STREET DEVELOPMENT STANDARDS
The City of Des Moines has adopted these Street Development Standards to set forth specific, consistent, and acceptable street design and construction elements for developers and other private parties constructing or modifying street or right of way facilities which require City licenses or permits, and to establish uniform criteria to guide the City’s own design and construction of new City streets or reconstruction of existing streets.
In addition, these Street Development Standards are intended to support City goals for achieving affordable housing, providing adequate facilities for development in an efficient manner, complying with storm water management and environmental policies, and to balance these goals with the general safety and mobility needs of the traveling public.
These Standards establish uniform technical requirements for street design, construction, and reconstruction within the City of Des Moines. In establishing these uniform technical requirements, the Public Works Director has sought to encourage standardization of street design elements where necessary for consistency and to ensure so far as practical that motoring, bicycling, and pedestrian public safety needs are met. Considerations include safety, convenience, aesthetics, proper drainage, economical maintenance, and protection of environmental resources.
