The subject site is located across four parcels addressed as 615 and 617 Williams Ave S (APNs 1723059069, 1723059136, 1823059115, and 1823059282. The four (4) parcels total 1.34 acres in area. The three (3) southern -most parcels are located in the Center Downtown (CD) zoning district and C ommercial Mixed Use (CMU) Comprehensive Plan Land Use Designation. The northern-most parcel is located in the Residential-14 (R-14) zone and Residential High Density (RHD) Comprehensive Plan Land Use Designation. All four (4) parcels are located in the City Center Sign Area overlay and Urban Design District A overlay districts. The site is developed with an existing multi -family building located at 615 Williams S and a standalone billboard at 617 Williams S. The ground floor of the proposed building would consist of 57 stalls of structured parking, a lobby, and back of house spaces. The five (5) floors above would include 145 affordable housing units and various amenity spaces. Approximately 45 surface parking stalls would be located along the north side of the site. Primary vehicle access to the site is proposed via a driveway of Williams Ave S, with emergency access provided via a secondary controlled-access driveway off of S Grady Way. A pedestrian promenade is proposed along the east side of the site connecting S Grady Way to the Burnett Linear Park west of the site. Frontage improvements including a sidewalk, planter strip, and curb and gutter are proposed along S Grady Way and Williams Ave S. The applicant has submitted a transportation impact analysis, geotechnical report, arborist report, and technical information report with the application. Transportation Concurrency Test – Watershed Apartments Page 2 of 4 September 15, 2021 The proposed development would generate approximately 710 net new average weekday daily trips. During the weekday AM peak hour, the project would generate approximately 50 net new trips (14 inbound and 36 outbound). During the weekday PM peak hour, the project would generate approximately 62 net new trips (38 inbound and 24 outbound). The proposed project passes the City of Renton Traffic Concurrency Test per RMC 4-6-070.D as follows: Traffic Concurrency Test Criteria Pass Implementation of citywide Transportation Plan Yes Within allowed growth levels Yes Project subject to transportation mitigation or impact fees Yes Site specific street improvements to be completed by project Yes Traffic Concurrency Test Passes Evaluation of Test Criteria Implementation of citywide Transportation Plan: The City’s investment in completion of the forecast traffic improvements is 130% of the scheduled expenditure through 2020. Within allowed growth levels: The citywide traffic concurrency trip capacity for concurrency with the city adopted model for 2021 is 1,158 trips, which provides sufficient capacity to accommodate approximately 62 additional trips from this project. A resulting 1,096 trips are remaining. Project subject to transportation mitigation or impact fees: The project will be subject to transportation impact fees at time of building permit for the project. Site specific street improvements to be completed by project: The project will be required to complete frontage street improvements prior to Certificate of Occupancy. Any additional off-site improvements identified through SEPA or land use approval will also be completed prior to Certificate of Occupancy. Background Information on Traffic Concurrency Test for Renton The City of Renton Traffic Concurrency requirements for proposed devel opment projects are covered under Renton Municipal Code (RMC) 4-6-070. The specific concurrency test requirement is covered in RMC 4-6-070.D, which is listed for reference: Transportation Concurrency Test – Watershed Apartments Page 3 of 4 September 15, 2021 D. CONCURRENCY REVIEW PROCESS: 1. Test Required: A concurrency test shall be conducted by the Department for each nonexempt development activity. The concurrency test shall determine consistency with the adopted Citywide Level of Service Index and Concurrency Management System established in the Transportation Element of the Renton Comprehensive Plan, according to rules and procedures established by the Department. The Department shall issue an initial concurrency test result describing the outcome of the concurrency test. Transportation Concurrency Test – Watershed Apartments Page 4 of 4 September 15, 2021 2. Written Finding Required: Prior to approval of any nonexempt development activity permit application, a written finding of concurrency shall be made by the City as part of the development permit approval. The finding of concurrency shall be made by the decision maker with the authority to approve the accompanying development permits required for a development activity. A written finding of concurrency shall apply only to the specific land uses, densities, intensities, and development project described in the application and development permit. 3. Failure of Test: If no reconsideration is requested, or if upon reconsideration a project fails the concurrency test, the project application shall be denied by the decision maker with the authority to approve the accompanying development activity permit application. The Concurrency Management System established in the Transportation Element on page XI -65 of the Comprehensive Plan states the following: Based upon the test of the citywide Transportation Plan, consideration of growth levels included in the LOS-tested Transportation Plan, payment of a Transportation Mitigation Fee, and an application of site specific mitigation, development will have met City of Renton concurrency requirements.
