Lead Agency: City of Meridian Site address: South of Lake Hazel Road and East of Locust Grove Road, Parcel Number S 1405223020 Staff Approval: May 17, 2021 Vicini� Map Applicant: Elias Felix _ I pp , Paradigm Design i 4250 N. Drinkwater Boulevard, Suite 120 �7 Scottsdale, AZ 85251 Representative: Same as above r Staff Contact: Paige Bankhead, E.I. Phone: 387-6293 g., E-mail: pbankheadCa)_achdidaho.org A. Findings of Fact 1. Description of Application: The applicant is requesting approval to construct a 45,110 square foot K-12 charter school on 6.1 acres. The site is zoned C-C (Community Business District). The City of Meridian's Future Land Use Map designates this area as medium density residential and a neighborhood center. 2. Description of Adjacent Surrounding Area: Direction Land Use Zoning North Community Business District/Medium-High Density Residential C-C/R-15 South Medium Density Residential R-8 East Park R-4 West Medium Density Residential R-8 3. Site History: ACHD Commission previously reviewed this site as part of Apex Southeast Subdivision, MPP20-0009 in August 2020. The requirements of this staff report 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 Gem Prep South MER21-0010/H-2021-0020 • Apex Southeast Subdivision, 237 residential lots, 2 commercial lots, 30 common lots and 10 other lots on 63 acres located directly south and west of the site and was approved by the ACHD Commission on August 5, 2020. • Apex Northwest Subdivision, 120 residential lots, 11 commercial lots, and 14 common lots on 41.8 acres located to the northwest of the site and was approved by the ACHD Commission on August 5, 2020. • Lavender Heights Subdivision, 187 residential lots, 1 multi-family lot, 24 common lots and 3 other lots on 55.1 acres located northeast of the site and was approved by ACHD on March 27, 2020. • Discovery Park, a 77-acre park located directly east of the site. The development application for the second phase of the park currently under review. 5. Transit: Transit services are not available to serve this site. 6. Gas Pipeline: The Williams Pipeline falls within the proposed development. Coordination with the owner of the pipeline prior to final design is recommended to ensure that their requirements are met. ACHD requires written approval from the owner of the pipeline prior to plan acceptance if public street improvements are proposed or required within the pipeline easement. 7. 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. 8. New Center Lane Miles: The proposed development includes 0.0 centerline miles of new public road. 9. 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. 10. Capital Improvements Plan (CIP)/ Integrated Five Year Work Plan (IFYWP): • The intersection of Lake Hazel Road and Locust Grove Road is listed in the CIP to be reconstructed as a multi-lane roundabout with 4-lanes on the east and west legs and 2-lanes on the north and south legs between 2036 and 2040. The applicants for Apex Southeast Subdivision, which includes this site, have entered into a Cooperative Development Agreement (CDA) with ACHD to improve the intersection consistent with the CIP. The construction plans for the intersection improvements are currently under review. • Lake Hazel Road is listed in the CIP to be widened to 5-lanes from Locust Grove Road to Eagle Road between 2036 and 2040. The applicants for Apex Southeast Subdivision, which includes this site, have entered into a CDA with ACHD to widen this segment of Lake Hazel 2 Gem Prep South MER21-0010/1-1-2021-0020 Road to 5-lanes consistent with the CIP. The construction plans for the roadway improvements are currently under review. 11. 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 Lake Hazel Road as Level 3 facility. The BMP also identifies a Level 1 facility on the new collector roadway abutting the site. The Apex Southeast Subdivision applicant entered into a CDA with ACHD to widen Lake Hazel Road abutting the site consistent with the CIP and construct a 10-foot multi-use pathway on both sides of the roadway, consistent with the BMP. That applicant was required to construct the new collector roadway with Level 1 facilities consistent with the BMP. B. Traffic Findings for Consideration 1. Trip Generation: This development is estimated to generate 590 vehicle trips per day; 354 trips per hour in the AM peak hour and 208 trips per hour in the PM peak hour based on the traffic impact study. 2. Traffic Impact Study CivTech prepared a school site checklist for the proposed Gem Prep South, as required per Idaho Code 67-6519(3). The school site checklist can be found as Attachment 3. The school site checklist is not the opinion of ACHD staff. ACHD has reviewed the submitted school site checklist 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. 3 Gem Prep South M ER21-0010/H-2021-0020 E.WSEHQLRO,- _.. --- -- -- --- — - --- -- ILI �4 . x- x� tf� _ :r �;I f W I.!ny1. 1.

