2 Millwell Place/BPP15-0031

C. Findings for Consideration 1. Pierce Park Lane

a. Existing Conditions: Pierce Park Lane is improved with 2-travel lanes, bike lanes, extruded curb, and an asphalt pathway abutting the site. There is 54-feet of right-of-way for Pierce Park Lane (22-feet from centerline).

b. Policy: Collector Street Policy: District policy 7206.2.1 states that the developer is responsible for improving all collector frontages adjacent to the site or internal to the development as required below, regardless of whether access is taken to all of the adjacent streets.

Master Street Map and Typologies Policy: District policy 7206.5 states that if the collector street is designated with a typology on the Master Street Map, that typology shall be considered for the required street improvements. If there is no typology listed in the Master Street Map, then standard street sections shall serve as the default.

Street Section and Right-of-Way Policy: District policy 7206.5.2 states that the standard right-of-way width for collector streets shall typically be 50 to 70-feet, depending on the location and width of the sidewalk and the location and use of the roadway. The right-of-way width may be reduced, with District approval, if the sidewalk is located within an easement; in which case the District will require a minimum right-of-way width that extends 2-feet behind the back-of-curb on each side.

The standard street section shall be 46-feet (back-of-curb to back-of-curb). This width typically accommodates a single travel lane in each direction, a continuous center left-turn lane, and bike lanes.

Residential Collector Policy: District policy 7206.5.2 states that the standard street section for a collector in a residential area shall be 36-feet (back-of-curb to back-of-curb). The District will consider a 33-foot or 29-foot street section with written fire department approval and taking into consideration the needs of the adjacent land use, the projected volumes, the need for bicycle lanes, and on-street parking.

Sidewalk Policy: District policy 7206.5.6 requires a concrete sidewalks at least 5-feet wide to be constructed on both sides of all collector streets. A parkway strip at least 6-feet wide between the back-of-curb and street edge of the sidewalk is required to provide increased safety and protection of pedestrians. Consult the District's planter width policy if trees are to be placed within the parkway strip. Sidewalks constructed next to the back-of-curb shall be a minimum of 7-feet wide.

Detached sidewalks are encouraged and should be parallel to the adjacent roadway. Meandering sidewalks are discouraged.

A permanent right-of-way easement shall be provided if public sidewalks are placed outside of the dedicated right-of-way. The easement shall encompass the entire area between the rightof-way line and 2-feet behind the back edge of the sidewalk. Sidewalks shall either be located wholly within the public right-of-way or wholly within an easement.

ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM) guide the right-of-way acquisition, collector street requirements, and specific roadway features required through development. This segment of Pierce Park Lane is designated in the MSM as a Residential Collector with 2-lanes and on-street bike lanes, a 36-foot street section within 54-feet of right-of-way.

c. Applicant Proposal: The applicant is proposing to construct vertical curb, gutter, and a 7-foot wide attached concrete sidewalk on Pierce Park Lane abutting the site.


d. Staff Comments/Recommendations: The applicant's proposal meets District policy and should be approved, as proposed.

2. Saxton Avenue a. Existing Conditions: Saxton Avenue is improved with 2-travel lanes, and no curb, gutter or

sidewalk abutting the site. There is 40-feet of right-of-way for Saxton Avenue (20-feet from centerline).

b. Policy: Local Roadway Policy: District Policy 7207.2.1 states that the developer is responsible for improving all local street frontages adjacent to the site regardless of whether or not access is taken to all of the adjacent streets.

Street Section and Right-of-Way Policy: District Policy 7207.5 states that right-of-way widths for all local streets shall generally not be less than 50-feet wide and that the standard street section shall be 36-feet (back-of-curb to back-of-curb). The District will consider the utilization of a street width less than 36-feet with written fire department approval.

Standard Urban Local Street-36-foot to 33-foot Street Section and Right-of-way Policy: District Policy 7207.5.2 states that the standard street section shall be 36-feet (back-of-curb to back-of-curb) for developments with any buildable lot that is less than 1 acre in size. This street section shall include curb, gutter, and minimum 5-foot concrete sidewalks on both sides and shall typically be within 50-feet of right-of-way.

The District will also consider the utilization of a street width less than 36-feet with written fire department approval. Most often this width is a 33-foot street section (back-of-curb to backof-curb) for developments with any buildable lot that is less than 1 acre in size.

