22.42.050 New street design.
A. Purpose. The purpose of this section is to establish appropriate design principles for the layout and configuration of new streets. These guidelines are applicable to all new developments that include the development of new streets, public or private, and are constructed to serve new development.
B. General Goals. New streets shall be designed in accordance with the City of Monroe Public Works Design and Construction Manual, the DOE Stormwater Manual for Western Washington, the Low Impact Development Technical Guidance Manual for Puget Sound, and the WSDOT/APWA Standard Specifications. If inconsistencies occur the City of Monroe Public Works Design and Construction Manual shall have precedence.
C. In addition to technical engineering requirements, the design of new streets should strive to preserve public safety by encouraging a safe, attractive walking environment and incorporating traffic calming techniques into their design.
1. Developments shall provide a safe and convenient network of vehicular and pedestrian/bicycle circulation that connects to the surrounding road/access network, pedestrian/bicycle facilities and adjacent parcels.
2. New development is encouraged to provide pedestrian connections to facilitate access to existing and planned trail systems.
D. The following are required of all new development:
1. Gated Community. Gated communities are prohibited to maintain an integrated street network.
2. Fire Apparatus Access Roads. A public street or fire apparatus access road is required within one hundred fifty feet of all portions of first floor exterior walls of new buildings.
a. Minimum Width. The minimum width of fire apparatus access roads shall be twenty feet.
b. Structural Number. The pavement section shall be designed to provide a Structural Number of 2.67.
c. Exception. Where a required fire apparatus access road cannot be installed due to topography, waterways, nonnegotiable grades, or other similar conditions the building official, after consultation with the fire department, may increase the dimension if an approved alternative means of fire protection is provided.
3. Street Ends. All dead end roads, driveways, and access ways more than one hundred fifty feet in length shall be provided with a turnaround in accordance with the City of Monroe Public Works Design and Construction Manual.
4. Underground Utilities. All new utilities are to be installed underground in new developments.
5. Roadway Geometrics. All new streets shall meet all applicable requirements below in Table 22.42.050(D)(5): Roadway Geometrics, and in this section.
