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 15, 2003, prepared by Parametrix) Traffic Impact Analysis (dated August 18, 2003, prepared Transportation Engineering Northwest) Preliminary Storm Drainage and Erosion Control Report (dated May 2003, prepared by Parametrix) 2. The traffic impact analysis (TIA) submitted as part of the subdivision application indicates that the project will generate 1,960 vehicle trips per day, with a PM peak of 205 vehicles per hour. The TIA indicated that: The intersection of West Yelm Avenue (SR 510) and Cullens Road will be at Level of Service (LOS) F with an average delay of 66 seconds on Yelm Avenue in 2008, assuming a baseline annual growth rate of 4%. Southbound on Cullens entering Yelm Avenue will be a LOS F with an average delay of less than 100 seconds. The project will increase wait times to over 100 seconds in each instance. The intersection of West Yelm Avenue and Killion Road will be LOS E (LOS F southbound on Killion) in 2008 and the project will increase the average delay slightly. Frontage improvements will be constructed along Killion Road and Cullens Road. Killion Road and Cullens Road will be widened to 24 feet from the entrances to the subdivision to the improved roadway. 3. The City of Yelm has adopted a concurrency management system as required by the Growth Management Act. Chapter 15.40 YMC (Concurrency Management) is designed to ensure that the improvements required to support development are available at the time of development. A concurrency determination may be issued for a proposal as it relates to transportation issues when: the development provides on-site frontage improvements; the project makes off-site improvements as necessary to provide for the safe movement of traffic; and the project makes a contribution to projects identified the six year transportation improvement program in the form of a Transportation Facilities Charge. The Growth Management Act at Section 36.70.070 (6)(b) states that a finding of concurrency can be issued when required improvements are in place at the time of development or that a financial commitment is in place to complete the improvements or strategies within six years. 4. Improvements to West Yelm Avenue, including a two way center turn lane, is listed as a project on the 2003 - 2008 Transportation Improvement Program. West Yelm Avenue is a State Highway (SR 510). There is no financial commitment currently in place to complete the improvement. Improvements to Cullens Road and Killion Road at their intersection with West Yelm Avenue (SR 510) are listed as projects on the 2003 - 2008 Transportation Improvement Program. There is no financial commitment currently in place to complete the improvement. 5. 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.  Conclusions of Law and Mitigation Measures 1. The developer 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 of Phase I of the proposal, the following transportation improvements shall be complete: The developer shall widen Cullens Road from the subdivision entrance to West Yelm Avenue to a width of 24 feet. The developer is solely responsible for the expense of this improvement. At its intersection with West Yelm Avenue, Cullens Road shall be widened to include a northbound lane from West Yelm Avenue, a left turn lane onto West Yelm Avenue, and a straight-through/right turn lane onto West Yelm Avenue. The addition of turn lanes is a partial intersection improvement to mitigate immediate impacts of the development and is based on the developers share of the full intersection improvement. Traffic Facilities Charges shall be credited towards this improvement. At its intersection with Cullens Road, West Yelm Avenue shall be widened to include an eastbound left turn lane at least 125 feet in length. The addition of a turn lane is a partial intersection improvement to mitigate immediate impacts of the development and is based on the developers share of the full intersection improvement. Traffic Facilities Charges shall be credited towards this improvement. Prior to final subdivision approval of Phase II of the proposal, the following transportation improvements shall be complete: The developer shall widen Killion Road from the subdivision entrance to West Yelm Avenue to a width of 24 feet.

The addition of a turn lane is a partial intersection improvement to mitigate immediate impacts of the development and is based on the developers share of the full intersection improvement. Traffic Facilities Charges shall be credited towards this improvement. The City may defer this improvement at the time Phase III is submitted for final subdivision approval based on other development activity impacting the Killion Road intersection with West Yelm Avenue. 3. The developer shall enter into an agreement with the Yelm School District to mitigate project impacts to the school district.
