Traffic Impact Study - Summary and Findings 1. Traffic Impact Study Kittelson & Associates, Inc prepared a traffic impact study (TIS) for the proposed Meridian Commerce Park; this site was included as part of that study. An executive summary of the findings as presented by Kittelson &Associates, Inc can be found as Attachment A. 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 TIS. Staff comments and recommendations on the submitted traffic impact study can be found below. a. Policy: Mitigation Proposals: Mitigation recommendations shall be provided within the report. At a minimum, for each roadway segment and intersection that does not meet the minimum acceptable level of service planning threshold or v/c ratio, the report must discuss feasible measures to avoid or reduce the impact to the system. To be considered adequate, measures should be specific and feasible. Mitigation may also include: • Revision to the Phasing Plan to coincide with the District's planning Capital Projects. • Reducing the scope and/or scale of the project. Alternative Mitigation Measures: 7106.7.3 states that if traditional mitigation measures such as roadway widening and intersection improvements are infeasible as determined by ACHD, the TIS may recommend alternative mitigation measures. Alternative mitigation measures shall demonstrate that impacts from the project will be offset. • 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, defined as the hour prior to after the determined peak hour within the two-hour peak period, (sometime analyzed as hour before or after peak period) 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 measures beyond improvements from District policy, such as: off-site sidewalks, off-site 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 7205.3.1 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 7 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 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. TIS Findings: Staff has reviewed the submitted traffic impact study (TIS). The traffic impact study was prepared for the entire site and the following comments and recommendations are specific to the proposed L Building portion of the site. The TIS indicates that the roadway segment and the intersections in the study area are anticipated to operate at an acceptable level of service planning threshold under existing and 2030 background conditions except for the following intersection and roadway segment: • Franklin Road/McDermott intersection- the northbound and southbound approaches are anticipated to exceed ACHD's acceptable level of service planning thresholds. o It is recommended to widen Franklin Road to 5-lanes with a center two-way-left turn for approximately '/4 mile east and west of McDermott Road to provide a two- stage left-turn lane from McDermott Road to Franklin Road. o An Interim 3X3 signal is warranted; however, not found to mitigate the operation of the intersection due to the high westbound volumes in the PM peak hour. • Franklin Road from Black Cat Road to McDermott Road—the eastbound and westbound movements are anticipated to exceed ACHD's acceptable level of service planning thresholds in the AM and PM peak hours under 2030 background and 2030 total traffic conditions. o It is recommended to widen Franklin Road to 5-lanes. Both the Franklin Road/McDermott Road intersection and Franklin Road between Black Cat Road to McDermott Road are listed as funded improvements in ACHD's IFYWP and CIP; therefore, consistent with Alternative Mitigation Measures policy, no mitigation is required c. Staff Comments/Recommendations: Staff comments are provided by District Traffic Services and Development Review staff. The intersection of Black Cat Road and Grand Mogul Drive is recommended to be signalized with dual eastbound left-turn lanes when the site generates 384 PM peak hour trips. Previous staff reports by ACHD indicate St. Lukes' CSC development (MPP22-0001) and the "K" buildings (MER24-0019) will generate 110 and 37 PM peak hour trips, respectively. Staff calculations expect building "L", part of this development application, to generate 33 PM peak hour trips,for a total of 180. The mitigation threshold of 384 trips is not met with this development application; however, this will be reviewed and may be required with future development applications within Meridian Commerce Park. The TIS recommends turn lanes on Black Cat Road at its intersection with Grand Mogul Drive and were required as part of ACHD's approval of St. Luke's CSC Building and are currently under construction. 8 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 E. Findings for Consideration This application is for annexation and rezone only. Listed below are some of the findings for consideration that the District may identify when it reviews future development application(s). The District may add additional findings for consideration when it reviews a specific redevelopment application. ACHD does not require frontage improvements as part of this type of development application. 1. Ten Mile Specific Area Plan (TMISAP) The transportation element of the TMISAP is to guide transportation decisions in the Ten Mile Interchange Area. It was developed concurrently with the Land Use and Design Elements and has been designed to preserve the integrity of the arterial road system and the Ten Mile interchange; provide for the use of public transit; enhance pedestrian and bicycle mobility and accessibility; and create transportation infrastructure and promote land use patterns that encourage the sustainable use of resources and reduces demands on natural resources. The TMISAP recommends the construction of an east/west collector roadway, Grand Mogul Drive, located at the site's north property line. Grand Mogul Drive is currently under construction as part of ACHD's approval of St. Luke's Consolidated Service Center located to north of the site. 3 t, •.i W FRANKLIN RD 4 - 20 Future Grand Mogul Drive 4 Site . li7pd 9 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 2. Black Cat Road a. Existing Conditions: Black Cat Road is improved with 2-travel lanes, 24-feet of pavement and no curb, gutter or sidewalk abutting the site. There is 1 00-to-1 05-feet of right-of-way for Black Cat Road (50-to-53-feet from centerline). b. Applicant Proposal: The applicant is proposing to construct a 5-foot detached concrete sidewalk abutting the property and Black Cat Road. c. Staff Comments/Recommendations: Consistent with ACHD policy, as part of a future development application, the applicant should be required to widen the pavement on Black Cat Road to 17-feet from centerline with a 3-foot wide gravel shoulder. Additionally, the applicant should be required to construct a 10-foot-wide multi-use pathway on Black Cat Road located a minimum of 37.5-feet from the center line of Black Cat Road. No additional right-of-way dedication would be required. 3. Grand Mogul Drive a. Existing Conditions: Grand Mogul Drive is currently under construction as part of ACHD's approval of St. Luke's CSC as a fully improved 5-lane street section at its intersection with Black Cat with vertical curb, gutter, an 8-foot-wide planter strip and 10-foot wide multi-use pathway. b. Applicant Proposal: The applicant is not proposing any street improvements to Grand Mogul Drive abutting the site. c. Staff Comments/Recommendations: The applicant's proposal meets district policy and should be approved, as proposed, as part of a future development application. 4. Driveways 4.1 Black Cat Road a. Existing Conditions: There are no existing driveways from the site onto Black Cat Road. b. Applicant's Proposal: The applicant is not proposing any driveway access from the site onto Black Cat Road c. Staff Comments/Recommendations: The applicant's proposal meets district policy and should be approved as part of a future development application. 4.2 Grand Mogul Drive a. Existing Conditions: There are no existing driveways from the site onto Grand Mogul Drive. b. Applicant's Proposal: The applicant is proposing one driveway from the site onto Grand Mogul Drive located approximately 420-feet from Black Cat Road. c. Staff Comments/Recommendations: As part of a future development application, the applicant should be required to construct a 30-to-36-feet-wide driveway, paved its full width, onto Grand Mogul Drive in alignment with the previously approved driveway from the St. Luke's development to the north. 5. Other Access Black Cat Road is classified as a minor arterial roadway, Grand Mogul Drive is classified as a collector roadway. 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. 10 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 F. Policy 1. Federal Accessibility Design Guidelines and Standards District policy 7203.1.1 states that developers shall follow the current version of the U.S. Access Board's Accessibility Guidelines for Pedestrian Facilities in the Public Right-of-Way(PROWAG), 36 CFR Part 1190, September 7, 2023; (Also see, https//www.access-board.gov/prowag and https//www.access-board.gov/files/prowag/planning-and-design-for-alternatives.pdf for additional information). 2. Minor Improvements Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing Highways adjacent to a proposed development may be required. These needed transportation facilities are to correct deficiencies or replace deteriorated facilities. Included are sidewalk and/or bike lane construction or replacement (with physical buffers if missing and needed); construction of transitional sidewalk segments; crosswalk construction or replacement; curb and gutter construction or replacement; repair, replacement or expansion of curb extensions; replacement of unused driveways with curb, gutter, sidewalk, repair or addition of traffic calming or speed mitigation features; installation or reconstruction of pedestrian ramps; pavement repairs; signs, motor vehicle, pedestrian and bicycle traffic control devices; and other similar items. The current version of PROWAG will determine the applicable accessibility requirements for alterations and elements added to existing streets. ACHD staff is responsible for identifying the minor improvements that would be proportionate to the size and complexity of the development. 