Lead Agency: City of Meridian Site address: 4111 E. Amity Road and 5200 S. Hillsdale Avenue Staff Approval: July 26, 2021 Applicant: Becky McKay Engineering Solutions, LLP 1029 N. Rosario Street, Suite 100 Meridian, ID 83642 Representative: Same as above Staff Contact: Paige Bankhead, E.I. Phone: 387-6293 E-mail: pbankhead@achdidaho.org A. Findings of Fact 1. Description of Application: The applicant is requesting approval of an annexation and rezone application to annex 40.49 acres into the City of Meridian with a R-8 and R-15 zoning and a preliminary plat application to develop 124 single-family lots, 35 townhome lots, 2 multi-family lots, 1 commercial lot and 27 common lots on 38.95 acres. The City of Meridian’s Future Land Use Plan designates this area as Old Town and Medium Density Residential. 2. Description of Adjacent Surrounding Area: Direction Land Use Zoning North Medium Density Residential R-8 South Medium Density Residential R-8 East Medium Density Residential (City of Boise) R-4 West Neighborhood Business C-N 3. Site History: ACHD has not previously reviewed this site for a development application. 4. Adjacent Development: The following developments are pending or underway in the vicinity of the site: Vicinity Map 2 Centerville Subdivision MPP20-0018/ H-2021-0046 • Shelburne South Subdivision, 99 single-family lots and 19 common lots on 27.9 acres located directly north of the site and was approved by ACHD on December 23, 2019. 5. Transit: Transit services are not available to serve this site. 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. New Center Lane Miles: The proposed development includes 1.10 centerline miles of new public road. 8. 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. 9. Capital Improvements Plan (CIP)/ Integrated Five Year Work Plan (IFYWP): • Eagle Road is scheduled in the IFYWP to be widened to 5-lanes from Amity Road to Victory Road in 2021-2022. • Cloverdale Road is schedule in the IFYWP to be widened to 5-lanes from Amity Road to Victory Road in 2025. • The intersection of Eagle Road and Amity Road is scheduled in the IFYWP to be reconstructed as a multi-lane roundabout with 4-lanes on the north leg, 4-lanes on the south, 4-lanes east, and 4-lanes on the west leg and is currently under construction. • The intersection of Cloverdale Road and Amity Road is scheduled in the IFYWP to be reconstructed as a multi-lane roundabout with 4-lanes on the north leg, 4-lanes on the south leg, 4-lanes on the north leg, 2-laneson the east leg and 2-laneson the west leg in 2025. • Amity Road is listed in the CIP to be widened to 3-lanes from Eagle Road to Cloverdale Road between 2036 and 2040. 10. 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 Amity Road as a Level 3 facility that will be constructed as part of a future ACHD project. 3 Centerville Subdivision MPP20-0018/ H-2021-0046 • The BMP identifies Hillsdale Avenue, a collector road, as a Level 1 facility. Hillsdale Avenue is currently striped with bike lanes on both sides of the road. B. Traffic Findings for Consideration 1. Trip Generation: This development is estimated to generate 2,599 additional vehicle trips per day; 266 additional vehicle trips per hour in the PM peak hour, based on the traffic impact study. 2. Traffic Impact Study CR Engineering, Inc. prepared a traffic impact study for the proposed Centerville Subdivision. An executive summary of the findings as presented by CR Engineering, Inc. can be found as Attachment 3. The executive summary is not the opinion of ACHD staff. ACHD has reviewed the submitted traffic impact study for consistency with ACHD policies and practices, and may have additional requirements beyond what is noted in the summary. ACHD Staff comments on the submitted traffic impact study can be found below under staff comments. Intersections (blue) and roadway segments (green) included in the study a. Policy Mitigation Proposals: Mitigation recommendations shall be provided within the report. At a minimum, for each roadway segment and intersection that does not meet the minimum acceptable level of service planning threshold or v/c ratio, the report must discuss feasible measures to avoid or reduce the impact to the system. To be considered adequate, measures should be specific and feasible. Mitigation may also include: • Revision to the Phasing Plan to coincide with the District’s planning Capital Projects. • Reducing the scope and/or scale of the project. Alternative Mitigation Measures: 7106.7.3 states that if traditional mitigation measures such as roadway widening and intersection improvements are infeasible as determined by ACHD, the TIS may recommend alternative mitigation measures. Alternative mitigation measures shall demonstrate that impacts from the project will be offset. 4 Centerville Subdivision MPP20-0018/ H-2021-0046 • If the impacted roadway segments and/or intersections are programmed as funded in the Integrated Five Year Work Plan (IFYWP) or the Capital Improvements Plan (CIP); no alternative mitigation is required. • If the impacted roadway segments and/or intersections are not programmed in either the IFYWP or the CIP; the applicant may (i) analyze the shoulder hour and (ii) provide a safety analysis to determine alternative mitigation requirements. o If the impacted roadway segments and intersections meet the minimum acceptable level of service planning thresholds in the shoulder hour the applicant may suggest feasible alternative mitigation such as: sidewalks, bike facilities, connectivity, safety improvements, etc. within 1.5 miles of the proposed development. o If the shoulder hour planning thresholds are exceeded the applicant may request to enter into a Development Agreement and pay into the Priority Corridor Fund an amount determined by the ACHD to offset impacts from the project. • Alternative Mitigation may