Lead Agency: City of Meridian Site address: North of Rolling Hill Drive and Overland Road Vicinity Map Staff Approval: January 10, 2022 Applicant: Josh Beach Brighton Development, Inc. 2929 W. Navigator Drive, Suite 400 Meridian, ID 83642 w r Representative: Same as above y Staff Contact: Paige Bankhead, E.I. Phone: 387-6293 E-mail: pbankheadCcDachdidaho.org A. Findings of Fact 1. Description of Application: This is a preliminary plat application for 2 multi-family lots and 6 commercial lots on 29.7 acres and a conditional use permit application for a 396 unit multi-family development within the site on 15.94 acres. The City of Meridian's Future Land Use Map designates this area as Mixed Use Regional. 2. Description of Adjacent Surrounding Area: Direction I Land Use Zoning North 1-84 NA South General Retail and Service Commercial District C-G East Residential Ada Count R1 West General Retail and Service Commercial District C-G 3. Site History: ACHD previously reviewed a small eastern portion of this site as part of Rackham Subdivision in July 2019. The requirements of this staff report for that small portion are consistent with those of the prior action. 4. Adjacent Development: The following developments are pending or underway in the vicinity of the site: 1 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 • Rackham Subdivision, a 20-lot mixed use subdivision with hotel, office buildings, restaurants and residential uses on 52 acres located directly west of the site and approved by ACHD on July 18, 2019. ej Site Site Location- Eagle View Landing Phase 2 (Rackham East Subdivision) located east of Rackham Subdivision (Original 52 acres) 5. Transit: Transit services are available to serve this site approximately % mile south of the site on Overland Road via route 29. 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 0.0 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): • The intersection of Overland Road and Eagle Road is scheduled in the CIP to be widened to 7-lanes on the north and south legs, and 8-lanes on the east and west legs, and reconstructed/signalized in the future. The design year is listed as 2025 in the IFYWP and the is listed to be improved between 2031 and 2035. • Overland Road is listed in the CIP to be widened to 7-lanes from Eagle Road to Cloverdale Road between 2036 and 2040 and is listed as unfunded. 2 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 • The intersection of Cloverdale Road and Overland Road is listed in the CIP to be widened to 7-lanes on the north and south legs and 8 lanes on the east and west legs and signalized between 2026 and 2030. 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 Overland Road as Level 2 facilities that will be constructed as part of a future ACHD project. B. Traffic Findings for Consideration 1. Trip Generation: This development is estimated to generate 4,626 total additional vehicle trips per day (114 existing); 432 total additional vehicle trips per hour in the PM peak hour (12 existing), based on the traffic impact study. 2. Traffic Impact Study Fehr & Peers prepared a traffic impact study for the proposed Eagle View Landing Phase 2 development. An executive summary of the findings as presented by Fehr& Peers can be found in Attachment 3. The following 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.

Mitigation/Required Improvements a. Policy: 3 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 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. • 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: The study shows that all intersections and roadway segments operate acceptably, except for the following that are discussed below. All road segments are projected to meet ACHD's acceptable level of service (LOS) thresholds for a 5-lanes principal arterial road under all conditions, except for during the PM peak hour for the segment of Overland Road between Eagle Road and Silverstone Way and Rolling Hill Drive under the 2023 total traffic conditions. Overland Road — Eagle Road to Silverstone Way This segment of Overland Road is listed in the CIP to be widened to 7-lanes between 2026 and 2030, and the site traffic is projected to be approximately 9.6% of the total 2023 traffic on 4 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 the segment. Therefore, staff does not recommend that the applicant be required to widen this segment consistent with District policy 7106.7.3 Alternative Mitigation Measures, which states, if an impacted roadway segment or intersection are programmed as funded in the IFYWP, or the CIP; no mitigation is required; and the District's Level of Service Planning Thresholds Policy, which states that 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. Rolling Hill Drive The applicant has proposed to vacate Rolling Hill Drive within the site, north of the site's south property line. The study reports the average daily traffic (ADT) for Rolling Hill Drive is projected to be 2,500 trips with all phases of the development in 2023, and approximately 1,200 for Phases 1 and 2, which consists of 396 apartment units. The phasing plan is shown below in the shaded