3. Livable Street Performance Measures District policy 7203.8 states that ACHD has adopted performance measures (level of stress) for evaluating the experience of bicyclists and pedestrians. ACHD seeks to create a transportation network that serves all ages and abilities. Bike and pedestrian facilities built through development should achieve a bike and pedestrian level of traffic stress 1 or 2, with no new bike lane below a minimum of 5-feet. 4. Black Cat Road 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. Improvements shall include transitional segments in accordance with the current version of PROWAG. 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, Livable Streets Design Guide, and the most current ACHD Livable Streets Performance Measures Plan as adopted by the ACHD Commission. 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 The standard 5-lane street section shall be 59-feet (back-of-curb to back-of-curb). This width typically accommodates two travel lanes in each direction, a continuous center left-turn lane or landscaped median with intermittent turn lanes, and curbs and gutters. A 5-lane road shall also include a minimum 10-foot wide multi-use path on both sides with an 8-foot wide buffer from back-of-curb. Other bike facility treatments as defined in the ACHD Bike Master Plan may be approved at the discretion of the ACHD Development Review Supervisor. If an interim on-street bike lane is required in order to connect to existing facilities, the street section shall be 75-feet to allow for a 5-foot wide 11 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 bike lane and 3-foot wide painted buffer. The standard right-of-way width for a 5-lane arterial is 100- feet. If a landscaped median is included in any of these cross sections, the landscaping shall be maintained by license agreement with the adjacent HOA, property owner, or by interagency agreement with the corresponding land use jurisdiction. At the discretion of Traffic Engineering staff, adjustments may be made to the street section, including removal of the continuous center turn lanes or modification to lane widths, where no driveways or intersections are present or to ensure adequate space for pathway and buffers. 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. Pedestrian Facilities: District Policy 7205.5.7 requires a concrete sidewalk at least 5-feet wide are required on both sides of all arterial streets. A parkway strip at least 8-feet wide between the back- of-curb and street edge of the sidewalk is required to provide increased safety and protection of pedestrians. Alternatively, on roadways identified for improvement in the Capital Improvement Plan, a minimum 10-foot wide multi-use path may be required. The path shall be placed in accordance with planned buildout in the Master Street Map with a minimum 8-foot wide planter strip as measured to the closest edge of the path. Street trees are encouraged between the pedestrian facility and the roadway when irrigation and maintenance will occur by the adjacent property owner or HOA through an approved license agreement. Consult the District's planter width policy if trees are to be placed within the parkway strip. In some instances, to match existing conditions, a minimum 7-foot wide sidewalk may be constructed next to the back-of-curb. ACHD Development Review staff will be responsible for determining the required facility. Vertical hardscape alternatives to street trees may be considered in the buffer space when street trees are not practicable. Detached sidewalks and multi-use paths are encouraged and should be parallel to the adjacent roadway. Pedestrian facilities will only be allowed to deviate from a straight line parallel to the roadway when authorized by Development Review staff to accommodate site specific conditions (i.e., street trees, utilities, etc.). Appropriate easements shall be provided if public pedestrian facilities are placed out of the right-of- way. The easement shall encompass the entire area between the right-of-way line and 2-feet behind the back edge of the pedestrian facility. Pedestrian facilities shall either be located wholly within the public right-of-way or wholly within an easement. Curb ramps or blended transitions shall be provided to connect the pedestrian access route at each pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable warning surface in accordance with the current version of PROWAG. Frontage Improvements Policy: District Policy 7205.2.1 states that the developer shall widen the pavement to a minimum of 17-feet from centerline plus a 3-foot wide gravel shoulder adjacent to the entire site. Curb, gutter and additional pavement widening may be required (See Section 7205.5.5). ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM) guide the right-of-way acquisition, arterial street requirements, and specific roadway features required through development. This segment of Black Cat Road is designated in the MSM as a 12 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 Residential Arterial with 5-lanes and on-street bike lanes, a 72-foot street section within 100-feet of right-of-way. 5. Grand Mogul Drive 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. Improvements shall include transitional segments in accordance with ADA and the current version of PROWAG. 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. ACHD reserves the right to require bicycle and pedestrian facilities above those identified in the Livable Streets Design Guide and Master Street Map to ensure the safest facility possible based on current best practice. 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 or multi-use path and the location and use of the roadway. The right-of-way width may be reduced, with District approval, if the sidewalk or multi-use path is located within an easement; in which case the District will require a minimum right-of-way width that extends 2-feet behind the back-of-curb on each side. The standard street section shall be 47-feet (back-of-curb to back-of-curb). This width typically accommodates a single travel lane in each direction, a continuous center left-turn lane, and bike lanes. If a multi-use path is determined to be the required treatment, the street section shall be reduced to 37-feet. If it is determined a continuous center left-turn lane is not appropriate and a path is installed, the street section may be reduced to 26-feet. 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. At the discretion of Traffic Engineering staff, adjustments may be made to the street section, including removal of the continuous center turn lanes or modification to lane widths, where no driveways or intersections are present or to ensure adequate space for pathways and buffers. Pedestrian Facilities: District policy 7206.5.6 requires a concrete sidewalk at least 5-feet wide to be constructed on both sides of all collector streets. A parkway strip at least 8-feet wide between the back-of-curb and street edge of the sidewalk is required to provide increased safety and protection of pedestrians. Consult the District's planter width policy if trees are to be placed within the parkway strip. Sidewalk constructed next to the back-of-curb shall be a minimum of 7-feet wide. Alternatively, on roadways identified as low-stress bikeways in ACHD's Bike Master Plan, a minimum 10-foot wide multi-use path may be required in lieu of sidewalks. ACHD Development Review staff will be responsible for determining the required facility. The path shall be built 8-feet behind the back-of-curb as measured to the closest edge of the path. Street trees are encouraged between the pedestrian facility and the roadway when irrigation and maintenance will occur by the adjacent property owner or HOA through an approved license agreement. Vertical hardscape alternatives to street trees may be considered in the buffer space when street trees are not practicable. Pedestrian facilities should be parallel to the adjacent roadway. Pedestrian facilities will only be allowed to deviate from a straight line when authorized by Development Review staff to meet site specific conditions (i.e., street trees, utilities, etc.). 13 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 Appropriate easements shall be provided if public sidewalks or multi-use paths are placed out of the right-of-way. The easement shall encompass the entire area between the right-of-way line and 2-feet behind the back edge of the sidewalk or multi-use path. Sidewalks shall either be located wholly within the public right-of-way or wholly within an easement. Curb ramps or blended transitions shall be provided to connect the pedestrian access route at each pedestrian street crossing in accordance with the current version of PROWAG. Provide detectable warning surface in accordance with the current version of PROWAG. ACHD Master Street Map: ACHD Policy Section 3111.1 requires the Master Street Map (MSM) guide the right-of-way acquisition, collector street requirements, and specific roadway features required through development. A new collector roadway was identified on the MSM with the street typology of Residential Collector. The new collector roadway should align with Waltman Street west of Linder Road and continue through the property stubbing to the west. The Residential Collector typology as depicted in the Livable Street Design Guide recommends a 2-lane roadway with bike lanes, and on street parking, a 47-foot street section within 69-feet of right-of-way. 6. Driveways 6.1 Black Cat Road Access Points Policy: District Policy 7205.4.1 states that all access points associated with development applications shall be determined in accordance with the policies in this section and Section 7202. Access points shall be reviewed only for a development application that is being considered by the lead land use agency. Approved access points may be relocated and/or restricted in the future if the land use intensifies, changes, or the property redevelops. Access Policy: District policy 7205.4.6 states that direct access to minor arterials is typically prohibited. If a property has frontage on more than one street, access shall be taken from the street having the lesser functional classification. If it is necessary to take access to the higher classified street due to a lack of frontage, the minimum allowable spacing shall be based on Table 1 a under District policy 7205.4.6, unless a waiver for the access point has been approved by the District Commission. Driveway Location Policy: District policy 7205.4.5 requires driveways located on minor arterial roadways from a signalized intersection with