Document Description
The Armstrong Ranch Specific Plan will establish land use, development and design standards for 199 acres to allow up to 994 single-family detached and attached residential units at a density of 5 dwelling units per acre within six Planning Areas (PA's). The residential units include both conventional single family detached units on individual lots and "Z" lot homes with residential units on individual lots. In addition, single family attached townhomes and condominium residential units are proposed. Lot sizes will range from 2,700 sf to 7,125 sf. Residential units can be transferred among the planning areas as long as the total number of residential units of the Specific Plan does not exceed 994 units. An elementary school site is proposed in the southeast corner of the site on approximately 10 acres within the Mountain View School District and will serve the elementary students (K-5) that live east of Carpenter Avenue. If the elementary school site is not developed, the land will revert to the underlying low density residential use.
