedures. All minor or non critical equipment (e.g. restroom exhaust fans, domestic hot water circulating pumps, automatic door operators, temperature control devices, etc.) were lubricated, cleaned and checked for proper operating condition at least annually.

As part of the annual inspections, facilities personnel look for possible stormwater exposure to pollutants, e.g. drips, leaks


Goal: Prepare a Storm Water Pollution Prevention Plan (SWPPP) for each maintenance facility.


Date Started: 07/01/2006 Date Complete: 12/31/2007 Status: Not Complete

The City of Concord Stormwater Pollution Prevention Plan was updated in September 2004. There is a copy of the Corporation Yard Stormwater Pollution Prevention Plan at Attachment MN-25 to Concord’s FY 2005-06 Annual Report.

MUNI - 49




Goal: Develop and post BMPs for other public agencies that use the corporation yard.



The only agency that uses the corporation yard is the City of Concord.


Goal: Distribute educational materials and post them in appropriate areas.



Stormwater pollution prevention education materials are available on racks in the City Manager's Office, the One-stop Permit Center, the Finance Cashier's office, Public Works-Engineering Services, Public Works-Maintenance Services, the Police Department lobby, and the Concord Public Library.


Goal: Clean all vehicles and equipment on designated wash pad areas.



The City has a wash area at the corporation yard. It is a drive-through facility covered with a roof and walls on two sides. The floor is a concrete pad sloped to flow to a center drain plumbed to the sanitary sewer. The City also contracts with several commercial car wash facilities to wash sedans, police vehicles, and small pick-up trucks. There is a picture of a vehicle being washed at the wash rack in Attachment MN-24 to Concord’s FY 2005-06 Annual Report.

Concord also has a contract with Brothers Detail Center, 1840 Monument Boulevard, to wash city vehicles.


Goal: Monitor wash pad areas to make sure they are consistently used.

MUNI - 50






The wash area is adjacent to Concord's garage and equipment repair facility. Vehicle maintenance personnel monitor the wash pad area to make sure it is consistently used for washing vehicles and equipment.


Goal: Wash vehicles and equipment, whether on-site or off-site, so wash water drains to the sanitary sewer or is recycled. Ensure the on-site wash pad area and sumps are large enough so that all wash water drains to the sanitary sewer or recycling system. Re-grade the area, if necessary, or install dikes to control wash water.



City personnel used wash area at the corporation yard. It is a drive-through facility covered with a roof and walls on two sides. The floor is a concrete pad sloped to flow to a center drain plumbed to the sanitary sewer. The facility is large enough to accommodate the biggest equipment in the City inventory.

The City also contracted with commercial car wash facilities to wash sedans, police vehicles, and small pick-up trucks. These commercial facilities recycled their wash water.


Goal: A plan for the storage, use and disposal of hazardous materials will be developed and implemented to insure these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management.



Concord safety guidance for the storage, use and disposal of hazardous materials was developed and implemented to insure these materials don't enter the storm drain system. The plan includes employee training and spills management. A copy of the chapter on hazardous materials is included at Attachment MN-44 to Concord’s FY 2005-06 Annual Report. Administrative Directive 99, Hazardous Substances Handling, is at Attachment MN-45 to Concord’s FY 2005-06 Annual Report.

MUNI - 51





Goal: Store spill containment kits nearby. If spills occur, use dry methods to sweep the fueling area and follow procedures (e.g., the Hazardous Materials Business Plan (HMBP) and/or Spill Prevention Control and Countermeasure Plan).



Spill containment kits are prepared and deployed to areas most likely to experience a spill:

Fueling areas; Equipment maintenance areas; and Paint mixing areas.

In addition, street maintenance crews and custodial staff have spill kits to respond to spills in the field. If spills occur, staff uses dry methods to absorb the liquid then collect the contaminated absorbent material for proper disposal.


Goal: Train employees in proper fueling and sweeping procedures.



New employees are trained, as part of their orientation, on the proper operation of fuel pumps and what to do in case of a spill. Sweeping procedures for proper clean up of spills are contained in biweekly tailgate safety meetings that are attended by all employees.


Goal: Do not conduct fueling over open ground. The ground should be covered by concrete or asphalt protected with a sealant.