a single left turn lane shall be located a minimum of 330-feet from the nearest intersection for a right-in/right-out only driveway and a minimum of 660- feet from the intersection for a full-movement driveway. District policy 7205.4.5 requires driveways located on minor arterial roadways from a signalized intersection with a dual left turn lane shall be located a minimum of 330-feet from the nearest intersection for a right-in/right-out only driveway and a minimum of 710-feet from the intersection for a full-movement driveway. Successive Driveways: District policy 7205.4.6 Table la, requires driveways located on minor arterial roadways with a speed limit of 45 MPH to align or offset a minimum of 380-feet from any existing or proposed driveway. Driveway Width Policy: District policy 7205.4.8 restricts high-volume driveways (100 VTD or more)to a maximum width of 36-feet and low-volume driveways (less than 100 VTD)to a maximum width of 30-feet. Curb return type driveways with 30-foot radii will be required for high-volume driveways with 100 VTD or more. Curb return type driveways with 15-foot radii will be required for low-volume driveways with less than 100 VTD. Driveway Paving Policy: Graveled driveways abutting public streets create maintenance problems due to gravel being tracked onto the roadway. In accordance with District policy, 7205.4.8, the applicant should be required to pave the driveway its full width and at least 30-feet into the site beyond the edge of pavement of the roadway and install pavement tapers in accordance with Table 2 under District Policy 7205.4.8. 14 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 Cross Access Easements/Shared Access Policy: District Policy 7202.4.1 states that cross access utilizes a single vehicular connection that serves two or more adjoining lots or parcels so that the driver does not need to re-enter the public street system. 6.2 Grand Mogul Drive Access Policy: District Policy 7205.4.1 states that all access points associated with development applications shall be determined in accordance with the policies in this section and Section 7202. Access points shall be reviewed only for a development application that is being considered by the lead land use agency. Approved access points may be relocated and/or restricted in the future if the land use intensifies, changes, or the property redevelops. District Policy 7206.1 states that the primary function of a collector is to intercept traffic from the local street system and carry that traffic to the nearest arterial. A secondary function is to service adjacent property. Access will be limited or controlled. Collectors may also be designated at bicycle and bus routes. Driveway Location Policy (Signalized Intersection): District policy 7206.4.3 requires driveways located on collector roadways near a signalized intersection to be located outside the area of influence; OR a minimum of 440-feet from the signalized intersection for a full-access driveway and a minimum of 220-feet from the signalized intersection for a right-in/right-out only driveway. Dimensions shall be measured from the centerline of the intersection to the centerline of the driveway. Driveway Location Policy (Stop Controlled Intersection): District policy 7206.4.4 requires driveways located on collector roadways near a STOP controlled intersection to be located outside of the area of influence; OR a minimum of 150-feet from the intersection, whichever is greater. Dimensions shall be measured from the centerline of the intersection to the centerline of the driveway. Successive Driveways: District policy 7206.4.5 Table 1 requires driveways located on collector roadways with a speed limit of 25 MPH and daily traffic volumes greater than 100 VTD to align or offset a minimum of 245-feet from any existing or proposed driveway. Driveway Width Policy: District policy 7206.4.6 restricts high-volume driveways (100 VTD or more)to a maximum width of 36-feet and low-volume driveways (less than 100 VTD)to a maximum width of 30-feet. Curb return type driveways with 30-foot radii will be required for high-volume driveways with 100 VTD or more. Curb return type driveways with 15-foot radii will be required for low-volume driveways with less than 100 VTD. Driveway Paving Policy: Graveled driveways abutting public streets create maintenance problems due to gravel being tracked onto the roadway. In accordance with District policy, 7206.4.6, the applicant should be required to pave the driveway its full width and at least 30-feet into the site beyond the edge of pavement of the roadway and install pavement tapers in accordance with Table 2 under District Policy 7206.4.6. Minor Improvements Policy: District Policy 7203.3 states that minor improvements to existing Highways adjacent to a proposed development may be required. These needed transportation facilities are to correct deficiencies or replace deteriorated facilities. Included are sidewalk and/or bike lane construction or replacement (with physical buffers if missing and needed); construction of transitional sidewalk segments; crosswalk construction or replacement; curb and gutter construction or replacement; repair, replacement or expansion of curb extensions; replacement of unused driveways with curb, gutter, sidewalk, repair or addition of traffic calming or speed mitigation features; installation or reconstruction of pedestrian ramps; pavement repairs; signs, motor vehicle, pedestrian and bicycle traffic control devices; and other similar items. The current version of PROWAG will determine the applicable accessibility requirements for alterations and elements added to existing streets. ACHD staff is responsible for identifying the minor improvements that would be proportionate to the size and complexity of the development. 15 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 7. Private Roads 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. 8. Tree Planters Tree Planter Policy: Tree Planter Policy: The District's Tree Planter Policy prohibits all trees in planters less than 8-feet in width without the installation of root barriers. Class II trees may be allowed in planters with a minimum width of 8-feet, and Class I and Class III trees may be allowed in planters with a minimum width of 10-feet. 9. Landscaping Landscaping Policy: A license agreement is required for all landscaping proposed within ACHD right-of-way or easement areas. Trees shall be located no closer than 10-feet from all public storm drain facilities. Landscaping should be designed to eliminate site obstructions in the vision triangle at intersections. District Policy 5104.3.1 requires a 40-foot vision triangle and a 3-foot height restriction on all landscaping located at an uncontrolled intersection and a 50-foot offset from stop signs. Landscape plans are required with the submittal of civil plans and must meet all District requirements prior to signature of the final plat and/or approval of the civil plans. 10. 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. 16 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 G. Attachments Attachment A: Executive Summary of Black Cat Industrial TIS 17 DRAFT Black Cat East R&A/ MER24-0094 / H-2024-0047 Section 1 Executive Summary Black Cat Industrial Development TIS March 2022 Executive Summary EXECUTIVE SUMMARY The Black Cat Industrial Park is located on the west side of Black Cat Road approximately% mile south of Franklin Road. The proposed site is currently vacant farmland and consists of approximately 121 acres. The development will be annexed into the City of Meridian. The development plan proposes to build approximately 2,214,000 square feet of industrial park uses with an anticipated buildout year of approximately 2030. The TIS resulted in the following findings and recommendations. FINDINGS Existing Conditions ■ The study evaluated two off-site intersections and two off-site roadway segments during the AM and PM peak period of a typical weekday. ■ All study intersections were found to operate at acceptable operating standards during the existing weekday AM and PM peak hours. o Franklin Road/McDermott Road: The northbound and southbound approaches at the intersection were found to operate acceptably at LOS E with V/C ratio below the ACHD V/C thresholds. Per ACHD policy,signal warrants were evaluated because the intersection operates at LOS D or worse and identified that the intersection meets traffic signal warrants under existing conditions. It should be noted that the ACHD Master Street Map identifies a multi-lane roundabout at this intersection and that this intersection is currently shown in the 2022-2026 Draft ACHD Five Year Work Plan (FYWP) as part of the Franklin Corridor Improvements for design and construction in the future with no date provided. ■ All study roadway segments operate within the Ada County Highway District (ACHD) volume threshold under existing conditions with the exception of the following: o Franklin Road (Black Cat Road to McDermott Road):The westbound segment volume in the weekday PM peak hour exceeds the ACHD peak hour segment volume threshold for LOS E on a principal arterial. Widening to five lanes is required which is currently shown in the 2022-2026 Draft ACHD Five Year Work Plan for design in 2026 and shown in the ACHD CIP for construction in 2026-2030. ■ While the ACHD segment threshold volume is exceeded, the constraining intersections on either end of this segment at Black Cat Road and McDermott Road operate acceptably and therefore widening of the segment is not required to accommodate the existing traffic demand and not required until mitigations at I2 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary the intersections is required as described in the 2030 background and 2030 total traffic sections. ■ Crash data at the study intersections and roadway segments for the most recent five years of complete data (2016-2020) were analyzed. No crash trends were identified. Year 2030 Background Traffic Conditions ■ Year 2030 background traffic volumes were forecast using 2030 projections by COMPASS which included the SH-16 extension from 1-84 to US 20-26. Inclusion of the SH-16 Phase 2 extension between 1-84 and US 20-26 was included because the extension is currently in final design at ITD and expected to start construction as early as 2022. The projections included traffic growth associated with in-process approved developments as well as future