ACHD Draft Report MPP21-0027 Tessera Ranch V1 Development Services Department Project/File: Tessera Ranch/ MPP21-0027/ H-2022-0020 This is an annexation with rezone and a preliminary plat application to allow for the development of 568 lots on 123-acres. Lead Agency: City of Meridian Site address: 4035 & 4185 S. Linder Road and S1226417350 & S1226417225 , Staff Approval: XXXX, 202X r Applicant: Patrick Connor Providence Properties, LLC 701 S. Allen Street, #104 � Meridian, ID 83642 Staff Contact: Dawn Battles, Planner Phone: 387-6218 ° E-mail: dbattles@achdidaho.org A. Findings of Fact 1. Description of Application: The applicant is requesting approval of annexation with rezone of 123 acres from RUT (Rural-Urban Transition) to residential zones R-2 (27-acres), R-4 (6-acres), R-8 (78-acres) and R-15 (17-acres) and a preliminary plat application to allow for the development of 568 lots consisting of 393 single family lots, 75 townhome lots, 5 common driveway lots and 45 common lots. The two existing homes and accessory structures are proposed to be removed. The applicant's rezone proposal is consistent with the City of Meridian's future land use map which designates this site as medium density residential. 2. Description of Adjacent Surrounding Area: Direction Land Use Zoning North Rural-Urban Transition Ada Count RUT South Rural-Urban Transition (Ada County) RUT East Medium Density Residential & Estate Residential/ Rural- R-4 & R1/ RUT Urban Transition (Ada County) West Rural-Urban Transition (Ada County) RUT 3. Site History: ACHD staff previously reviewed this site as MPP19-0022/ H-2020-0012 for Cedarbrook Subdivision in June 2020. The requirements of this staff report are updated to reflect the current proposed site plan. 4. Adjacent Development: The following developments are pending or underway in the vicinity of the site: 1 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 • Burnside Ridge Estates, a 299 lot development consisting of 275 single family lots and 24 common lots located directly adjacent to the north of the site and is currently under review by ACHD. 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 4.3 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): • Victory Road is scheduled in the IFYWP to be widened to 3-lanes from Linder Road to Meridian Road with the design year in 2026 and the construction date has not been determined. • Linder Road is listed in the CIP to be widened to 3-lanes from Victory Road to Amity Road between 2036 and 2040. • The intersection of Victory Road and Linder Road is listed in the CIP to be reconstructed as a single lane roundabout between 2036 and 2040. • The intersection of Amity Road and Linder Road is listed in the CIP to be reconstructed as a single-lane roundabout with a westbound right-turn bypass lane with 4-lanes on the north leg, 4-lanes on the south, 2-lanes on the east, and 2-lanes on the west leg between 2036 and 2040. • The intersection of Amity Road/SH-69 is listed in the CIP to be widened to 6-lanes on the north leg, 6-lanes on the south, 7-lanes on the east, and 7-lanes on the west leg and signalized between 2031 and 2035. 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 2 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 coordination and cooperation among local jurisdictions in implementing the Roadways to Bikeways Plan recommendations. The BMP identifies Linder Road and Amity Road as Level 3 facilities that will be constructed as part of a future ACHD project. The BMP also identifies level 1 facilities on the new collector roadways shown on the Master Street Map (MSM) within the site. The applicant will construct the new collector roadways consistent with the MSM and the Roadways to Bikeways Master plan. B. Traffic Findings for Consideration 1. Trip Generation: This development is estimated to generate 4,253 vehicle trips per day; 427 vehicle trips per hour in the PM peak hour, based on the traffic impact study. 2. Traffic Impact Study CR Engineering prepared a traffic impact study for the proposed (Burnside) Jackson Ridge Estates The executive summary of the findings as presented by CR Engineering can be found as Attachment 3. 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.