also include: o Revision to the Phasing Plan to coincide with the District’s future Capital Projects. o Reducing the scope and/or scale of the project. Level of Service Planning Thresholds: District Policy 7206.4.1 states that, Level of Service Planning Thresholds have been established for principal arterials and minor arterials within ACHD’s Capital Improvement Plan and are also listed in section 7106. Unless otherwise required to provide a Traffic Impact Study under section 7106, a proposed development with site traffic less than 10% of the existing downstream roadway or intersection peak hour traffic shall not be required to provide mitigation for a roadway or intersection that currently exceeds the minimum acceptable level of service planning threshold or V/C ratio. b. Staff Comments/Recommendations: Staff has reviewed the submitted traffic impact study (TIS) and generally agrees with the findings and recommendations. The table below summarizes the improvements required with the development based on the study and District Policy. The following sections summarize staff’s recommendations based on the study’s findings and recommendations. Summary of Improvements Required by ACHD Intersection Improvement Threshold Hillsdale Avenue/Amity Road Interim Signal 60 PM peak hour trips Amity Road/Amorita Avenue Dedicated eastbound right-turn lane and westbound left-turn lane With first phase of development Amity Road The study shows that Amity Road from Eagle Road to Cloverdale Roads exceeds ACHD LOS thresholds for a 2-lane arterial roadway in the PM peak hour, but meets thresholds for a 3-lane arterial roadway. This segment of Amity Road has center left turn lanes at all major subdivision access points, allowing the roadway to function as a 3-lane minor arterial roadway and meet LOS thresholds. However, the study shows that this segment of Amity Road will exceed the thresholds for a 3-lane arterial roadway under the 2025 background and total traffic conditions when 97 PM peak hour trips are added to the road segment from Eagle Road to the site access and 105 PM peak hour trips are added to the segment from the site access to Cloverdale Road. This roadway is constrained to 3-lanes based on the Master Street Map. 5 Centerville Subdivision MPP20-0018/ H-2021-0046 The peak hour site traffic for Amity Road between the site and Eagle Road is 9.9% of the 2025 total traffic, and 6.7% of the 2025 total traffic from the site to Cloverdale Road. District Policy for alternative mitigation measures states that if the site traffic is less than 10% of the total traffic conditions for intersections or roadways segments that exceed ACHD LOS thresholds, or the roadway segment or intersection is listed in the CIP then improvements are not required. In addition, it is infeasible for the applicant to widen this segment of Amity Road due to right -of- way constraints and the Master Street Map constrains this roadway to 3-lanes. Therefore, staff does not recommend that the applicant be required to construct any additional improvements to this segment of Amity Road with this development application. Eagle Road/Amity Road Intersection The intersection of Eagle Road and Amity Road is currently being improved by ACHD as a multi-lane roundabout with 4-lanes on each leg per the IFYWP. The study shows that the intersection will meet ACHD’s LOS thresholds under the existing and 2025 background traffic conditions. The study recommends constructing a southbound right-turn lane at the intersection to mitigate the 2025 total traffic conditions. The peak hour site traffic at this intersection is 4.5% of the 2025 total traffic. District Policy for alternative mitigation measures states that if the site traffic is less than 10% of the total traffic conditions for an intersection or roadway segment that exceeds ACHD LOS thresholds, improvements are not required. Therefore, staff does not recommend that the applicant be required to construct any additional improvements to the intersection of Eagle Road/Amity Road with this development application. Cloverdale Road/Amity Road Intersection The study recommends reconstructing the intersection as a multi-lane roundabout or construct dedicated southbound and westbound right-turn lanes to mitigate the 2025 total traffic conditions. The peak hour site traffic at this intersection is 4.3% of the 2025 total traffic conditions and this intersection is listed in the IFYWP to be improved as a multi-lane roundabout in 2025. District Policy for alternative mitigation measures states that if the site traffic is less than 10% of the total traffic conditions for an intersection or roadway segment in the study that exceeds ACHD LOS thresholds or the intersection or roadway segment is listed in the CIP or IFYWP, improvements are not required. Therefore, staff does not recommend that the applicant be required to construct any additional improvements to the intersection of Cloverdale Road/Amity Road with this development application. Hillsdale Avenue/Amity Road The study recommends signalizing the intersection of Hillsdale Avenue and Amity Road, or reconstructing the intersection as a single-lane roundabout, when 60 PM peak hour trips are added to the intersection. This intersection is shown as a single-lane roundabout on the Master Street Map, however, this is not enough existing right-of-way to reconstruct the intersection as a single-lane roundabout. Therefore, the applicant should be required to install an interim signal at this intersection prior to ACHD’s final approval and signature on the final plat that generates 61 PM peak hour trips, or has 61 single family lots, consistent with the study recommendations, see Finding 2. The intersection is currently improved with a dedicated eastbound right-turn lane, northbound right-turn lane, northbound left-turn lane and an east/west