Fueling was never done over open ground.

MUNI - 52





Goal: Install signs reminding people not to “top off” tanks.



Both of the City of concord fueling areas, the Corporation Yard and the Police Department, have large signs reading "Do Not Top Off" over the fuel pumps. Attachment MN-90 to Concord’s FY 2005-06 Annual Report shows a sign on the fuel pump saying “Do Not Top Off”


Goal: Discourage mobile fueling. If equipment is fueled with a mobile fuel truck, establish designated areas for fueling.



Equipment was not fueled with a mobile truck..


Goal: Investigate covering existing liquid fuel dispensing areas and implement if financially feasible.



The fueling area at the Concord Police Department is covered. The fueling area at the Corporation Yard will be covered when funds become available.


Goal: Design new fueling areas to limit to the maximum extent practicable “run-on” of stormwater and runoff of spills.



Fueling areas were designed to prevent run-on of stormwater and runoff of spills.

MUNI - 53






Goal: Store paint and other chemicals in an approved covered containment area. Design the floor inside so that any spilled materials will be contained and easily removed. Keep all containers with hazardous materials or waste closed when not filling or emptying. Label the outside according to Department of Transportation regulations. Protect the area from vandalism.



Paint and other chemicals were stored in a special containment area. The area was designed to contain any spilled materials. All containers were kept closed when not filling or emptying material. The outside of each container and the outside of the containment area was labeled according to Department of Transportation regulations. The area was secured from vandalism.


Goal: If containers with hazardous materials or wastes are stored outside, keep containers in an approved containment area. Ensure all of the containers are closed with tight-fitting lids.



Containers with hazardous wastes are stored indoors or under cover in a designated containment area. All containers are closed with tight-fitting lids.


Goal: Annually review agency’s plan for hazardous materials storage requirements.



City of Concord Administrative Directive 99 requires that staff review the plan for hazardous materials storage annually. A copy of Administrative Directive 99 can be found in Attachment MN-45 to Concord’s FY 2005-06 Annual Report.

MUNI - 54





Goal: Review Material Safety Data Sheets so incompatible materials have appropriate separation.



Storage of hazardous materials was done in accordance with Materials Safety Data Sheets. Incompatible or reactive materials were stored with at least minimum separation distances prescribed in the MSDS.


Goal: Keep necessary safety equipment and spill containment kits readily accessible in areas where chemicals are used. Inspect safety equipment regularly so that they are operational.



Safety equipment and spill containment kits are prepared and deployed to areas most likely to experience a spill:

Fueling areas; Equipment maintenance areas; and Paint mixing areas.

In addition, Public Works maintenance crews and custodial staff have spill kits to respond to spills in the field. Staff inspects kits regularly for completeness and serviceability.


Goal: Review Material Safety Data Sheets.



Materials Safety Data Sheets are reviewed each time a new material is received. In addition, sheets are reviewed each time there is a change in personnel. Also MSDS are reviewed during employee biweekly tailgate safety meetings.

MUNI - 55





Goal: Minimize the use of chemicals. Use water-based paints and non-toxic chemicals as much as possible.



Hazardous chemicals are used only where non-toxic alternative exists. The clear preference is for environmentally friendly products, e.g. biodegradable, water-based, and non-toxic.


Goal: Dispose of excess chemicals at an appropriate disposal location or recycle the chemical.



Excess chemicals were disposed of at the Household Hazardous Waste Disposal site, 4797 Imhoff Place, Martinez. The HHW Collection Facility was jointly sponsored by Central Contra Costa Sanitary District (CCCSD) and the City of Concord to help prevent pollution to our water environment by providing quick and easy disposal and recycling of HHW. HHW consists of substances that can poison, corrode, explode, or ignite when handled improperly. They can threaten public health and the environment. It is illegal to dispose of these substances in the trash, on the ground, down household drains or storm drains.

Examples of HHW accepted at the facility include: household cleaning products, mercury (thermometers, fluorescent bulbs), used motor oil, batteries, brake and transmission fluids, antifreeze, solvents, oil-based and latex paint, wood stain, paint remover, pesticides, herbicides and aerosol cans. Attachment 265 is a Certificate of Recycling for mercury bulbs from the City of Concord


Goal: Wipe oil based paint out of brushes. Filter and reuse thinners. A plan for the storage, use and disposal of hazardous materials will be developed and implemented so that these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management.