Staff Comments/Recommendations: Staff generally agrees with the findings and recommendations presented in the school site checklist. The school site checklist indicated that dedicated turn lanes are not warranted at the site accesses on Vertex Way (Bloomerang Avenue), Tower Street, Peak Avenue, or on Lake Hazel Road at Peak Avenue. As part of ACHD's action on Apex Southeast Subdivision, that applicant was required to construct an eastbound dedicated right- turn lane on Lake Hazel Road at Vertex Way and the applicant entered into a CDA with ACHD to widen Lake Hazel Road to 5-lanes. The applicant was also required to construct a continuous center turn lane on Vertex Way (Bloomerang Avenue) and Tower Street east of Peak Avenue. The construction plans for these improvements and construction of Peak Avenue, Vertex Way (Bloomerang Avenue) and Tower Street abutting the site are currently under review. Staff agrees with the locations of the crosswalks proposed on Tower Street and Peak Avenue, as well as the crossing proposed at the driveway onto Tower Street, as shown above. The applicant should be required to sign and stripe those crosswalk locations and provide crossing guards consistent with the recommendations in the school site checklist. 4 Gem Prep South M ER21-0010/H-2021-0020 Staff agrees with the proposed school zone area at the intersection of Tower Street and Peak Avenue. The applicant should be required to install school zone flashers, striping and signage on Tower Street and Peak Avenue for the designated school zone that is proposed, consistent with ACHD standards. The applicant should be required to coordinate a signage program with Development Review staff. The school site checklist shows that signals are not warranted at the intersections of Vertex Way/Lake Hazel Road or Peak Avenue/Lake Hazel Road. Staff agrees with this assessment. The Gem Prep shall be responsible for all costs associated with the design, hardware, and construction of any pedestrian facilities needed to accommodate future pedestrian needs of the school. This includes flashing beacons, crosswalk striping and signage, and HAWK signals or RRFBs. 3. Condition of Area Roadways Traffic Count is based on Vehicles per hour(VPH) Functional PM Peak PM Peak Roadway Frontage Classification Hour Hour Level Traffic Count of Service Principal Better than Lake Hazel Road 605-feet Arterial 255 "D" * Acceptable level of service for a two-lane principal arterial is "E" (690 VPH). 4. Average Daily Traffic Count (VDT) Average daily traffic counts are based on ACHD's most current traffic counts. • The average daily traffic count for Lake Hazel Road east of Locust Grove Road was 6,326 on 08/29/2019. C. Findings for Consideration 1. South Meridian Transportation Plan The South Meridian Transportation Plan (SMTP) is a long-range planning tool used to identify future roadway, intersection, and corridor needs in the South Meridian Area. Providing a framework for future roadway improvements based on the land use designations. The plan was created in collaboration with the City of Meridian and was adopted by the ACHD Commission in September of 2009. The SMTP recommends the following abutting and within the site: • Preserving right-of-way for the future widening of Lake Hazel Road to 5-lanes and the construction of 6-foot wide detached sidewalks on Lake Hazel Road. • Preserving right-of-way for future construction of a 3-lane commercial collector roadways and the construction of 6-foot wide detached sidewalks. 2. Lake Hazel Road a. Existing Conditions: Lake Hazel Road is improved with 2-travel lanes and no curb, gutter or sidewalk abutting the site. There is 50-feet of right-of-way for Lake Hazel Road (25-feet from centerline). The applicant for Apex Southeast Subdivision has entered into a CDA to widen Lake Hazel Road to 5-lanes with curb, gutter and a 10-foot wide multi-use pathway abutting the site consistent with the BMP and CIP and was required to dedicate additional right-of-way to total 50-feet abutting the site consistent with the CIP and MSM. 5 Gem Prep South MER21-0010/H-2021-0020 b. Policy: Arterial Roadway Policy: District Policy 7205.2.1 states that the developer is responsible for improving all street frontages adjacent to the site regardless of whether or not access is taken to all of the adjacent streets. Master Street Map and Typology Policy: District Policy 7205.5 states that the design of improvements for