c. Dead-end Streets
streets or greenways. Routes that are integrated into the landscape or have a planted buffer from streets are encouraged. For residential development, the front door shall face the primary street frontage with a clearly defined walkway from the street to the front door/entrance. Duplexes are exempt from this requirement. The City may allow the front door and walkways to front along a secondary street frontage, to be collocated along a driveway, or a waiver of the requirement when a walkway is not feasible from the primary street frontage due to topography, natural features, mature trees, or other factors.
Dead-end streets must be limited to no more than 600’ or up to 1,000’ if the street serves less than 50 potential lots, and must be designed for future connection unless determined by the City to be infeasible. Where a full street connection is not possible, a non-motorized connection such as a trail or sidewalk must be provided, where the City determines it is feasible.
d. Curb to Curb Width
i. Streets must be right-sized based on the anticipated built project density, anticipated traffic, and the parking program analysis required in SDC 21.02.030.E. The application of the curb-to- curb width in the Public Works Standards may be modified to meet the neighborhood design standards in ways such as requiring one parking lane instead of the standard two lanes through the deviation process outlined in the Public Works Standards in Section 6.2. ii. Curb cuts from public and private streets shall be located to allow for usable on-street parking where additional parking is necessary based on the project parking program analysis.
e. Walking and Biking Connections
A robust network of pedestrian and bicycle connections is a priority for Sammamish and shall be included in developments in a manner appropriate to the site and the surrounding connections. This may include sidewalks, paths, bike lanes, and “woonerf”-style shared