MUNI - 56





City of Concord staff uses the Best Management Practices in cleaning paint brushes and using paint thinners. Brushes are wiped of oil based paint. Thinners are reused as many times as possible. These practices save money and protect the environment.


Goal: Rinse latex paint out of brushes and discharge rinse water to the sanitary sewer. Dry excess paint in cans and dispose of the cans in the trash. A plan for the storage, use and disposal of hazardous materials will be developed and implemented to insure these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management.



City of Concord staff uses the Best Management Practices in cleaning paint brushes. Latex paint is rinsed from paintbrushes in a work sink that drains to the sanitary sewer. Empty paint cans are dried in the sun so that all the paint hardens before they are discarded to the trash. The City of Concord Stormwater Pollution Prevention Plan can be found at Attachment MN-25 to Concord’s FY 2005-06 Annual Report.


Goal: Collect used automobile fluids and dispose of them at an appropriate facility or recycle them. A plan for the storage, use and disposal of hazardous materials will be developed and implemented to insure these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management.



Oil and hydraulic fluids were collected separately and picked up by a recycling company who refines and sells recycled products. Oil and hydraulic fluid were never allowed to enter the storm drain.


Goal: Properly dispose of or recycle used solvents/chemicals. A plan for the storage, use and disposal of hazardous materials will be developed and implemented to insure these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management.

MUNI - 57





Used solvents and chemicals were collected at the City of Concord Corporation Yard in 55-gallon drums. When the drums were full, a special waste hauler took them on a hazardous waste manifest for proper disposal.


Goal: Inspect equipment for leaks on a regular basis. Use drip pans under leaky vehicles. Repair vehicles with significant leaks.



Certified mechanics checks all City of Concord vehicles for oil, fluid, or hydraulic leaks at least twice a year. Mechanics performed 530 inspections for mechanical fluid leaks.

380 Preventative Maintenance inspections of general purpose vehicles 39 Preventative Maintenance inspections of heavy duty vehicles 459 Preventative Maintenance inspections of police vehicles

The City of Concord's Fleet Management Division is certified as a Green Business by the Association of Bay Area Governments (ABAG). Businesses must be re-certified every three years. The Fleet Management Division was initially certified as a Green Business in February 2003 and has again successfully demonstrated full compliance with environmental regulatory agencies and has taken action to conserve resources and protect the environment. The following areas were examined by representatives from the Contra Costa Water District, Central Contra Costa Sanitary District, and the Contra Costa Health Services Hazardous Materials Division to determine if the Fleet Management Division met the criteria to be a certified Green Business:

Adherence to all regulations Reduction in the generation of waste products Recycling and reuse of materials Use of recycled materials Energy conservation Water conservation Pollution prevention Vehicle and equipment preventive maintenance practices

The Bay Area Green Business Program recognizes public agencies that are doing their part to save the environment in the San Francisco Bay Area. Six counties, Alameda,

MUNI - 58



Contra Costa, Marin, San Francisco, Santa Clara, and Sonoma, participate in the program, which certifies businesses that go beyond environmental compliance rules and complete voluntary measures to conserve energy and water, reduce waste and pollution, and increase recycling.

To be certified as "green," organizations must bring their operations into compliance with all environmental regulations and then go beyond that to meet the Green Business Standards. Staff from participating government regulatory agencies inspects the businesses, which are then required to:

Monitor and record rates of water and energy usage Monitor solid and hazardous waste generation Provide three ongoing incentives or training opportunities to encourage

employee participation in the program Inform customers about efforts to meet the standards Refer at least one other business to the Green Business Program.


Goal: Drain and replace motor oil and other fluids in a covered shop area. If fluids are changed outdoors, designate an area where there are no connections to storm drains or the sanitary sewer and where spills can be easily swept up.



Motor oil is changed every six months in general purpose vehicles and more often in special purpose vehicles. All work is done indoors in the City garage at 2360 Bisso Lane. The garage has a concrete floor that is elevated above grade to prevent run-on of stormwater. The shop floor has no connections to the sanitary sewer or storm sewer systems.


