Lead Agency: City of Meridian Site address: S. Black Cat Road Staff Approval: December 22, 2023 Applicant: Laren Bailey, via email Conger Group 4824 W Fairview Avenue Boise, ID 83706 Staff Contact: Dawn Battles, Senior Planner Phone: 387-6218 E-mail: dbattles@achdidaho.org A. Findings of Fact 1. Description of Application: The applicant is requesting approval of annexation with rezone from RUT (Rural-Urban Transition) to R-15 (Medium-High Density Residential) and a preliminary plat application to allow for the development of a 285 lot residential subdivision consisting of 246 buildable lots and 32 common lots on 34-acres. The applicant’s rezone proposal is consistent with the City of Meridian’s future land use map which designates this site as medium-high density residential. 2. Description of Adjacent Surrounding Area: Direction Land Use Zoning North Medium-High Density Residential, Rural-Urban Transition (Ada County), Limited Industrial (Ada County) & Community Commercial (Ada County) R-15, RUT, M1 & C2 South Rural-Urban Transition (Ada County) & Rural Residential (Ada County) RUT & RR East Medium-High Density Residential, Traditional Neighborhood- Center & Community Business R-15, TN-C & C-C West Light Industrial, Rural-Urban Transition (Ada County) & General Industrial (Ada County) I-L, RUT & M2 3. Site History: ACHD has not previously reviewed this site for a development application. 2 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 4. Adjacent Development: The following developments are pending or underway in the vicinity of the site: • Farmstone Crossing, a 6-lot subdivision that will consist of 270,880 square feet of industrial buildings, 85,120 square feet of office buildings and a 5,500 square foot convenience store/gas station on 28-acres located directly adjacent to the south and was approved by ACHD in October 2023. • Black Cat Industrial is located on the west side of Black Cat Road across from the site which encompasses 123-acres to allow for the development of a light industrial complex consisting of over 2 million square feet and an ACHD staff report for an annexation with rezone was issued in November 2021. • St. Luke’s Consolidation Service Center located within the Black Cat Industrial development, a proposed 280,000 square foot building on17-acres located on the west side of Black Cat Road across from the site and was approved by ACHD in March 2023. • Black Cat Business Center-Building J, located within the Black Cat Industrial development, a proposed 132,236 square foot building on 11-acres located on the west side of Black Cat Road and was approved by ACHD in March 2023. • Vanguard Village, a mixed use development consisting of 8 buildable lots and 6 common lots to allow for residential, commercial and office uses and 552 multi-family units on 115-acres located to the south and east of the site and was approved by ACHD in March 2022. 5. Transit: Transit services are available to serve this site, via Route 42. 6. Pathway Crossings: United States Access Board R304.5.1.2 Shared Use Paths. In shared use paths, the width of curb ramps runs and blended transitions shall be equal to the width of the shared use path. AASHTO's Guidelines for the Development of Bicycle Facilities 5.3.5 Other Intersection Treatments: The opening of a shared use path at the roadway should be at least the same width as the shared use path itself. If a curb ramp is provided, the ramp should be the full width of the path, not including any flared sides if utilized. . . . Detectable warnings should be placed across the full width of the ramp. FHWA's "Designing Sidewalks and Trails for Access" (1999) reflected common ADA-related concepts: Chapter 6, Page 16-6: The width of the ramp should be at least as wide as the average width of the trail to improve safety for users who will be traveling at various speeds. In addition, the overall width of the trail should be increased, so the curb ramp can be slightly offset to the side. The increased width reduces conflict at the intersection by providing more space for users at the bottom of the ramp. 7. Impact Fees: There will be an impact fee that is assessed and due prior to issuance of any building permits. The assessed impact fee will be based on the impact fee ordinance that is in effect at that time. The impact fee assessment will not be released until the civil plans are approved by ACHD. 8. Capital Improvements Plan (CIP)/ Integrated Five Year Work Plan (IFYWP): • Franklin Road is scheduled in the IFYWP to be widened to 5-lanes from McDermott Road to Black Cat Road with the design year in 2026 and the construction date has not been determined. • The intersection of Franklin Road and McDermott Road is scheduled in the IFYWP to be reconstructed as a single-lane expandable roundabout. There is no design year or construction year, and this project requires coordination with the Nampa Highway District. 