arterials shall be in accordance with District standards, including the Master Street Map and Livable Streets Design Guide. The developer or engineer should contact the District before starting any design. Street Section and Right-of-Way Width Policy: District Policies 7205.2.1 & 7205.5.2 state that the standard 5-lane street section shall be 72-feet (back-of-curb to back-of-curb) within 96- feet of right-of-way. This width typically accommodates two travel lanes in each direction, a continuous center left-turn lane, and bike lanes on a minor arterial and a safety shoulder on a principal arterial. Right-of-Way Dedication: District Policy 7205.2 states that The District will provide compensation for additional right-of-way dedicated beyond the existing right-of-way along arterials listed as impact fee eligible in the adopted Capital Improvements Plan using available impact fee revenue in the Impact Fee Service Area. No compensation will be provided for right-of-way on an arterial that is not listed as impact fee eligible in the Capital Improvements Plan. The District may acquire additional right-of-way beyond the site-related needs to preserve a corridor for future capacity improvements, as provided in Section 7300. Sidewalk Policy: District Policy 7205.5.7 requires a concrete sidewalk at least 5-feet wide to be constructed on both sides of all arterial streets. A parkway strip at least 6-feet wide between the back-of-curb and street edge of the sidewalk is required to provide increased safety and protection of pedestrians. Consult the District's planter width policy if trees are to be placed within the parkway strip. Sidewalks constructed next to the back-of-curb shall be a minimum of 7-feet wide. Detached sidewalks are encouraged and should be parallel to the adjacent roadway. Meandering sidewalks are discouraged. A permanent right-of-way easement shall be provided if public sidewalks are placed outside of the dedicated right-of-way. The easement shall encompass the entire area between the right- of-way line and 2-feet behind the back edge of the sidewalk. Sidewalks shall either be located wholly within the public right-of-way or wholly within an easement. Frontage Improvements Policy: District Policy 7205.2.1 states that the developer shall widen the pavement to a minimum of 17-feet from centerline plus a 3-foot wide gravel shoulder adjacent to the entire site. Curb, gutter and additional pavement widening may be required (See Section 7205.5.5). ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM) guide the right-of-way acquisition, arterial street requirements, and specific roadway features required through development. This segment of Lake Hazel Road is designated in the MSM as a Mobility Arterial with 5-lanes and on-street bike lanes, a 72-foot street section within 100-feet of right-of-way abutting the site. c. Applicant Proposal: The applicant has not proposed any improvements to Lake Hazel Road. d. Staff Comments/Recommendations: Lake Hazel Road is proposed to be fully improved with the Apex Southeast Subdivision development, which includes this site. The applicant for Apex Southeast Subdivision has entered into a CDA with ACHD to widen Lake Hazel Road to 5-lane 6 Gem Prep South M ER21-0010/H-2021-0020 and construct curb, gutter and a 10-foot wide multi-use pathway abutting the site consistent with the CIP, MSM and BMP. Those construction plans are currently under review. The applicant was also required to dedicate additional right-of-way to total 50-feet from the section line on Lake Hazel Road abutting the site, consistent with the MSM and CIP. These construction plans are currently under review. Typically, the applicant would be required to dedicate additional right-of-way for Lake Hazel Road abutting the site consistent with the MSM and CIP and improve Lake Hazel Road abutting the site with additional pavement widening, gravel shoulder and sidewalk consistent with the District's Frontage Improvements Policy for arterial roadways. However, Lake Hazel Road is going to be fully improved with 5-lanes, curb, gutter and sidewalk with additional right-of-way dedication abutting the site with the Apex Southeast Subdivision development, consistent with the MSM and CIP. The school site checklist also does not recommend that any additional improvements be constructed on Lake Hazel Road abutting the site. Therefore, staff does not recommend that this applicant be required to construct any additional improvements or provide additional right-of-way dedication with this development application. 