regions. ter . Way Rolling Hills Drive Eared Rcao LEGEND Prom Phew 1 ■ Projod Phase 2 vroJen Phase) vrepck EmerrLKmn Eagle YiGw Landirqt Phme l Project l.dtabar. i ACHD does not set level of service thresholds for local roads, however, District Policy states that the ADT for local roads shall be less than 2,000. Staff does not recommend that Rolling Hill Drive be reclassified as a collector road or a commercial road to accommodate the traffic from all phases of the development due to the fact that there are several existing single family residential homes that will remain on Rolling Hill Drive to the south of the site and staff has concerns about the significant increase in traffic on an existing local road that will continue to serve single family homes after the development is completed. Therefore, staff recommends that the applicant should be restricted to phases 1 and 2 of the development for the 396 apartment units, and not be allowed to construct the offices proposed for phase 3 of the development until the existing residential homes on Rolling Hill Drive are purchased and the properties annexed into the City of Meridian with commercial or mixed use zoning. ACHD may consider reclassifying Rolling Hills Drive as a collector or commercial road at that time. In addition, staff recommends that Rolling Hill Drive be restricted to right-in/right-out only at Overland Road, consistent with the findings of the traffic impact study, which are discussed below. 5 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 Overland Road/Rolling Hill Drive The study recommends restricting the intersection of Overland Road/Rolling Hill Drive to right- in/right-out with phase 2 in 2022, or when the site generates 45 PM peak hour trips. The applicant should be required to restrict the intersection to right-in/right-out only with a 6-inch raised candles/median with the first phase of the development prior to ACHD's signature on the first final plat and after the private road, Rackham Way, is completed from Silverstone Way to the Rolling Hill Drive. The applicant should be required to provide a public access easement over the private road, Rackham Way. Rolling Hill Drive aligns with an existing driveway on Overland Road for the Movado Green Subdivision apartments on the south side of Overland Road. As part of ACHD's action on Movado Greens Subdivision,ACHD approved this driveway as a temporary full access driveway and indicated that this driveway could be restricted to right-in/right-out at any time in the future. The study recommends the construction of a westbound right turn lane on Overland Road at Rolling Hill Drive in 2023 with phase 3. However, there is not enough existing right-of-way for the applicant to construct a westbound right-turn lane on Overland Road at Rolling Hill Drive and it is not typical for ACHD to require a right-turn lane for a 5-lane principal arterial road. Therefore, staff does not recommend that the applicant be required to construct the westbound right-turn lane with this development application. Due to concerns from the residents on Rolling Hill Drive about additional traffic from the Rackham East Subdivision and the Rackham West Subdivision using Rolling Hill Drive when Rackham East Subdivision connects to Rolling Hill Drive, and that the daily trips on Rolling Hill Drive at the full build out of the development will exceed ACHD's thresholds for the ADT on local roads, the applicant has also proposed to restrict the site's access to Rolling Hill Drive to emergency access only. This would direct all traffic from Rackham East Subdivision to the Silverstone Way/Overland Road intersection to access Overland Road. Therefore, prior to the submittal of any construction plans for the development, the applicant should be required to submit an updated analysis to staff for the intersection of Silverstone Way/Overland Road for Phases 1 and 2 under the 2022 conditions, and for the final buildout under the 2023 conditions, and the estimated ADT and peak hour trips on Silverstone Way with Phases 1 and under the 2022 conditions and all Phases under the 2023 conditions. Staff will evaluate if restricting the site's access onto Rolling Hill Drive to emergency access only is feasible based on the updated analysis. If staff finds that restricting Rolling Hill Drive to emergency access only is acceptable, then no additional improvements are required to Rolling Hill Drive. Rolling Hill Drive/Private road, Rackham Way The study shows that a mini-roundabout will operate acceptably at the terminus of Rolling Hill Drive where it will intersect the private road, Rackham Way. The applicant will be required to construct a mini-roundabout at the terminus of Rolling Hill Drive, see Finding 3. Eagle Road/Overland Road The study shows that the intersection of Eagle Road/Overland Road exceeds ACHD's acceptable LOS thresholds under the existing and future conditions in the AM and PM peak hours. The study recommends the following improvements with the associated phase/year: • Add 1 northbound through lane for a total of 3 northbound through lanes (existing) • Add 1 northbound right-turn storage lane to