3 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 • Black Cat Road is listed in the CIP to be widened to 5-lanes from Franklin Road to Overland Road between 2036 and 2040. Funding for ITD’s portion is not included with this project. 9. Roadways to Bikeways Master Plan: ACHD’s Roadways to Bikeways Master Plan (BMP) was adopted by the ACHD Commission in May of 2009 and was update in 2018. The plan seeks to implement the Planned Bicycle Network to support bicycling as a viable transportation option for Ada County residents with a wide range of ages and abilities, maintain bicycle routes in a state of good repair in order to ensure they are consistently available for use, promote awareness of existing bicycle routes and features and support encouragement programs and to facilitate coordination and cooperation among local jurisdictions in implementing the Roadways to Bikeways Plan recommendations. The BMP identifies Black Cat Road and Franklin Road, west of Black Cat Road as Level 3 facilities that will be constructed as part of a future ACHD project. The BMP also identifies existing Level 2 facilities on Franklin Road east of Black Cat Road. B. Traffic Findings for Consideration 1. Trip Generation (TIS required): This development is estimated to generate 3,136 vehicle trips per day; 286 vehicle trips per hour in the PM peak hour, based on the traffic impact analysis. 2. Traffic Impact Study Kimley Horn prepared an abbreviated traffic analysis (Attachment 3) for the proposed Avani Place subdivision. The analysis included site trip generation and distribution and a turn lane analysis. a. Staff Comments/Recommendations: Site Access and Turn Lanes 4 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 The traffic impact analysis indicates a southbound left-turn lane is warranted on Black Cat Road at Site Access A and a southbound right-turn lane is warranted on Black Cat Road at the intersection with Vanguard Drive (future east/west collector) under 2028 total traffic conditions. Although the analysis indicates a southbound left-turn lane is warranted on Black Cat Road at Site Access A, the applicant has revised the site plan and eliminated Site Access A to Black Cat Road; therefore, the turn lane is not required. The Black Cat Industrial site located on the west side of Black Cat Road across from the site and Farmstone Crossing located directly adjacent to the south are required to construct a center two-way left-turn lane on Black Cat Road when Vanguard Drive is constructed to intersect Black Cat Road. If the turn lane has not been constructed, then the applicant should be required to construct the center left-turn lane on Black Cat Road when Vanguard Drive is constructed to intersect Black Cat Road. 3. Condition of Area Roadways Traffic Count is based on Vehicles per hour (vph) * Acceptable level of service for a five-lane principal arterial is “E” (1,780 vph). * Acceptable level of service for a two-lane minor arterial is “E” (575 vph). 4. Average Daily Traffic Count (VDT) Average daily traffic counts are based on ACHD’s most current traffic counts. • The average daily traffic count for Franklin Road east of Umbria Hills Avenue was 16,011 on November 4, 2021. • The average daily traffic count for Black Cat Road south of Franklin Road was 5,046 on October 5, 2021. C. Findings for Consideration 1. Ten Mile Specific Area Plan (TMISAP) The transportation element of the TMISAP is to guide transportation decisions in the Ten Mile Interchange Area. It was developed concurrently with the Land Use and Design Elements and has been designed to preserve the integrity of the arterial road system and the Ten Mile interchange; provide for the use of public transit; enhance pedestrian and bicycle mobility and accessibility; and create transportation infrastructure and promote land use patterns that encourage the sustainable use of resources and reduces demands on natural resources. The TMISAP recommends the construction of an east/west collector roadway, Vanguard Drive, located along the site’s south property line. The applicant is proposing to construct their portion of the east/west collector roadway, shown in purple, located within the site at the site’s south property line. Roadway Frontage Functional Classification PM Peak Hour Traffic Count PM Peak Hour Level of Service Franklin Road None Principal Arterial 793 Better than “E” Black Cat Road 1,312-feet Minor Arterial 360 Better than “E” 5 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 2. Black Cat Road a. Existing Conditions: Black Cat Road is improved with 2-travel lanes, 23-feet of pavement and no curb, gutter or sidewalk abutting the site. There is 100-feet of right-of-way for Black Cat Road (50-feet from centerline). b. Policy: Arterial Roadway Policy: District Policy 7205.2.1 states that the developer is responsible for improving all street frontages adjacent to the site regardless of whether or not access is taken to all of the adjacent streets. Master Street Map and Typology Policy: District Policy 7205.5 states that the design of improvements for arterials shall be in accordance with District standards, including