3. Vertex Way (Bloomerang Avenue) and Tower Street a. Existing Conditions: Vertex Way (Bloomerang Avenue) and Tower Street have not yet been constructed abutting the site. As part of ACHD's action on Apex Southeast Subdivision, that applicant was required to construct Vertex Way (Bloomerang Avenue) and Tower Street abutting the site as a 3-lane collector roadway, a 47-foot wide street section with vertical curb, gutter, 8-foot wide planter strip and 5-foot wide detached concrete sidewalks within 77-feet of right-of-way. These construction plans are currently under review. b. Policy: Collector Street Policy: District policy 7206.2.1 states that the developer is responsible for improving all collector frontages adjacent to the site or internal to the development as required below, regardless of whether access is taken to all of the adjacent streets. Master Street Map and Typologies Policy: District policy 7206.5 states that if the collector street is designated with a typology on the Master Street Map, that typology shall be considered for the required street improvements. If there is no typology listed in the Master Street Map, then standard street sections shall serve as the default. Street Section and Right-of-Way Policy: District policy 7206.5.2 states that the standard right-of-way width for collector streets shall typically be 50 to 70-feet, depending on the location and width of the sidewalk and the location and use of the roadway. The right-of-way width may be reduced, with District approval, if the sidewalk is located within an easement; in which case the District will require a minimum right-of-way width that extends 2-feet behind the back-of- curb on each side. The standard street section shall be 46-feet (back-of-curb to back-of-curb). This width typically accommodates a single travel lane in each direction, a continuous center left-turn lane, and bike lanes. Residential Collector Policy: District policy 7206.5.2 states that the standard street section for a collector in a residential area shall be 36-feet (back-of-curb to back-of-curb). The District will consider a 33-foot or 29-foot street section with written fire department approval and taking into consideration the needs of the adjacent land use, the projected volumes, the need for bicycle lanes, and on-street parking. Sidewalk Policy: District policy 7206.5.6 requires a concrete sidewalk at least 5-feet wide to be constructed on both sides of all collector streets. A parkway strip at least 6-feet wide between the back-of-curb and street edge of the sidewalk is required to provide increased safety and protection of pedestrians. Consult the District's planter width policy if trees are to be placed 7 Gem Prep South MER21-0010/H-2021-0020 within the parkway strip. Sidewalks constructed next to the back-of-curb shall be a minimum of 7-feet wide. Detached sidewalks are encouraged and should be parallel to the adjacent roadway. Meandering sidewalks are discouraged. A permanent right-of-way easement shall be provided if public sidewalks are placed outside of the dedicated right-of-way. The easement shall encompass the entire area between the right- of-way line and 2-feet behind the back edge of the sidewalk. Sidewalks shall either be located wholly within the public right-of-way or wholly within an easement. ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM) guide the right-of-way acquisition, collector street requirements, and specific roadway features required through development. A new collector roadway was identified on the MSM with the street typology of Residential Collector. The new collector roadway should intersect Lake Hazel Road at the quarter mile east of Locust Grove Road and intersect Locust Grove Road approximately at the quarter mile south of Lake Hazel Road. The Commercial Collector typology as depicted in the Livable Street Design Guide recommends a 3-lane roadway with bike lanes, a 46-foot street section within 50 to 70-feet of right-of-way. c. Applicant's Proposal: The applicant has proposed to install school zone flashers with signage on Vertex Way/Tower Street (Bloomerang Avenue) abutting the site. d. Staff Comments/Recommendations: The applicant's proposal to install school zone flashers meets District Policy and should be approved, as proposed. The applicant should be required