center left-turn lane that extends through the intersection. The applicant will be required to dedicate additional right-of- way abutting the site for the future single-lane roundabout. Site Access The study recommends constructing a dedicated eastbound right-turn lane and dedicated westbound left-turn lane on Amity Road when Amorita Avenue is constructed to intersect Amity Road. The applicant should be required to construct the turn lanes when Amorita Avenue is constructed to intersect Amity Road consistent with the study’s recommendation. Shelburne South Subdivision directly north of the site was required to construct a center left turn lane on 6 Centerville Subdivision MPP20-0018/ H-2021-0046 Amity Road at Amorita Avenue that tapers to the east. The applicant should coordinate with Shelburne South Subdivision for the construction of the westbound left-turn lane on Amity Road. The study indicates that turn lanes are not warranted on Hillsdale Avenue at Hill Park Street. Traffic Distribution The adjacent neighborhoods to the south of the site have voiced concerns about potential cut- through traffic from this development through their neighborhoods to reach arterial roadways, Amity Road and Cloverdale Road. The study notes that the circulation proposed for the development will provide direct access to Hillsdale Avenue and Amity Road for the development. The site traffic is not expected to travel to the south to reach Amity Road or Cloverdale Road since direct access to Amity Road is available through the site via Amorita Avenue and Hillsdale Avenue. It is not practical that the traffic from the site will travel to the south and cut through the adjacent neighborhoods to reach Amity Road and Cloverdale Road since it would require numerous turns and out of direction travel on local neighborhood streets. In addition, the intersection of Amity Road and Cloverdale Road is scheduled in the IFYWP to be improved in 2025, which is expected to improve intersection operations and reduce the demand for cut-through routes in the area. Pedestrian Crossing – Hillsdale Avenue The adjacent neighborhoods have also expressed concerns about safe routes to the school and YMCA directly across Hillsdale Avenue to the west of the site. Staff recommends that the applicant consider striping a crosswalk and installing a rapid rectangular flashing beacon (RRFB) on Hillsdale Avenue at the intersection with Rockhampton Street or Hill Park Street to provide a safe crossing for pedestrians to the YMCA and school. The applicant will be responsible for the design, hardware, and installation of pedestrian crossing and would be required to enter into a signal agreement with ACHD. See Finding 6. 3. Condition of Area Roadways Traffic Count is based on Vehicles per hour (VPH) * Acceptable level of service for a two-lane minor arterial is “E” (575 VPH). * Acceptable level of service for a three-lane minor arterial is “E” (720 VPH). * Acceptable level of service for a two-lane collector is “D” (425 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 Amity Road from the site to Eagle Road was 7,416 on 08/29/2019. Roadway Frontage Functional Classification PM Peak Hour Traffic Count PM Peak Hour Level of Service Existing Plus Project Amity Road (between the site and Eagle Road) 1,300-feet Minor Arterial 615 Better than “E” for 3-lane arterial, “F” for 2-lane arterial “F” Amity Road (from the site to Cloverdale Road) 1,300-feet Minor Arterial 623 Better than “E” for 3-lane arterial, “F” for 2-lane arterial “F” 7 Centerville Subdivision MPP20-0018/ H-2021-0046 • The average daily traffic count for Amity Road from the site to Cloverdale Road was 6,718 on 08/26/2019. C. Findings for Consideration 1. South Meridian Transportation Plan The South Meridian Transportation Plan (SMTP) is a long range planning tool used to identify future roadway, intersection, and corridor needs in the South Meridian Area, providing a framework for future roadway improvements based on the land use designations. The plan was created in collaboration with the City of Meridian and was adopted by the ACHD Commission in September of 2009. The SMTP shows Amity Road east of Eagle Road as a 3-lane arterial roadway, but recommends preserving right-of-way for a 5-lane arterial roadway for this segment due to the potential for additional traffic demands beyond 2030. The Master Street Map shows 78-feet of right- of-way preservation for a 3-lane arterial roadway for this segment of Amity Road. The Master Street Map is updated every 2 years and was recently updated and adopted by the ACHD Commission in October 2020. The applicant will be required to dedicate additional right-of-way abutting the site consistent with the Master Street Map since it is the most recently updated guiding document accepted by the ACHD Commission. 2. Amity Road/Hillsdale Avenue Intersection – Signal The study recommends signalizing the intersection of Amity Road and Hillsdale Avenue or reconstructing the intersection as a single lane roundabout when 60 PM peak hour trips are added to the intersection, or 60 single family lots are platted. This intersection is shown on the Master Street Map as a single-lane roundabout, however, there is not enough right-of-way to construct a single-lane roundabout with this development. Therefore, the applicant should be required to signalize the intersection as a 3 X 3 interim signal prior to ACHD’s final approval and signature on the final plat that contains the 61st single family lot or the final plat the generates 61 PM peak hour trips. In order to install the interim signal at the Amity Road/Hillsdale Avenue intersection, the applicant will need to obtain plan approval and enter into a signal agreement with ACHD. ACHD will provide the signal hardware since ACHD has a signal planned at this intersection. The signal agreement should include requirements that the intersection be designed as a 3 X 3 intersection in its current configuration with the eastbound left turn lane striped out; that the applicant is responsible for all costs associated with the design and installation of the interim signal and that interim improvements are not eligible for reimbursement by ACHD. In order to ensure the Amity Road/Hillsdale Avenue intersection will be improved when warranted, the following items must be in place prior to plans acceptance of the final plat that contains the 61st single family lot, or generates 61 PM peak hour trips: • Signal Agreement; • Full design and approved plans for the intersection. 