A. Limited Application. Dead-end streets and cul-de-sacs are limited in application and may only be permitted where, due to demonstrable physical constraints, no future connection to a larger street pattern is physically possible. See AMC 19.54.020, Block design and connectivity standards, for related standards.
B. Minimum Requirements. Streets longer than 150 feet require an approved turnaround, such as a hammerhead or cul-de-sac. The Fire Department will determine the type of turnaround required based on the number of units accessing the street and other site-specific characteristics.
C. Hammerhead Design. The hammerhead turnaround must comply with the Anacortes engineering design standards and Fire Department requirements.
D. Cul-de-Sac Design. The cul-de-sac turnaround must comply with the Anacortes engineering design standards and Fire Department requirements. Cul-de-sacs may have a landscaped center area to implement LID BMPs like bioretention. The landscaping must be maintained by the homeowner’s association or adjacent property owners.
E. Waiver of Turnaround. The requirement for a turnaround or cul-de-sac may be waived with approval of the Fire Department when the development proposal will not create an increased need for emergency operations or the impacts are otherwise mitigated. (Ord. 3040 § 2 (Att. A), 2019)