to install the school zone flashers, signage and striping on Vertex Way/Tower Street (Bloomerang Avenue) abutting the site prior to the opening of the school. As part of ACHD's action on Apex Southeast Subdivision, that applicant was required to construct Vertex Way/Tower Street (Bloomerang Avenue) abutting the site as a 3-lane collector roadway, a 47-foot wide street section with vertical curb, gutter, 8-foot wide planter strip and 5- foot wide detached concrete sidewalks within 77-feet of right-of-way consistent with the MSM. The school site checklist does not recommend any additional improvements for this roadway segment. Therefore, staff recommends no further improvements or right-of-way dedication be required for Vertex Way/Tower Street abutting the site with this development application. 4. Peak Avenue a. Existing Conditions: Peak Avenue has not yet been constructed abutting the site. As part of ACHD's action on Apex Southeast Subdivision, that applicant was required to construct Peak Avenue as a local roadway, a 54-foot wide street section with a continuous 12-foot wide center landscape island, two 21-foot wide travel lanes with vertical curb, gutter, an 8-foot wide planter strip and 5-foot wide detached concrete sidewalks within 81-feet of right-of-way abutting the site. These construction plans are currently under review. b. Policy: Local Roadway Policy: District Policy 7207.2.1 states that the developer is responsible for improving all local street frontages adjacent to the site regardless of whether or not access is taken to all of the adjacent streets. Street Section and Right-of-Way Policy: District Policy 7207.5 states that right-of-way widths for all local streets shall generally not be less than 47-feet wide and that the standard street section shall be 33-feet (back-of-curb to back-of-curb). Standard Urban Local Street-33-foot Street Section and Right-of-way Policy: District Policy 7207.5.2 states that the standard street section shall be 33-feet (back-of-curb to back-of- curb)for developments with any buildable lot that is less than 1 acre in size.

Orchard St. Ste. 200 44<EN Boise, ID 83706 RE: SCHOOL SITE CHECKLIST RESPONSES FOR GEM INNOVATION SCHOOL—MERIDIAN,IDAHO Dear Ms. Bankhead: CivTech is pleased to provide responses to the School Site Checklist for the GEM Innovation Charter School development project located on the southeast corner of Locust Grove Road & Lake Hazel Road, in unincorporated Ada County, south of the City of Meridian, Idaho. The project is part of the larger Apex Southeast Subdivision and is in process with the City of Meridian for annexation and rezoning. The assessment of the development will utilize the School Site Checklist in Idaho Code 67-6519(3) as follows: 1. Land Use Master Plan: The proposed school site is located within a larger development called"Pinnacle Mixed-Used Development"that is on both the northwest corner and southeast corner of Locust Grove Road & Lake Hazel Road. Kittelson and Associates (K&A) prepared a Transportation Impact Study (study) for Brighton Development in March 2020 for the larger mixed-use development. The location of the proposed charter school is shown as"commercial or multi-family" in the study. The proposed project would develop approximately 6.12 acres of farmland to a K-12 charter school land use, instead of the use shown in the study. 2. School Bus Plan: GEM Innovation School will utilize 2 buses in the opening year and add more as the student body population increases over 4 years. Once the school is full of students, it is anticipated that a maximum of 3 buses will be utilized to provide bus service for an estimate of 118 students. Busses will access the school from Tower Street and exit the school on Peak Avenue. Tower Street will be accessed from Lake Hazel Road via Peak Avenue for arriving busses. Departing buses will utilize either Lake Hazel Road or Locust Grove Road via Tower Street. 