Goal: Periodically dry sweep the area.



The garage is swept daily or more often if needed. Absorbent material is used to prevent liquids from being tracked from one area to another. Absorbent material contaminated with automotive fluid is collected for disposal as hazardous waste.

MUNI - 59




Goal: Inspect the yard routinely to ensure there are no illegal discharges to the storm drain system. During storms, pollutant discharges will be controlled to the maximum extent practicable.



Personnel inspected the City of Concord Corporation Yard daily to spot any illegal discharges to the storm drain system. During rainstorms, contaminated equipment was covered and supplies are brought indoors to prevent rainwater from contacting with possible pollutants.


Goal: Sweep the paved portion of the corporation yard(s). Dispose of material removed from streets and storm drainage facilities regularly to eliminate exposure to rainwater and runoff to the storm drain system.



The entire corporation yard was paved with asphalt or concrete. The pavement was swept once a week with Tymco regenerative air vacuum sweepers.

Material removed from the streets during sweeping operations was disposed of the same day. Material was picked up once or twice a day (depending on the season) by Concord Disposal Services. Material vacuumed from storm drains was also disposed of the same day.


Goal: Consider alternatives for pesticide/herbicide control including: No controls, Physical/mechanical controls (hand labor, and county work furlough crews, etc.), Alternative vegetation controls (mulching, prescribed burns, etc.), Biological controls (predators, parasites, goats, etc.), Less toxic chemical controls (e.g., soaps and oils), and/or Hot water.



MUNI - 60




Concord continued to be environmentally sensitive to the hazards of the indiscriminate use of herbicides and pesticides and pesticide’s effect on the water quality of the surrounding waterways. When pesticides had to be used, Concord’s state certified specialists used the most environmentally safe chemicals available to the maximum extent practicable.

City of Concord's municipal herbicide and pesticide programs used short-term pre-emergent herbicides, spot spraying and hand labor to control weeds. Concord used an Integrated Pest Management system in all 31 City parks, street medians, and rights- of way. Although the area maintained had increased steadily over the last several years, with the addition of several landscaped street medians and roadsides, the use of pesticides had not.

In lieu of herbicide spraying, staff placed wood chip mulch made from tree prunings for weed control. This method had been found to be effective. It was being used on the creeks in Newhall, Brazil Quarry, and Concord Nature Parks and will be extended to Hillcrest Park next year.

Before using any insecticide, staff looks to see if a biological control (a natural predator) was on site. If it was, no treatment was done and the site was monitored. Staff had also been effective in injecting pesticide into the soil around selective trees. The trees absorb the insecticide through its roots. This method was proving to be effective for spot control of insects.

In pest management operations, the City of Concord treated all pesticides as though they were potentially hazardous to human and environmental health. Staff gave preference to reasonably available non-pesticide alternatives when considering the use of pesticides on City property. Staff maintained an active IPM plan for long-term prevention or suppression of pest problems with minimal impact on human health, non-target organisms, and the environment. For pest problems on City property, staff followed Standard Operating Procedures (SOP’s) of our IPM Policy (Attachment 261) designed to meet the requirements of the mandated National Pollutant Discharge Elimination System (NPDES) permit.

Over the past ten years, Concord had not increased the amount of chemicals used while the area covered had increased with the addition of new parks, street medians and open space. Currently, whenever possible, instead of spraying, we use beneficial insects or insecticidal soap. Applicators use a more scientifically developed approach and more sophisticated equipment such as a spray truck with an injection control system, a component of which was a radar speed sensor. With this equipment, the amount of pesticides and herbicides used was preset and measured exactly. This process eliminates any potential for chemical overuse and waste. This equipment was used for spraying pesticides and herbicides on median landscapes, open spaces, and parks.

MUNI - 61

The State of California certifies all of our pesticide applicators and supervisors.


Goal: Use the most effective, least toxic pesticides. Take into consideration the LD50, overall risk to the applicator and impact to the environment.



The City of Concord only uses pesticides as a last resort. If pesticides are necessary, staff only uses pesticides with a "Caution" label -- the least toxic kind.


