Policies <br />Roadway Design <br />1. Design roadway facilities constructed in conjunction with development projects according to the intended <br />function. <br />2. Upgrade existing roadways, when warranted, by demonstrated volume, safety or functional needs, <br />taking into consideration environmental limitations. <br />3. Emphasize improvements to management, maintenance, and utilization of the existing street and <br />highway system. <br />4. Design/enhance residential street systems to discourage through traffic and to be compatible with biking <br />and walking. This includes consideration of traffic calming measures on local streets and, in some <br />cases, collector streets. <br />5. Design/enhance collector and arterial roadway corridors to minimize through traffic on local streets in the <br />functional classification system, and to be compatible with other transportation modes including transit, <br />bicycle, and pedestrian. <br />6. Use adequate transitions and buffers including, but not limited to, earth berms, walls, landscaping, and <br />distance to mitigate the undesirable impact of high volume roadways. <br />7. Promote use of sound mitigating features for residential development adjacent to high volume roadways, <br />and make property owners and land developers responsible for noise attenuation at new developments <br />near high volume roadways. <br />1-1UG0 2040 COMPREHENSIVE PLAN UPDATE <br />DRAFT Dec14-17 <br />for review only <br />8. Encourage beautification of local corridors, where appropriate, with amenities such as landscaping, <br />decorative street lighting, and monuments. <br />Roadway Function and Access <br />1. Provide logical street networks to connect residential areas to the regional highway system and local <br />activity centers. <br />2. Adequately control access points to the regional roadway system (including minor arterials) in terms of <br />driveway openings and side street intersections. <br />3. Provide access to the local street system (including collector and local streets) in a manner that <br />balances the need to safely and efficiently operate the street system with the need for access to land. <br />4. Encourage, through roadway design and signage, intra -area trips on minor arterials rather than the <br />principal arterial system, and promote serving regional trips on the metropolitan highway system. <br />5. Separate, to the extent possible, conflicting uses on the public street system in order to minimize safety <br />problems. Give special attention to pedestrian and bicycle routes. <br />6. Provide access to developing sites using current functional classification and standards. <br />7. Review and update regional and local functional street classification and coordinate with adjacent cities <br />and Washington County. Establish subcategory classifications and criteria for local streets if warranted. <br />Revise local roadway classifications when warranted. <br />DRAFT Dec14-17 <br />for review only <br />TRANSPORTATION 201 <br />