3. Access Safety: There are three proposed access points to the project, with one (1) new driveway on Peak Avenue, one (1) new driveway on Vertex Way, and one (1) new driveway on Tower Street, all three new roads to be constructed as part of the larger development. Students will be able to enter and exit the bus on the south end of the school building to prevent any vehicles conflicts. Bus access will be the access south of the school building. The parent pick-up/drop-off is directly north of the school building. Parents will be using the east access of the site off of Vertex Way to enter and exit the site. Students will be able to enter and exit on the passenger side of the parent vehicle to prevent conflicts with crossing in front CivTech Inc. • 10605 North Hayden Road •Suite 140•Scottsdale,AZ 85260 Phone: 480.659.4250• Fax: 480.659.0566 Advanced Memorandum GEM Innovation School-Meridian, Idaho March 16, 2021 Page 2 of vehicles. School staff are anticipated to arrive before the students'arrival and upon leaving school staff will be anticipated to leave later than the students to avoid any conflicts with buses or parents'drop off. 4. Pedestrian Plan: There are no existing sidewalks or bike lanes in the vicinity of the development. The City of Meridian Comprehensive Plan states, the City regularly requires developers to install sidewalk, micro-pathways and multi-use pathways that connects to school sites."to ensure safe routes to school. Sidewalks along all site adjacent roads will be required upon build out. Sidewalks as part of the adjacent roadway development will be constructed as part of the larger mixed-use development. Students are to enter and exit the school site on the south side of the site, directly east of the South Parking Lot Entrance on Tower Street. 5. Crossing Guard Plan: A crossing guard will be required for students that are walking and biking to school. Pedestrian crossings with crossing guards are recommended across the north leg of the intersection of Peak Avenue & Tower Road, and across the north, east, and south legs of the intersection of South Parking Lot Entrance & Tower Road. The proposed locations for crosswalks/crossing guards and the school zone are shown in Figure 1. — CiVTeCh Advanced Memorandum GEM Innovation School-Meridian, Idaho March 16, 2021 Page 3 E.LAn HAZEL RD. ............... t1p A Legend Crosswalk School Zone E. T. GEM SCHOOL-SITE PLAN Figure 1 — Site Plan and Crossing Guard 6. Barriers between Highways and Schools: A 25-foot-wide landscape buffer, driveway lanes, parking areas, and internal and external sidewalks are proposed between the school and Lake Hazel Road. ,Cc CivTech Advanced Memorandum GEM Innovation School-Meridian, Idaho March 16, 2021 Page 4 7. Location of School Zone: GEM Innovation School is within the West Ada School District Boundary; therefore, the school zone should follow West Ada School District Policy stating that all schools should have a school zone for schools that fronts on the main roadway. School zones will be required along portions of Tower Street, Vertex Way, and Peak Avenue where students enter and exit the school site. The extent of the school zone is recommended to include the intersection of Peak Avenue & Tower Street, continue east as Tower Street transitions into Vertex Way then terminate just southwest of the intersection of Unnamed Local Road &Vertex Way. 8. Need for Flashing Beacon: The school zone is not planned for a major roadway. Flashing beacons are not recommended. 9. Need for a Traffic Control Signal: Two intersections adjacent to the proposed school site need to be considered for traffic signal control needs; Peak Avenue & Lake Hazel Road, and Vertex Way & Lake Hazel Road. Traffic due to the proposed school, traffic from the rest of the proposed development, and existing traffic grown to the study year 2025 are added together (as shown in Figure 2b) for this analysis. Based on the expected level of service and expected peak hour delay at these intersections, signalization is not recommended. The MUTCD contains warrants to provide guidance on determining if signalization of an intersection should be recommended. MUTCD Warrant 5, School Crossing is relevant for this analysis. Some students can be expected to need to cross Lake Hazel Road. The proposed roundabout at the intersection of Locust Grove Road & Lake Hazel Road is planned to include pedestrian crosswalks and will provide a safe location for students to cross Lake Hazel Road. Signalization is not recommended at the study intersections based on Warrant 5. 10. Anticipated Future Improvements:According to the Community Planning Association of Southwest Idaho also known as COMPASS, the Ada County Long Range Highway & Street Functional Street Classification System for 2040, Lake Hazel Road is proposed to be a 5-lane Residential Mobility Arterial, and Locus Grove Road is proposed to be a minor arterial. Peak Avenue is proposed to be local roads. Vertex Way and Tower Street are proposed to be collector roads. The intersection of Locust Grove Road & Lake Hazel Road is proposed to be improved to a 2-lane roundabout. 