3. Amity Road/Hillsdale Avenue – MSM Roundabout a. ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM) guide the right-of-way acquisition, collector street requirements, roundabout requirements, and specific roadway features required through development. A new roundabout was identified on the MSM. The new single-lane roundabout is planned at the mid-mile at the Amity Road/Hillsdale Avenue intersection. b. Staff comments/Recommendation: The Master Street Map shows a single-lane roundabout located at the intersection of Amity Road and Hillsdale Avenue. Additional right-of-way should be dedicated to accommodate the future construction of the single-lane roundabout as shown 8 Centerville Subdivision MPP20-0018/ H-2021-0046 below; the placement of the roundabout should be shifted to so that the south leg aligns with the Hillsdale Avenue. The template for a single-lane roundabout can be found as Attachment 4. 4. Adjacent Neighborhood Concerns The adjacent neighborhoods to the south of the site have voiced concerns about potential cut - through traffic from this development through their neighborhoods in order to reach arterial roadways, Amity Road and Cloverdale Road, and are concerned about the gap in sidewalk on the west side of Hillsdale Avenue just north of the school. The traffic impact study notes that the circulation proposed for the development will provide direct routes to Hillsdale Avenue and Amity Road for the development. The site traffic is not expected to travel to the south to reach Amity Road or Cloverdale Road since direct access to Amity Road to reach Cloverdale Road is available through the site via Amorita Avenue and Hillsdale Avenue. It is not practical that the site traffic will travel to the south and cut through the adjacent neighborhoods to reach Amity Road and Cloverdale Road since it would require numerous turns and out of direction travel on local neighborhood streets. In addition, the intersection of Amity Road and Cloverdale Road is scheduled in the IFYWP to be improved in 2025, which is expected to improve intersection operations and would reduce the demand for cut-through routes in the area. Sidewalk cannot be constructed with this development to fill the gap in improvements on the west side of Hillsdale Avenue abutting the existing residence shown below at this time due the life estate for that home. The existing residence was originally part of a larger parcel that was recently 9 Centerville Subdivision MPP20-0018/ H-2021-0046 subdivided for the YMCA and the residence known as Healthy Living Subdivision and was approved by ACHD in 2017. As part of ACHD’s action on that development, sidewalk was not required to be constructed abutting the life estate and when the life estate is removed, sidewalk is required to be constructed on Hillsdale Avenue to fill in the gap in improvements. If sidewalk were permitted to be constructed abutting the life estate, it would have been constructed with the development of Healthy Living Subdivision. Gap in Sidewalk on Hillsdale Avenue The adjacent neighborhoods have also expressed concerns about safe routes to the school and the YMCA directly across the Hillsdale Avenue to the west of the site. Staff recommends that the applicant consider striping a crosswalk and installing a rapid rectangular flashing beacon (RRFB) on Hillsdale Avenue at the intersection with Rockhampton Street or Hill Park Street to provide a safe crossing for pedestrians to the YMCA and school, see the figure below. The applicant would be responsible for the design, hardware, and installation of pedestrian crossing and would be required to enter into a signal agreement with ACHD. The applicant has indicated that they are supportive of this recommendation, but do not have a location at this time. See Finding 6. 10 Centerville Subdivision MPP20-0018/ H-2021-0046 Potential locations for an RRFB pedestrian crossing on Hillsdale Avenue 5. Amity Road – Minor Arterial Road a. Existing Conditions: Amity Road is improved with 2-travel lanes with a center left turn lane at Hillsdale Avenue and no curb, gutter or sidewalk abutting the site. There is 55 to 62-feet of right-of-way for Amity Road (28-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 Distr ict 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 Policy 7205.2.1 & 7205.5.2 states that the standard 3-lane street section shall be 46-feet (back-of-curb to back-of-curb) within 70 feet of right-of-way. This width typically accommodates a single travel lane in each direction, a continuous center left-turn lane, and bike lanes. 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 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. 11 Centerville Subdivision MPP20-0018/ H-2021-0046 Sidewalk Policy: 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 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 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. 