Roadway Segments i a C - 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. 3 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 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 TIS indicates all study area intersections are expected to operate at an acceptable level of service planning threshold in the AM and PM peak hours under existing traffic conditions except for the Victory Road/SH-69 intersection. The TIS also indicates that all roadway segments in the study area are expected to operate at an acceptable level of service planning threshold in the AM and PM peak hours under existing traffic, 2030 background traffic and 2030 total traffic conditions with the exception of Linder Road between Victory Road and Harris Street. Crash data of the study area intersections were analyzed between 2016 and 2020 and there were no concerns found with the exception of the Victory Road/SH-69 and Amity Road/SH-69 intersections with a crash rate (Crashes per MEV) of 1.02 and 0.93 and may require safety improvements. The TIS notes that a higher percentage of the crashes were on the SH-69 approaches. See safety improvements recommended in the TIS listed below under the specific intersections. The TIS recommends mitigation measures for the following intersections to mitigate existing traffic, 2030 background traffic and 2030 total traffic conditions and the following roadway 4 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 segment to mitigate 2030 total traffic conditions. The percentage of site generated traffic under 2030 total traffic conditions in the PM peak hour is provided in parenthesis. Intersections: • Victory Road/ SH-69 (2.5%) ■ Signal modifications to allow overlap signal phase on the westbound right-turn movements for existing traffic conditions in the AM peak hours ■ Install a northbound right-turn lane for existing traffic conditions in the AM peak hours ■ Convert to a conventional intersection with the following lanes for 2030 background traffic conditions o Eastbound approach: Existing lanes with one left-turn and one shared through/right-turn lanes o Westbound approach: Dual left-turn lanes, one through lane, and one right-turn lane o Northbound approach: One left-turn, two through lanes and a shared through/right-turn lane o Southbound approach: Dual left-turn lanes, two through lanes, and a shared through right-turn lane ■ Convert to a MUT with the following lanes for 2030 background traffic and 2030 total traffic conditions o Eastbound approach: Existing lanes with one left-turn and one shared through/right-turn lane o Westbound approach: Existing lanes with one left-turn, one through and one right-turn lane o Northbound approach: Three through lanes with an exclusive right-turn lane Construct a U-turn loon on SH-69 north of the intersection to accommodate northbound U-turn movements o Southbound approach: Three through lanes with an exclusive right-turn lane Construct a U-turn loon on SH-69 south of the intersection to accommodate southbound U-turn movements ■ Pay ITD a proportionate share for 2030 total traffic conditions This intersection is located offsite and is not programmed for improvements in ACHD's IFYWP or CIP. A shoulder hour analysis was performed in the AM peak hours and the shoulder volumes at the intersection listed above meets ACHD's acceptable Level of Service planning threshold during the AM shoulder hours. Consistent with ACHD's Alternative Mitigation Measures policy, the applicant submitted a shoulder hour analysis, and found that the intersection listed above is anticipated to operate at an acceptable Level of Service planning threshold during the shoulder hours. Under this policy if an intersection is expected to meet the minimum acceptable level of service planning 5 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 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. The applicant's traffic engineer submitted a Victory Road/SH-69 intersection alternative mitigation analysis, consistent with ACHD policy, as this intersection is not programmed in ACHD's IFYWP or CIP and the TIS states the installation of a northbound right-turn lane on SH-69 may be cost-prohibitive for an interim improvement due to the location of the existing signal pole located in the southeast corner of the intersection. The alternative mitigation analysis considered the following for existing traffic, 2030 background traffic and 2030 total traffic conditions: • Construct sidewalk connectivity to pedestrian ramps at the northwest corner of Victory Road and SH-69 intersection • Install a pedestrian crossing at the Victory Road and Stoddard Road intersection • Construct sidewalk to fill in the gaps on the east side of Meridian Road at the Ridenbaugh Canal bridge • Install safety improvements at the intersection as follows: ■ Near-side signal heads on the existing poles existing poles for the northbound/southbound through movements ■ Near-side signal heads on the back of the signal mast arms for the northbound/southbound left-turn movements ■ Far-side signal heads on the signal poles for the north bound/southbound left- turn movements ■ 3-inch yellow retroreflective sheeting to all existing signal backplates The TIS recommends that reconstructing the intersection as a MUT is consistent with the Meridian Corridor Plan and the potential crash reduction factor of the installation of signal visibility improvements is approximately 15% of all crash types. However, the Victory Road/SH-69 intersection is not programmed or funded in ACHD's CIP or ITD's transportation plan. Furthermore, the north bound/southbound approaches of this intersection are on SH-69 and under the jurisdiction of ITD. ITD is not requiring any mitigation improvements as part of this development application, see attachment 4. In addition, the proposed site traffic at this intersection will be less than 10% of the 2030 total traffic conditions. Therefore, consistent with District policy 7205.3.1 Level of Service Planning Threshold, which states, 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; no improvements are required at this intersection for the road segment that is within ACHD right-of-way. • Amity Road/SH-69 (2.4%) ■ Southbound through lane groups exceed ITD's threshold for 2030 background traffic and 2030 total traffic conditions The southbound through lane groups are on SH-69 and under the jurisdiction