development estimated to be completed by 2030. In general,traffic volumes are projected to grow between 3%and 9% per year, compounded, depending on the location and peak hour with a general average of approximately 5% per year. ■ Year 2030 background traffic conditions found that all the study intersections will operate at acceptable operating standards during the existing weekday AM and PM peak hours with the exception of the following: o Franklin Road/McDermott Road: The northbound and southbound approaches at the intersection were found to have traffic demands that exceed capacity at operate at LOS F during the weekday PM peak hour. The intersection was found to meet traffic signal warrants under existing conditions.The following mitigation was identified: ■ Option 1: Widening of Franklin Road at the Intersections: Widen Franklin Road to five lanes with a center two-way-left-turn lane (TWLTL) for approximately mile either side of McDermott Road to provide for two-stage left-turns from McDermott Road onto Franklin Road. Widening Franklin Road is currently shown in the ACHD CIP for construction in 2026-2030. ■ Option 2: Interim Intersection Improvements: • Installation of an interim traffic signal with only left-turn lanes was not found to mitigate the operation due to the high volume of westbound through traffic in a single lane during the weekday PM peak hour. • Installing a TWLTL would improve operations, but still not accommodate the 2030 background traffic demand. It was estimated to move out the need for mitigation by approximately 2 years to 2029. • Mitigation is estimated to be needed in approximately 2027. ■ It should be noted that the ACHD Master Street Map identifies a multi-lane roundabout at this intersection and that this intersection is currently shown in the I� 3 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary 2022-2026 Draft ACHD FYWP as part of the Franklin Corridor Improvements for design and construction in the future with no date provided. ■ All study roadway segments operate within the ACHD volume threshold under 2030 background conditions with the exception of the same section of roadway as identified under existing conditions: o Franklin Road (Black Cat Road to McDermott Road): The eastbound and westbound movements in the weekday AM and PM peak hours, respectively, exceed the ACHD peak hour volume threshold. Widening to five lanes is required which is currently shown in the 2022-2026 Draft ACHD FYWP for design in 2026 and shown in the ACHD CIP for construction in 2026-2030. ■ While the ACHD segment threshold volume is exceeded, the constraining intersection on the east end of this segment at Black Cat Road operates acceptably and the constraining intersect on the west end of this segment at McDermott Road can be mitigated to operate acceptably and therefore,widening of the segment is not required. Trip Generation ■ The development plan proposes to build approximately 2,214,000 square feet of industrial park uses on approximately 121 acres. ■ The development is estimated to generate a total of approximately 4,700 daily net new trip ends, of these,886 are estimated to occur in the weekday AM peak hour(717 inbound/169 outbound), and 886 are estimated to occur in the weekday PM peak hour (186 inbound /700 outbound). ■ ITD did not require analysis of the Ten Mile Road/1-84 Interchange but did request the number of trips projected to be added to the southbound left-turn movement.Approximately 10 and 42 site generated trips are estimated to be added to the southbound left-turn movement at the interchange during the weekday AM and PM peak hours, respectively. Year 2030 Total Traffic Conditions— Base Option: E-W Collector Access to Black Cat Road ■ The ACHD Master Street Map and City of Meridian Ten Mile Interchange Area Specific Plan (TMASP) call for three collector roadways in the vicinity of the side.These include the following: o East-West Collector: This collector bisects the site at approximately a half mile south of Franklin Road. This collector will be constructed from Black Cat Road to the western boundary of the development. o North-South Collector: This collector is adjacent to the western property line and will ultimately extend north to Franklin Road once other properties develop. This collector I4 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary will be constructed from the East-West Collector to the northern site boundary of the development although an option is evaluated to extend this collector to Franklin Road as part of this development. o Northern East-West Collector: This collector is shown along the northern property line on the ACHD Master Street Map and on the TMASP but to the north of the site property on the TMASP land-use map. Based on discussions by the project team with the City of Meridian, the preference by the City of Meridian is to locate the Northern East-West collector north of the site to avoid an irrigation drain and align with a similar collector on the east side of Black Cat Road. ■ Two access alternatives were evaluated for the site access which include: o Access Alternative 1 (Access A Only): This alternative assumes all access to the development is from Black Cat Road from the East-West Collector Road at Site Access A. o Access Alternative 2 (Access A& B): This alternative assumes a secondary access to the site from Black Cat Road will be at Site Access B. ■ Both off-site study intersections were found to require some level of mitigation under the total traffic conditions during the weekday AM and PM peak hours as described below: o Franklin Road/McDermott Road (Access Alternatives 1&2):Similar to 2030 background conditions, the northbound and southbound stop-controlled movements operate at LOS F and exceed capacity during the weekday PM peak hour. The following mitigation and thresholds were identified: ■ Widening of Franklin Road in the vicinity of the intersection to five lanes with a center TWLTL that can be utilized for two-stage left-turns from McDermott Road onto Franklin Road. Widening Franklin Road is currently shown in the ACHD CIP for construction in 2026-2030. ■ Addition of a center TWLTL does not fully mitigate the intersection operations but result in the need being moved out 1-2 years to a timeframe in which it is reasonably likely ACHD may have Franklin Road widened. ■ The intersection does not operate within ACHD policy V/C thresholds during the shoulder PM peak hour. ■ Installing an interim traffic signal with only left-turn lanes was not found to mitigate the operation due to the high volume of westbound through traffic in a single lane during the weekday PM peak hour. ■ Mitigation is needed in approximately the 2027 timeframe, with added project traffic, at which time approximately 46% (1,018,000 SF) of the site is developed. I� 5 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ If a TWLTL is installed on Franklin Road at the intersection, the mitigation timeframe for widening to five lanes would be moved out to approximately 2028 with approximately 74% (1,636,000 SF) of the site developed. ■ Site traffic is estimated to account for approximately 17.2%and 10.7%of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively. o Franklin Road/Black Cat Road (Access Alternatives 1&2):The intersection operates with a V/C of 1.14 during the PM peak hour, primarily due to the northbound left-turn movement operating with a V/C ratio of 1.15. The following mitigations and thresholds were identified: ■ Restripe the northbound left-turn lane for dual northbound left-turn lanes and modify signal heads as necessary. The design of the intersection already accommodates this restriping. ■ Restripe the westbound left-turn lane for dual westbound left-turn lanes and modify signal heads as necessary. The design of the intersection already accommodates this restriping. ■ Extend the westbound through lane on Franklin Road further west of Black Cat Road to achieve full utilization of the two westbound through lanes. Widening Franklin Road to five lanes between Black Cat Road and McDermott Road is currently shown in the ACHD CIP for construction in 2026-2030. ■ Mitigation is needed in approximately the 2028 timeframe, with added project traffic, at which time approximately 68% (1,502,000 SF) of the site is developed. ■ Site traffic is estimated to account for approximately 25.6%and 18.4%of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively. ■ The site access driveway and on-site study intersections operate acceptably during the total traffic conditions weekday AM and PM peak hours, with the exception of the following: o Black Cat Road/Site Access A(Access Alternatives 1&2):The eastbound approach at the intersection is projected to have demand that exceeds capacity at operates at LOS F. The intersection is also projected to meet traffic signal warrants. The following mitigations and thresholds were identified: ■ Install the following turn lanes: • Eastbound left-turn lane (in addition to eastbound through-right lane) • Northbound left-turn lane • Southbound left-turn lane (not required for traffic volumes) • Southbound right-turn lane Iwr 6 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ Install a traffic signal.The signal spacing meets the ACHD policy of half-mile signal spacing for collector roadways on minor arterials. ■ Mitigation is estimated to be needed in approximately 2025 under Access Alternative 1 with approximately 33% (731,000 SF) of the site developed and 2025-2026 under Access Alternative 2 with approximately 42%(930,000 SF)of the site developed. ■ If a TWLTL is installed on Franklin Road at the intersection, mitigation is estimated to be needed in approximately 2025-2026 under Access Alternative 1 with approximately 44% (974,000 SF) of the site developed and 2026-2027 under Access Alternative 2 with approximately 61%(1,351,000 SF)of the site developed. ■ Site traffic is estimated to account for approximately 61.3%and 47.4%of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively for Access Alternative 1 and 50.1%and 41.4% of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively for Access Alternative 2. o Black Cat Road/Site Access B(Access Alternative 2 Only):The eastbound approach at the intersection is projected to have demand that exceeds capacity and operates at LOS F during the weekday PM peak hour.The intersection is also projected to meet traffic signal warrants.The following turn lanes were identified