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 Amity Road is designated in the MSM as a Residential Arterial with 3-lanes and on-street bike lanes, a 46-foot street section within 78-feet of right-of-way. c. Applicant Proposal: The applicant has proposed to dedicate additional right-of-way for Amity Road abutting the site to total 37-feet from the centerline of the roadway and construct a 10- foot wide concrete multi-use pathway located outside of the right-of-way. d. Staff Comments/Recommendations: The applicant should be required to dedicate additional right-of-way for Amity Road abutting the site to total 39-feet from the centerline of the roadway consistent with the MSM and widen the pavement to 17-feet from the centerline of the roadway with a 3-foot wide gravel shoulder where deficient abutting the site. The applicant’s proposal to construct a 10-foot wide multi-use pathway abutting the site exceeds District Policy, which only requires 5-foot wide detached or 7-foot wide attached concrete sidewalk. However, staff is supportive of the applicant’s proposal due to the fact that it is the desire and direction of the ACHD Commission to construct 10-foot wide multi-use pathways on arterial roadways with new development. An interim policy is currently being drafted to implement this requirement with new developments. However, since this is currently not required by District Policy, the applicant should be required at a minimum to construct a 5-foot wide detached concrete sidewalk located a minimum of 32-feet from the centerline of the roadway consistent with the current District Policy. For detached sidewalk or multi-use pathways located outside of the right-of-way, the applicant should be required to provide a permanent right-of-way easement that extends from the right-of-way line to 2-feet behind the multi-use pathway or sidewalk. The applicant should be required to construct a dedicated eastbound right-turn lane and westbound left-turn lane on Amity Road at Amorita Avenue when it is constructed to intersect Amity Road, consistent with the study recommendations. The applicant should coordinate the construction of the westbound left-turn lane with Shelburne South Subdivision directly north of the site since this subdivision was required by ACHD to construct a center left turn lane on Amity Road at Amorita Road that is proposed to taper to the east. The construction plans for this turn lane have been approved by ACHD. 6. Hillsdale Avenue and Hill Park Street – Collector Roads a. Existing Conditions: Hillsdale Avenue is improved with 2-travel lanes and 3-lanes at Amity Road, vertical curb, gutter and no sidewalk abutting the site. There is 40 to148-feet of right-of- way for Hillsdale Avenue (22 to 65-feet from centerline). b. Policy: 12 Centerville Subdivision MPP20-0018/ H-2021-0046 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 t he 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 sidewalk 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 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. Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing streets adjacent to a proposed development may be required. These improvements are to correct deficiencies or replace deteriorated facilities. Included are sidewalk construction or replacement; curb and gutter construction or replacement; replacement of unused driveways with curb, gutter and sidewalk; installation or reconstruction of pedestrian ramps; pavement repairs; signs; traffic control devices; and other similar items. 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 Hillsdale Avenue is designated in the MSM as a Residential Collector with 2-lanes and on-street bike lanes, a 36-foot street section within 50-feet of right-of-way. Landscape Medians Policy: District policy 7206.5.16 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: 13 Centerville Subdivision MPP20-0018/ H-2021-0046 • 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 Proposal: The applicant has proposed to construct a 5-foot wide detached concrete sidewalk with a minimum 8-foot wide planter strip on Hillsdale Avenue abutting the site. The sidewalk is proposed to be located outside of the right-of-way. The applicant has proposed to construct Hill Park Street as a 36-foot wide collector street section with vertical curb, gutter, 8-foot wide planter strips within 47-feet of right-of-way and 5- foot wide detached concrete sidewalks located outside of the right-of-way. The applicant has proposed to construct a 10-foot wide landscaped median at the entrance of Hill Park Street in order to restrict the western most driveways on Hill Park Street to right-in/right- out only. The applicant has proposed to stripe a crosswalk across Hill Park Street on the east side of the western most driveways. 14 Centerville Subdivision MPP20-0018/ H-2021-0046 d. Staff Comments/Recommendations: The applicant’s proposal meets District Policy and should be approved, as proposed. The applicant should be required to construct the entry portion of Hill Park Street with a 10-foot wide landscaped median, as proposed, that extends from the entrance of Hill Park Street to 75-feet to the east beyond the edge of the western driveways and 20-foot wide travel lanes on either side of the median with vertical curb, gutter and 5-foot wide detached or 7-foot wide attached concrete sidewalk within right-of-way that extends to 2-feet behind the back of sidewalk. If street trees are desired, an 8-foot wide planter strip is required. For detached sidewalk located outside of the right-of-way, should be required to provide a permanent right-of-way easement that extends from the right-of-way line to 2-feet behind the back of sidewalk. The applicant should be required to move to the crosswalk to the west so that it aligns the with the north/south sidewalk/pathway and extends from the corners of the driveways across Hill Park Street, install pedestrian crossing signs in advance of the crossing and at the crossing, and install street lighting at the crossing. On-street parking will not be allowed on this roadway. The applicant should be