Introduction

SRF has completed a traffic study for the proposed Arbor Lake Business Park mixed-use development located in the southeast quadrant of the Elm Creek Boulevard/Zachary Lane intersection in Maple Grove, MN (see Figure 1: Project Location). The main objectives of this study are to review existing operations within the study area, evaluate development traffic impacts to the adjacent roadway network, including the proposed access and circulation, and recommend any necessary improvements to accommodate the proposed developments. This study will also include a long-term view (i.e. year 2040) of the area to ensure the proposed roadway network can accommodate additional area development. The following information provides the assumptions, analysis, and recommendations offered for consideration.

Existing Conditions

The existing conditions were reviewed to establish a baseline in order to identify any future impacts associated with the proposed development. The evaluation of existing conditions includes turning movement counts, field observations, and an intersection capacity analysis.

Data Collection

Weekday peak hour turning movement counts were provided by Hennepin County, which were collected as part of an area signal re-timing project in the spring of 2017 at the following study intersections:

a) Elm Creek Boulevard/Zachary Lane

b) Elm Creek Boulevard/Revere Lane

c) Elm Creek Boulevard/Jefferson Highway

d) Elm Creek Boulevard/US 169 West Ramps

e) Elm Creek Boulevard/US 169 East Ramps

August 11,2017 Arbor Lakes Business Park Traffic Study

Additional weekday a.m. and p.rn. peak hour counts were collected by SRF at the following intersections along Zachary Lane to identify area travel patterns and magnitude of volumes:

f) Fountains Way

g) Fountains Drive

h) North Lowe's Driveway

i) South Lowe's Driveway

Due to the high volume of heavy vehicles that utilize the study corridors, the heavy vehicle volumes were accounted for in the modeling efforts. In addition to the intersection turning movement counts and estimated average daily traffic volumes (obtained from the Minnesota Department of Transportation), observations were completed to identify roadway characteristics within the study area (i.e. roadway geometry, posted speed limits, and traffic controls). Elm Creek Boulevard is a minor arterial which is primarily a four-lane divided roadway immediately adjacent to the proposed development. The posted speed limit on Elm Creek Boulevard is 50 miles per hour (mph) between Zachary Lane and Revere Lane and 40 mph between Revere Lane and the US 169 Ramps. Zachary Lane is a four-lane divided roadway with select turn lanes and a 30 mph posted speed limit. The five study intersections along Elm Creek Boulevard are all signalized, while the four intersections along Zachary Lane are side-street stop control. Existing geometries, traffic controls, and volumes in the study area are shown in Figure 2.

Intersection Capacity Analysis

An existing intersection capacity analysis was completed for the weekday a.m. and p.m. peak hour to establish a baseline condition to which future traffic operations can be compared. The study intersections were analyzed using Synchro/SimTraffic (19). Capacity analysis results identify a Level of Service (LOS), which indicates the quality of traffic flow through an intersection. Intersections are given a ranking from LOS A through LOS F. The LOS results are based on average delay per vehicle, which correspond to the delay threshold values shown in Table 1. LOS A indicates the best traffic operation, with vehicles experiencing minimal delays. LOS F indicates an intersection where demand exceeds capacity, or a breakdown of traffic flow. Overall intersection LOS A through LOS D is generally considered acceptable in the City of Maple Grove.

August 11, 2017 Arbor Lakes Business Park T raffie Study

For side-street stop controlled intersections, special emphasis is given to providing an estimate for the level of service of the side-street approach. Traffic operations at an un signalized intersection with side-street stop control can be described in two ways. First, consideration is given to the overall intersection level of service. This takes into account the total number of vehicles entering the intersection and the capability of the intersection to support these volumes.

Second, it is important to consider the delay on the minor approach. Since the mainline does not have to stop, the majority of delay is attributed to the side-street approaches. It is typical of intersections with higher mainline traffic volumes to experience high levels of delay (i.e. poor levels of service) on the side-street approaches, but an acceptable overall intersection level of service during peak hour conditions.

Results of the existing intersection capacity analysis shown in Table 2 indicate that all study intersections currently operate at an acceptable overall LOS D or better during the a.m. and p.m. peak hours with the existing geometric layout and traffic controls. The study area is located adjacent to the existing Maple Grove Gravel Mining Area (GMA). Due to the high volume of heavy vehicles that utilize the study corridors, the heavy vehicle volumes were accounted for in the modeling efforts.