separate the right-turn movements from the through movements (existing) • Restripe the southbound left-turn lanes to increase the total storage length to 500-feet for existing and 600-feet for 2021 conditions • Add 1 westbound right-turn lane for a total of 2 westbound right-turn lanes (existing) 6 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 • Add 1 westbound left-turn lane for a total of 2 westbound left-turn lanes (2023) However, the intersection is projected to exceed acceptable LOS thresholds in the PM peak hour under all conditions and the AM peak hour in the 2023 background and 2023 total traffic conditions even with these improvements. In addition, these improvements are not feasible as there is not enough existing right-of-way to improve the intersection with additional lanes and the site traffic at this intersection is projected to be 4.8% of the 2023 total traffic conditions. This intersection is also listed in the CIP to be widened to 7-lanes on the north and south legs and 8-lanes on the east and west legs with a design year of 2025 in the IFYWP and improved between 2031 and 2035. Therefore, staff does not recommend that the recommended mitigation be constructed with this development application consistent with the District's Alternative Mitigation Measures Policy and the District's Level of Service Planning Thresholds Policy stated above. Overland Road/Silverstone Way The intersection of Overland Road/Silverstone Way exceeds ACHD LOS thresholds under the existing conditions, and thus the future build out conditions. The study recommends the following mitigation with the associated phase/year: • Add 1 eastbound right-turn lane (existing) • Add 1 westbound right-turn lane (existing) • Add 1 eastbound left-turn lane (2021) for a total of 2 eastbound left-turn lanes o Convert signal phasing to only allow protected left-turns • Add 1 southbound right-turn overlap signal timing phase with updated signal splits (2021) • Add a southbound right-turn lane for a total of 2 southbound right-turn lanes (2022) Even with the recommended mitigation, the intersection of Overland Road/Silverstone Way is still projected to exceed ACHD LOS thresholds with the 2022 and 2023 total traffic conditions. As part of ACHD's action on Rackham Subdivision in 2019, that applicant was required to construct an additional southbound left-turn lane for a total of 2 southbound left-turn lanes. This was completed earlier this year. Staff is not supportive of the proposal to install an additional southbound right turn lane to create dual right turn lanes, as this is not ACHD's standard practice and will not be approved. In addition, there is not enough right-of-way on Overland Road to accommodate the construction of eastbound dual left turn lanes or the recommended westbound and eastbound right-turn lanes, making these improvements infeasible. Therefore, staff does not recommend any additional improvements to the intersection of Overland Road/Silverstone Way with this development application. Eagle Road and 1-84 Ramps Eagle Road north of the eastbound 1-84 off ramp and the 1-84 eastbound and westbound ramps are under the jurisdiction of the Idaho Transportation Department (ITD). The applicant, City of Meridian, and ITD should work together to determine if additional right-of-way or improvements are necessary on Eagle Road abutting the site or the 1-84 eastbound and westbound ramps. 7 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 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 Overland Road from Eagle Road to Silverstone Way was 29,000 on 6/15/2021. • The average daily traffic count for Overland Road from Silverstone Way to Rolling Hill Drive was 20,775 on 10/21/2020. • The average daily traffic count for Silverstone Way from Rackham Way to Overland Road was 6,600 on 10/21/2020. • The average daily traffic count for Rolling Hill Drive north of Overland Road was 200 on 10/21/2020. • The average daily traffic count for Rackham Way from Silverstone Way to the site was 400 on 10/21/2020. C. Findings for Consideration 1. Overland Road/Rolling Hill Drive The study recommends restricting the intersection of Overland Road/Rolling Hill Drive to right- in/right-out only with phase 2 in 2022, or when the site generates 45 PM peak hour trips. The applicant should be required to restrict the intersection to right-in/right-out with a 6-inch raised candles/median with the first phase of the development prior to ACHD's final approval of the first final plat and after the private road, Rackham Way, is completed from Silverstone Way to the 8 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 Rolling Hill Drive. The applicant should be required to provide a public access easement over the private road, Rackham Way. Rolling Hill Drive aligns with an existing driveway on the south side of Overland Road for the Movado Green Subdivision apartments. As part of ACHD's action on Movado Greens Subdivision, ACHD approved this driveway as a temporary full access driveway and indicated that this driveway could be restricted to right-in/right-out at any time in the future. This is consistent with ACHD's action on access management on Overland Road with new developments on Overland Road. Currently, Silverstone Way is signalized on Overland Road and the Movado Way/Overland Road intersection will be evaluated for signal warrants with the future development north of Overland Road. 10 itiyxr5tfi' " �r .