of ITD. ITD is not requiring any mitigation improvements as part of this development application, see attachment 4. • Victory Road/Linder Road (19.7%) 6 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 ■ Single lane roundabout or interim 3x3 traffic signal for 2030 total traffic conditions This intersection is located offsite and is listed in ACHD's CIP to be reconstructed as a single lane roundabout between 2036 and 2040. The intersection of Victory Road/Linder Road is anticipated to operate at an acceptable level of service planning threshold under 2025 total traffic conditions; however, the critical westbound movement at the intersection is expected to operate at LOS E in the PM peak hours. Because of this and consistent with ACHD policy, a signal warrant analysis was completed for this intersection. The intersection analysis found that the intersection meets the 8 and 4 peak hour warrants and requires a signal to accommodate the 2030 total traffic conditions when the site generates 244 PM peak hour trips, equivalent to 386 single family lots and 79 multi-family dwelling units. Consistent with ACHD's Alternative Mitigation Measures policy, the applicant submitted a shoulder hour analysis, and found that the intersection listed above is anticipated to operate at an acceptable Level of Service planning threshold during the shoulder hours. Under this policy if an intersection is expected to 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. The applicant's traffic engineer submitted a Victory Road/Linder Road intersection alternative mitigation analysis, consistent with ACHD policy, as the construction of a single lane roundabout and the installation of a traffic signal at this intersection is infeasible due to the constraints of the right-of-way, irrigation structures and the power pole on the west side of Linder Road. The alternative mitigation analysis considered the following for 2030 total traffic conditions: • Install pedestrian crossing on Victory Road at the Victory Road and Linder Road intersection • Install a pedestrian crossing on Victory Road at the Victory Road and Stoddard Road intersection • Construct missing sidewalk on Linder Road between Overland Road and Victory Road The analysis notes that a pedestrian crossing at the Victory Road/Linder Road or the Victory Road/Stoddard Road intersection may provide a benefit to the school children. However, a Pedestrian Hybrid Beacon (PHB) is required to be installed in close proximity to this intersection on Linder Road at American Fork Drive as part of the Blue Valley Elementary development located 3/4 miles north of the Linder Road/Victory Road intersection and there is an existing PHB installed on Stoddard Road at Kodiak Drive located less than one-half mile north of the Victory Road/Stoddard Road intersection. Additionally, sidewalk improvements may be infeasible along Linder Road between Overland Road and Victory Road due to the constraints of the right-of-way and large power poles. To verify the assumptions of the TIS and to ensure that improvements are made, when necessary, the applicant should be required to submit an updated intersection analysis for the Linder Road/Victory Road intersection prior to ACHD's approval of the final plat that contains the 38711 single family building lot. Staff will review the updated analysis and determine at that time what improvements may be required. Additional improvements may be required based on the findings of the updated traffic impact study. Roadway Segment: • Linder Road between Victory Road and Harris Street (25.6%) 7 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 ■ Widened to 3-lanes for 2030 total traffic conditions The roadway segment of Linder Road from Victory Road to Harris Street is located partially off-site. The TIS recommends this segment of Linder Road should be widened to 3-lanes to accommodate 2030 background traffic conditions with 360 PM peak hour trips. The roadway segment of Linder Road from Victory Road to Amity Road is listed in the CIP, as an unfunded project, to be widened to 3-lanes between 2036 and 2040. The TIS notes that a southbound left-turn lane is proposed on Linder Road at the proposed Harris Street/Linder Road intersection providing the three lanes needed to meet the planning level of service thresholds. A shoulder hour analysis was performed and the shoulder hour volumes on the segment listed above meets ACHD's acceptable Level of Service planning threshold for a 2-lane minor arterial roadway. Consistent with ACHD's Alternative Mitigation Measures policy, the applicant submitted a shoulder hour analysis, and found that the roadway segment listed above is anticipated to operate at an acceptable Level of Service planning threshold during the shoulder hour. Under this policy if a roadway segment is expected to 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. The applicant's traffic engineer submitted a Linder Road from Victory Road to Harris Street alternative mitigation analysis, consistent with ACHD policy, as this roadway segment is listed as an unfunded project in ACHD's CIP and the TIS also notes that widening Linder Road to 3- lanes from Victory Road to Harris Street may be infeasible due to the right-of-way constraints and existing utility infrastructure on the west side of Linder Road. The alternative mitigation analysis considered the following: • Construct missing sidewalk on this segment of Linder Road • Construct bicycle facilities on this segment of Linder Road • Construct missing sidewalk and/or bicycle facilities on Linder Road from north of Victory to Blue Valley Elementary School • Install pedestrian crossing on Victory Road at the Victory Road and Linder Road intersection • Install a pedestrian crossing on Victory Road at the Victory Road and Stoddard Road intersection The analysis notes that a pedestrian crossing at the Victory Road/Linder Road or the Victory Road/Stoddard Road intersection may provide benefit to the school children. However, a Pedestrian Hybrid Beacon (PHB) is required to be installed in close proximity to this intersection on Linder Road at American Fork Drive as part of the Blue Valley Elementary development located 3/4 miles north of the Linder Road/Victory Road intersection and there is an existing PHB installed on Stoddard Road at Kodiak Drive located less than one-half mile north of the Victory