the Master Street Map and Livable Streets Design Guide. The developer or engineer should contact the District before starting any design. Street Section and Right-of-Way Width Policy: District Policies 7205.2.1 & 7205.5.2 state that the standard 5-lane street section shall be 59-feet (back-of-curb to back-of-curb) within 100- feet of right-of-way. This width typically accommodates two travel lanes in each direction, a continuous center left-turn lane or landscaped median with intermittent turn lanes, and curbs and gutters. A 5-lane road shall also include a minimum 10-foot multi-use path on both sides with an 8-foot buffer from back-of-curb. Other bike facility treatments as defined in the ACHD Bike Master Plan may be approved at the discretion of the ACHD Development Review Supervisor. If an interim on-street bike lane is required in order to connect to existing facilities, the street section shall be 75-feet to allow for a 5-foot bike lane and a 3-foot painter buffer. Right-of-Way Dedication: District Policy 7205.2 states that The District will provide compensation for additional right-of-way dedicated beyond the existing right-of-way along 6 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 arterials listed as impact fee eligible in the adopted Capital Improvements Plan using available impact fee revenue in the Impact Fee Service Area. No compensation will be provided for right-of-way on an arterial that is not listed as impact fee eligible in the Capital Improvements Plan. The District may acquire additional right-of-way beyond the site-related needs to preserve a corridor for future capacity improvements, as provided in Section 7300. Pedestrian Facilities: District Policy 7205.5.7 requires a concrete sidewalk at least 5-feet wide to be constructed on both sides of all arterial streets. A parkway strip at least 8-feet wide between the back-of-curb and street edge of the sidewalk is required to provide increased safety and protection of pedestrians. Alternatively, on roadways identified for improvement in the Capital Improvements Plan, a minimum 10-foot multi-use path may be required. The path shall be placed in accordance with planned buildout in the Master Street Map with a minimum 8-foot planter strip as measured to the closest edge of the path. Street trees are encouraged between the pedestrian facility and the roadway when irrigation and maintenance will occur by the adjacent property owner or HOA through an approved license agreement. Consult the District’s planter width policy if trees are to be placed within the parkway strip. In some instances, to match existing conditions, a minimum 7-foot sidewalk may be constructed next to the back-of- curb. ACHD Development Review staff will be responsible for determining the required facility. Vertical hardscape alternatives to street trees may be considered in the buffer space when street trees are not practicable. Detached sidewalks and multi-use paths are encouraged and should be parallel to the adjacent roadway. Pedestrian facilities will only be allowed to deviate from a straight line parallel to the roadway when authorized by Development Review staff to accommodate site specific conditions (i.e., street trees, utilities, etc.). Appropriate easements shall be provided if public pedestrian facilities are placed outside of the dedicated right-of-way. The easement shall encompass the entire area between the right-of- way line and 2-feet behind the back edge of the pedestrian facility. Pedestrian facilities shall either be located wholly within the public right-of-way or wholly within an easement. Curb ramps or blended transitions shall be provided to connect the pedestrian route at each pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable warning surface in accordance with the current version of PROWAG. Frontage Improvements Policy: District Policy 7205.2.1 states that the developer shall widen the pavement to a minimum of 17-feet from centerline plus a 3-foot wide gravel shoulder adjacent to the entire site. Curb, gutter and additional pavement widening may be required (See Section 7205.5.5). ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM) guide the right-of-way acquisition, arterial street requirements, and specific roadway features required through development. This segment of Black Cat Road is designated in the MSM as a Residential Arterial with 5-lanes and on-street bike lanes, a 72-foot street section within 100- feet of right-of-way. c. Applicant Proposal: The applicant is proposing to construct 5-foot wide detached concrete sidewalk on Black Cat Road abutting the site. The applicant is proposing to construct a 20-foot wide emergency access only driveway onto Black Cat Road located 646-feet south of the site’s north property line (measured from the north property line to centerline of the driveway). 