•�• - i'. � L�., — - .. --_-W=Ci,i irwoa�d�Dr. t a. - II y— .. r[ F-View•" -.--'�`i.---: _� a� du. cir � ---- T ' d E Overland-R - _' .—� •p _ --a ` _ 7 Traffic Signal s Eimrantu g RIRO .� �� .i" �•�o i.F3lurlerry � � _ I f Access on Overland Road If Rolling Hill Drive will be restricted to emergency access only for the site as determined by ACHD, then the applicant is not required to restrict the intersection of Rolling Hill Drive/Overland Road right- in/right-out only. 2. Rolling Hill Drive a. Existing Conditions: Rolling Hill Drive is improved with approximately 24-25 of pavement and no curb, gutter or sidewalk within the site and to the south of the site. There is 50-feet of right- of-way for Rolling Hill Drive (25-feet from centerline). b. Policy: Off-Site Streets Policy: District Policy 7206.2.3 states that if the proposed development is not served by a public street that is fully improved to urban standards (curb, gutter, sidewalk) or a minimum 30-feet of pavement, then the developer shall provide 30-feet of pavement with 3-foot wide gravel shoulders from the site to the public street specified by the District; OR the developer shall provide 24-feet of pavement with 3-foot wide gravel shoulders and a minimum 6-foot wide detached asphalt/concrete pedestrian facility, from the site to a public street specified by the District. Alternatives to pavement widening including sidewalks and pathways or other proposals, may be considered by the District. The extent of roadway improvements (improvement type and length) will be determined by evaluating certain criteria. Criteria to establish improvement type and length include but are limited to: traffic volumes (existing and projected); number of pedestrians (existing and projected); location of pedestrian "attractors" and "generators" (i.e. parks and schools); number of access points/streets serving the proposed development; usable right-of-way; need for traffic calming; utilities and irrigation facilities. All utility relocation costs associated with the off-site street widening shall be borne by the developer. 9 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 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 island. The pavement width shall be sufficient to allow the turning around of a standard AASHTO SU design vehicle without backing. The developer shall provide written approval from the appropriate fire department for this design element. The District will consider alternatives to the standard cul-de-sac turnaround on a case-by-case basis. This will be based on turning area, drainage, maintenance considerations and the written approval of the agency providing emergency fire service for the area where the development is located. c. Applicant Proposal: The applicant has proposed to vacate Rolling Hill Drive north of the site's south property line as shown below in yellow in order to construct the development and an internal private road network. The applicant has proposed to provide a permanent right-of-way easement for a turnaround at the terminus of Rolling Hill Drive where it intersects the private road, Rackham Way, within the site. However, a turnaround is not shown on the site plan at this location. _FB Interstate $4 FS y r� - _ Proposed vacation of Rolling Hill Drive in yellow 10 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 `L FUTURE ACHD TURNAROUND EASEMENT FOR ROLLING HILLS OR. 8` PVC INSTALL SANITARY e„ PVC rSEWER MANHOLE SANITARY f NHOLE SSMH 7 EXISTING RIM:2670.88 PRESSURE IRRIGATION RRIGATION MAIN INV IN:2555.77 9" PVC INV 4UT:2655.67 8' PVC 671 6 d71 1�5�1 UPI —ry rya SSIAH Top i°P -RIM:2671.75 �dmai� INV IN2655.14 8' PVC RIGATION MANHOLE INV OUT:2555.03 S" PVC EXISTING PIPE INSTALL SANITARY o I SEWER NMHOLE x Z ROLLING HILL SUBDIVISION I I I d. Staff Comments/Recommendations: The vacation of Rolling Hill Drive north of the private road requires a separate application and has its own approval process. The applicant should be required to vacate Rolling Hill Drive prior to ACHD's signature on the first final plat. The applicant's proposal to provide a turnaround easement at the terminus Rolling Hill Drive does not meet District Policy and is not approved, as proposed. The applicant should be required to construct a mini-roundabout where Rolling Hill Drive and the private road, Rackham Way, are proposed to intersect similar to the mini-roundabout at Silverstone Way and the private road, Rackham Way, directly west of the site that was constructed with Rackham Subdivision. See Finding 3. The applicant should be required to improve the off-site portion of Rolling Hill Drive with 24- feet of pavement, 3-foot wide gravel shoulders and a 6-foot wide detached concrete sidewalk on one side of the road within the existing right-of-way. The study reports the average daily traffic (ADT) for Rolling Hill Drive is projected