![]() Considerations include safety, convenience, pleasant appearance, proper drainage, and economical maintenance. In adopting these road standards, the City has sought to encourage standardization of road design elements where necessary for consistency and to assure so far as possible that motoring, bicycling, equestrian, and pedestrian public safety needs are met. In addition, these standards are intended to support the City’s goals for achieving affordable housing, providing adequate facilities for development in an efficient manner, complying with stormwater management and sensitive area policies and to balance these goals with the general safety and mobility needs of the traveling public. The City of Maple Valley has adopted these road design criteria primarily to set forth specific, consistent road design elements for developers and other private parties constructing or modifying road or right-of-way facilities which require City licenses or permits.