to mitigate the intersection operations without signalization: ■ Short section of TWLTL to provide for two-stage left-turn movements from Site Access B and for northbound left-turning movements. ■ Southbound right-turn lane (required based on unsignalized warrants) ■ Mitigation is estimated to be needed in approximately 2026-2027 under Access Alternative 2 with approximately 65% (1,439,000 SF) of the site developed. ■ Site traffic is estimated to account for approximately 52.8%and 44.4%of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively. ■ Both off-site study roadway segments have projected traffic demands that exceed the ACHD volume thresholds under 2030 total conditions, including: o Franklin Road (Black Cat Road to McDermott Road): Similar to the 2030 background traffic conditions,the eastbound and westbound movements in the weekday AM and PM peak hours exceed the ACHD peak hour volume threshold. Widening to five lanes is required which is currently shown in the 2022-2026 Draft ACHD FYWP for design in 2026 and shown in the ACHD CIP for construction in 2026-2030. This is an existing need. ■ The segment also requires widening to five lanes in the shoulder peak hour. I7 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ Two options for maintaining acceptable traffic operations on Franklin Road were identified. These include: • Mitigation Option 0 — Improve Intersections: Improve the McDermott Road and Black Cat Road intersections per the mitigation analysis. While the ACHD segment volume threshold would still be exceeded, traffic flow would still occur due to the intersection to the east and west operating acceptably. • Mitigation Option 1 — Extend North-South Collector to Franklin Road: Mitigation Option 1 was evaluated (see report section) which extends the North-South Collector to create a new intersection on Franklin Road (Site Access D). This reduces the impact of site traffic on the half-mile segment between Black Cat Road and the North-South Collector. ■ Site traffic is estimated to account for approximately 25.3%and 14.2%of the 2030 critical peak hour directional traffic during the weekday AM and PM peak hours, respectively. o Black Cat Road (Site Access A to Franklin Road): The southbound and northbound movements in the weekday AM and PM peak hours, respectively, exceed the ACHD peak hour volume threshold. Widening to five lanes is required which is currently shown in the ACHD CIP for construction in 2036-2040. ■ The segment also requires widening to five lanes based on the shoulder peak hour. ■ Two options for maintaining acceptable traffic operations on Franklin Road were identified. These include: • Mitigation Option 0—Improve Intersections: Improve the Black Cat Road, Site Access A, and Site Access B intersections per the mitigation analysis. • Mitigation Option 1 — Extend North-South Collector to Franklin Road: Mitigation Option 1 was evaluated (see following Mitigation Option 1 section) which extends the North-South Collector to create a new intersection on Franklin Road (Site Access D).This significantly reduces the impact of site traffic on the Black Cat Road between Site Access A and Franklin Road. This option results in the 2030 total segment volume still exceeding the two-lane threshold but reduces the peak directional traffic demand by approximately 30 percent. ■ A two-lane highway analysis identified that Black Cat Road is projected to operate with a V/C ratio of approximately 0.69 in the two-lane section outside the areas of the intersections. ■ Widening is estimated to be needed in approximately 2025-2026, with added project traffic, with approximately 43% (960,000 SF) of the site developed. I� 8 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ Site traffic is estimated to account for approximately 76.1%and 56.7%of the 2030 critical peak hour directional traffic volume during the weekday AM and PM peak hours, respectively. ■ All on-site study roadway segments along the East-West Collector (Site Access A) have projected traffic demands under the ACHD volume thresholds for a collector roadway with two lanes (on lane in each direction) under 2030 total conditions with the exception of the following: o Access Alternative 1 ■ East-West Collector (Black Cat Road to Site Access C2): The projected volumes exceed the ACHD threshold for two lanes on a collector roadway.Widening to five lanes is projected to be needed to meet ACHD policy. o Access Alternative 2 ■ East-West Collector (Black Cat Road to Site Access Cl): With Site Access B, the projected volumes exceed the ACHD threshold for two lanes on a collector roadway. Widening to five lanes is projected to be needed to meet ACHD policy. ■ East-West Collector (Site Access C1 to Site Access C2): With Site Access B, the projected volumes exceed the ACHD threshold for two lanes on a collector roadway. Widening to three lanes is projected to be needed to meet ACHD policy. Site Access Evaluation ■ The turn lane analysis using ACHD procedures resulted in turn lane warrants at the following site access streets: o Site Access A/Black Cat Road (Access Alternatives 1 & 2) ■ Southbound right-turn lane (unsignalized and signalized) ■ Storage of 250 feet is recommended ■ Northbound left-turn lane (unsignalized and signalized) ■ Storage of 100 feet is recommended ■ Eastbound left-turn lane (unsignalized and signalized) ■ Storage of 175 feet in the striped left-turn lane is recommended with approximately 200 feet of additional TWLTL through Site Access C1 for a total usable distance of approximately 375 feet to Site Access C1. Under Access Alternative 1, the end of queue is projected to extend approximately 200 feet past Site Access C1 for brief periods in the weekday PM peak hour until one of the following changes occur: o An additional collector connection to Franklin Road to the north or McDermott Road to the east. I� 9 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary o Construction of dual eastbound left-turn lanes along with widening of Black Cat Road between Site Access A and Franklin Road for two northbound through receiving lanes. ■ Southbound left-turn lane (only required when signalized) • Storage of 100 feet (only if signalized) o Site Access B/Black Cat Road (Access Alternative 2) ■ Southbound right-turn lane (unsignalized) • Storage of 100 feet is recommended ■ Two-way-left-turn lane • Storage of 100 feet is recommended to south and north of the intersection. o East-West Collector/Site Access C1 (Access Alternative 1) ■ Westbound left-turn lane (two lane collector&Access Alternative 1 only— not required if five lanes) • TWLTL recommended ■ Westbound right-turn lane (two lane collector&Access Alternative 1 only- not required if five lanes) • Storage of 100 feet is recommended o East-West Collector/Site Access C2 (Access Alternative 1) ■ Westbound left-turn lane (two lane collector&Access Alternative 1 only— not required if five lanes) • TWLTL recommended ■ All site access meet ACHD minimum spacing requirements. ■ Daily trips on the East-West Collector for Access Alternative 1 exceed the ACHD policy of 3,000 daily trips on a collector serving as a single access. ■ The intersection sight distance evaluation identified that adequate intersection sight distance can be achieved at both site access intersection locations on Black Cat Road. Some clearing of vegetation and trimming of trees will be needed to the north of Site Access B. Sight distance was not able to be reviewed for the proposed driveways on the proposed East-West Collector roadway since the collector does not exist at this time. Year 2030 Total Traffic Conditions— Mitigation Option 1: N-S Collector to Franklin Road ■ Due to the lack of ability to widen Franklin Road between Black Cat Road and McDermott Road, extension of the proposed North-South Collector to Franklin Road, in addition to the East-West Collector accessing Black Cat Road, was evaluated as Mitigation Option 1. I10 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ The same two access alternatives were evaluated for the site access to Black Cat Road which include: o Access Alternative 1 (Access A Only): This alternative assumes all access to the development is from Black Cat Road from the East-West Collector Road at Site Access A. o Access Alternative 2 (Access A & B): This alternative assumes a secondary access to the site from Black Cat Road will be at Site Access B. ■ Of the off-site study intersections, only the Franklin Road/McDermott Road intersection was found to require some level of mitigation under the total traffic conditions with Mitigation Option 1 during the weekday AM and PM peak hours as described below: o Franklin Road/McDermott Road (Access Alternatives 1 & 2): Mitigation Option 1 does not change the results at this intersection. See the previous section for findings and recommendations. ■ The site access driveway and on-site study intersections operate acceptably during the total traffic conditions under Mitigation Option 1 during the weekday AM and PM peak hours,with the exception of the following: o Black Cat Road/Site Access A ■ Access Alternative 1: The eastbound approach at the intersection is projected to have demand that exceeds capacity at operates at LOS F. The following mitigations were identified: 0 Install a traffic signal with the following turn lanes: o Eastbound left-turn lane (in addition to eastbound through-right lane) o Northbound left-turn lane o Southbound left-turn lane (not required for traffic volumes) o Southbound right-turn lane ■ Access Alternative 2: The eastbound approach at the intersection is projected to have demand that exceeds capacity at operates at LOS F. The following mitigations were identified: • Option 1-TWLTL: Unsignalized with the following turn lanes: o Two-way-left-turn-lane (TWLTL) on Black Cat Road approximately 100 feet each side of Site Access A o Eastbound left-turn lane (in addition to eastbound through-right lane) I11 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary o Southbound right-turn lane • Option 2 -Traffic Signal: Installation of a traffic signal with the following turn lanes: o Eastbound left-turn lane (in addition to eastbound through-right lane) o Northbound left-turn lane o Southbound left-turn lane (not required for traffic volumes) o Southbound right-turn lane ■ The intersection was found to meet traffic signal warrants under both access alternatives and the signal spacing meets the ACHD policy of half-mile signal