required to replace any broken segments of curb and gutter abutting the site on Hillsdale Avenue consistent with the District’s Minor Improvements Policy. Hillsdale Avenue Pedestrian Crossing The adjacent neighborhoods have expressed concerns about safe routes to school and the YMCA directly across the street from the site. Staff recommends that the applicant consider striping a crosswalk and installing a rapid rectangular flashing beacon (RRFB) on Hillsdale Avenue south of the intersection with Rockhampton Street or Hill Park Street to provide a safe crossing for pedestrians to the school and the YMCA. The applicant has indicated that they are supportive of this recommendation, but has not yet finalized plans for the crossing. The applicant would be responsible for the design, hardware and installation of pedestrian crossing and would enter into a signal agreement with ACHD. If the applicant chooses to install an RRFP on Hillsdale Avenue at Rockhampton Street or Hill Park Street, the applicant will need to obtain plan approval, purchase the signal equipment, and enter into a signal agreement with ACHD. The applicant will need to order and purchase the signal hardware as ACHD does not have these materials available for this project. The signal agreement should include requirements that the applicant is responsible for all costs associated with the hardware, design, and installation of the flashing beacon, and that this improvement is not eligible for reimbursement by ACHD. In order to ensure the RRFB with intersection lighting on Hillsdale Avenue is installed, the following items must be in place prior to plans acceptance. • Signal Agreement • Full design and approved plans for the crossing 7. Internal Local Roads a. Existing Conditions: There are no local roadways within the site. There is one local street, Beachfield Avenue, that stubs to the site’s south property line and another local street, Macumbo Street, that stubs to the site’s east property line. 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. 15 Centerville Subdivision MPP20-0018/ H-2021-0046 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. For the City of Kuna and City of Star: Unless otherwise approved by Kuna or Star, 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 wide concrete sidewalks on both sides and shall typically be constructed within 50-feet of right-of-way. Continuation of Streets Policy: District Policy 7207.2.4 states that an existing street, or a street in an approved preliminary plat, which ends at a boundary of a proposed development shall be extended in that development. The extension shall include provisions for continuation of storm drainage facilities. Benefits of connectivity include but are not limited to the following: • Reduces vehicle miles traveled. • Increases pedestrian and bicycle connectivity. • Increases access for emergency services. • Reduces need for additional access points to the arterial street system. • Promotes the efficient delivery of services including trash, mail and deliveries. • Promotes appropriate intra-neighborhood traffic circulation to schools, parks, neighborhood commercial centers, transit stops, etc. • Promotes orderly development. 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. 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: 16 Centerville Subdivision MPP20-0018/ H-2021-0046 • 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 has proposed to extend 2 local stub streets , Beachfield Avenue and Macumbo Street, into the site. The applicant has proposed to construct the entrance of Amorita Avenue as a 52-foot wide street section with two 21-foot wide travel lanes (measured back-of-curb to back-of-curb), a 9- foot wide landscaped median, vertical curb, gutter, 8-foot wide plater strips and 5-foot wide detached concrete sidewalk within 79-feet of right-of-way that extends to 1-foot behind the back of sidewalk. The applicant has proposed to construct all other internal local streets as 33-foot wide local street streets with rolled curb, gutter, with 5-foot wide attached concrete sidewalks within 47- feet of right-of-way or 8-foot wide planter strips and 5-foot wide detached concrete sidewalks located outside of the right-of-way. d. Staff Comments/Recommendations: The applicant’s proposal meets District Policy and should be approved, as proposed. The applicant should also be required to dedicate additional right-of-way for Amorita Avenue so that it extends to 2-feet behind the back of sidewalk. For detached sidewalk, the applicant may reduce the right-of-way width 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 2-feet behind the back of sidewalk. The applicant should be required to plat the landscaped medians as right-of-way owned by ACHD. The applicant or homeowners association should be required to enter into a license agreement with ACHD for the maintenance of the landscaping. 8. Roadway Offsets a. Existing Conditions: There are no roadways within the site. b. Policy: Local Street Intersection Spacing on Minor Arterials: District policy 7205.4.3 states that new local streets should not typically intersect arterials. Local streets should typically intersect collectors. If it is necessary, as determined by ACHD, for a local street to intersect an arterial, the minimum allowable offset shall be 660-feet as measured from all other existing roadways as identified in Table 1a (7205.4.6). Collector Offset Policy: District policy 7206.4.5, states that the preferred spacing for a new local street intersecting a collector roadway to align or offset a minimum of 330-feet from any other street (measured centerline to centerline). Local Offset Policy: 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). 