11. Speed on Adjacent Highways: Lake Hazel Road has an existing posted speed limit of 50 mph. Locust Grove Road has an existing posted speed limit of 50 mph. 12. Traffic Volumes on Adjacent Highways: CivTech utilized traffic counts data from the larger development study for a segment of Lake Hazel Road west of Eagle Road. The latest data traffic counts were recorded was on December 10, 2019. The AM peak hour refers to the highest volume hour between 7am and 9am on a weekday; this is the same for school generated traffic and surrounding traffic. The PM peak hour refers to the highest volume hour between 3pm and 5pm on a weekday; this is the peak hour for school generated traffic but not for surrounding traffic. The existing volumes from between 3pm and 5pm were used for this analysis. The larger development study utilized a growth rate of 7 percent per year for their analysis. This same growth rate was used here. The segment traffic counts were grown to study year CiVTeCh Advanced Memorandum GEM Innovatlon School-Meridian, Idaho March 16, 2021 Page 5 2025 values by multiplying the 2019 values by a 1.501 growth factor (1.07A6). The 24-hour traffic calculated to be 8,612 bi-directional trips with 892 trips (482 eastbound/410 westbound) during the AM peak hour and 857 trips (341 eastbound/516 westbound) during the PM peak hour. The proposed surrounding development is expected to produce traffic as included in the K&A study. The proposed school is expected to produce trips as shown in Table 2a and Table 1b.

For each the opening and buildout year, the school trips are distributed to the surrounding road network using distribution percentages based on residential population within a 3-mile radius, then added to surrounding development and background volumes to predict the proposed volumes. The volumes at the study intersections are shown in Figure a and Figure 2b.

Effect Upon the Highway's Level of Service: Increases in traffic on Lake Hazel Road are likely to result in increased delay during the AM peak hour, and the school's PM peak hour between 3pm and 5pm, but not the PM peak hour of the surrounding road network between 4pm and 6 pm. As discussed above, the school's AM peak hour is expected to coincide with the peak hour of the surrounding road network while the PM peak hour is not expected to coincide with the peak hour of the surrounding road network. The concept of level of service (LOS) uses qualitative measures that characterize operational conditions within the traffic stream. The individual levels of service are described by factors that include speed, travel time, freedom to maneuver, traffic interruptions, and comfort and convenience. Six levels of service are defined for each type of facility for which analysis procedures are available. They are given letter designations A through F, with LOS A representing the best operating conditions and LOS F the worst. Each level of service ,CC CiVTech Advanced Memorandum GEM Innovation School-Meridian, Idaho March 16, 2021 Page 8 represents a range of operating conditions. Levels of service for intersections are defined within ranges of average control delay per vehicle, the number of seconds a vehicle can expect to wait due to the presence of a traffic control device. Table 2 lists the level of service criteria for signalized and unsignalized intersections, respectively. Table 3 - Level of Service Criteria for Controlled Intersections Signalized Unsignalized Level-of-Service Control D-lay (sec/veh) Control Delay A 15 10 <_ 10 B = > 10-20 > 10-15 ......................................................................................................................................: C - > 20-35 > 15-25 ......................................................................................................................................

The AM peak hour levels of service at the study intersections without the school development in place, as provided in the larger development study, are shown for comparison. The larger development study's PM peak hour does not coincide with this study's PM peak hour; those values from the larger development study are not shown. The larger development study does not include level of service analysis for the 2021 year.