spacing for collector roadways on minor arterials. ■ Mitigation is estimated to be needed in approximately 2027 under Access Alternative 1 with approximately 55% (1,218,000 SF) of the site developed and 2028 under Access Alternative 2 with approximately 66% (1,461,000 SF) of the site developed. ■ With the addition of a TWLTL, mitigation is estimated to be needed in approximately 2029 with approximately 88% (1,948,000 SF) of the site developed under Access Alternative 1. The intersection operates acceptably through buildout under Access Alternative 2 ■ Site traffic is estimated to account for approximately 47.0%and 33.5%of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively,for Access Alternative 1 and 35.6%and 28.0%of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively for Access Alternative 2. o Franklin Road/Site Access D (N-S Collector): The northbound approach at the intersection is projected to have demand that exceeds capacity at operate at LOS F during the weekday PM peak hour. The intersection is also projected to meet traffic signal warrants. Installation of a traffic signal with left-turn lanes was found to cause the westbound through movement to exceed capacity during the weekday PM peak hour without widening Franklin Road to add an additional westbound through lane. The following mitigation options were identified: ■ Mitigation Option 1-Traffic signal (3X4): Install a traffic signal with the following lanes: • Second westbound through lane. • Northbound left-turn lane. • Eastbound right-turn lane. I12 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary • The signal was still found to operation with a V/C ratio of 0.93 during the weekday PM peak hour which is above the ACHD policy of<_0.90. ■ Mitigation Option 2-Traffic signal (3XS): Install a traffic signal with the following lanes: • Second eastbound and westbound through lanes. • Northbound left-turn lane • Eastbound right-turn lane ■ Mitigation Option 3 — Multi-Lane Roundabout: Install a multi-Lane roundabout with two through lanes eastbound and westbound and single approach lanes northbound and southbound. ■ Mitigation is estimated to be needed in approximately 2024-2025 with approximately 25% (554,000 SF) of the site developed. ■ With the addition of a TWLTL, mitigation is estimated to be needed in approximately 2026 with approximately 50%(1,107,000 SF)of the site developed, ■ Site traffic is estimated to account for approximately 21.8%and 15.6%of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively. ■ Both off-site study roadway segments continue to have projected traffic demands that exceed the ACHD volume thresholds under 2030 total traffic conditions, but the impacts are significantly reduced with Mitigation Option 1: o Franklin Road (Black Cat Road to Site Access D): Similar to the 2030 background traffic conditions, the eastbound and westbound movements in the weekday AM and PM peak hours exceed the ACHD peak hour volume threshold. Widening to five lanes is required to meet ACHD policy which is currently shown in the 2022-2026 ACHD FYWP for design in 2026 and shown in the ACHD CIP for construction in 2026-2030. This is an existing need. ■ The segment also requires widening to five lanes in the shoulder peak hour based on ACHD segment volume thresholds. ■ The following mitigation options were identified: • Mitigation Option 1-0— Improve Intersections: Improve the Site Access D intersection per the mitigation analysis. This allows the constraint intersections on either end of the segment operate acceptably. o The segment constraint is at the intersections and therefore, with the improvement of the Franklin Road/Site Access D intersection, the segment can accommodate the traffic demand even though it will exceed ACHD policy thresholds.

Black Cat Industrial Development TIS March 2022 Executive Summary • Mitigation Option 1-1 — Limit Development: As described later in this section, with the North-South Collector extended to Franklin Road approximately 2S%-50% (554,000 SF— 1,107,000 SF) of the development is estimated to be possible prior to Site Access D reaching capacity, depending on whether a TWLTL is installed ■ Site traffic is estimated to account for approximately 2.0% and 1.1% of the 2030 critical peak hour directional traffic during the weekday AM and PM peak hours, respectively. o Franklin Road (Site Access D to McDermott Road): Mitigation Option 1 does not change the results at this intersection. Widening to five lanes is required to meet ACHD policy thresholds which is currently shown in the 2022-2026 Draft ACHD FYWP for design in 2026 and shown in the ACHD CIP for construction in 2026-2030. This is an existing need. Following were mitigation options that were identified (see previous section for additional findings, recommendations, and mitigation options): ■ The following mitigation options were identified: • Mitigation Option 1-0— Improve Intersections: Improve the McDermott Road and Site Access D intersections per the mitigation analysis. This allows the constraint intersections on either end of the segment operate acceptably. o The segment constraint is at the intersections and therefore, with the improvement of the Franklin Road/Site Access D and Franklin Road/McDermott Road intersections, the segment can accommodate the traffic demand even though it will exceed ACHD policy thresholds. • Mitigation Option 1-1 — Limit Development: As described later in this section, with the North-South Collector extended to Franklin Road approximately 25%-50% (554,000 SF— 1,107,000 SF) of the development is estimated to be possible prior to Site Access D side street movements reaching capacity and approximately 46% to 74% (1,016,000 SF — 1,636,000 SF) of the development is estimated to be possible prior to the McDermott Road side street movements reaching capacity, depending on whether interim TWLTL center turn lanes are installed. o Black Cat Road (Site Access A to Franklin Road): While addition of Site Access D (North- South Collector) on Franklin Road reduces site traffic on Black Cat Road, the northbound movement in the weekday PM peak hour exceeds the ACHD peak hour volume threshold. Widening to five lanes is required which is currently shown in the ACHD CIP for construction in 2036-2040. ■ The segment also requires widening to five lanes based on the shoulder peak hour. I14 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ The following mitigation options were identified: • Mitigation Option 1-0— Improve Intersections: Improve the Site Access A, and Site Access B intersections per the mitigation analysis. • Mitigation Option 1-1 — Limit Development: As described later in this section, with the North-South Collector extended to Franklin Road approximately 1,518,000 SF of the development is estimated to be possible prior to Black Cat Road reaching the ACHD segment threshold volume with only the East-West Collector accessing the development. ■ If widening is pursued, it is estimated to be needed in approximately 2028, with added project traffic, with approximately 69% (1,518,000 SF) of the site developed. ■ Site traffic is estimated to account for approximately 60.5%and 38.7%of the 2030 critical peak hour directional traffic volume during the weekday AM and PM peak hours, respectively. ■ All on-site study roadway segments along the East-West Collector (Site Access A) have projected traffic demands under the ACHD volume thresholds for a collector roadway with two lanes (one lane in each direction) under both access alternatives. Site Access Evaluation ■ The turn lane analysis using ACHD procedures resulted in turn lane warrants at the following site access streets: o Site Access A/Black Cat Road (Access Alternatives 1 & 2) ■ Southbound right-turn lane (unsignalized and signalized) • Storage of 100 feet is required, but 250 feet is recommended to accommodate trucks. ■ Northbound left-turn lane (unsignalized and signalized) • Storage of 100 feet is recommended. This could be striped as a TWLTL in the interim. Under Access Alternative 2, the TWLTL could remain through buildout. ■ Eastbound left-turn lane (unsignalized and signalized) • Storage of 125 feet is required, but 175 feet in the striped left-turn lane is recommended with approximately 200 feet of additional TWLTL through Site Access C1 for a total usable distance of approximately 375 feet to Site Access C1. ■ Southbound left-turn lane (only required when signalized) • Storage of 100 feet (only if signalized) I15 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary o Site Access B/Black Cat Road (Access Alternative 2) ■ Two-way-left-turn lane • Storage of 100 feet is recommended to south and north of the intersection. ■ Southbound right-turn lane is not warranted but should be considered to service truck if not signed to prohibit trucks from using the access. If constructed storage of 100 feet is recommended. ■ All site access meet ACHD minimum spacing requirements. ■ Daily trips on the East-West Collector, North-South Collector, and site accesses are under ACHD policy thresholds. ■ The intersection sight distance evaluation identified that adequate intersection sight distance can be achieved at Site Access D on Franklin Road. See previous findings for Site Access A, Site Access B and the driveways on the collectors. RECOMMENDATIONS Based on the report's analyses and evaluation findings, recommendations were developed accordingly for time scenario's conditions. Year 2021 Existing Traffic Condition Mitigations (Without the Proposed Development) The following mitigations are recommended to accommodate the year 2021 traffic volumes. ■ Franklin Road (Black Cat Road to McDermott Road): In order to meet ACHD policy, widening of Franklin Road to five lanes with a center turn lane per the ACHD CIP (2026-2030) is required. o While the ACHD segment threshold volume is exceeded, the constraining intersections on either end of this segment at Black Cat Road and McDermott Road operate acceptably and therefore widening of the segment is not required to accommodate the existing traffic demand and not required until mitigations at the intersections is required as described in the 2030 background and 2030 total traffic sections. Year 2030 Background Traffic Condition Mitigations (Without the Proposed Development) The following additional mitigations are required under background traffic conditions above those identified for existing conditions: ■ Franklin Road/McDermott Road: Widening of Franklin Road to five lanes with a center left-turn lane that can be utilized for two-stage left-turns from McDermott Road onto Franklin Road. This widening would only be required at the intersection and is expected to extend approximately I16 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary mile each direction. Widening Franklin Road is currently shown in the ACHD CIP for construction in 2026-2030. o Mitigation is needed in approximately 2027 without the development of the site and approximately 2026 with approximately 46% (1,016,000 SF) of the site developed. o Installing a center TWLTL at the intersection would provide additional interim capacity at the intersection and was found to push out the need two years in the 2030 total traffic conditions. Year 2030 Total Traffic Mitigations— Base Option: E-W Collector Access to Black Cat Road The following mitigations are required under 2030 total traffic conditions: ■ Off-Site Mitigations Required for Access Alternatives 1 &2 o Franklin Road/McDermott Road: The following mitigations and thresholds were identified: ■ Install an interim TWLTL section on Franklin Road to provide for a two-stage left- turn movement. ■ If a TWLTL is installed on Franklin Road at the intersection, the mitigation timeframe for widening to five lanes would be moved out to approximately 2028 with approximately 74% (1,636,000 SF) of the site developed. ■ Site traffic is estimated to account for approximately 17.2%and 10.7%of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively. o Franklin Road/Black Cat Road: The following mitigations are projected to be necessary: ■ Restripe the northbound left-turn lane and westbound left-turn lane for dual northbound left-turn lanes and modify signal heads as necessary. The design of the intersection already accommodates this restriping. ■ Extend the westbound through lane on Franklin Road further west of Black Cat Road to achieve full utilization of the two westbound through lanes. Widening Franklin Road to five lanes between Black Cat Road and McDermott Road is currently shown in the ACHD CIP for construction in 2026-2030. ■ Mitigation is needed in approximately the 2028 timeframe, with the addition of site traffic, at which time approximately 68% (1,312,000 SF) of the site is developed. ■ Site traffic is estimated to account for approximately 2S.6%and 18.4%of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively. I17 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary o Black Cat Road (Site Access A to Franklin Road): Widening to five lanes is required to meet ACHD policy and is currently shown in the ACHD CIP for construction in 2036-2040. Due to widening not being possible in the near-term due to lack of right-of-way, implement one of the following options: ■ Mitigation Option 0 — Improve Intersections: Improve the Black Cat Road, Site Access A, and Site Access B intersections per the mitigation analysis. ■ Mitigation Option 1—Extend North-South Collector to Franklin Road: Mitigation Option 1 was evaluated (see report section) which extends the North-South Collector to create a new intersection on Franklin Road (Site Access D). This significantly reduces the impact of site traffic on the Black Cat Road between Site Access A and Franklin Road. ■ Mitigation is estimated to be needed in approximately 2025-2026, with the addition of site traffic, under either access alternative with approximately 43% (960,000 SF) of the site developed. ■ Site traffic is estimated to account for approximately 76.1%and 56.7%of the 2030 critical peak hour directional traffic during the weekday AM and PM peak hours, respectively. o Franklin Road (Black Cat Road to McDermott Road): In order to meet ACHD policy, widening of Franklin Road to five lanes with a center turn lane per the ACHD CIP (2026- 2030) is required. Due to widening not being possible in the near-term due to lack of right- of-way, implement one of the following options: ■ Mitigation Option 0— Improve Intersections: Improve the McDermott Road and Black Cat Road intersections per the mitigation analysis. ■ Mitigation Option 1—Extend North-South Collector to Franklin Road: Mitigation Option 1 was evaluated (see report section) which extends the North-South Collector to create a new intersection on Franklin Road (Site Access D). This reduces the impact of site traffic on the half-mile segment between Black Cat Road and the North-South Collector. ■ With intersection improvements, the segment is estimated to have a volume/capacity ratio of 1.13 under 2030 Total Traffic conditions. Capacity of the segment as a two-lane highway is estimated to be reached in approximately 2028 with approximately 79% (1,760,000) of the site developed. ■ Site traffic is estimated to account for approximately 25.3%and 14.2%of the 2030 critical peak hour directional traffic during the weekday AM and PM peak hours, respectively. I18 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ On-Site Mitigations Needed for Access Alternatives 1 (East-West Collector Only Access) o Black Cat Road/Site Access A(East-West Collector): ■ Consider installation of an interim TWLTL segment on Black Cat Road to provide for a two-stage left-turn movement from the East-West Collector onto Black Cat Road. ■ Construct the following turn lanes: • Eastbound left-turn lane with 175 feet of storage with an additional 200 feet in the TWLTL on the East-West Collector(in addition to the eastbound through-right lane). The estimated 95t" percentile queue for Access Alternative 1 at buildout will extend beyond Site Access C1 for brief periods in the PM peak hour.Therefore,the following additional widening is recommended Access Alternative 1: o Design for dual eastbound left-turn lanes with 175' of storage to be installed once Black Cat Road is widened to five lanes. This is not needed with future extension of the North-South Collector to Franklin Road and likely not needed with the future extension of the East-West Collector to McDermott Road. The East-West Collector intersection approach should be configured as follows (north to south): ■ Two westbound through lanes(assumes five-lane section). ■ Eastbound left-turn lane. ■ Eastbound 2nd left-turn lane (striped out until Black Cat Road is widened). ■ Eastbound through-right lane. • Northbound left-turn lane (100 feet of storage). • Southbound left-turn lane (required for signal operation only — 100 feet of storage) • Southbound right-turn lane (250 feet of storage). ■ Mitigation is estimated to be needed in approximately 2025 under Access Alternative 1 with 33% (731,000 SF) of the site developed. If a TWLTL is installed on Franklin Road at the intersection, mitigation is estimated to be needed in I19 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary approximately 2025-2026 under Access Alternative 1 with 44%(974,000 SF)of the site developed. ■ Site traffic is estimated to account for approximately 61.3%and 47.4%of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively for Access Alternative 1. o East-West Collector (Black Cat Road to Site Access C2): Construct as five lanes to meet ACHD segment volume policy. No additional turn lanes are required at Site Access C1 or C2 with five lanes. Note that the daily trips on the East-West Collector will exceed the ACHD policy threshold of 3,000 until a future extension of the collector system is made. o East-West Collector (Site Access C2 to North-South Collector): Construct per ACHD requirements. Only two lanes are needed to meet ACHD policy, but three lanes should be considered to accommodate future extension of both roadways. o East-West Collector/Site Accesses C1-C8: No turn lanes are warranted at the site accesses to the East-West Collector with implementation of recommendations for the East-West Collector between Black Cat Road and Site Access C2 above. ■ Access Alternative 2 (Site Access B and Site Access A) o Black Cat Road/Site Access A(East-West Collector): ■ Install a traffic signal and construct the following turn lanes: • Eastbound left-turn lane with 175 feet of striped storage (in addition to the eastbound through-right lane). • Northbound left-turn lane (100 feet of storage). • Southbound left-turn lane (required for signal operation only — 100 feet of storage). • Southbound right-turn lane (250 feet of storage). • Mitigation is estimated to be needed in approximately 2025-2026 under Access Alternative 2 with approximately 42% (930,000 SF) of the site developed. If a TWLTL is installed on Black Cat Road Franklin Road at the intersection, mitigation is estimated to be needed in approximately 2026 under Access Alternative 2 with approximately 61% (1,351,000 SF) of the site developed. • Site traffic is estimated to account for approximately 50.1% and 41.4% of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively for Access Alternative 2. I20 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary o Black Cat Road/Site Access B (Access Alternative 2 Only): ■ Construct the following turn lanes: • Short section of TWLTL to provide for two-stage left-turn movements from Site Access B and for northbound left-turning movements. • Southbound right-turn lane with 100 feet of storage (required based on unsignalized warrants) ■ Mitigation is estimated to be needed in approximately 2026-2027 under Access Alternative 2 with approximately 65% (1,439,000 SF) of the site developed. ■ Site traffic is estimated to account for approximately 52.8%and 44.4%of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively. o East-West Collector(Black Cat Road to Site Access Cl): Construct to five lanes to meet ACHD policy. o East-West Collector (Site Access C1 to Site Access C2): Construct to three lanes to meet ACHD policy. o East-West Collector (Site Access C2 to North-South Collector): Construct per ACHD requirements. Only two lanes are needed to meet ACHD policy, although three lanes should be considered to accommodate future extension of both roadways. o East-West Collector/Site Accesses C1-C8: No turn lanes are warranted at the site accesses to the East-West Collector with implementation of recommendations for the East-West Collector between Black Cat Road and Site Access C2 above. All Site Accesses Construct all accesses to the development with the following considerations: ■ All access driveways within the development should be constructed with one travel lane in each direction. ■ Site driveways with access to public streets should provide