While all study intersection operate at an acceptable overall level of service, it should be noted that the eastbound left-tum 95th percentile queues at the Elm Creek Boulevard/US 169 East Ramps intersection extend to the Elm Creek Boulevard/US 169 West Ramps intersection during the p.m. peak hour. The northbound left-tum 95th percentile queue at this was observed extending to 250 feet due to the high volume of truck traffic making this maneuver. These queues are consistent with site observations within the study area. No other delay or queuing issues were identified.


August 11, 2017 Arbor Lakes Business Park Traffic Study

Proposed Development

The proposed Arbor Lakes Business Park development, shown in Figure 3, is located in the southeast quadrant of the Elm Creek Boulevard/Zachary Lane intersection. The proposed development is expected to include a mixture of uses, including warehousing, office, hotel, and restaurant type uses. For purposes of this study, the proposed development was assumed to be phased with Parcell completed by year 2025 and Parcels 2 and 3 completed by year 2040.

Parcell consists of four office warehouse buildings, totaling approximately 975,000 square feet. For purposes of this study, it was assumed that approximately 80 percent of the building space would be allocated to warehouse type use and 20 percent would be office type use. Based on conversations with City staff, Parcel 2 was assumed to include approximately 500,000 square feet of business park land use and a 6,000-square foot fast-casual or high turnover sit-down restaurant; Parcel 3 was assumed to include 575,000 square feet of general office and a 160-room hotel.

Access to the proposed development is assumed at the following locations:

a) Elm Creek Boulevard

o Full access between Zachary Lane and Revere Lane

b) Zachary Lane

o Full access approximately 450 feet south of Elm Creek Boulevard

o Full access at Fountains Drive

o Full access at the north Lowe's driveway

o Full access at the south Lowe's driveway

o Full access at the Lowe's loading dock driveway

c) Revere Lane

o Right-in/Right-out access approximately 250 feet south of Elm Creek Boulevard

o Full access approximately 450 feet and 650 feet south of Elm Creek Boulevard

o Full access at proposed extension of Fountains Drive

o Full access approximately 650 feet south of Fountains Drive

Additionally, three (3) new access points along the Service Road connecting Zachary Lane and Revere Lane would be constructed. Further discussion regarding site access is documented later in this study.

Year 2025 Conditions

To identify potential impacts associated with the proposed development of Parcell, traffic analysis for year 2025 conditions was completed. The year 2025 conditions take into account general area background growth, traffic generated by adjacent parcels, and traffic generated by the proposed development. 111e following sections provide details on the background traffic forecasts, estimated trip generation, and intersection capacity analysis for year 2025 conditions.

Background Traffic Growth

To account for general background growth and known adjacent developments in the area, an annual growth rate of one percent was applied to the existing through volumes on Elm Creek Boulevard to develop year 2025 background traffic forecasts. Background growth was not applied to peak hour trips entering/exiting the commercial development on Zachary Lane. This growth rate is consistent with historical traffic volume trends on Elm Creek Boulevard.

In addition to general background growth, trips generated from the Village at Arbor Lakes mixed-use development were also accounted for in the year 2025 traffic forecasts. This development, which is currently under construction, is expected to be fully constructed and operating under year 2025 conditions. Trip generation, routing, and directional distribution assumptions from the Village at Arbor Lakes Trcif.ftt' Sturjy, dated September 30, 2015 were utilized to estimate traffic volume impacts to the study intersections.

The proposed development is located within the Maple Grove GMA. Over the next 25 or more years, this area is planned to be redeveloped to include dense, compact, mixed-use type development. Current development proposals include Village at Arbor Lakes and the Arbor Lakes Business Park Traffic Study (proposed development). The tirneline for redevelopment of the remaining GMA is less known. To better understand how the proposed development will impact the adjacent roadway network, other areas of the GMA were not assumed to redevelop prior to year 2025. However, if additional areas within the Gi\lLA were to redevelop, additional review to traffic operations within the study area will likely be needed.