Off-Site Streets Policy: District Policy 7207.2.3 states that if the proposed development is not served by a public street with at least 24-feet of pavement then the developer shall pave the street or widen the existing pavement to provide 24-feet of pavement with 3-foot gravel shoulders from the site to a public street specified by the District.

Sidewalk Policy: District Policy 7207.5.7 states that five-foot wide concrete sidewalk is required on both sides of all local street, except those in rural developments with net densities of one dwelling unit per 1.0 acre or less, or in hillside conditions where there is no direct lot frontage, in which case a sidewalk shall be constructed along one side of the street. Some local jurisdictions may require wider sidewalks.

The sidewalk may be placed next to the back-of-curb. Where feasible , a parkway strip at least 8-feet wide between the back-of-curb and the street edge of the sidewalk is recommended to provide increased safety and protection of pedestrians and to allow for the planting of trees in accordance with the District's Tree Planting Policy. If no trees are to be planted in the parkway strip, the applicant may submit a request to the District, with justification, to reduce the width of the parkway strip.



Half Street Policy: District Policy 7207.2.2 required improvements shall consist of pavement widening to one-half the required width, including curb, gutter and concrete sidewalk (minimum 5-feet), plus 12-feet of additional pavement widening beyond the centerline established for the street to provide an adequate roadway surface, with the pavement


crowned at the ultimate centerline. A 3-foot wide gravel shoulder and a borrow ditch sized to accommodate the roadway storm runoff shall be constructed on the unimproved side.

c. Applicant Proposal: The applicant is proposing to construct Saxton Avenue as half of a 36-foot street section with rolled curb, gutter, and a 5-foot wide attached concrete sidewalk abutting the site. To accommodate these improvements, the applicant has proposed to dedicate an additional 5-foot of right-of-way to total 25-feet from the centerline to Saxton Avenue abutting the site.

d. Staff Comments/Recommendations: The applicant's proposal meets District policy and should be approved, as proposed. Consistent with ACHD's Off-Site Street policy, the applicant should be required to widen Saxton Avenue to 24-feet of pavement with 3-foot wide gravels shoulders between the proposed Portsmouth Way and Pierce Park Lane in areas where Saxton Avenue does not abut the site.

ACHD's Master Street Map identifies this section of Saxton Avenue as a residential collector roadway. The collector was anticipated to extend between Gary Lane and Pierce Park Lane, however, the alignment is on already existing streets with front on housing, and in subdivisions constructed without the stub streets necessary to make the public street connection between Gary Lane and Pierce Park Lane. Because of this staff recommends that Saxton between Gary Lane and Pierce Park Lane be reclassified as a local street and removed from the MSM.

The applicant has proposed to vacate the portion of Saxton Avenue west of the proposed Porthsmouth Way. This portion of Saxon Avenue is currently an unimproved right-of-way which stubs to an existing single family home in a developed subdivision. Staff is supportive of this proposal. The applicant should be required to apply to vacate the right-of-way when needed for the development of the site. The vacation is a separate application and approval process.

The Boise School District has indicated that they would like to see a walking path within the 100-foot wide drainage easement along the drain ditch located north of the site. The drain ditch is owned by Drainage District No. 2. Staff recommends that Boise City and the Boise School District work with Drainage District No. 2 to provide a pedestrian facility along the drainage ditch. ACHD does not own any rights-of-way in this location.

b. Policy: Local Roadway Policy: District Policy 7207.2.1 states that the developer is responsible for improving all local street frontages adjacent to the site regardless of whether or not access is taken to all of the adjacent streets.

Street Section and Right-of-Way Policy: District Policy 7207.5 states that right-of-way widths for all local streets shall generally not be less than 50-feet wide and that the standard street section shall be 36-feet (back-of-curb to back-of-curb). The District will consider the utilization of a street width less than 36-feet with written fire department approval.

Standard Urban Local Street-36-foot to 33-foot Street Section and Right-of-way Policy: District Policy 7207.5.2 states that the standard street section shall be 36-feet (back-of-curb to back-of-curb) for developments with any buildable lot that is less than 1 acre in size. This street section shall include curb, gutter, and minimum 5-foot concrete sidewalks on both sides and shall typically be within 50-feet of right-of-way.