sufficient stacking distance for a minimum of two passenger vehicles or one truck (50 feet) to ensure acceptable operation and accommodate larger vehicles, including utility service and delivery vehicles. ■ Site accesses along Black Cat Road should match the existing grade or be higher at the intersection to ensure the best possible sight distance. ■ All accesses and internal streets should be designed to provide adequate intersection site distance and signing and building placements should be checked to ensure they do not interfere with intersection sight distance. ■ Site accesses are assumed to match the existing grade of the connected roadway at the intersection and back at least one car length. Significant changes to the approach grade could impact the sight distances. I21 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ Shrubbery, weeds, and landscaping near the internal intersections and site access points should be maintained to ensure adequate sight distance. ■ In areas where roadways are widened, care should be taken to ensure adequate grades and intersection sight distance is maintained. Year 2030 Total Traffic Mitigations— Mitigation Option 1: N-S Collector to Franklin Road The extension of the north-south collector to Franklin Road reduces traffic demand on Black Cat Road, Franklin Road between Black Cat Road and Site Access D (North South Collector), and on the East-West Collector. But it introduces a new intersection on Franklin Road that requires improvements to Franklin Road. The following mitigations are required under 2030 total traffic conditions with Mitigation Option 1. ■ Franklin Road/McDermott Road (Access Alternatives 1 & 2): Mitigation Option 1 does not change the results at this intersection. See previous section for recommendations. ■ Black Cat Road/Site Access A: o Access Alternative 1: Install a traffic signal with the following turn lanes: ■ Eastbound left-turn lane with approximately 175 feet of storage (in addition to eastbound through-right lane). ■ Northbound left-turn lane with 100 feet of storage. ■ Southbound left-turn lane (not required for traffic volumes). ■ Southbound right-turn lane with approximately 250 feet of storage. o Access Alternative 2: The following mitigations were identified: ■ Option 1 -TWLTL on Black Cat Road: • TWLTL on Black Cat Road with approximately 100 feet of storage each side of the intersection. • Eastbound left-turn lane with 175 feet of storage (in addition to eastbound through-right lane) • Southbound right-turn lane with a minimum of 100 feet of storage. Approximately 250 feet should be considered to accommodate a future signal if needed and large trucks. ■ Option 2 —Traffic Signal: Traffic Signal with the same turn lanes as listed above for Access Alternative 1. o The intersection was found to meet traffic signal warrants under both access alternatives and the signal spacing meets the ACHD policy of half-mile signal spacing for collector roadways on minor arterials. I22 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary o Mitigation is estimated to be needed in approximately 2027 under Access Alternative 1 with 55% (1,218,000 SF) of the site developed and 2028 under Access Alternative 2 with approximately 66% (1,461,000 SF) of the site developed. o With the addition of a TWLTL, mitigation is estimated to be needed in approximately 2029 with approximately 88% (1,948,000 SF) of the site developed under Access Alternative 1. The intersection operates acceptably through buildout under Access Alternative 2. o Site traffic is estimated to account for approximately 47.0% and 33.5% of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively, for Access Alternative 1 and 35.6% and 28.0% of the 2030 total peak hour traffic during the weekday AM and PM peak hours, respectively for Access Alternative 2. ■ Franklin Road/Site Access D (N-S Collector): The following mitigation options were identified: o Mitigation Option 1-Traffic signal (3X4): Install a traffic signal with the following lanes: ■ Second westbound through lane. ■ Northbound left-turn lane. ■ Eastbound right-turn lane. ■ The signal was still found to operation with a V/C ratio of 0.93 during the 2030 weekday PM peak hour which is above the ACHD policy of<_0.90. o Mitigation Option 2-Traffic signal (3X5): Install a traffic signal with the following lanes: ■ Second eastbound and westbound through lanes. ■ Northbound left-turn lane. ■ Eastbound right-turn lane. o Mitigation Option 3—Multi-lane Roundabout: Install a multi-Lane roundabout with two through lanes eastbound and westbound and single approach lanes northbound and southbound. o Mitigation is estimated to be needed in approximately 2024-2025 with approximately 25% (554,000 SF) of the site developed. o With the addition of a TWLTL on Franklin Road at the intersection, mitigation is estimated to be needed in approximately 2026 with approximately 50% (1,107,000 SF) of the site developed o Site traffic is estimated to account for approximately 21.8% and 15.6% of the 2030 total entering peak hour traffic during the weekday AM and PM peak hours, respectively. ■ Franklin Road (Black Cat Road to Site Access D): The segment constraint is at the intersections and therefore, with the improvement of the Franklin Road/Site Access D intersection, the segment can accommodate the traffic demand even though it will exceed ACHD policy thresholds. I23 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary o Site traffic is estimated to account for approximately 2.0% and 1.1% of the 2030 critical peak hour directional traffic during the weekday AM and PM peak hours, respectively. ■ Franklin Road (Site Access D to McDermott Road): Mitigation Option 1 does not change the results on this segment. The segment constraint is at the intersections and therefore, with the improvement of the Franklin Road/Site Access D intersection and the Franklin Road/McDermott Road intersection, the segment can accommodate the traffic demand even though it will exceed ACHD policy thresholds. o With intersection improvements, the segment is estimated to have a volume/capacity ratio of 1.13 under 2030 Total Traffic conditions. Capacity of the segment as a two-lane highway is estimated to be reached in approximately 2028 with approximately 79% (1,760,000) of the site developed. o Site traffic is estimated to account for approximately 25.3%and 14.2%of the 2030 critical peak hour directional traffic during the weekday AM and PM peak hours, respectively. ■ Black Cat Road (Site Access A to Franklin Road): While the addition of the Site Access D (North- South Collector) on Franklin Road reduces site traffic on Black Cat Road, the northbound movement in the weekday PM peak hour exceeds the ACHD peak hour volume threshold. Due to the lack of right-of-way for widening as an option to widening, improving the intersections at Site Access A and Site Access B will ensure the traffic demand is accommodated without widening to five lanes. o If widening is considered,widening is estimated to be needed in approximately 2028,with added project traffic, with approximately 69% (1,518,000 SF) of the site developed. o Site traffic is estimated to account for approximately 60.5%and 38.7%of the 2030 critical peak hour directional traffic volume during the weekday AM and PM peak hours, respectively. ■ All on-site study roadway segments along the East-West Collector (Site Access A) have projected traffic demands under the ACHD volume thresholds for a collector roadway with two lanes (one lane in each direction) under both access alternatives. Potential Mitigation Phasing Based on the incorporation of the North-South Collector extension into the Base Scenario with Access Alternative 2 (Site Access B) in order to reduce impacts of site traffic on Franklin Road and Black Cat Road the following phasing could be considered. ■ Phase 1- Initial Site Buildout: o Black Cat Road/Site Access A: Install as an unsignalized intersection with the following turn lanes: I24 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary ■ Two-way-left-turn lane on Black Cat Road that could be converted to northbound and southbound left-turn lanes if needed. ■ Southbound right-turn lane (see turn lane warrants analysis). ■ Eastbound left-turn lane. o Black Cat Road/Site Access B: Construct the site with Site Access B (Alternative 2) ■ Install a short section of two-way-left-turn lane on Black Cat Road. ■ Sign for no trucks or install as southbound right turn lane. East-West Collector: Construct the East-West Collector with three lanes between Black Cat Road and Site Access C1 to provide for left-turn lane storage at Black Cat Road. ■ Phase 2-Approximately 960,000 SF of Development(Black Cat Road Two-Lane Threshold): o Franklin Road/Site Access D(North South Collector): Extend the north-south collector to Franklin Road with the following improvements: ■ Option 1-Traffic signal: Install a traffic signal with the following additional lanes: • Eastbound and westbound left-turn lane lanes. • Second eastbound and westbound through lanes that taper down to the existing two lanes either side of the new intersection. • Northbound left-turn lane ■ Option 2 - Multi-lane Roundabout: Install a roundabout with two through lanes in the eastbound and westbound directions and single lane approaches northbound and southbound. o Franklin Road/McDermott Road TWLTL: Install a TWLTL section on Franklin Road at McDermott Road intersection. ■ Phase 3-Approximately 1.5-2.0 Million SF of Development: o Black Cat Road/Site Access A (East-West Collector): Evaluate the Site Access A intersection and signalize the intersection, if necessary. This approach to phasing improvements provides intersection improvements that allow Franklin Road to accommodate traffic demand through approximately 2028(approximately 74%of the site developed and occupied) and allows Black Cat Road to accommodate the entire development. Even though both roadways will have volumes that exceed ACHD policy, traffic flow will still occur due to the intersections 25 Kittelson&Associates,Inc. Black Cat Industrial Development TIS March 2022 Executive Summary operating acceptably. Given the ACHD CIP has Franklin Road widening in the 2026-2030 timeframe, this phasing could result in Franklin Road being widened at about the time it is estimated to reach capacity in approximately 2028, therefore accommodating full site development. This potential phasing approach is illustrated in Exhibit E-1.