Road/Stoddard Road intersection. Additionally, sidewalk improvements and bicycle facilities may be infeasible along Linder Road from Victory Road and Harris Street and between Victory Road and Blue Valley Elementary due to the constraints of the right-of- way and large power poles. To verify the assumption of the TIS and to ensure that improvements are made, when necessary, the applicant should be required to submit an updated roadway segment analysis for Linder Road between Victory Road and Harris Street prior to ACHD's approval of the final plat that contains the 361s' single family building lot. Staff will review the updated analysis and 8 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 determine at that time what improvements may be required. Additional improvements may be required based on the findings of the updated traffic impact study. Turn Lanes: The TIS recommends modifications to the existing intersection turn lanes for 4 off site intersections included within the study area. The TIS specifically recommends extending the existing turn lanes to provide additional storage to mitigate the 2030 total traffic conditions. The percentage of site generated traffic under 2030 total traffic conditions in the PM peak hour is provided in parenthesis. • Overland Road/Linder Road ■ Extend the westbound left-turn lane an additional 75-feet (19%) ■ Extend the northbound right-turn lane an additional 250-feet (24%) This intersection is located offsite. The TIS notes that the westbound left-turn lane should be extended an additional 75-feet and can be accommodated on Overland Road at Linder Road within the existing center turn lane and the northbound right-turn lane should be extended an additional 250-feet will require additional right-of-way or realignment. Both turn lane extensions are warranted when the site generates 390 PM peak hour trips. This intersection is listed in ACHD's IFYWP to be widened to 5-lanes on the north leg, 5-lanes on the south, 6- lanes on the east, and 6-lanes on the west leg as part of the Linder Road widening project from Overland Road to Franklin Road. The design year is scheduled for 2022 and the construction date has not been determined. The applicant should be required to extend the westbound left-turn lane an additional 75-feet within the existing travel lane on Overland Road at Linder Road and extend the northbound right-turn lane on Linder Road at Overland Road to the extent that is allowable without causing conflict with the existing driveway located on the east side of Linder Road south of the Overland Road/Linder Road intersection prior to plan approval and ACHD's signature on the final plat that contains the 391 st building lot. Burnside Ridge Estates located directly adjacent to the north of the site has been required to extend the northbound right-turn lane on Linder Road at Overland Road an additional 250-feet prior to plan approval and ACHD's signature on the final plat that contains the 199' building lot. The turn lane should be constructed by the development that necessitates the improvement first. Compensation will not be provided for additional pavement widening. • Victory Road/Linder Road ■ Construct an eastbound left-turn lane with a minimum 25-feet of storage (0%) ■ Construct a westbound left-turn lane with a minimum 75-feet of storage (30%) ■ Construct a northbound left-turn lane with a minimum 50-feet of storage (50%) ■ Construct a southbound left-turn lane with a minimum 25-feet of storage (0%) This intersection is located offsite and is listed in ACHD's CIP to be reconstructed as a single lane roundabout between 2036 and 2040. The TIS notes the westbound left-turn lane on Victory Road is warranted to be constructed with a minimum 75-feet of storage and the northbound left-turn lane on Linder Road is warranted to be constructed with a minimum 50- feet of storage when the site generates 390 PM peak hour trips and is a feasible improvement. Therefore, the applicant should be required to construct a westbound left-turn lane on Victory Road at Linder Road with a minimum 75-feet of storage and a northbound left- turn lane on Linder Road at Victory Road with a minimum 50-feet of storage prior to plan approval and ACHD's signature on the final plat that contains the 391 st building lot. 9 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 The TIS notes that the eastbound left (Victory Road) and southbound left-turn (Linder Road) lane movements are not anticipated to have any site traffic. Therefore, consistent with District policy 7205.3.1 Level of Service Planning Threshold, which states, 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; no improvements are required. • Victory Road/SH-69 ■ Extend the eastbound left-turn lane an additional 85-feet (12%) ■ Extend the westbound left-turn lane an additional 200-feet (0%) ■ Extend the westbound right-turn lane an additional 275-feet (0%) ■ Construct a northbound right-turn lane and loon with a minimum 825-feet of storage (0%) ■ Construct a southbound right-turn lane and loon with a minimum 350-feet of storage (22%) • Amity Road/SH-69 ■ Extend the eastbound left-turn lane an additional 45-feet (21%) ■ Extend the westbound left-turn lane an additional 75-feet (0%) ■ Construct a westbound right-turn lane with a minimum 175-feet of storage (0%) ■ Construct a southbound right-turn lane with a minimum 75-feet of storage (28%) The extension of the existing turn lanes at the Victory Road/SH-69 intersection will require additional right-of-way or realignment for the eastbound left-turn lane, additional right-of-way and the existing sidewalks would be impacted for the westbound right-turn lane and the westbound left-turn lane could be extended within the existing center turn lane on Victory Road. Due to the additional right-of-way required (eastbound left and westbound left), the potential impacts to sidewalk, these improvements are infeasible, and no mitigation is recommended. In addition, the TIS notes the westbound right-turn movement (Victory Road) is not anticipated to have any site traffic. Therefore, consistent with District policy 7205.3.1 Level of Service Planning Threshold, which states, 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; no improvements are required at these intersections for the road segments that are within ACHD right-of-way. The extension of the existing turn lanes and