Goal: Comply with all appropriate federal, state and local laws and regulations including the following directives: Federal: U.S. EPA Air and Toxics Division, Pesticides, State: Cal-EPA Department of Pesticide Regulation, and Local: Contra Costa County Agricultural Commissioner.



The City of Concord complies with all Federal, State, County, and Local laws and regulation for the application of pesticides. Licensed and certified pesticide application specialists undergo constant training in the latest government regulations as a part of their ongoing licensing and certification process.


Goal: Appropriate agency personnel will read and follow label instructions.



All City of Concord personnel read and follow label instructions, particularly licensed and certified pesticide applicators. There is a mandated system of checks and double checks so that each pesticide application is reviewed by multiple trained experts.

MUNI - 62





Goal: Encourage applicators to attend meetings and other professional avenues for continuing education (e.g., U.C. Cooperative Extension classes, Pesticide Applicator Professional Association).



Every pesticide applicator is required to complete thirty hours of continuing education every two years. This training is tracked and recorded by the State of California, Department of Pesticide Regulation.


Goal: Contact the U.C. Statewide IPM Project, the U.C. Cooperative Extension Office as well as private consulting firms, and libraries for information on integrated pest management, as appropriate.



Concord licensed and certified pesticide applicators consult with private firms, the Contra Costa County Agriculture Advisor, professional associations like PAPA - Pesticide Applicators Professional Association, as well as the Contra Costa County Master Gardener's research library and local reference materials.


Goal: Use state-certified pesticide applicators.



The City of Concord only hires pesticide applicators licensed and certified by the State of California.


Goal: Apply pesticides at the appropriate time to maximize their effectiveness and minimize the likelihood of discharging non-degraded pesticides in stormwater runoff.


MUNI - 63






Each pesticide application was carefully timed to have the maximum effect on the target organism and the minimum environment impact. Pesticides were never applied during windy or inclement weather. Pesticides were always applied in accordance with label instructions and manufacturer's recommendations.

The City of Concord partnered with other public agencies and local merchants to offer point-of-sale literature for shoppers at Ace Hardware, Navlet’s Nursery and Garden Center, Orchard Supply hardware, and Yardbirds. The literature described Integrated Pest Management techniques for home gardeners to reduce the use of pesticides and chemical fertilizers. Attachment PE-185 shows a copy of a flyer describing the program.

The City of Concord advertised and supported California’s Invasive Weeds Awareness program. Attachment 190 to Concord’s FY 2005-06 Annual Report has a copy of the campaign flyer.

Concord staff also partners with other Public Works agencies throughout the Bay Area to develop and disseminate best management practices through the American Public Works Association. There are examples of APWA monthly newsletters at Attachments 256 and 257.


Goal: Do not mix or load pesticides adjacent to a storm drain inlet, culvert or watercourse.



Pesticides were mixed in a special area of the City Corporation Yard designed to contain spills. Any spills were immediately picked up with a rag or absorbent material. Pesticides were never mixed near storm drains, culverts or watercourses.


Goal: Select pesticides and application techniques along road sides that will retain some vegetative cover to help prevent soil erosion, trap pollutants and slow the rate of stormwater runoff, where possible.



MUNI - 64



Pesticides were not used in roadside ditches. City crews hand-removed vegetation from roadside ditches. In addition to reducing the amount of pesticide used overall, this helped prevent erosion of the roadside ditches.


Goal: Select pesticides and application techniques along road sides that will retain some vegetative cover to help prevent soil erosion, trap pollutants and slow the rate of stormwater runoff, where possible.



Pesticides were not used in roadside ditches. City crews hand-removed vegetation from roadside ditches. In addition to reducing the amount of pesticide used overall, this helped prevent erosion of the roadside ditches.


Goal: Calibrate field equipment prior to use to ensure desired application rate. Mix only as much material as necessary for treatment.



Each application is described well ahead of time in a written Pest Control Advisor (PCA) recommendation. The recommendation contains instructions on exactly how much material to mix. In this way, only the exact amount of pesticide needed for each application is mixed. A copy of each PCA recommendation is sent to the Contra Costa County Agricultural Advisor.


Goal: Follow all legal requirements for Pesticide Management Zones (defined as areas where specific pesticide residues have been detected in groundwater) in Section 6800, Title 3 of the California Code of Regulations.



