Marian Meadows Rezone and Subdivision Final Environmental Impact Statement 3-76 portion of the site is likely to be much higher than the lower portion. The relative difficulty of snow removal may result in longer road closures in that area due to delays in clearing roads. The difference in the amount and cost of snow removal within the development may be addressed by higher charges for higher elevation areas. 19 Would there be changes to how local roads fit into the character of the local community? As described above, roadways in the study area currently provide several functions, including general mobility, freight transportation, direct property access, play areas for children, and recreational facilities (e.g., ATV and snowmobile routes). The character of shared use roadways would change over time. Without or with the project, roadways would likely be used more by motor vehicles compared to other uses and the build scenarios would further increase motor vehicle usage. Although the proportionate share of motor vehicles using the roadways would increase, the functional classifications and general character of shared use roadways are not expected to change. General mobility, freight transportation, direct property access, and recreational usage would be maintained. Roadways could still serve as extensions of front yard and play areas; however, the increase in traffic volumes may tend to lead to less use. Within the existing Easton Village subdivision, volumes on Country Road are projected to increase more than four-fold with 10 percent of project trips presumed to take that route. If more project trips chose that route, the increase would be greater. The total number of trips is relatively low, but it may be great enough to change perceptions of safety for children playing in the area. 20 What mitigation is needed for the alternatives? Level of Service mitigation From the traffic operations perspective, all of the study intersections under Alternative 1, Tenure Scenario 1with 443 units and full-time residents operate acceptably above the LOS C standard. Therefore, no mitigation is needed with respect to traffic operations. The potential need for left-turn lanes were examined along Sparks Road at Pit Way, Country Drive, and the project access point (West Sparks Access) where the left turns are highest. WSDOT provides guidance (not standards, regulations, or criteria) on when a left-turn lane should be constructed in the WSDOT Design Manual, Exhibit 1310-12a. In this exhibit, the need for a turn lane is based on the volume of left-turns compared to the total through-movement volume of the roadway and the posted