the construction of the turn lanes at the Amity Road/SH-69 intersection will require additional right-of-way for the eastbound left, the westbound left and the westbound right-turn lanes. This intersection is listed in ACHD's CIP to be widened to 7-lanes on the east and west approaches and 6-lanes on the north and south approaches between 2031 and 2035. Therefore, consistent with the District's Alternative Mitigation Policy, which states that no alternative mitigation is required 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). The southbound right-turn lanes at both intersections and the northbound right-turn lane at Victory Road/SH-69 intersection are on SH-69 and are under the jurisdiction of Idaho Department of Transportation. Therefore, the applicant should work with the City of Meridian 10 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 and ITD to determine if additional improvements are necessary on SH-69 at these intersections. The TIS notes turn lanes are warranted at the following site access locations: • Linder Road/Harris Street o Southbound left-turn lane o Southbound right-turn lane • Linder Road/Site Access D o Northbound left-turn lane o Southbound right-turn lane Site Access Evaluation: • Site Access A, on the proposed Harris Street, a proposed collector street located 2,080-feet west of Linder Road and in alignment with the proposed collector street, Farmyard Avenue, as part of Burnside Ridge Estates located directly adjacent to the north. Turn lanes were not warranted at this access. The TIS notes this access is required to be constructed per the MSM, meets ACHD spacing requirement, does not meet the '/2 mile location between Ten Mile Road and Linder Road as shown on the MSM; however, it aligns with the shifted alignment proposed in the Burnside Ridge Estates, is needed to serve the site, and is anticipated to operate acceptable as a full access. Although the location does not meet District Roadway Offset policy, which requires a collector roadway to intersect a minor arterial at the half-mile, staff recommends approval of the proposed location to avoid the existing homes to the west and south of the site, it aligns with the proposed location in Burnside Ridge Estates located directly adjacent to the north, it allows for curvature in the road instead of a long straight roadway and it is anticipated to operate acceptably as a full access. • Site Access B, on the proposed Harris Street, a proposed local street located 660-feet east of Site Access A. Turn lanes were not warranted at this site access. The TIS notes this access meets spacing requirements, is needed to serve the site to help reduce traffic volumes on other internal local streets, reduce vehicle- pedestrian/bicycle conflicts within the residential areas, improve access and mobility for emergency and school bus services, removing this access will result in more local road segments exceeding 1,000 average daily trips and is anticipated to operate acceptably as a full access. Staff recommends approval of the location of the local street as it meets District policy. • Site Access C, on the proposed Harris Street, a proposed local street located 980-feet east of Site Access C. Turn lanes were not warranted at this site access. The TIS notes The TIS notes this access meets spacing requirements, is needed to serve the site to help reduce traffic volumes on other internal local streets, reduce vehicle- pedestrian/bicycle conflicts within the residential areas, improve access and mobility for emergency and school bus services, removing this access will result in more local road segments exceeding 1,000 average daily trips and is anticipated to operate acceptably as a full access. Staff recommends approval of the location of the local street as it meets District policy. • Harris Street access on Linder Road, a proposed collector street located 1,580-feet north of Site Access D. The TIS notes this access is needed to serve the site, is 11 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 required to be constructed per the MSM, exceeds the 555-feet sight distance requirement, and is anticipated to operate acceptably as a full unsignalized access. The TIS notes a southbound left-turn lane is warranted with off-site traffic generated by the proposed development on the east side of Linder Road across from the site to the northeast and a southbound right-turn lane is warranted when the site generates 110 PM peak hour trips. Additionally, the southbound right-turn lane is warranted under background traffic conditions with the construction of Burnside Ridge Estates located directly adjacent to the north. Staff recommends approval of the location as it meets District policy. Although, not recommended in the study, staff recommends the construction of a dedicated center left-turn lane and a dedicated right-turn lane when Harris Street is constructed to intersect Linder Road to minimize the impacts to through traffic. • Site Access D, on Linder Road, located 1,060-feet north of Amity Road. The TIS notes that this access should be constructed as a local roadway, as there is not a collector roadway shown in this location on the MSM, is needed to serve the site, exceeds the 555-feet sight distance requirement, and is anticipated to operate acceptably as a full access. Additionally, the TIS notes this roadway is anticipated to exceed 1,000 average daily traffic (ADT) but is less than 2,100 ADT, removing this access would create additional traffic to the proposed Harris Street which is estimated to exceed 5,050 ADT and ACHD policy allows a maximum ADT of 3,000 on a collector roadway and the eastbound lane group is not anticipated to operate at an acceptable level of service in the PM peak hour. The TIS notes a northbound left-turn lane is warranted when the site generates 290 PM peak hour trips and a southbound right-turn lane when the site generates 350 PM Peak hour trips. Although the MSM does not show a collector roadway in this location, the ADT exceeds District policy for a local street which should be less than 2,000 ADT; therefore, staff recommends the construction of a collector roadway in this location. The applicant should be required to construct a dedicated center left-turn lane and a dedicated southbound right-turn lane on Linder Road at Site Access D when Site Access D is constructed to intersect Linder Road. 3.