to be 2,500 trips under the 2023 total traffic conditions with all 3 phases, and approximately 1,200 for Phases 1 and 2, which accounts for the traffic from the 396 apartment units. Phases 1, 2 and 3 are shown in the shaded regions below. ACHD does not set level of service thresholds for local roads, however, District Policy states that the ADT for local roads shall typically be less than 2,000. Staff does not recommend that Rolling Hill Drive be reclassified as a collector or commercial road to accommodate the traffic from all phases of the development because are several existing single family residential homes that will remain on Rolling Hill Drive to the south of the site and staff has concerns about the significant increase in traffic on an existing local road that will continue to serve single family homes. Therefore, staff recommends that the applicant be restricted to phases 1 and 2 with this development and should not be allowed to construct the offices proposed for phase 3 of the development until the existing residential homes on Rolling Hill Drive are purchased and the properties annexed into the City of Meridian with commercial or mixed use zoning. 11 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 . r �r} f Site Vay t _ FioMg Hills Drive rt nd Road LEGEND Prnjer.t Phase 1 ■ Prnjed Phase 2 _— Ar. .. ❑ Project Pha3C 3 PrnjeR Inter Lion Eagle View Lending Phase 1 Project Lacatjan If ACHD determines that it is acceptable for the site to use Rolling Hill Drive as emergency access only, then the off-site improvements for Rolling Hill Drive and the construction of the mini-roundabout at the terminus of Rolling Hill Drive are not required and the applicant will be required to construct a standard cul-de-sac at the terminus of Rolling Hill Drive. 3. Mini-Roundabout - Rolling Hill Drive/Private Road Rackham Way If the site will use Rolling Hill Drive as a full access, then the applicant should be required to construct a mini-roundabout at the terminus of Rolling Hill Drive at the private road, Rackham Way, and follow the guidance provided in NCHRP 672 and will need to design the mini roundabout meeting the standards ACHD's Roundabout Design Guide policy section 5188. 4. Private Road — Rackham Way a. Private Road Policy: District policy 7212.1 states that the lead land use agencies in Ada County establish the requirements for private streets. The District retains authority and will review the proposed intersection of a private and public street for compliance with District intersection policies and standards. The private road should have the following requirements: • Designed to discourage through traffic between two public streets, • Graded to drain away from the public street intersection, and • If a private road is gated, the gate or keypad (if applicable) shall be located a minimum of 50-feet from the near edge of the intersection and a turnaround shall be provided. 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. 12 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 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. b. Applicant Proposal: The applicant has proposed to continue a private road, Rackham Way, from the west to intersect the terminus of Rolling Hill Drive at the site's south property line. c. Staff Comments/Recommendations: The applicant's proposal for the private road meets District Policy with the construction of the mini-roundabout as stated in Findings 2 and 3. If the City of Meridian approves the private road, the applicant shall be required to pave the private roadway its full width and at least 30-feet into the site beyond the edge of pavement of all public streets and install pavement tapers with 15-foot curb radii abutting the existing roadway edge. If private roads are not approved by the City of Meridian, the applicant will be required to revise and resubmit the preliminary plat to provide public standard local streets in these locations. Street name signs are required for the private road. The signs may be ordered through the District. Verification of the correct, approved name of the road is required. ACHD does not make any assurances that the private road, which is a part of this application, will be accepted as a public road if such a request is made in the future. Substantial redesign and reconstruction costs may be necessary in order to qualify this road for public ownership and maintenance. The following requirements must be met if the applicant wishes to dedicate the roadway to ACHD: • Dedicate a minimum of 50-feet of right-of-way for the road. • Construct the roadway to the minimum ACHD requirements. • Construct a stub street to the surrounding parcels. 5. Traffic Calming a. Speed Control and Traffic Calming Policy (Local): 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: There will be approximately 14 residential homes remaining on Rolling Hill Drive after the northern segment of Rolling Hill Drive is vacated for the development of the site. Due to the increase in traffic with phases 1 and 2, the applicant should be required to construct passive traffic calming measures on the off-site segment of Rolling Hill Drive consistent with District Policy with the first phase of the development. The construction plans for the passive traffic calming shall be submitted to ACHD with the first set of construction plans. If Rolling Hill Drive will be restricted to emergency access only for the site as determined by ACHD, then the applicant is not required to improve Rolling Hill Drive with traffic calming measures. 