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, 2003, prepared by SCA Consulting Group) Traffic Impact Analysis (dated September 2003, and updated November 2003, prepared by Transportation Engineering NorthWest) Preliminary Storm Drainage and Erosion Control Report (dated October 2003, prepared by SCA Consulting Group) 2. The traffic impact analysis (TIA) submitted as part of the subdivision application indicates that the project will generate 928 vehicle trips per day, with a PM peak of 98 vehicles per hour. The TIA, assuming a baseline annual growth rate of 4%, indicated that: The intersection of 105th Ave, and Clark Road will be at a Level of Service (LOS) A, with an average delay of 9 seconds. The signalized intersection of Clark Road and Yelm Avenue will be at a LOS A, with an average delay of 9 seconds. The intersection of 3rd Street and Yelm Avenue will be at LOS C, with an average delay of 22 seconds. The intersection of Mosman and 1st Street (507) will be at LOS D, with an average delay of 33 seconds. The signalized intersection of Yelm Avenue and First Street will be at LOS D, with an average delay of 48 seconds. The intersection of Yelm Avenue West (510) and SW Longmire Street will be at LOS F, with an average delay of 56 seconds. The intersection of Yelm Avenue (507) and NE 103rd Street will be at LOS D, with an average delay of 34 seconds. The intersection of Yelm Avenue East (507) and Bald Hills Road will be at LOS C, with an average delay of 30 seconds. Frontage improvements will be constructed along 105th Avenue SE. The subdivision will provide for a road connection to the existing neighborhood to the north, with a narrowed street, traffic signs, no parking and a raised pedestrian crossing. The subdivision will provide connecting sidewalks from Yelm Terra to the sidewalks in the Prairie View subdivision. 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) RCW 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 the Mosman Street/SR 507 intersection including intersection realignment, is listed as a project on the 2003 - 2008 Transportation Improvement Program. There is no financial commitment currently in place to complete the improvement. Improvements to Mosman Street to 2nd Street including widening the roadway, is listed as a project on the 2003 - 2008 Transportation Improvement Program. There is no financial commitment currently in place to complete the improvement. Improvements to Mill Road including road realignment, is listed as a project on the 2003 - 2008 Transportation Improvement Program. There is no financial commitment currently in place to complete the improvement. Private streets within the City limits shall not be allowed except when approved by the City and when all conditions of Section 4B.070, Development Guidelines are met. Section 4B.070(B) states that private streets are not allowed when the street is connected to two public streets. Section 4B.150 Yelm Development guidelines states that sight distance at intersections shall be in conformance with the WSDOT Design Manual and the AASHTO Green Book. The City’s Comprehensive Transportation Plans connectivity policy recognizes that increasing connections throughout the City not only reduces traffic congestion, but also increases the sense of unity of the community. Section16.16.090 Yelm Municipal Code (YMC) states that the layout of streets shall provide for continuation of streets existing in adjoining subdivisions. 5. Mosman Street from 3rd to SR 507, and 3rd Street from the Praire View subdivision to SR 507 are currently substandard in that they have travel lanes less than 12 feet in width in areas. 3rd Street in the Prarie View subdivsion does not meet current standards for a neighborhood collector street. There is a berm at the intersection of Clark Road and 105th Avenue which may limit sight distance below acceptable standards with the addition of traffic to 105th Avenue. 6. The public right-of-way at 105th Avenue ends at the western property line of the development and 105th continues as a one lane, curved, right-of-use road to Mill Road and SR 507. This right-of-use road does not meet any public street standards, is a one-way street used for two way traffic, and contains no pull-outs. The development will provide alternate connectivity in the form of a public street from 105th, through Yelm Terra and Prairie View, along Mosman to SR 507. 7. Section 14.16.110 YMC provides for the preservation of trees on private property with new development and requires that existing trees not be removed until a final decision is made regarding the feasibility of preserving existing trees. The existing trees on this property are a group of large Douglas Fir. The trees located in the area of proposed stormwater treatment areas are in danger of future tree failure with grading near the base of the trees. Existing trees that are located in areas of qualified open space should be protected during development with protective fencing at the drip line. All machinery shall be kept out of the drip line.  8. Chapter14.12 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. Section 14.12.060 allows for a fee in lieu of open space under certain conditions. 9. 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 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. Credit should be given for the existing single-family dwelling. 2. Prior to final subdivision approval, the developer shall complete the following transportation improvements: The north half of 105th Avenue shall be improved to City Standards for a Neighborhood Collector from Clark Road, to the western most property line of the proposed subdivision. The right-of-use portion of 105th Avenue shall be blocked by a barricade meeting Yelm Development Guidelines and Manual of Uniform Trafffic Control Devices (MUTCD) standards at Mill Road and signed pursuant to MUTCD as a private road with no though access. The developer shall ensure sight distance at the intersection of Clark Road and 105th Avenue meets Yelm Development Guidelines and ASHTO specifications. 3rd Street, between the proposed subdivision and Mosman Street, shall be improved to a 24 foot asphalt driving surface with vertical concrete curb on both sides, and signage for no parking. 3rd Street, from Mosman to Yelm Avenue East (507) and Mosman from 3rd Street to First Street (507) shall be improved to a 24 feet driving surface with 2-foot shoulders. Sidewalks from the proposed development must connect to the sidewalks in the Parkview development, pursuant to the TIA. 3. Prior to any land clearing, a site plan including the location of all trees to be retained and removed (exceeding 8 inches in diameter) must be reviewed and approved by the Community Development Department. Tree losses shall be mitigated by planting at least a 2 to 1 mix of evergreen (70%) and deciduous trees (30%), with a minimum of a 2-inch caliper measured at 4 feet from the ground, around the perimeter of the storm pond areas, and in the qualified open space areas. Trees to remain must be protected during construction pursuant to Chapter 14.16 YMC. 4. Pay open space “Fee in Lieu of” for the difference between the qualified (usable) open space, and the required open space. 5. The developer shall enter into an agreement with Yelm Community Schools to mitigate project impacts to the School District.