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 recommends that Linder Road and Amity Road be constructed as 5-lane minor arterial roadways. The SMTP also recommends the construction of a dual-lane roundabout at the Amity Road and Linder Road intersection and a multi-lane roundabout at the Victory Road and Linder Road intersection. 2. Overland Road/Linder Road Intersection Consistent with the findings and recommendations of the traffic impact study, the applicant should be required to extend the westbound left-turn lane an additional 75-feet within the existing travel lane on Overland Road at Linder Road and extend the northbound right-turn lane on Linder Road at Overland Road to the extent that is allowable without causing conflict with the existing driveway located on the east side of Linder Road south of the Overland Road/Linder Road intersection prior to plan approval and ACHD's signature on the final plat that contains the 39111 building lot. Compensation will not be provided for additional pavement widening. Coordinate the design of the turn lanes with ACHD's Development Review staff. 3. Victory Road/Linder Road Intersection The TIS recommends this intersection be constructed as a single lane roundabout or interim 3x3 traffic signal be installed to accommodate 2030 total traffic conditions when the site generates 244 PM peak hour trips or the equivalent of 386 single family lots and 79 multi-family dwelling units. To verify the assumptions of the TIS and to ensure that improvements are made, when necessary, the applicant should be required to submit an updated intersection analysis for the Linder Road/Victory Road intersection prior to ACHD's approval of the final plat that contains the 38711 single family building lot. If additional right-of-way has been dedicated at this intersection staff will review the updated analysis and determine at that time what improvements may be required. Additional improvements may be required based on the findings of the updated traffic impact study. If right-of-way has not been dedicated at this intersection, then the applicant should be required to submit a plan for alternative mitigation as recommend in the TIS for review and approval, as improvements are required to be constructed consistent with the alternative mitigation policy. Consistent with the findings and recommendations of the traffic impact study the applicant should be required to construct a westbound left-turn lane on Victory Road at Linder Road with a minimum 75-feet of storage and a northbound left-turn lane on Linder Road at Victory Road with a minimum 50-feet of storage prior to plan approval and ACHD's signature on the final plat that contains the 391st building lot.

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's Proposal: The applicant is proposing to construct Farmyard Avenue from the intersection of Wild Stallion Way east to intersect Linder Road as a 33-foot wide local street section with curb, gutter, and a portion of an 8-foot wide planter strip within 47-feet of right-of- way and 5-foot wide detached concrete sidewalk located outside of the right-of-way. The applicant is proposing to construct the other internal local streets as 33-foot wide street sections with rolled curb, gutter and 5-foot wide attached concrete sidewalk within 47-feet of right-of-way. The applicant is proposing to construct a cul-de-sac turnaround at the terminus of Hay Store Drive and at the north and south end of Cultivator Place. The applicant is proposing to construct 8 knuckles throughout the site. d. Staff Comments/Recommendations: The applicant's proposal to construct Farmyard Avenue from the intersection of Wild Stallion Way east to intersect Linder Road as a 33-foot wide local street section does not meet District policy and should not be approved, as proposed. See Section C7d. page 18 and 19 for construction requirements. The applicant's proposal to construct the other internal local streets as 33-foot wide street sections with rolled curb, gutter and 5-foot wide attached concrete sidewalk within 47-feet of right-of-way meets District policy and should be approved, as proposed. The applicant should be required to construct the proposed cul-de-sacs with a minimum turning radius of 50-feet at the terminus of Hay Store Drive and at the north and south end of Cultivator Place. The applicant's proposal to construct 8 knuckles throughout the site meets District policy and should be approved, as proposed. 22 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 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 back of sidewalk. Sidewalk shall be located wholly within right-of- way or wholly within an easement. 10. 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 1 a (7205.4.6). Collector Offset Policy: District policy 7205.4.2 states that the optimum spacing for new signalized collector roadways intersecting minor arterials is one half-mile. District policy 7205.4.6 states that preferred spacing for new unsignalized collectors intersecting minor arterials is 1,320-feet. 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). c. Applicant's Proposal: The applicant is proposing to construct a new collector roadway, Harris Street, to intersect Linder Road located a '/2 mile south of Victory Road. The applicant is proposing to construct a collector roadway, Farmyard Avenue, to intersect Harris Street, located 2,080-feet west of Linder Road. The applicant is proposing to construct two new local streets to intersect the proposed collector street, Harris Street, at the following locations: • Brown Swiss Way, a local street, located 1,420-feet west of Linder Road • International Way, a local street, located 440-feet west of Linder Road The applicant is proposing to construct a new local street, Farmyard Avenue, to intersect Linder Road located 1,060-feet north of the Amity Road. The applicant is proposing to construct one new collector roadway, Wild Stallion Way, to intersect Farmyard Avenue located 1,400-feet west of Linder Road. The applicant is proposing to construct four new local streets to intersect the proposed collector street, Farmyard Avenue, at the following locations: • Twin View Street, located 540-feet