6. Bridge for Five Mile Creek There is 6-inch corrugated metal pipe with a smaller older metal pipe next to it, structure #1218, that crosses Five Mile Creek on Rolling Hill Drive just south of View Circle, circled in yellow below. The pipe has significant corrosion with deep pitting and thin sounding based on inspections by ACHD staff. This crossing is planned to be replaced by ACHD, however, the development is proposed to be ahead of ACHD's timeline to replace the structure. Staff has concerns about the 13 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 existing crossing's capacity for the construction traffic for the development and additional traffic before it is improved. Therefore, the applicant should be required to enter into a Cooperative Development Agreement (CDA) with ACHD to replace the crossing with the first phase of the development. The applicant will be reimbursed by ACHD for the crossing replacement and improvements. The District will require that the applicant submit the crossing plans for the crossing of the Five Mile Creek for review and approval prior to the pre-construction meeting and final plat approval. Note: all plan submittals for bridges or pipe crossings of irrigation facilities should be submitted to ACHD for review no later than December 15th for construction in the following year prior to irrigation season. If Rolling Hill Drive will be restricted to emergency access only for the site as determined by ACHD, then the applicant is not required to replace structure #1218. Site ' I �_�i�VeMile Creek E�Vi€'lur Or y - i' 4. 1 F Overland 1(d 7. Parking The applicant has proposed to provide 649 parking stalls to accommodate the residents and guests for 396 units for the proposed multi-family development, which is approximately 1.63 parking spaces per unit. Staff has concerns about the available parking for the multi-family in this development and the potential for overcrowded on-street parking on Rolling Hill Drive. 14 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 ACHD Traffic Services has received several complaints about overcrowded on-street parking in the City of Meridian with new apartment complexes. It appears that there are more tenants per apartment unit thus causing parking issues on adjacent public streets near apartment complex sites due to the lack of affordable housing in the Treasure Valley. Parking spots are not allowed to be striped on public roadways and on-street parking should not count towards the City's parking requirements as it can be removed any time at the discretion of ACHD. ACHD recommends that the City of Meridian require adequate on-site parking for the multi-family development, as well as with the future development of the commercial and office lots to the north of the multi-family development. If parking issues develop on Rolling Hill Drive in the future due to insufficient parking within the site for the development, staff recommends that the residents of Rolling Hill Drive contact ACHD traffic services to initiate an investigation to determine if No Parking signs are warranted on Rolling Hill Drive and the extents of the signage for No Parking on Rolling Hill Drive. 8. 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. 9. 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. D. Site Specific Conditions of Approval 1. If the applicant chooses to request to restrict the site's access to Rolling Hill Drive to emergency access only, then the applicant should be required to submit an updated operational analysis to staff for the intersection of Silverstone Way/Overland Road with the traffic from Phases 1 and 2 of the development under the 2022 conditions and traffic from the full buildout under the 2023 conditions, and the estimated ADT and peak hour trips on Silverstone Way with Phases 1 and 2 under the 2022 conditions and all Phases under the 2023 conditions. ACHD will determine if restricting the site's access to Rolling Hill Drive to emergency access only will be acceptable based on the updated analysis and District Policy. a. If Rolling Hill Drive will be restricted to emergency access only, then the applicant shall be required to construct a cul-de-sac at the terminus of the street after the vacation of Rolling Hill Drive within their site is completed. 2. If the applicant chooses to not use Rolling Hill Drive as emergency access only, or ACHD determines that access to Rolling Hill Drive for the site is necessary based on the updated analysis, the applicant shall be required to restrict Rolling Hill Drive on Overland Road to right-in/right-out only with a 6-inch raised candles/median with the first phase of the development prior to ACHD's final approval on the first final plat and after the private road, Rackham Way, is completed from Silverstone Way to Rolling Hill Drive. Provide a public access easement over the private road, Rackham Way. The following is also required if Rolling Hill Drive will be used to access the site: 15 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 a.

