ATTACHMENT SEPA CASE NUMBER 8329 Findings of Fact 1. This Mitigated Determination of Non Significance is based on the project as proposed and the impacts and potential mitigation measures reflected in the following environmental documents: Environmental Checklist (dated May 22, 2002, prepared by Skillings-Connolly, Inc.) Traffic Impact Analysis (dated August 22, 2002, prepared by Skillings-Connolly, Inc.) Preliminary Storm Drainage and Erosion Control Report (dated September 2002, prepared by Skillings-Connolly) 2. The traffic impact analysis submitted as part of the subdivision application indicates that the project will generate 1034 vehicles per day of average weekday traffic, with a PM peak of 109 vehicles per hour. The project would not decrease the level of service at all but one of the intersections studied, including the following intersections: State Routes 507 and 510 (Yelm Avenue and First Street) Rhoton Road and N.P. Road N.P. Road and Wilkenson Road The two entrances into the subdivision and Wilkenson Road The level of service at Railway Road and First Street would decrease from LOS B to LOS C. The traffic impact analysis recommends that payment of the Transportation Facility Charge as required pursuant to Chapter 15.40 Yelm Municipal Code will mitigate traffic impacts identified in the report. 3. Canal Road currently intersects Wilkerson Road at an angle of approximately 50 degrees, which does not provide safe sight distance for vehicles entering Wilkerson Road from Canal Road. An additional 1034 weekday trips added to Wilkerson Road, almost all of which will be traveling southbound past the intersection with Canal Road, is a significant impact to traffic safety which can be mitigated through the realignment of the Canal Road intersection. 4. The Yelm School District has adopted a school mitigation requirement based on the demand that new residential units create for additional school services and facilities. Additional demands on the school system will be mitigated through the requirement that the developer enter into a mitigation agreement with the District. 5. The proposed 507|510 Alternative Route is identified to bisect the subject property. The Alternative Route is a proposed replacement for State Routes 507 and 510 through the City of Yelm, creating a route for regional traffic to avoid the City core and local access traffic. The Alternative Route has been identified, an Environmental Assessment has been prepared, and a Finding of No Significant Impact has been issued. A public process was used to identify the proposed route and the Comprehensive Plan was updated to adopt the route as part of the transportation system in the City. Yelm is currently attempting to obtain funding for preliminary engineering and right-of-way acquisition. The creation of residential lots within the proposed right-of-way of the Alternative Route is a significant adverse impact. Pursuant to Section 197-11-330 (1)(c) WAC, these impacts can be mitigated through the subdivision review process and the application of existing policies and regulations. Conclusions of Law and Mitigation Measures 1. The proposal will have a significant impact on the transportation system of the City of Yelm which will be mitigated through the imposition of the Transportation Facility Charge as required in Chapter 15.40 Yelm Municipal Code. The proponent shall mitigate transportation impacts based on the new residential p.m. peak hour trips generated by the project. The Transportation Facility Charge (TFC) shall be based on 1.01 new peak hour trips per residential unit. The proponent will be responsible for a TFC of $757.50 per dwelling unit which is payable at time of building permit. 2. Prior to final subdivision approval, the developer shall realign Canal Road with Wilkerson to meet City Standards for intersections. Improvements to the intersection shall include core road improvements. 3. The proposal will have a significant impact on the Yelm School District which will be mitigated through the negotiation of a school mitigation agreement with the Yelm School District. Prior to final subdivision approval, the proponent shall submit to the City of Yelm a signed school mitigation agreement between the developer and the Yelm School District.