7 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 d. Staff Comments/Recommendations: The applicant’s proposal to construct 5-foot wide detached concrete sidewalk on Black Cat Road abutting the site meets District policy; alternatively, a minimum 10-foot wide multi-use path may be required as this segment of Black Cat Road is listed in the CIP and ACHD Development Review staff will be responsible for determining the required pedestrian facility. Locate the pedestrian facility a minimum of 43-feet from centerline of Black Cat Road. Consistent with District Frontage Improvements, the applicant should be required to improve Black Cat Road with 17-feet of pavement plus a 3-foot wide gravel shoulder, where it does not exist, abutting the site. No additional dedication of right-of-way should be required as part of this application, as the existing right-of-way is consistent with the Master Street Map. The applicant should be required to construct a center two-way left-turn lane (if not constructed as part of Black Cat Industrial or Farmstone Crossing) on Black Cat Road when Vanguard Drive is constructed to intersect Black Cat Road. Compensation will not be provided for additional pavement widening or right-of-way dedication. The applicant’s proposal to construct a 20-foot wide emergency access only driveway onto Black Cat Road located 646-feet south of the site’s north property line should be approved as proposed. The emergency access only driveway should be restricted with a gate or bollards, located outside of the right-of-way, as determined by the appropriate fire department. 3. Vanguard Way-East/West Mid-Mile Collector a. Existing Conditions: There are no existing collector roadways within the site. 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 47-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. If a multi-use path is determined to be the required treatment, the street section shall be reduced to 37-feet. If it is determined a continuous center left-turn lane is not appropriate and a path is installed, the street section may be reduced to 26-feet. Pedestrian Facility: District policy 7206.5.6 requires a concrete sidewalk at least 5-feet wide to be constructed on both sides of all collector streets. A parkway strip at least 8-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. Alternatively, on roadways identified as low-stress bikeways in ACHD’s Bike Master Plan, a minimum 10-foot multi-use path may be required in lieu of sidewalks. ACHD 8 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 Development Review staff will be responsible for determining the required facility. The path shall be built 8-feet behind the top back of curb as measured to the closest edge of the path. Street trees are encouraged between the pedestrian facility and the roadway when irrigation and maintenance will occur by the adjacent property owner or HOA through an approved license agreement. Vertical hardscape alternatives to street trees may be considered in the buffer space when street trees are not practicable. Pedestrian facilities should be parallel to the adjacent roadway. Pedestrian facilities will only be allowed to deviate from a straight line when authorized by Development Review staff to meet site specific conditions (i.e. street trees, utilities, etc.). Appropriate easements shall be provided if public sidewalks or multi-use paths are placed out of the right-of-way. The easement shall encompass the entire area between the right-of-way line and 2-feet behind the back edge of the sidewalk or multi-use path. Sidewalks shall either be located wholly within the public right-of-way or wholly within an easement. Curb ramps or blended transitions shall be provided to connect the pedestrian route at each pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable warning surface in accordance with the current version of PROWAG. 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. A new collector roadway was identified on the MSM with the street typology of Towncenter Collector. The new collector roadway should align with Vanguard Drive, an approved collector roadway on the west side of Black Cat Road across from the site and continue through the property stubbing to the east. The MSM recommends the Towncenter Collector be constructed as a 3-lane roadway with bike lanes, a 47-foot wide street section within 78-feet of right-of-way. c. Applicant Proposal: The applicant is proposing to construct the new east/west collector street, referred to as Street A on the site plan, as ½ of a 40-foot wide street section with vertical curb, gutter, an 8-foot wide planter strip and 5-foot wide detached concrete sidewalk on the north side of the roadway and 12-feet of pavement on the south side of the roadway. d. Staff Comments/Recommendations: ACHD recently approved plans for the construction of Vanguard Drive as a 5-lane roadway at the intersection with Black Cat Road as part of the Black Cat Industrial development located on the west side of Black Cat Road across from the site. Consistent with the requirements of Vanguard Drive on the west side of Black Cat Road across from the site, Farmstone Crossing, located directly south of the site