Mountain House Specific Plan III ........................................................................................................................................................................... 9.6.2 Specific Plan ill Description The internal vehicle circulation system of Specific Plan III consists of collector streets, local streets, alleys and emergency vehicle access(EVA)crossings of the pedestrian open space corridor. The collector streets provide the major access to the residential areas from the arterial streets. Local streets and alleys distribute the traffic throughout the residential areas. Office,commercial and industrial park areas are generally located off arterial streets, and receive access directly from arterial streets or, occasionally,collector streets and internal driveways and alleys. All schools are served by collector _ streets which border at least three sides of the school. Local streets and pedestrian paths provide access to the other sides of the school properties. Street pavement widths are generally minimized with an emphasis on short,quiet streets that discourage through traffic consistent with safety considerations. Shorter and narrower streets also reduce development and maintenance costs,discourage speeding, enhance pedestrian bike safety, and improve the visual appearance and scale of street corridors. Parking is allowed on all collector and local streets. — Alleys serving smaller lot residential areas are planned for several areas within Specific Plan III, _ especially across from school entries to reduce traffic conflicts from vehicles entering the stream of traffic from driveways. Emergency Vehicle Access easements are planned at two locations crossing the north/south pedestrian corridor running between the community park and neighborhood center of Neighborhood A/B to ensure quick response times and flexibility for emergency service access. These EVA easements shall not be improved to extensions of local or collector streets without an amendment to this Specific Plan after — public hearings are held in Neighborhood AB. 9.6.3 Implementation Measures a. Street pavement widths shall be minimized,consistent with safety considerations to reduce _ development and maintenance costs, discourage speeding, enhance pedestrian and bike safety, and improve the visual appearance and scale of street corridors. b. Access standards shall define appropriate level of access to and from each type of street in the functional classification system. Unsignalized"right tum in,right turn out'intersections(excluding those described for traffic signals, above)may be permitted on arterials, if consistent with safety criteria such as sight distance and minimum spacing. Landscaped medians shall be constructed along high volume arterials, and driveway access and on-street parking shall be prohibited(see the MHCSD — Design Manual for landscape treatments). 9-14 Draft 03/14/05 ...........................................................................................................................................................................