Trip Generation

To account for traffic impacts associated with the proposed development, trip generation estimates for the a.rn. and p.m. peak hours and on a daily basis were developed. These trip generation estimates, shown in Table 3, were developed using the lTE Trip Generation Manua~ Ninth Edition. Based on the proposed land use types, no multi-use, modal, or pass-by reductions were applied to the proposed development trips for Parcell. Results of the weekday trip generation estimates indicate the proposed development is expected to generate a total of approximately 539 a.m. peak hour, 539 p.m. peak hour and 4,928 daily trips.

Trips generated by the proposed development were distributed throughout the study area based on the directional distribution shown in Figure 4, which was developed based on existing travel patterns and engineering judgment. The resultant year 2025 traffic forecasts, which include general background growth, adjacent development trips and trips generated by the proposed development, are shown in Figure 5.

Year 2025 Intersection Capacity Analysis

To determine if the roadway network can accommodate the year 2025 traffic forecasts, a detailed intersection capacity analysis was completed using SynchrolSimTraffic software version 9.1. In addition to the study intersections, development driveways and internal intersections were analyzed to identify any site or access issues. It should be noted that the roadway geometry as shown on the proposed site plan (Figure 3) was used as the basis for this analysis, including a newly constructed four-lane cross section of Revere Lane.

Results of the year 2025 intersection capacity analysis shown in Table 4 indicate that all study intersections and proposed access locations are expected to operate at an acceptable overall LOS D or better during the a.rn. and p.m. peak hours with the existing roadway geometry and traffic controls and proposed access locations. However, the eastbound queues on Elm Creek Boulevard at the US 169 interchange are expected to extend from the US 169 East Ramps to west of Jefferson Highway. This is due to the large left-turn volume and a lack of appropriate turn lanes. Additional details regarding interchange operations and mitigations are discussed later in the document.

Year 2040 Conditions

To identify impacts associated with the development of Parcels 2 and 3 and potential future adjacent development within the GMA, traffic analysis for year 2040 conditions was completed. The goal of the year 2040 conditions review is to ensure that the segments of Elm Creek Boulevard, Zachary Lane, and Revere Lane are designed appropriately to accommodate the long-term needs and to minimize the potential for future impacts to the proposed development. The year 2040 conditions take into account general area background growth, traffic generated by the adjacent development within the GMA and the proposed development. The following sections provide details on the background traffic forecasts, estimated trip generation, and intersection capacity analysis for year 2040 conditions.

Background Traffic Growth

To account for general background growth in the area between year 2025 and year 2040 conditions, an annual growth rate of one-half percent was applied to the year 2025 background peak hour traffic volumes to develop year 2040 background traffic forecasts. The background growth rate between year 2025 and year 2040 is expected to be less than the background growth between existing and year 2025 conditions, due to the non-GMA area being closer to full-build out.

Adjacent Development Trip Generation

To account for traffic impacts associated with redevelopment with the GMA, traffic volume estimates were developed based on the future land use planned for the area. Future land use information was provided by City staff for the ongoing year 2040 Transportation Plan Update.

Since year 2040 traffic forecast information from the Twin Cities Regional Travel Demand Model was not available at the time of this study, trip generation estimates for the GMA were developed using the lIE Trip Generation Manual, Ninth Edition. These trips were distributed to the study intersections based on the directional distribution shown in Figure 4 and engineering judgment. It should be noted that besides the proposed development, the other redevelopment areas have not developed conceptual layouts indicating where access and parking will be proposed. Therefore, general assumptions were applied to estimate how vehicles would enter/exit the redevelopment sites.

Proposed Development Trip Generation

Parcels 2 and 3 of the proposed development are expected to be constructed and open between year 2025 and year 2040. Results of the trip generation estimates, shown in Table 5, indicate the proposed development including Parcell, 2, and 3 is expected to generate a total of approximately 2,286 a.m. peak hour, 2,181 p.m. peak hour and 19,560 daily trips. Trips generated by the proposed development were distributed throughout the study area based on the directional distribution shown in Figure 4. The resultant year 2040 traffic forecasts, which include general background growth, adjacent GJ\!IA development trips and trips generated by the proposed development, are shown in Figure 6.