17 Centerville Subdivision MPP20-0018/ H-2021-0046 c. Applicant’s Proposal: The applicant has proposed to construct a collectorl road, Hill Park Street, to intersect Hillsdale Avenue, a collector road, so that it aligns centerline to centerline with Hill Park Street on the west side of Hillsdale Avenue. The applicant has proposed to construct one local road, Amorita Avenue, to intersect Amity Road, located 970-feet east of Hillsdale Avenue so that it aligns with the Amorita Avenue on the north side of Amity Road that will be construct in the future as part of Shelburne South Subdivision. d. Staff Comments/Recommendations: The applicant’s proposal meets District Policy and should be approved, as proposed. 9. Driveways 9.1 Amity Road a. Existing Conditions: There are 2 existing partially paved driveways from the site onto Amity Road: • A 12-foot wide driveway located 250-feet east of Hillsdale Avenue, and • An 18-foot wide driveway located 353-feet east of Hillsdale Avenue. b. Policy: Access Points Policy: District Policy 7205.4.1 states that all access points associated with development applications shall be determined in accordance with the policies in this section and Section 7202. Access points shall be reviewed only for a development application that is being considered by the lead land use agency. Approved access points may be relocated and/or restricted in the future if the land use intensifies, changes, or the property redevelops. Access Policy: District policy 7205.4.6 states that direct access to minor arterials is typically prohibited. If a property has frontage on more than one street, access shall be taken from the street having the lesser functional classification. If it is necessary to take access to the higher classified street due to a lack of frontage, the minimum allowable spacing shall be based on Table 1a under District policy 7205.4.6, unless a waiver for the access point has been approved by the District Commission. Driveway Location Policy: District policy 7205.4.5 requires driveways located on minor arterial roadways from a signalized intersection with a single left turn lane shall be located a minimum of 330-feet from the nearest intersection for a right-in/right-out only driveway and a minimum of 660-feet from the intersection for a full-movement driveway. District policy 7205.4.5 requires driveways located on minor arterial roadways from a signalized intersection with a dual left turn lane shall be located a minimum of 330-feet from the nearest intersection for a right-in/right-out only driveway and a minimum of 710-feet from the intersection for a full-movement driveway. Successive Driveways: District policy 7205.4.6 Table 1a, requires driveways located on minor arterial roadways with a speed limit of 50 MPH to align or offset a minimum of 425-feet from any existing or proposed driveway. Driveway Width Policy: District policy 7205.4.8 restricts high-volume driveways (100 VTD or more) to a maximum width of 36-feet and low-volume driveways (less than 100 VTD) to a maximum width of 30-feet. Curb return type driveways with 30-foot radii will be required for high- volume driveways with 100 VTD or more. Curb return type driveways with 15-foot radii will be required for low-volume driveways with less than 100 VTD. Driveway Paving Policy: Graveled driveways abutting public streets create maintenance problems due to gravel being tracked onto the roadway. In accordance with District policy, 7205.4.8, the applicant should be required to pave the driveway its full width and at least 30- 18 Centerville Subdivision MPP20-0018/ H-2021-0046 feet into the site beyond the edge of pavement of the roadway and install pavement tapers in accordance with Table 2 under District Policy 7205.4.8. Cross Access Easements/Shared Access Policy: District Policy 7202.4.1 states that cross access utilizes a single vehicular connection that serves two or more adjoining lots or parcels so that the driver does not need to re-enter the public street system. c. Applicant’s Proposal: The applicant has proposed to close the 2 existing driveways from the site onto Amity Road with the sidewalk or a multi-use pathway. d. Staff Comments/Recommendations: The applicant’s proposal meets District Policy and should be approved, as proposed. 9.2 Hill Park Street a. Existing Conditions: There are no existing collector roads within the site. b. Policy: Access Policy: District Policy 7205.4.1 states that all access points associated with development applications shall be determined in accordance with the policies in this section and Section 7202. Access points shall be reviewed only for a development application that is being considered by the lead land use agency. Approved access points may be relocated and/or restricted in the future if the land use intensifies, changes, or the property redevelops. District Policy 7206.1 states that the primary function of a collector is to intercept traffic from the local street system and carry that traffic to the nearest arterial. A secondary function is to service adjacent property. Access will be limited or controlled. Collectors may also be designated at bicycle and bus routes. Driveway Location Policy (Stop Controlled Intersection): District policy 7206.4.4 requires driveways located on collector roadways near a STOP controlled intersection to be located outside of the area of influence; OR a minimum of 150-feet from the intersection, whichever is greater. Dimensions shall be measured from the centerline of the intersection to the centerline of the driveway. Successive Driveways: District policy 7206.4.5 Table 1, requires driveways located on collector roadways with a speed limit of 25 MPH and daily traffic volumes greater than 100 VTD to align or offset a minimum of 245-feet from any existing or proposed driveway. Driveway Width Policy: District policy 7206.4.6 restricts high-volume driveways (100 VTD or more) to a maximum width of 36-feet and low-volume driveways (less than 100 VTD) to a maximum width of 30-feet. Curb return type driveways with 30-foot radii will be required for high- volume driveways with 100 VTD or more. Curb return type driveways with 15-foot radii will be required for low-volume driveways with less than 100 VTD. Driveway Paving Policy: Graveled driveways abutting public streets create maintenance problems due to gravel being tracked onto the roadway. In accordance with District policy, 7206.4.6, the applicant should be required to pave the driveway its full width and at least 30- feet into the site beyond the edge of pavement of the roadway and install pavement tapers in accordance with Table 2 under District Policy 7206.4.6. c. Applicant’s Proposal: The applicant has proposed to construct four driveways onto Hill Park Street to access the commercial and multi-family: • Two 25-foot wide curb return type driveways on the north and south side of Hill Park Street, located 188-feet east of Hillsdale Avenue and restrict both driveways to right-in/right-out only with a raised median, and 19 Centerville Subdivision MPP20-0018/ H-2021-0046 • Two 25-foot wide curb return type driveways on the north and south side of Hill Park Street located 176-feet east of the western driveways and 138-feet west of Odell Way. d. Staff Comments/Recommendations: The applicant’s proposal for the width of the driveways and curb return type driveways meets District Policy. The applicant’s proposal for the driveway locations do not meet District Policy which requires driveways with more than 100 VTD on collector roads with a 25 MPH speed limit to be offset a minimum of 245-feet from any other driveway or that driveways be offset a minimum of 150-feet from a public road intersection. However, staff recommends a modification of Policy due to the fact that the Meridian Fire Department has concerns about the drive aisle length without the additional access points for the east and west drive aisles on Hill Park Street, it is necessary for the site circulation to help separate the day care drop-off and pick-up traffic from the multi-family uses and the applicant has restricted the western driveways to right-in/right-out only to eliminate conflicting left-turn movements between driveways. This is a 28% modification of Policy for driveway spacing on collector roads and 8% modification of Policy for driveway spacing from a public intersection on collector roads, respectively, and can be approved at the Development Services Manager level. 9.3 Internal Local Streets a. Existing Conditions: There are no roadways within the site. b. Policy: Driveway Location Policy: District policy 7207.4.1 requires driveways near intersections to be located a minimum of 75-feet (measured centerline-to-centerline) from the nearest local street intersection, and 150-feet from the nearest collector or arterial street intersection. Successive Driveways: District Policy 7207.4.1 states that successive driveways away from an intersection shall have no minimum spacing requirements for access points along a local street, but the District does encourage shared access points where appropriate. Driveway Width Policy: District policy 7207.4.3 states that where vertical curbs are required, residential driveways shall be restricted to a maximum width of 20-feet and may be constructed as curb-cut type driveways. Driveway Paving Policy: Graveled driveways abutting public streets create maintenance problems due to gravel being tracked onto the roadway. In accordance with District policy, 7207.4.3, the applicant should be required to pave the driveway its full width and at least 30-feet into the site beyond the edge of pavement of the roadway. c. Applicant’s Proposal: The applicant has proposed to construct one driveway onto Odell Way to access the multi-family approximately 35-feet north of Hillsborough Street (measured centerline to centerline). d. Staff Comments/Recommendations: The applicant’s proposal to offset multi-family driveway on Odell Way 35-feet north of Hillsborough Street does not meet District Policy and should not be approved, as proposed. District Policy requires driveways near local road intersections to align or offset a minimum of 75-feet from a local road intersection. Staff has concerns about the left-turn movements out of this driveway and the visibility of westbound vehicles on Hillsborough Street. The applicant should be required to align with or offset the driveway a minimum of 75-feet from Hillsborough Street. 20 Centerville Subdivision MPP20-0018/ H-2021-0046 10. Traffic Calming a. Speed Control and Traffic Calming Policy: District policy 7207.3.7 states that the design of local street systems should discourage excessive speeds by using passive design elements. If the design or layout of a development is anticipated to necessitate future traffic calming implementation by the District, or the streets extend greater than 750-feet in length, then the District will require changes to the layout and/or the addition of passive design elements such as horizontal curves, bulb-outs, chokers, etc. The District will also consider texture changes to the roadway surface (i.e. stamped concrete) as a passive design element. These alternative methods may require maintenance and/or license agreement. b. Staff Comments/Recommendations: Beachfield Avenue and Odell Way are local roads that are proposed to have straight segments longer than 750-feet within the development. The applicant should be required to redesign the roadways or provide passive traffic calming measures consistent with District Policy. Stop signs, speed humps and valley gutters will not be accepted as traffic calming. 11. 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 III trees may be allowed in planters with a minimum width of 10-feet. 12. 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. 13.
