DO NOT PUBLISH BELOW THIS LINE Publishetl: Nisqually Valley News, Fritlay, March 25, 20D5 Postetl in public areas: Tuestlay, March 22, 2005 Copies to: All agencieslcitizens on SEPA mailing list antl adjacent propetly owners Dept. of Ecology wlcherhlist ATTACHMENT SEPA Case Number 0175 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 October 15, 2004, prepared by Parametriz) • Traffic Impact Analysis (datetl August 25, 2004, prepared by Jake Traffc Engineering, Inc.) • Traffic Impact Analysis Addendum Letter (dated March 3, 2005, prepared by Jake Traffic Engineering, Inc.) • Preliminary Drainage Report (dated September 2004, prepared by Parametrix) 2. The property was originally two parcels of land approximately 8 ^/: acres and 10 acres in area, the larger of which was occupied by a single family dwelling. A boundary line adjustment in January 2005 changed the parcel configurations, leaving the house on a small parcel and the 17.45 acre parcel subject to this subdivision application. 3. SEPA Rules indicate a project is not categorically exempt from threshold determination requirements if it is a segment of a proposal that includes a series of actions, physically or functionally related to each other, some of which are categorically exempt and some of which are not [WAC 197-11-305 (1)]. 4. The traffic impact analysis (TIA) submitted as part of the subdivision application indicates [hat the project will generate an average of 478 vehicle trips per day, with a PM peak of 51 vehicles per hour. The TIA indicates that, with average growth: The signalized intersection of Yelm Avenue and 1° Street (SR 507 and SR 510) will be at a Level of Service (LOS) E, both with and without project conditions. The intersection of 1" Street and Rhoton Road will be at a LOS C or better with or without project conditions. The intersection of Railway Road SE and Middle Road will be at a LOS C or better with or without project conditions. The intersection of 100'" Way and Grove Road SE will be at a LOS C or better with or without project conditions. 5. The TIA addendum indicates that the stopping site distance and entering site distance from the proposed intersection of the subdivision road with Middle Road to the curve in Middle Road meet the AASHTO requirements fora 25 mph design speed. Middle Road, pusuant to the Yelm Development Guidelines standards, has a design speed of 30 MPH. This speed requires a stopping site distance of 200 and an entering site distance of 335. 6. 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 issuetl 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 traffc; 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) RCW states that a finding of wncurrency 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. 7. Middle Road is currently a substandard road, with the exception of half-road improvements located in front of the Willow Glenn Subtlivision. Frontage improvements, if based on the revised boundary lines of the original parcels will create a disconnected drive lane from Fort Stevens Elementary [o Prairie Creek Estates with partial, full improvements. 8. The series of actions by the developer, the boundary line adjustment followed by a subdivision, unless addressed through the State Environmental Policy Act, allow the development to not meet concurrency requirements for transportation improvements by avoiding the improvement of Middle Road along the smaller parcel. 9. The property is bordered on the south side by Yelm Creek, which is listed as a Shoreline of the State. There is a flood zone area adjacent to Yelm Creek, which encompasses the creek and its associated wetlands, and extends over 100 feet above the Shoreline Jurisdiction area. Section 15.32.280 prohibits construction of residential structures, or any construction that results in any increase in flood levels. 10. Chap[er14.12 YMC requires the dedication of open space for all residential development. Section 14.12.050 YMC lists four (4) attributes for qualification of open space. 11. 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. Mitigation Measures 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. Prior to final subdivision approval, the developer shall complete the following transportation improvements: a. The South half of Middle Road shall be improved to City Standards for a Neighborhood Collectorfrom the Northwest property line to the Southeast property line, including the road frontage for the lot with the existing single family residence. Additional right-of-way may be required for frontage improvements. b. The developer shall construct internal streets to City Standards for Local Access Residential. c. The developer shall provide for the continuation of streets, by connecting internal streets to the residential subdivision to the west. d. The existing single family home may retain one driveway entrance on Middle Road, with a recorded agreement between the property owner, developer, and City that the driveway entrance be relocated to the new plat internal street no later than 6 years from the date of recording. The agreement shall provide for driveway removal from Middle Road and restoration to City standards. The developer shall protect the Flood Hazard Zone area, by assuring that encroachments shall not result in any increase of flood levels. The Flood hazard zone area, and the Shoreline jurisdiction area shall be dedicated as open space. Protective fencing shall be installed at the flood zone area during all construction. Temporary erosion control systems to be approved by the City of Yelm. The developer shall enter into an agreement with Yelm Community Schools to mitigate project impacts to the School District.
