Master Plan policies concerning the provision of affordable housing for households at every income level. Noise. Exterior noise level standards are set forth in the County's Mountain House Development Title and in the Mountain House Master Plan. Both of these documents require that noise levels in primary outdoor use areas(generally back yards, also referred to as"activity areas")of new residential development not exceed an of Ldn of 60 dB unless the project design includes reasonable mitigation measures to reduce noise in outdoor activity areas to as close to an Lm,of 60 dB as possible. Where it is not possible to reduce noise in outdoor activity areas to an Ld"of 60 dB or less using practical application of the best available noise reduction measures, an exterior noise level of up to an Ld„of 65 dB may be allowed. Based on the project's design (as mitigation for noise reduction), the Community Development Department is recommending the use of the Ld"65 dB standard for primary outdoor use areas. An acoustical study prepared for the project determined that the condos fronting onto De Anza Boulevard would be exposed to an Ld"64 dB and that the condos fronting onto Central Parkway would be exposed to an Ldn 68 dB. Based on the application of the Ld"65 dB standard, noise reduction measures would be required only for the primary outdoor use areas of condos fronting onto Central Parkway. However, the applicant for the project has stated that the front yards of these condos will not be used as primary outdoor use areas. The tubular steel fencing and the omission of a gate indicate that the front yards of these units will function as entrances only and not as actual courtyards for outdoor activities. The applicant also notes that the condo CC&Rs has been revised to eliminate the possibility that such entrances could later be changed to allow enclosed courtyards. In this regard,the CC&Rs now reads as follows: "Neither the Association nor any Owner may change or modify the design, materials or appearance of Patio fences." Lastly, apart from the recreation center area and the tot lot area, there will be no outdoor activity areas for condominium units in the proposed project. Fronting of Condominiums On Central Parkway and Mountain House Creek Community Park The Master Plan requires that homes front or give the appearance of fronting onto Central Parkway and encourages the fronting of homes onto other Arterial streets. (Master Plan Policy 3.4.2 (e): "Homes shall front or give the appearance of fronting onto Central Parkway,with vehicular access provided from the rear alleys or streets. Fronting homes toward other Arterial streets, particularly Main Street and Arnaudo Boulevard, is encouraged.")The Master Plan also requires that multi-family housing along the Mountain House Creek Community Park be sited to achieve maximum exposure to the creek corridor. (Master Plan Policy 3.4.2 (h): "Multi-family housing along Mountain House Creek Community Park shall be planned to maximize exposure to the park by orienting residential units, or outdoor activity areas adjacent to the creek corridor.") As noted above under the project description, condominiums along Estes Way, De Anza Boulevard, and Central Parkway will front onto these streets. Condominiums along the Mountain House Creek Community Park will front onto this feature. ENVIRONMENTAL DISCUSSION: The project was initially considered at a program level of review as part of the Mountain House Villages E and G Project Expanded Initial Study, SCH 2003042093 ("Expanded Initial Study"). The Expanded Initial Study evaluated the development of all of Neighborhoods E and G, including an assessment of the potential environmental impacts resulting from the construction of 312 Residential, Medium-High density(R/MH)units on the site of the proposed project.The Expanded Initial Study concluded the following: • All potentially significant impacts have already been addressed in the original 1994 Final �,.