Year 2040 Intersection Capacity Analysis

To determine if the existing roadway network, along with the proposed access locations, can accommodate the year 2040 build conditions traffic forecasts, a detailed intersection capacity analysis was completed using Synchroy'Sim'Fraffic software. Results of the year 2040 intersection capacity analysis, shown in Table 6, indicate there are areas of severe congestion within the study area, specifically intersections along Elm Creek Boulevard and the US 169 and Elm Creek Boulevard intersection. In addition to congestion noted along Elm Creek Boulevard, there were numerous access intersections along Zachary Lane and Revere Lane that are expected to experience congestion during the a.rn. and p.m. peak hours.

Year 2040 Recommended Improvements

To address the identified issues under year 2040 conditions and improve operations and safety, the following improvements, which are also shown in Figure 7, should be considered:

1) Based on the results of the year 2025 and year 2040 build conditions, an interchange modification will be necessary for the Elm Creek Boulevard and US 169 interchange. Modifications are currently being studied to determine the appropriate interchange configuration, including geometry and traffic control. Due to the interchange modification study, no recommendation will be provided as part of this traffic study. Once this modification report is completed, it will be included as an appendix item to this study,

2) Reconstruct Elm Creek Boulevard as a six-lane facility. This improvement is noted within the City of Maple Grove Transportation Plan and is recommended to be implemented.

3) Restripe to allow for the dual eastbound and westbound left-turn lanes at the Elm Creek Boulevard and Revere Lane intersection. Currently, the dual left-turn lane is hatched out, however, under year 2040 conditions it should be painted to allow for the dual turn.

Figure 7

01710758 July 2017



4) The Elm Creek Boulevard and Commerce Drive intersection could be mitigated with one of the following options:

a. Upgrade traffic control to a traffic signal (providing quarter spacing signal access along Elm Creek Boulevard, meeting City of Maple Grove Access Spacing Guidelines)

b. Restrict access to a right-in/ right-out. Note a three-quarter access was considered, but potential safety concerns are noted for eastbound and westbound left-turn movements crossing three uncontrolled through lanes.

c. Remove this intersection from the network, moving vehicular traffic to either Zachary Lane or Revere Lane.

5) Convert traffic control at the Revere Lane/Fountains Drive intersections to either an all-way stop control or a hybrid/multi-lane roundabout. A roundabout may provide more efficient traffic operations. Potentially modify the traffic control at the Zachary Lane/Fountains Drive intersection to a roundabout if access management to the north is implemented.

6) Due to significant side-street delays because of northbound Zachary Lane queuing, restrict access at the Zachary Lane/Costco and Parcell Central Access to a right-in/right-out on both the east and west side. Further access management along this roadway may be considered if a roundabout is constructed at the Zachary Lane/Fountains Drive intersection.

7) Update signal infrastructure and signal timing throughout the study area in conjunction with rising traffic volumes and striping of dual left -turn lanes.

8) Consider a consistent speed limit along Elm Creek Boulevard once additional access in constructed and utilized. Currently, speed limits along Elm Creek Boulevard vary from 40 mph to 50 mph throughout the corridor.

9) Consider removing the Interstate Service Road and closing Zachary Lane and Revere Lane with cul-de-sacs on their southern ends approaching 1-94. The Interstate Service Road serves a redundant route that is expected to be utilized by a minimal amount of traffic that can be diverted to other routes without major impacts to operations.

Year 2040 Intersection Capacity Analysis with Recommended Improvements

To determine if the recommended improvements to the existing roadway network, along with the proposed access locations are adequate to improve area traffic operations, a detailed intersection capacity analysis was completed using Synchro/SimTraffic software. Note, the US 169 interchange area was removed from the analysis and is being completed as part of a separate study. The Elm Creek Boulevard and Commerce Drive intersection was assumed to be upgraded to a traffic signal control and the Revere Lane and Fountains Drive were upgraded to an all-way stop control. .

Results of the year 2040 intersection capacity analysis with recommended improvements, shown in Table 7, indicate the recommended improvements allow for intersections to operate at an acceptable overall LOS D or better during the a.m. and p.m. peak hours. Access management (i.e. right-in/ right out) along Zachary Lane, specifically the intersection at Fountains Way may be necessary if delays and queuing become a severe issue.