Even with the above mitigations,the westbound 1-84 ramp,eastbound 1-84 ramp and the intersection at Eagle Road & Overland Road were observed to continue to operate with unacceptable V/C ratios- A separate ccmprehenslve study to determine further mltlgatlon at the 1-84 Interchange and the intersection of Eagle Road&Overland Road should be performed.Fehr&Peers anticipates that the study will likely recommend a reconfigured interchange and possibly an alternative intersection configuration at Eagle Road&Overland Road. 2021 Plus Project The 2021 Plus Project conditions included the addition of a NB/Si3 stop-controlled intersection at the project access intersection of Rackham Way & Rolling Hills Drive. The proposed roundabout that will provide access to the ICCU Plaza at Rackham Way&Silverstone Way is also included in all Plus Project conditlons analyses_ Due to the proposed connectlon to Rolling Hills Drive, and since the ICCU Plaza and Eagle View Landing developments are adjacent, some traffic from the ICCU Plaza development was assumed to divert from Rackham Way and Silverstone Way to Rolling Hills Drive in each Plus Project scenario. While the prevlously outlines Improve the network over the unmitigated network, the intersection at Overland Road&Silverstone Way was observed to operate at an unacceptable overall VIC ratio,but with no individually fail ing motements-5inee the intersection was observed to operate just beyond acceptable V/C ratio thresholds,and no Individual movements are falling,no additionaJ mltlgatlons are recommended forthis scenario. 2022 Background Gackgrourid traftic projections were developed for ZD22 by growing the existing volumes with the COMPA55 annual growth rates.The trip generation reported inthe ICCU Plaza_n5 for the first two phases of development ware also included in the background growth for the 2022 horimn year far this project as the first phase of the ICCU Plaza was anticipated to be completed by 2022. in additlon to the mitigations In the 2021 background oondlilon,the following rnitrgation is recommended; • Overland Road&Silverstone Way o Add southbound right-turn lane for a total of 2 southboond right-turn lanes, ■ Atotal of 158 sauthbound righttorn vehicIe3 per hourcan be added tothe PM peak period before this mitigation is required- 3 25 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 Even with the above rmrtigatlons,the westbound 1-84 ramp,eastbound 1-84 ramp,the Intersection at Eagle Road & Overland Road, and the intersection at Overland Road & Silverstone Way were observed to continue tooperatewith unacceptable V/Crysips-Asidefrom the separate comprehensive study of the 1- 84 interchange and the intersection of Eagle Road &Overland Road that was recommended previouSly, no further mitigations are recommended in this scenario- 2022 Plus Project Like the 2021 Plus Project scenario,the intersection of Overland Road&Rolling Hi11s Drive was analyzed as bath an existing full NB/5B stop-controlled intersection and as a right-in-right-out restricted intersection.Only the right-In-right-out con flguratlensoperated atacceptable LOSand V/C, Therefore,in addition to the same mitigations that were recornrnended in previous analyses in this report, the following recommendation i3 recommended within the study area: + Overland Road& Rolling Hills Drive o Convert the intersection to a RIROconfguretion, ■ A total of 45 sDuthbound left turn vehicles per hour can be added to the PM peak period before this mitigation is required- As mentioned previously, even with the above mitigations, the westbound 1-84 ramp, eastbound I-84 earnp, the intersection at Eagle Road & Overland Road, and the Intersection at Overland Road & Silverstone Way were observed to continue to operate with unacceptable VIC ratios. Aside from the separate comprehensive study of the 1-84 interchange and the intersection of Eagle Road&Overland Road that was recommended previously, no further mitigations are recommended in this scenario. 2028 Background Background traffic projections were developed for 2023 by growing the existing volumes with the COMPASS annual growth rates.It should be noted that while Phase 3 of the ll= Plaza is n-ot antiripated lobe completed by 2023,which is the horizon year for Phase 3 of the Eagle View Landing development, trlp generation From all three phases of the ICCU Plaza wero Included In the baCkground of this analysis to present a holistic understanding of the traffic demands once all three phases of both developments are completed- In addition to the improvements recommended in previous chapters of this analysis, the following recpmmendal ions are recommended within the study area- • Eagle Road&Overland Road o Add 1 westbound left-turn Ianefora total of 2 southbound left-turn lanes. ■ A total-of 127 eastbound through,6 eastbound right turn,and 84 westbound left turn vehicles per