MUNI - 65




Concord has two Pesticide Management Zones identified in Section, Title 3 of the California Code of Regulations. No pesticides were applied in these zones in Fiscal Year 2005-06. Attachment MN-46 to Concord’s FY 2005-06 Annual Report defines these two zones and the associated pesticide restrictions.


Goal: Train applicators in the safe use of pesticides and proper inspection of applicator equipment to prevent accidental pesticide leaks, spills and hazards to applicators and the environment.



Applicators receive initial and refresher training in the safe use of pesticides and proper inspection and operation of applicator equipment.


Goal: If changing pesticides or cleaning spray tanks, use tank rinse water as product over a targeted area within the application site.



Tank rinse water is used as product over the target site in accordance with the PCA recommendation.


Goal: Maintain a record of all treatments including pesticide use for each site.



All pesticide applications are meticulously recorded. Copies are kept with the City of Concord Pesticide Control Advisor and the Contra Costa County Agricultural Advisor. The records are audited annually by the State of California for completeness and accuracy.

MUNI - 66





Goal: Reduce to the maximum extent practicable the use of algaecides containing copper as an active ingredient if discharges may ultimately reach watercourses or the San Francisco Bay-San Joaquin Delta.



Since Calendar Year 2004, the amount of algaecide containing copper used by the City of Concord in waters of the State has been reduced to zero. This voluntary non-use of copper algaecides has continued to the present day.

To prevent algae in Ellis Lake, City crews installed underwater bubblers. These bubblers accomplished four things:

eliminated cyanobacteria (blue-green algae) blooms; oxygenated lake bottom waters and sediments to prevent release of hydrogen

sulfide (the most common cause of complaints), iron, manganese, and phosphorus;

prevented seasonal fish kills; and reduced nuisance aquatic weed growth without either toxic chemicals or

fossil fuel consumption.

There are pictures of the new bubblers in action at Attachments MN-46, MN-47, and MN-48 to Concord’s FY 2005-06 Annual Report.


Goal: Reduce to the maximum extent practicable the use of copper-based pesticides. If applying copper as an algaecide, consider using a chelated form of copper for greater solubility (less settling to the bottom).



Prior to Calendar Year 2004, Concord used only the chelated form of copper as necessary to control algae growth in its lakes that discharge to waters of the State. Before it was used, staff would try to rake out the algae by hand. Concord used the staff of a commercial company, Aquatic Habitat, as a consultant to help decide the most environmentally effective method to control algae in our lakes. Staff planted vegetation at the site that inhibits the growth of the undesirable type of algae. In Calendar Year 2004, staff installed aerators to increase the oxygen content of the water in Ellis Lake and discontinued the use of algaecides containing copper.

The City of Concord partnered with Central Contra Costa Sanitary District to offer a series of six workshops in "Healthy Gardening." These workshops were open to the public and free of charge. The Central Contra Costa Sanitary District web site at http://www.centralsan.org/education/ipm/hgonlineguide.html has more information on Store partnerships, lawn care, physical controls cultural controls, beneficial insects, plant selection, roses, soaps & oils, ants aphids, snails & slugs, mosquitoes, yellow jackets spiders, safe use of pesticides, pest companies, and much more.


Goal: Reduce or eliminate the use of diazinon when a comparable product exists.



The City of Concord did not use diazinon.


Goal: Develop and implement a plan for the storage, use and disposal of hazardous materials so that these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management.



Attachment MN-25 to Concord’s FY 2005-06 Annual Report is a City of Concord pollution prevention plan that addresses storage, use and disposal of hazardous materials in a safe manner to avoid the possibility of stormwater pollution. The plan identifies potential sources of hazardous materials that could affect the quality of storm water discharged from the site. The plan also describes the best management practices to reduce or prevent pollutants in the storm water discharge.

Employees receive training about storm water pollution, and the relationship between shop activities and potential pollutants. This Awareness Training will be conducted with periodic brochures and flyers and backed up with periodic presentations on the subject by the NPDES Coordinator. New employees will be provided information during their orientation training.


Goal: Prepare spill kits, store the kits near pesticides, and train employees to use them.