south of the proposed collector street, Harris Street • Boar Run Avenue, located 830-feet southeast of Twin View Street • Planters Avenue, located 960-feet west of Linder Road • Tractor Avenue, located 480-feet west of Linder Road 23 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 The applicant is proposing to construct all other local internal streets to align or offset by a minimum of 125-feet. d. Staff Comments/Recommendations: The applicant's proposal to construct a new collector roadway, Harris Street, to intersect Linder Road located a '/z mile south of Victory Road meets District policy and should be approved, as proposed. The Master Street Map (MSM) identifies the new north/south collector street, Farmyard Avenue, to be located at the site's west property line. However, as part of Burnside Ridge Estates Farmyard Avenue was shifted further east due to the location of existing homes and shops/barns west and south of the site, making it infeasible to construct the roadway as shown on the MSM. Staff recommends approval of the location as it will align with Farmyard Avenue as part of Burnside Ridge Estates located directly adjacent to the north of the site. The applicant's proposal to construct two new local streets to intersect the proposed collector roadway, Harris Street, meets District policy and should be approved, as proposed. The applicant's proposal to construct a new local street, Farmyard Avenue, to intersect Linder Road located 1,580-feet south of the proposed collector street, Harris Street has been required to be constructed as a collector street, see Section C7d, page 18 and 19 and does not meet District Collector Offset policy which states the preferred spacing for new unsignalized collectors intersecting minor arterials is 1,320-feet. Staff recommends approval of the location as a collector roadway is required due to the amount of average daily trips on this roadway. The applicant's proposal to construct one new collector street, Wild Stallion Way, to intersect Farmyard Avenue located 1,400-feet west of Linder Road meets District policy and should be approved, as proposed. The applicant's proposal to construct four new local streets to intersect the proposed collector street, Farmyard Avenue, meets District policy and should be approved, as proposed. The applicant's proposal to construct all other local internal streets to align or offset by a minimum of 125-feet meets District policy and should be approved, as proposed. 11. Stub Streets a. Existing Conditions: There are no existing stub streets to or from the site. b. Policy: Stub Street Policy: District policy 7206.2.4.3 states that stub streets will be required to provide circulation or to provide access to adjoining properties. Stub streets will conform with the requirements described in Section 7206.2.4, except a temporary cul-de-sac will not be required if the stub street has a length no greater than 150-feet. A sign shall be installed at the terminus of the stub street stating that, "THIS IS A DESIGNATED COLLECTOR ROADWAY. THIS STREET WILL BE EXTENDED AND WIDENDED IN THE FUTURE." In addition, stub streets must meet the following conditions: • A stub street shall be designed to slope towards the nearest street intersection within the proposed development and drain surface water towards that intersection; unless an alternative storm drain system is approved by the District. • The District may require appropriate covenants guaranteeing that the stub street will remain free of obstructions. Temporary Dead End Streets Policy: District policy 7206.2.4.4 requires that the design and construction for cul-de-sac streets shall apply to temporary dead end streets. The temporary cul-de-sac shall be paved and shall be the dimensional requirements of a standard cul-de-sac. The developer shall grant a temporary turnaround easement to the District for those portions 24 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 of the cul-de-sac which extend beyond the dedicated street right-of-way. In the instance where a temporary easement extends onto a buildable lot, the entire lot shall be encumbered by the easement and identified on the plat as a non-buildable lot until the street is extended. c. Applicant Proposal: The applicant is proposing to construct one stub street, Wild Stallion Way, to the south, located 1,400-feet west of Linder Road. d. Staff Comments/Recommendations: The applicant's proposal to construct one stub street to the south meets District policy and should be approved, as proposed. If the northern half of Harris Street has not been constructed along the site's north property line as part of the Burnside Ridge Estates development, then the applicant should be required to stub Harris Street to the site's northwest property line. The applicant should be required to construct a temporary cul-de-sac turnaround at the terminus of Wild Stallion Way and Harris Street, as they extend greater than 150-feet. The temporary turnaround should be paved and constructed to the same dimensional standards as a standard cul-de-sac turnaround. If the turnaround extends onto a buildable lot, the entire lot shall be encumbered by the easement and identified on the plat as a non-buildable lot until the street is extended. The applicant should install a sign at the terminus of Wild Stallion Way and Harris Street that states, "THIS IS A DESIGNATED COLLECTOR ROADWAY. THIS STREET WILL BE EXTENDED AND WIDENED IN THE FUTURE." 12. Private Road/Driveways a. Existing Conditions: There are no private road/driveways within the site. b. Policy: 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. 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 is proposing to construct two 30-foot wide private road/drive aisles as curb return type driveways that run east/west located between two 25 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 proposed local streets, Cowboy Boot Avenue and Brown Swiss Way near the site's northwest property line. The applicant is proposing to construct two 30-foot wide private road/drive aisles onto the following proposed local streets: • Wind Vane Drive and in alignment with Tractor Avenue • Tractor Avenue in alignment with Wind Vane Drive d.