Need for Acceleration and Deceleration Lanes: The projected cross section of Lake Hazel Road is to be as a 5-lane road with two lanes in each direction of travel and a two-way left- CiVTech Advanced Memorandum GEM Innovation School-Meridian, Idaho March 16, 2021 Page 9 turn lane. Based on this configuration, no exclusive left-turn lanes along Lake Hazel Road are appropriate. Based on the projected AM and PM peak hour volumes above, and the right-turn deceleration lane guidance given in the ACHD Po/icy Manua/ Section 7106, a dedicated eastbound right-turn lane is expected to not be warranted at the intersection of Peak Avenue & Lake Hazel Road. An eastbound right-turn lane may be warranted at the intersection of Vertex Way & Lake Hazel Road. The projected cross section of Vertex Way, Tower Road, and Peak Avenue are to be as a 2- lane road with one lane in each direction of travel. Based on this configuration, the projected AM and PM peak hour volumes above, and the left-turn deceleration lane guidance given in the ACHD Po/icy Manual Section 7106, no exclusive left-turn lanes along any of these roads are recommended. Based on this configuration, the projected AM and PM peak hour volumes above, and the right-turn deceleration lane guidance given in the ACHD Po/icy Manual Section 7106, no dedicated right-turn lanes along any of these roads are recommended. Any improvements are to be completed as part of the larger proposed development that will construct Peak Avenue, Tower Road, and Vertex Way. 15. Internal Traffic Circulation: The proposed plan is for passenger cars to enter from Vertex Way northeast of the east parking lot, circle around counterclockwise north of the north parking lot, turn back eastbound along the north side of the building where the parent pick-up/drop- off is located, then circle back to exit on Vertex Way. The east and north parking lots can be accessed from this loop. The conceptual site plan provides 1,200 feet of on-site queuing. Bus traffic will access the school from Tower Street, turn left traveling along the east and north side of the south parking lot, and exit the school on Peak Avenue. The student pick- up/drop-off for busses will occur on the east side of the south parking lot. The site includes four parking areas. An east parking lot with 28 spaces is adjacent to the Vertex Way access. A north parking lot with 40 spaces is north of the school building, across the parent pick-up/drip-off. A south parking lot with 36 spaces is accessible from Peak Avenue or Tower Street and is separated from the school building by the bus pick-up/drop-off. The fourth parking lot with 12 spaces is directly east of the school building. 16. Anticipated Development on Surrounding Undeveloped Parcels: According to the City of Meridian Future Land Use Interactive Map, the areas surrounding the development are zoned to be medium and medium-high density to medium-high density residential land use. The land within the same development as the project site is planned as shown in the study to contain single-family homes(325 units), midrise multi-family homes (220 units), and shopping (61,060 square feet). 17. Zoning in the Vicinity: The project site is undergoing rezoning to Community Business District (C-C) and is currently being used for farm land. East of the site is land designated as Civic land designated as Medium Density Residential. South of the site is land designated Medium Density Residential. West of the site is land designated Medium Density Residential and land designated Medium-High Density Residential. North of the site is land designated Medium Density Residential and land designated Medium-High Density Residential. Zoning on CiVTeCh Advanced Memorandum GEM Innovation School-Meridian, Idaho March 16, 2021 Page 10 surrounding land is identified as "Varies by project and location" by the Meridian City Future Land Use Map and associated Future Land Use Map Designation Cut Sheets. 18.Access Control on Adjacent Highways: Lake Hazel Road is currently classified as a Residential Mobility Arterial. The school site is expected to utilize two new roads, Peak Avenue and Vertex Way, to access Lake Hazel Road. The intersection of Peak Avenue & Lake Hazel Road is proposed to be restricted to right-turns only. Stop control on the northbound approach is expected. The intersection of Vertex Way & Lake Hazel Road is proposed to be full access. Stop control for the northbound and southbound approaches is expected. Sight distance requirements were calculated at the intersections of Peak Avenue &Lake Hazel Road, Vertex Way & Lake Hazel Road, Peak Avenue & South Lot, South Lot & Tower Road, and Vertex Way & North Lot. Distance requirements based on the American Association of State and Highway Transportation Officials (AASHTO) methodology are detailed in Table . The ACHD Policy Manual Section 7211.2 includes more strict requirements for left of driveway site distance. A minimum of value based on these standards is also shown in Table 4. Table 4— Sight Distance ACHD • Sight Distance Along Roadway Posted Speed Sight Left of Right of On Major Roadway Limit(mph) Distance Driveway Driveway . . .