MUNI - 70





Empty pesticide containers are rinsed to remove pesticide residue. Containers are disposed of in accordance with instructions for the California Department of Pesticide Regulation, the Contra Costa County Agricultural Commissioner and the manufacturer.


Goal: Attempt to find a qualified user for any unwanted pesticides, or return it to the manufacturer if unopened.



The City of Concord did not have any unwanted pesticides last year. If there had been some, staff would have returned them to the manufacturer or found another licensed, certified pesticide applicator to use them.


Goal: Develop and implement a plan for the storage, use and disposal of hazardous materials so that these materials are not allowed to enter the storm drain system. The plan will include employee training and spills management.



Golf course personnel have a plan that includes acquisition, storage, transportation, and use of hazardous materials on the golf course. Employees are regularly trained in proper handling of hazardous chemicals and what to do in the case of an accidental spill.


Goal: Avoid {fertilizer} applications if runoff is probable. On hillsides, avoid applying more water than the soil can absorb.



To conserve fertilizer, save money, and protect the environment, turf and landscape specialists at Diablo Creek Golf Course are very careful to not apply fertilizer to areas where runoff is probable. The goal is to maintain turf and landscaping with the absolute minimum amount of fertilizer required. To preserve their natural beauty, hillsides are not fertilized or irrigated.

MUNI - 71





Goal: Check irrigation equipment prior to applying fertilizer to determine if it is working properly. Monitor irrigation systems to avoid over watering.



Concord tests well and detention basin waters, soil and foliage at its golf course to help determine the appropriate amounts of fertilizer needed for applications. Approximately seventy-five percent of the golf course had been designed to drain to a detention basin. The basin was self-contained and had no outflow. The water in the detention basin was used to irrigate the golf course. Well water was used to keep the detention basin water at an acceptable level for irrigation.

During the hot summer months a form of chelated copper was used to control algae growth in the detention basin. A management plan that includes information on existing practices and fertilizer/pesticide use for the golf course was developed and implemented. The Contra Costa Clean Water Program is conducting a large, empirical study of organic fertilizers at a number of golf courses including Mount Diablo Golf Course.


Goal: Confine fertilizer to targeted area. If fertilizer has been applied to hardscape areas (e.g., roadways, walkways, paved surfaces), sweep, vacuum or blow back fertilizer from these areas before irrigating and/or rainfall. Do not wash down hardscape areas.



To conserve fertilizer, save money, and protect the environment, turf and landscape specialists at Diablo Creek Golf Course are very careful to not apply fertilizer to hardscaped areas. The goal is to maintain turf and landscaping with the absolute minimum amount of fertilizer required. Any fertilizer that fell on hardscaped areas by accident would be swept up.


Goal: Select fertilizers to complement local soil conditions, climate and plant health.



MUNI - 72




To conserve fertilizer, save money, and protect the environment, turf and landscape specialists in our Parks Division consider the time of year, plant species, weather, and anticipated usage before applying any products to the golf course. The goal is to maintain turf and landscaping with the absolute minimum amount of fertilizer required.


Goal: Fertilize plants based on plant type, physical appearance, soil or foliage testing.



Golf Course personnel consider the time of year, plant species, weather, and anticipated usage before applying any products to the golf course. The goal is to maintain turf and landscaping with the absolute minimum amount of fertilizer required.


Goal: If over-application is suspected, test soil and/or plant tissue for nutrients and trace elements as needed prior to applying fertilizer. If copper is not needed, eliminate it from the micronutrient blend.



If fertilizer over-application is suspected, specialists in Concord’s Parks Division conduct soil tests for nutrients and trace elements as needed prior to applying fertilizer. Micronutrient blends containing copper are not used.


Goal: Distribute educational materials promoting the implementation of Best Management Practices to municipal golf course operators.



As part of an educational effort to promote stormwater pollution prevention techniques and practices, Mount Diablo Golf Course joined a study to test effects of using of 100% organic fertilizer.

Mount Diablo Golf Course has an equipment washout area with an oil and grease separator that is plumbed to the Sanitary sewer. Periodic employee training ensures that everyone realizes the importance of washing equipment in this area. Attachment MN-50 to Concord’s FY 2005-06 Annual Report is a photograph showing the three stage separator and a golf course employee training to provide visual inspection of the separator for proper operation.