N I I I I /L required to pave the private roadways their 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 and stop 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. 13. Traffic Calming a. Speed Control and Traffic Calming Policy: District policy 7206.3.8 states that collector streets should be designed to discourage speeds above 35 MPH and in a residential area, collector streets should be designed to discourage speeds above 30 MPH. The design of collector street 26 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 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, 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 a maintenance and/or license agreement. 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, 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 are several long sections of roadways proposed that are greater than 750-feet in length and will need to be redesigned to reduce the length of the roadways or to include the use of passive design elements. The ultimate locations and design will be determined during plan review by Development Review staff. The roadways greater than 750-feet in length are as follows: • Farmyard Avenue • Burning Oak Street • Twin View Street • Shaker Round Street • Fallow Run Drive • Cattle Run Way Stop signs, speed humps/bumps and valley gutters will not be accepted as traffic calming. 14. Bridge for Calkins Lateral Crossing The District will require that the applicant have ACHD approved plans for the crossing of Calkins Lateral prior to the pre-construction meeting and final plat approval. Note: Timing of project plan submittals should take into account review times, lead time for precast members and potential roadway closures. To ensure construction prior to irrigation season, approval of the project plans must be attained by January 151h. The District retains the right to modify road closure approvals on any project based on the needs of the District. Construction of projects approved after January 15th may be postponed until after irrigation season is over in October. It is recommended that bridge submittals be submitted before the end of the current irrigation season to ensure the best time frame for construction is attained. Submittals will need to include the street section extending over the bridge to ensure the requirements of the roadway are met. 15. 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. 16. 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 27 DRAFT Tessera Ranch/ MPP21-0027/ H-2022-0020 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. 17. Other Access Linder Road and Amity Road are classified as minor arterial roadways and Farmyard Avenue, Harris Street and Wild Stallion Way are classified as collector roadways. Other than the access specifically approved with this application, direct lot access is prohibited to these roadways and should be noted on the final plat. D. Site Specific Conditions of Approval 1. Prior to ACHD's signature on the first final plat, submit a revised preliminary plat showing the redesigned roadways to reduce the length of the roadways or to include the use of passive design elements.

Traffic Impact Study Tessera Subdivision—Meridian, Idaho EXECUTIVE SUMMARY Hubble Homes is planning to develop the Tessera Subdivision project located west of Linder Road between Victory Road and Amity Road in Meridian, Idaho, as shown in Figure 1.1. CR Engineering, Inc. has been retained to prepare a traffic impact study(TIS) for the proposed development. The scope of this TIS was determined through coordination with the Ada County Highway District(ACHD)and the Idaho Transportation Department(ITD)with inputs from the Community Planning Association of Southwest Idaho(COMPASS). The TIS evaluates the potential traffic impacts resulting from background traffic growth, in-process developments in the area, and the proposed development, and identifies improvements to mitigate the impacts if needed. Traffic impacts were evaluated under weekday AM and PM peak hours traffic conditions. Table 1 summarizes the improvements needed to mitigate the traffic impacts for the following analysis years traffic conditions: ■ 2021 Existing traffic ■ 2030 Build-out year background traffic ■ 2030 Build-out year total traffic 1.0 Proposed Development 1.1 Tessera Subdivision is a proposed residential development estimated to contain 407 single-family dwelling units and 79 multifamily dwelling units. The expected build-out year is 2030 which may change depending on market conditions. 1.2 Based on the procedures outlined in the Trip Generation Handbook, 3Ya Edition and the Trip Generation Manual, IF" Edition, both published by the Institute of Transportation Engineers (ITE), the proposed development is estimated to generate approximately 4,253 trips per weekday with 314 trips during the AM peak hour and 427 trips during the PM peak hour. ■ Based on the proposed land uses,no internal capture or pass-by trips were assumed in the analysis ■ All trips were assumed to be made by personal or commercial vehicles 1.3 The estimated site traffic distribution patterns are: ■ 30%north of the site traveling on Linder Road ■ 20%north of the site traveling on Meridian Road ■ 10% south of the site traveling on Linder Road ■ 5% south of the site traveling on Meridian Road ■ 5%east of the site traveling on Victory Road ■ 5%east of the site traveling on Amity Road ■ 15%west of the site traveling on Victory Road ■ 10%west of the site traveling on Amity Road March 2022 1 ITT�.'NGIN�RING,INC.