was required to match the improvements and construct Vanguard Drive from Black Cat Road east 275-feet as a 72-foot wide street section with 5-lanes (two eastbound receiving lanes, two westbound left-turn lanes, and a westbound thru/right-turn lane) vertical curb, gutter and 7-foot wide attached or 5-foot wide detached concrete sidewalk located through their site. The remaining segment of Vanguard Drive was required to be constructed as a 47-foot wide street section with 3-lanes, vertical curb, gutter and 7-foot wide attached or 5-foot wide detached concrete sidewalk. Therefore, the applicant should be required to construct the remaining portion of Vanguard Drive (shown as Street A on the site plan) east of the 5-lane portion of the roadway (275-feet east of Black Cat Road) as ½ of a 47-foot wide street section with vertical curb, gutter and 7-foot wide attached or 5-foot wide detached concrete sidewalk or a 10-foot wide pathway. If a 10-foot wide pathway is built, then the street section should be reduced to 37-feet and on-street bike lanes and the 5-foot detached or 7-foot wide attached concrete sidewalk should not be required. ACHD Development Review staff will be responsible for determining the required facility. The applicant should be required to dedicate right-of-way to 2-feet behind back of sidewalk, or for detached sidewalk, the applicant may reduce the right-of-way to 2-feet behind the back of curb and provide a permanent right-of-way easement that extends from the right-of-way line to 9 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 2-feet behind back of sidewalk. Sidewalk shall be located wholly within right-of-way or wholly within an easement. If street trees are desired, an 8-foot wide planter strip should be required. 4. Internal Local Streets a. Existing Conditions: There are no local streets within the site. b. Policy: Reduced Urban Local Street—27-foot Street Section and Right-of-Way Policy: District Policy 7207.5.2 states that the width of a reduced urban local street shall be 27-feet (back-of- curb to back-of-curb) with curb, gutter, and minimum 5-foot concrete sidewalks on both sides and shall typically be within 41-feet of right-of-way. Unless approved in writing by the land use agency, this street section is not allowed by the City of Kuna and City of Star. In some cases this street width may not acc7ommodate new utilities. A 29-foot street section within 43-feet of right-of-way may be constructed in lieu of a 27-foot street section if the applicant demonstrates that the additional roadway width is necessary to extend the utilities. Although some parking is allowed by the following subsections, the District will further restrict parking on a reduced width street if curves or other physical features cause problems, if actual emergency response experience indicates that emergency vehicles may not be able to provide service, or if other safety concerns arise. One of the following three sets of design conditions shall apply. Design Condition #1: Parking is allowed on one side of a reduced width street when all of the following criteria are met: • The street is in a residential area. • The developer shall provide written approval from the appropriate fire department or emergency response unit in the jurisdiction. • The developer shall install NO PARKING signs on one side of the street, as specified by the District and as specified by the appropriate fire department. • This street section shall include curb, gutter, and minimum 5-foot wide concrete sidewalks on both sides and shall typically be constructed within 41-feet of right-of-way. • Traffic volumes on the street shall not exceed 1,000 vehicle trips per day. There shall be no possibility that another street may be connected to it in a manner that would allow more than 1,000 vehicle trips per day. Design Condition #2: Parking is allowed on both sides of a reduced width street when the street layout has the qualities of a road grid system. This provides fire trucks and other emergency vehicles alternate routes of access since the ability to pass another vehicle may be compromised by placement of parked vehicles on both sides of the street. The following criteria shall be met: • The street is in a residential area. • The developer shall provide written approval from the appropriate fire department or emergency response unit in the jurisdiction. • The block length of the street shall not exceed 500-feet, measured between centerlines. • Traffic volumes on the street are not forecast to exceed 400 vehicle trips per day. • A minimum of two street connections shall be provided to each end of the street with the reduced width. The two connecting streets shall each connect to the larger street system to provide the intended alternate routes of access. A street system that has o ne street connection to the larger street network on one end and a loop/circle street on the other end with no outlet shall not be approved. • This street section shall include curb, gutter, and minimum 5-foot