Goal: Test well water or other irrigation source water (e.g., nitrates) to help determine fertilizer requirements, as needed.



Well water is tested for a number of constituents that effect plant growth. Naturally occurring boron and salts affect the way that plants take up nutrients.


Goal: Test soil and foliage on greens and tees, as needed, to determine need for applications. If copper is not needed, the agency will eliminate it from the micro-nutrient blend.



Diablo Creek Golf Course personnel always test before applying any products to the golf course. The goal is to maintain turf and landscaping with the absolute minimum amount of fertilizer required.


Goal: Design golf courses to restore and/or maintain riparian areas/wetland and establish vegetation buffer zones along sensitive wetland areas to reduce runoff into waterways. Also, consider using detention ponds to control runoff and remove excess nutrients and/or divert excess irrigation water to areas where it can be used (e.g., roughs).



MUNI - 74




Mount Diablo Golf Course was designed to take advantage of its beautiful natural setting near Mount Diablo Creek. One of the features built into the course is tail water detention pond to capture and reuse surface water runoff.


Goal: Prepare a management plan which includes: 1) a comprehensive review of existing practices; and 2) a plan for fertilizer (and pesticide) use to minimize the amount needed and to control runoff.



Turf and landscape specialists at Diablo Creek Golf Course adhere to an annual maintenance plan when applying any products to the golf course. The goal is to maintain turf and landscaping with the absolute minimum amount of fertilizer required.

Fiscal Year 2007/2008 Goals:

In lieu of herbicide spraying, staff has been using wood chip mulch made from tree prunings for weed control. This method had been found to be effective on the creeks in Newhall, Brazil Quarry, and Concord Nature Parks. The practice will be extended to several more parks next year. Crews will complete a dry weather monitoring program earlier in the year in Fiscal Year 2007-08. The City of Concord will use a dry weather screening program to identify and address illicit discharges. The program will include outfall inspection and evaluation of any dry weather flows to determine if pollutants in non-stormwater flows are discharging into the drainage system. City staff will review the checklist used to conduct dry weather screening at selected outfalls. Dry weather flow is defined as any flow after 72 hours without a significant rain event. A significant rain event for this purpose is defined as over 0.1 inches of precipitation. Nine parameters are assessed if any dry weather flow is detected: Color, Odor, Clarity, Floating solids, Suspended solids, Oil/fuel sheen, Foam, Settled solids, and other obvious indicators of storm water pollution. Upon detection of a potential illicit discharge, City staff visually inspect upstream of the area in question to search for evidence indicating the source of the illicit discharge or illegal dumping. If the upstream search does not provide definitive evidence of the source, (e.g. staining, discoloration, unusual odors) the City will inspect storm sewer connections and convergences. City staff will work their way upstream until the source is located. The City may also elect to perform a stormwater site inspection at a facility suspected of having an illicit connection. A standard stormwater inspection checklist will be used during these site inspections. During inspection, dye testing may be performed to determine if there is an illegal tie-in. Potential illegal connections, such as floor drains, will be investigated as part of this inspection process. If an illicit source is identified, City Neighborhood Preservation staff will enforce the illicit discharge provision of the Concord Stormwater Ordinance. These regulations give the City the authority to require parties illegally discharging to the municipal stormwater system to remove the illicit connection as well as pay fines. The enforcement actions include a range of options from written warnings to fines up to $1,000. Following up on a very successful program, ten additional liter receptacles will be installed during FY 2007-08 in locations with high pedestrian traffic known to be prone to littering. This has proven to be one of the most effective ways to control litter in a defined area. Bus stops are ideal locations for litter receptacles. They are centrally located, concentrated pockets of pedestrian traffic.

MUNI - 76

Maintenance personnel will concentrate maximum effort on the fall leaf pick-up campaign. For approximately four to six weeks, depending on weather, all available staff will be dedicated to picking up what has historically been between 600,000 and a million pounds of leaves, in addition to the regular street sweeping program. Rapid, coordinated, and concentrated effort in this campaign keeps leaves out of the creeks, rivers, and delta.