Site Plan Review

A review of the proposed site plans was completed to identify any issues and recommend potential improvements with regard to site access, circulation, and parking. The follow improvements are offered for consideration, which are in addition to the improvements previously identified as part of the intersection capacity analysis. A summary of the recommended site plan improvements are shown in Figure 8, which correspond to the bullet labeling as follows:

a) General: Incorporate traffic controls, signing and striping based on guidelines established in the Manual on Uniform Traffic Control DeviceJ (MUTCD).

b) Install signing that restricts passenger vehicles from driving between the office/warehouse building loading areas.

c) Reduce shown access points to right-in/ right-out access.

d) Close the median to the parking aisle between the restaurant and office building to limit conflicts between entering/exiting vehicles and vehicles cutting through the restaurant parking lot.

e) Ensure all driveways connecting to the office/warehouse space allow for proper truck maneuverability.

£) Additional review of access points should be completed as Parcels 2 and 3 are further developed within the site plan to ensure safe and efficient operations.

g) Restripe the shared through-right-turn lane as a right-turn lane only as Fountains Drive is not a Four-Lane section to the west.

Summary and Conclusions The following study conclusions and recommendations are offered for your consideration:

1) Results of the existing intersection capacity analysis indicate that all study intersections currently operate at an acceptable overall LOS D or better during the a.m. and p.m. peak hours with the existing geometric layout and traffic controls.

a. The only location where queues currently extend beyond the available storage is the eastbound left-turn movement at the Elm Creek Boulevard/US 169 East Ramps intersection. The 95th percentile queues in this location extend to the Elm Creek Boulevard/US 169 West Ramps intersection during the p.m. peak hour.

2) The proposed Arbor Lakes Business Park development is located in the southeast quadrant of the Elm Creek Boulevard/Zachary Lane intersection.

a. The proposed development is expected to include a mixture of uses, including warehousing, office, hotel, and restaurant type uses.

b. For purposes of this study, the proposed development was assumed to be phased with Parcel 1 completed by year 2025 and Parcels 2 and 3 completed by year 2040.

3) Results of the trip generation estimates for Parcell indicate the proposed development is expected to generate a total of approximately 539 a.m. peak hour, 539 p.m. peak hour and 4,928 daily trips by year 2025.

4) To account for general background growth and known adjacent developments in the area, an annual growth rate of one percent was applied to the existing peak hour traffic volumes to develop year 2025 background traffic forecasts.

5) In addition to general background growth, trips generated from the Village at Arbor Lakes mixed use development were also accounted for the year 2025 traffic forecasts. This development, which is currently under construction, is expected to be fully constructed and operated under year 2025 conditions.

6) Results of the year 2025 intersection capacity analysis shown in Table 4 indicate that all study intersections and proposed access locations are expected to operate at an acceptable overall LOS D or better during the a.rn. and p.m. peak hours with the existing roadway geometry and traffic controls and proposed access locations.

a. The eastbound queuing at the US 169 interchange is expected to extend from the US 169 East Ramps to the west of Jefferson Highway. This is due to the large left-turn volume and a lack of appropriate turn lanes.

7) The year 2040 conditions take into account general area background growth, traffic generated by the proposed development Parcels 1,2, and 3, and adjacent development within the Gravel Mining Area.



8) Parcels 2 and 3 of the proposed development are expected to be constructed and open between year 2025 and year 2040. Results of the trip generation estimates indicate the proposed development including Parcel 1, 2, and 3 is expected to generate a total of approximately 2,286 a.m. peak hour, 2,181 p.m. peak hour and 19,560 daily trips.

9) To account for general background growth in the area between year 2025 and year 2040 conditions, an annual growth rate of one-half percent was applied to the year 2025 background peak hour traffic volumes to develop year 2040 background traffic forecasts.

a. The background growth rate between year 2025 and year 2040 is expected to be less than the background growth between exiting and year 2025 conditions, due to the non-GMA area being closer to full-build out.

10) To account for traffic impacts associated with redevelopment with the GMA, traffic volume estimates for the a.m. and p.m. peak hours and on a daily basis were developed based on the future land use planned for the area. Future land use information was provided by City staff for the ongoing year 2040 Transportation Pla.n Update. a. Since year 2040 traffic forecast information from the Twin Cities Regional Travel Demand

Model was not available at the time of this study, trip generation estimates for the GMA were developed using the lTE Trip Generation Manua~ Ninth Edition.

