If Trimark can show that it is not possible to reduce noise in outdoor activity areas to an Ldn of 60 dB along Mascot Boulevard and De Anza Boulevard, the Review Authority (i.e., the Planning Commission) could allow an exterior noise level of 65 dB Ldn. An exterior noise level of 65 dB Ldn along these streets could be accomplished by constructing sound walls that are 6 to 7 feet in height. Such sound walls would provide fencing for the rear yards of residential lots in Neighborhood "F." Sound walls of this height at this location would be consistent with Section 9- 1022.2 (c)(2), which allows fencing up to 7 feet in height in the rear or non-street side yard. Comment. Trimark would need to prove that a redesign of the subdivision, or the use of other mitigation measures consistent with the Master Plan, Specific Plan I, Public Financing Plan, and the Development Title, to reduce noise impacts to acceptable levels is not feasible. The Mountain House Neighborhood"F"Project Initial Study and Mitigated Negative Declaration,SCH#90020776 indicates, however, that if homes are set back farther from De Anza Boulevard and Mascot Boulevard and lot sizes are reduced, the desired noise levels in outdoor activity areas could be achieved. (Note: If lot sizes are not reduced but setbacks are increased, the Mountain House Neighborhood "F"Project Initial Study and Mitigated Negative Declaration,SCH#90020776 states that the desired noise levels could be achieved but at the expense of the"project's goals for affordable housing, non-auto related transportation and associated benefits regarding air quality and noise.") If Trimark does not prove to the satisfaction of the Review Authority that it is not possible to reduce noise in outdoor activitity areas to a Ldn of 60dB, one of the following actions would need to be taken: • Trimark would need to redesign the subdivision, or utilize other mitigation measures, to reduce exterior noise along Mascot Boulevard and De Anza Boulevard to acceptable levels, consistent with the Master Plan, Specific Plan I, Public Financing Plan, and the Development Title; or • Trimark would need to request a Mountain House Development Title Text Amendment to allow the construction of sound walls over 7 feet in height under certain conditions. Depth:Wldth Ratio. Table 9-310.3 of the Development Title requires lots in residential zones not to exceed a 3:1 Depth to Width Ratio. All residential lots in the proposed project comply with this requirement, except for the following lots: Lot# Depth Width Ratio 466 198' (avg.) 65' 3.05:1 467 200' (avg.) 65' 3.08:1 468 200' (avg.) 65' 3.08:1 A condition of approval is recommended to reconfigure these lots to bring them into conformance with the 3:1 ratio requirement. PLEP Consistency. Although technically a part of the Development Title consistency analysis,the proposed project's consistencywith the Public Land Equity Program(PLEP)is reviewed separately here. Findings: 1. The amount and location of public lands on the subject parcel are consistent with the Mountain House Master Plan and Specific Plan I. -23-