The District will also consider the utilization of a street width less than 36-feet with written fire department approval. Most often this width is a 33-foot street section (back-of-curb to backof-curb) for developments with any buildable lot that is less than 1 acre in size.

Sidewalk Policy: District Policy 7207.5.7 states that five-foot wide concrete sidewalk is required on both sides of all local street, except those in rural developments with net densities of one dwelling unit per 1.0 acre or less, or in hillside conditions where there is no direct lot frontage, in which case a sidewalk shall be constructed along one side of the street. Some local jurisdictions may require wider sidewalks.

The sidewalk may be placed next to the back-of-curb. Where feasible, a parkway strip at least 8-feet wide between the back-of-curb and the street edge of the sidewalk is recommended to provide increased safety and protection of pedestrians and to allow for the planting of trees in accordance with the District's Tree Planting Policy. If no trees are to be planted in the parkway strip, the applicant may submit a request to the District, with justification, to reduce the width of the parkway strip.



Cul-de-sac Streets Policy: District policy 7207.5.8 requires cul-de-sacs to be constructed to provide a minimum turning radius of 45-feet; in rural areas or for temporary cul-de-sacs the emergency service providers may require a greater radius . Landscape and parking islands may be constructed in turnarounds if a minimum 29-foot street section is constructed around the island. The pavement width shall be sufficient to allow the turning around of a standard AASHTO SU design vehicle without backing. The developer shall provide written approval from the appropriate fire department for this design element.

The District will consider alternatives to the standard cul-de-sac turnaround on a case-by-case basis. This will be based on turning area, drainage, maintenance considerations and the written approval of the agency providing emergency fire service for the area where the development is located.

c. Applicant's Proposal: The applicant is proposing to construct all of the internal local streets as 36-foot streets with rolled curb, gutter, and 5-foot wide attached concrete sidewalks within


50-feet of right-of-way. The applicant is proposing to construct one cul-de-sac turnaround at the terminus of Porthsmouth Way.

d. Staff Comments/Recommendations: The applicant's proposal meets District policy and should be approved, as proposed. The cul-de-sac turnaround should provide a minimum radius of 45-feet.

4. Roadway Offsets a. Existing Conditions: There are no roadway offsets within the site.

b. Policy: Local Offset Policy: District policy 7206.4.5, requires local roadways to align or offset a minimum of 330-feet from a collector roadway (measured centerline to centerline).

District policy 7207.4.2, requires local roadways to align or provide a minimum offset of 125-feet from any other street (measured centerline to centerline).

c. Applicant's Proposal: The applicant has proposed to construct one roadway onto Pierce Park Lane, Watermill Drive, located approximately 125-south of the north property line (measured property line to centerline).

The applicant has proposed to construct one roadway on to Saxton Avenue, Watermill Drive, located approximately 500-feet west of Pierce Park Lane (measured centerline to centerline).

d. Staff Comments/Recommendations: The applicant's proposal to construct Millwater Drive to intersect Pierce Park Lane approximately 125-south of the north property line does not meet District policy, which requires local streets intersecting collectors to align or offset by 330-feet. Millwater Drive is proposed to offset Barron Lane by approximately 235-feet. However, staff recommends a modification of policy to allow Millwater Drive to be located as proposed. Staffs recommendation is due to the fact that the site does not have enough frontage to meet to the required offset. Staff 's recommendation is a 23% modification of policy and is approved at the Manager level.

All other roadways align or exceed the required offset of 125-feet, and should be approved, as proposed.

5. Tree Planters Tree Planter Policy: Tree Planter Policy: The District's Tree Planter Policy prohibits all trees in planters less than 8-feet in width without the installation of root barriers. Class II trees may be allowed in planters with a minimum width of 8-feet, and Class I and Class Ill trees may be allowed in planters with a minimum width of 10-feet.

6. Landscaping Landscaping Policy: A license agreement is required for all landscaping proposed within ACHD right-of-way or easement areas. Trees shall be located no closer than 10-feet from all public storm drain facilities. Landscaping should be designed to eliminate site obstructions in the vision triangle at intersections. District Policy 5104.3.1 requires a 40-foot vision triangle and a 3-foot height restriction on all landscaping located at an uncontrolled intersection and a 50-foot offset from stop signs. Landscape plans are required with the submittal of civil plans and must meet all District requirements prior to signature of the final plat and/or approval of the civil plans.