wide concrete sidewalks on both sides and shall typically be constructed within 41-feet of right-of-way. 10 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 Design Condition #3: Parking is allowed on both sides of a reduced width residential street with passing pockets that are created when two driveways are constructed near the same property line, where a 50-foot segment will not have on–street parking on the side of the street with the driveways. This provides fire trucks and other vehicles areas to move to the side of the street to allow another vehicle to pass when vehicles are parked on the street. Parking is allowed on both sides of a reduced width street when the following criteria are met: • The street is in a residential area. • The developer shall provide written approval from the appropriate fire department or emergency response unit in the jurisdiction. • Driveway locations are predetermined with curb cuts for the driveways to be installed when the street is constructed. The curb cuts shall be 20-feet wide. Each lot on the street will be paired with an adjacent lot. If there are an odd number of lots, one lot at either end of the street will not be paired. Each pair of lots shall locate its driveway 5-feet from the shared lot line of the pair. • This street section shall include curb, gutter, and minimum 5-foot wide concrete sidewalks on both sides and shall typically be constructed within 41-feet of right-of-way. • The lots cannot abut an alley. • Traffic volumes on the street are not forecast to exceed 400 vehicle trips per day. 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 47-feet wide and that the standard street section shall be 33-feet (back-of-curb to back-of-curb). Standard Urban Local Street—33-foot Street Section and Right-of-way Policy: District Policy 7207.5.2 states that the standard street section shall be 33-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 wide concrete sidewalks on both sides and shall typically be constructed within 47-feet of right-of-way. 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. 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 right- of-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. Cul-de-sac Streets Policy: District policy 7207.5.8 requires cul-de-sacs to be constructed to provide a minimum turning radius of 50-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 11 DRAFT Avani Subdivision/ MPP23-0010/ H-2023-0049 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. Landscape Medians Policy: District policy 7207.5.16 states that landscape medians are permissible where adequate pavement width is provided on each side of the median to accommodate the travel lanes and where the following is provided: • The median is platted as right-of-way owned by ACHD. • The width of an island near an intersection is 12-feet maximum for a minimum distance of 150-feet. Beyond the 150-feet, the island may increase to a maximum width of 30-feet. • At an intersection that is signalized or is to be signalized in the future, the median width shall be reduced to accommodate the necessary turn lane storage and tapers. • The Developer or Homeowners Association shall apply for a license agreement if landscaping is to be placed within these medians. • The license agreement shall contain the District’s requirements of the developer including, but not limited to, a “hold harmless” clause; requirements for maintenance by the developer; liability insurance requirements; and restrictions. • Vertical curbs are required around the perimeter of any raised median. Gutters shall slope away from the curb to prevent ponding. c. Applicant’s Proposal: The applicant is proposing to construct the entrance roadway, Street B, from the intersection with the new east/west collector roadway, Street A, to the intersection with Street D with two 21-foot wide travel lanes, three 10-foot wide center landscape islands, vertical curb and gutter within 56-feet of right-of-way and an 8-foot wide planter strip and 5-foot wide detached concrete sidewalk within a 13-foot wide permanent right-of-way easement. The applicant is proposing to construct all other internal local streets as 27-foot wide street section with curb and gutter within 31-feet of right-of-way and an 8-foot wide planter strip and 5-foot wide detached concrete sidewalk within a 13-foot wide permanent right-of-way easement. d. Staff Comments/Recommendations: The applicant’s proposal to construct the entrance roadway, Street B, from the intersection with the new east/west collector roadway, Street A, to the intersection with Street D with two 21-foot wide travel lanes, three 10-foot wide center landscape islands, vertical curb and gutter within 56-feet of right-of-way and an 8-foot wide planter strip and 5-foot wide detached concrete sidewalk within a 13-foot wide permanent right- of-way easement meets District policy and should be approved, as proposed. The three 10-foot wide center landscape islands should be platted as right-of-way owned by ACHD.