11) Results of the year 2040 intersection capacity analysis, shown in Table 6, indicate there are areas of severe congestion within the study area, specifically intersections along Elm Creek Boulevard and the US 169 and Elm Creek Boulevard intersection.

a. In addition to congestion noted along Elm Creek Boulevard, there were numerous access intersections along Zachary Lane and Revere Lane that are expected to experience congestion during the a.m. and p.m. peak hours.

12) To address the identified issues under year 2040 conditions and improve operations and safety, the following improvements, which are also shown in Figure 7, should be considered under long term conditions:

a) Based on the results of the year 2025 and year 2040 build conditions, an interchange modification may be necessary for the Elm Creek Boulevard and US 169 interchange. Modifications are currently being studied to determine the appropriate interchange configuration, including geometry and traffic control. Due to the interchange modification study, no recommendation will be provided as part of this traffic study. Once this modification report is completed, it will be included as an appendix item to this study.

b) Reconstruct Elm Creek Boulevard as a six-lane facility. This improvement is noted within the City of Maple Grove Transportation Plan and is recommended to be implemented.

c) Restripe to allow for the dual eastbound and westbound left-turn lanes at the Elm Creek Boulevard and Revere Lane intersection. Currently, the dual left-turn lane is hatched out, however, it should be painted to allow for the dual turn. Additionally, this will require a signal re-timing.

d) The Elm Creek Boulevard and Parcel 1 Central Access intersection could be mitigated with one of the following options:



I. Upgrade traffic control to a traffic signal (providing quarter spacing signal access along Elm Creek Boulevard)

II. Restrict this access to a right-in/ right-out access. Note, a three-quarter access was considered, but potential safety concerns are noted with crossing three uncontrolled through lanes.

III. Remove this intersection from the network, moving vehicular traffic to either Zachary Lane or Revere Lane.

e) Convert traffic control at the Revere Lane/Fountains Drive intersections to either an all-way stop control or a hybrid/multi-lane roundabout. A roundabout may provide more efficient traffic operations. Potentially modify the traffic control at the Zachary Lane/Fountains Drive intersection to a roundabout if access management to the north is implemented.

f) Due to significant side-street delays because of northbound Zachary Lane queuing, restrict access at the Zachary Lane/Costco and Parcell Central Access to a right-in/ right-out on both the east and west side. Further access management along this roadway may be considered if a roundabout is constructed at the Zachary Lane/Fountains Drive intersection.

g) Update signal infrastructure and signal timing throughout the study area in conjunction with rising traffic volumes and striping of dual left-turn lanes.

h) Consider a consistent speed limit along Elm Creek Boulevard once additional access in constructed and utilized. Currently, speed limits along Elm Creek Boulevard vary from 40 mph to 50 mph throughout the corridor.

i) Consider removing the Interstate Service Road and closing Zachary Lane and Revere Lane with cul-de-sacs on their southern ends approaching 1-94. The Interstate Service Road serves a redundant route that is expected to be utilized by a minimal amount of traffic that can be diverted to other routes without major impacts to operations.

13) A summary of the recommended site plan improvements are as follows:

a) General: Incorporate traffic controls, signing and striping based on guidelines established in the Manualon Uniform Trqific Control Devices (MUTCD).


c) Reduce shown access points to right-in/right-out access.

d) Close the median to the parking aisle between the restaurant and office building to limit conflicts between entering/ exiting vehicles and vehicles cutting through the restaurant parking lot.


£) Additional review of access points should be completed as Parcels 2 and 3 are further developed within the site plan to ensure safe and efficient operations.

SUBJECT: Arbor Lakes Business Park - PUD Concept and Development Stage Plan and Final Plat

After reviewing the above-mentioned submittal, the Park & Recreation Board staff has the following comments:

• The Park Dedication ordinance applies to this subdivision which requires a land dedication or a cash equivalent per unit based on the current rate.

• The applicant is purchasing land from the Tiller Corporation, they have requested the use of Park Dedication credits from the Tiller Corporation credit bank to satisfy the Park Dedication for this development. The balance is currently at 112.29acres.

• Tiller credit reduction calculates as follows:

112.29 available acres - 22.39 proposed acres = 89.9 remaining credit acres

• Arbor Lakes Business Park is located within PSA 24 which is the Gravel Mining Area, it currently has no developed park amenities. A Neighborhood Park is planned for this PSA in a location nearer to the proposed residential land use areas.