hour can be added to the PM peak period westbound left turn before this mItrgetion is repuIred. As mentioned previously, even with the above mitigations, the westbound 1-84 ramp, eastbound 1-84 ramp, the intersection at Eagle Road & Overland Road, and the intersection at Overland Road & Silverstone Way were observed to continue to operate with unacceptable VIC ratios- Notably, beginning in this scenario,the southbound left-turn queue at Eagle Road &Overland Road will likely no longer be accommodated by increasingthe storage length-Fehr&Peers recognizes that widening 100 26 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 the Intersection Is planned Fora future project. However,wlthouta reconflguratlon of the Intersectlorr at Eagle Road &Overland Road, it is likely that the 951h percentile sauthbound left-turning queue will spill back to the eastbound offramp intersection and impact operations there. Fehr & Peers recommends accelerating the pro€ens to evaluate and implement alternative intersection designs such as continuous flow intersection(CFI),through-U-turn intersection,etc.as part of the redesign of the intersection at Eagle Road&,Overland Readr tlke lse, Fehr & Peers recommends expediting the wldening of Eagle Road and Overland Road since acceptable V/C ratios and queues at that intersection cannot be achieved without either implementingthese widening projects or an alternative intersection configuration_ 2023 Plus Project The 2023 Plus Project conditions included the addition ofthe roundabout atthe project access at Rackham Way&Silverstona Way as well as the NR/58 stop-controlled intersection at Rackham Way&Rolling Hills Drive,The intersection of Overland Rood&Rolling Hills Drive was analyzed as both ari existing full NB/SB stop-controlled intersection and as a right-in-right-out restricted intersection.It was determined that the right-in-right-out rest rlcted Stop coin trol Is recommended for the 2023 Plus Profeetconditions- As per the results of the right turn lane analysis performed for this scenario,the fallowing mitigaoon is recommended within the study area: + Overland Road& Rolling Hills Drive o Add a westbound right-turn storage lane. * Overland Road From Eagle Road toSlIverstorre Way o Either advance the planned GIP project to widen Overland Road from a five-lane to severs-lane Bross section or implement sufficient TD M measures to reduce the total traffic demand by 35 vehicles per hour in the shoulder hour before the PM peak period. This mitigation is based on the results of the segment analysis. As mentioned previously, even with the previous mitigations, the westbound I-18 ramp and the intersection at Eagle Road&Overland Road were abserved to continue to operate with unacceptable V/C ratios and will require further study to evaluate alternative interchange and intersection 00rrfiguratian5 at those locations.Fehr&Peers does not recommend further widening of either of these locations before obtaining the resu Its frorn that study_ Also,while improved over tha unmitigated scan 2ria,the intersection 21Silvarstone Way&Overland Road was still observed to operate at unacceptable V/C ratlo In the eastbound left turn movement, Mitigating the failing movement beyond the listed recommendations would likely require extensive intersection reconfiguration,so no additiorrall mitigations are recommended forth-is scenario_ Project Contribution to Traffic Fehr&Peers compared the tripsgenerated bythe development at each intersection to the total trips at each intersection during the Plus Project Conditions analyses_Table E:5-00.3 outlines the percentage of traffic at each intersection that in generated by the development.Table E5-00-4 outlines the percentage of traffic at each study segment that is generated by the develaprnert. in 27 Rackham East Subdivision/Eagle View Apartments MPP21-0007/H-2021-0075 Table U-0&1:Project Trips as a Percent of Total Plus Project I ntersectlon Volume ID Location Period 2022 Plus 2022 Plus 2023 Plus Project Project Pt+o#ect 1 Eagle Road& AM 0.3% Q.4% 1.5% 1-84 WD Ramp PM 0-3% R.5% 1.3% 2 Eagle Road& AM 0.5% D.8% 2,3% 1-84 EB Ramp PM 0.6% 1.0% 2.6% 3 Eagle Road& AM 1.1% 1.7% 4.8% overland Road PM 1.1% 1.8% 4.4% 4 5ilverstone Way& AM 2_6% 4.0% 10.S% Overland Road PIN 2r5% 3.7% 8,6% S Overland Read & ANI 3,59b 5.2% 13.8% Rolling Hills Drive PM 3.0% 4,5% 10.6% 6 Rackham Way& AM 9.6% 10.4% 72.9% Silverswna Way PM 10.9% 12.1% 23.1% 7 Rackham Way& AM 48.9% 51.1% 72.2% Rolling Hills Drive PIA 49.1% 51.9% 703% SOU":Ft�-}r�I.Pen 2C2 1 Table ES-40-4; Project Trips as a Percent of Totai Plus Project Segment Volume Roadway Segment Period 2021 Plus 2022 Plus 2023 Plus Project Project Project Overland Road Eagle Road to AM 2.4% 3,7% 9,6% 5ilverstone Way PM 2.2% 3.3% 7.9% 5ilverstone Way to AM 2.7% 4.0% 10.9% Overland Road Rolling Hi115Drive PM 2.1% 12% 7.9% Rack ham way to AM 8.1% 10.7% 21,9% Silverstone Way Overland Road PM 6.5% 8.0% 1617% Rolling Hills Drive gland Road tea AM 38.9% 43.5% 66.8% N o rth End of Study Area PM 42.B% 46.8% 66.0% 5iiverstone Way to AM 7.7% 5.9% 8.1% Rackham Way North End-of Study Area PM 1.9% 23% 10.0% %nuree FeM1r&Peers 2021.