General • The recommendations above are that of the Parks and Recreation staff. Park dedication

requirements are acted on by the Parks and Recreation Board at their regularly scheduled monthly meetings and forwarded on to the City Council for final approval.

• Applicants may pay the park dedication fee at any time after the final plat has been approved by the City Council and Park Board but it must be paid before the plat is released by the City for filing.

• Park dedication rates are reviewed annually in February by the City Council. The rate is applied at the time the plat is released to the County for filing.

Marilyn Arnlund Friday, August 11, 2017 8:09 AM Dick Edwards; Peter Vickerman Arbor Lakes Business Park Site Plan comments

A fire department site plan review has been conducted for Building A for the Arbor Lakes Business Park. The fire department has the following comments:

1. Fire sprinkler water mains must be brought into a one-hour fire resistive room and must have exterior access, a drain, an emergency light pack, and a sidewalk to the public way. If the water main enters into a basement level the main may be extended to the first floor into a one-hour fire resistive room with the above requirements. Maple Grove City Code, Chapter 18, Article III, Fire Prevention Code, FPB-Policy 3.

Comments: It appears exterior access is provided, however it will need to be verified that the fire resistance, floor drain, and emergency light to the riser room are provided as well.

2. Fire Apparatus Access Roads: Approved fire apparatus access roads shall be provided for every facility, building, or portion of a building hereafter constructed or moved into or within the jurisdiction. The fire apparatus access road shall extend to within 150 feet of all portions of the facility or any portion of the exterior wall of the first story of the building as measured by an approved route around the exterior of the building.

Comments: Per our conversation on 8/10, it was agreed that the dead end located between the four buildings will be modified to allow emergency vehicle access directly through the site (north-south) as well as rearranging the driving and parking area between buildings B & D to accommodate a driving lane in the center.

3. Fire Apparatus Access Roads Design: Fire apparatus roads shall be designed to a 20 foot width and maintained to support the imposed loads of fire apparatus (7 ton) and shall be provided with a surface so as to provide all-weather driving capabilities. Longitudinal grade shall not exceed 6 percent or lateral grade shall not exceed 2 percent. Both grades shall not be used together. Fire apparatus access roads shall be a minimum of 30 feet and a maximum of 80 feet from buildings and shall be positioned parallel to the side of the building. A 20-foot inside and a 40-foot outside turning radius shall be provided for fire apparatus access and approved turnarounds. Maple Grove City Code, Chapter 18, Article III, Policy FPB-4

Comments: It appears that some of the turns do not meet turning radius requirements. Per our conversation on 8/10, it was agreed that all turns would be adjusted to better meet the turning requirement. It is also noted that the new fire trucks now have a 42 foot turning radius.

4. Location of Fire Hydrants and General Requirements: Hydrants shall be located within a reasonable distance from driving surface; five feet minimum from curb (fire department access). If hydrant is located in a safety island and cannot be located back five (5) feet from the curb, the hydrant shall be centered in the safety island. It is the fire department's preference to locate a fire hydrant along the

1

driveway entrance, unless only one fire hydrant is being installed and needs to be located closer to the fire department connection. NFP A 14, Section 3 -13.1

a. A fire hydrant shall be located within 150 feet of the fire department connection. NFPA 14, Section 6-3.5.4.

b. Hydrants and valves shall not be located closer than 40 feet from the building. NFP A 14, Section 3-13.2

c. If hydrants are located in front of parking spaces or roadways, a fire lane will be designated in front measuring 10 feet in each direction. MSFC, Section 503.3; Maple Grove City Code, Chapter 18, Article III, Policy FPB-l

d. Fire hydrants and other fire protection equipment must not be obstructed or the view of the equipment blocked. A minimum clearance of five (5) feet shall be provided and maintained aroundfire hydrants and other fire protection equipment. The full anticipated growth of the trees and shrubs must be considered when planting. A five (5) foot clearance must be provided when the landscaping reaches maturity. Any landscaping planted should be placed so it will meet the future clearance requirements at maturity. Maple Grove City Code, Chapter 18, Article III, Fire Prevention Code, Section 18-82.

Comments: Per our conversation on 8/10, it was agreed that two accessible hydrants would be added in the northwest and northeast corners of Building A. Also please verify the clearance of plantings around all fire hydrants.

Please feel free to contact me with any concerns or questions, Marilyn Arnlund
