The following environmental mitigation measures were incorporated into the Conditions of Approval for this project in order to mitigate
identified environmental impacts to a level of insignificance. A completed and signed checklist for each mitigation measure indicates that
this mitigation measure has been complied with and implemented, and fulfills the City's monitoring requirements with respect to Assembly
Bill 3180 (Public Resources Code Section 21081 .6).
Mitigation Measure
1. Mitigation required to achieve the required 60 dBA CNEL
exterior noise standard includes a 5.5 foot high solid
noise wall located along La Costa Avenue. The wall
shall be located at the top of slope. The wall may be
constructed stud, stucco, 3/8-inch plate glass, any
masonry material or a combination of these materials.
The wall must have a surface density of at least 3.5
pounds per square foot and shall have no openings and
Qaps.
2. Mitigation required to achieve 60 dBA CNEL exterior
noise standard for the third floor balconies for units
located along La Costa Avenue includes a solid five-foot
high noise barrier (relative to the balcony floor). The
barrier must have a surface density of at least 3.5
pounds per square foot and shall have no openings and
gaps. The barrier may be constructed of stud, stucco,
3/8-inch plate glass, any masonry material or
combination of these materials.

Mitigation Measure
3. Mechanical ventilation shall be provided for the units
facing La Costa Avenue as specified in the acoustical
analysis prepared for this project by Mester Greve
Associates on May 3, 2002, to achieve 45 dBA CNEL
interior noise level. Prior to issuance of a building
permit, the developer shall submit a supplemental
acoustical analysis from the acoustical consultant stating
that the architectural plans have been designed in
compliance with the recommendations stated in the
acoustical report.
4. The applicant shall pay habitat in-lieu mitigation fees
consistent with the Habitat Management Plan (HMP) and
the Biological Confirmation Analysis (dated September
7, 2006) as follows, Group D: 1.12 acres of unoccupied
coastal sage scrub/mixed chaparral; GroupE: 2.5 acres
of annual (non-native) grassland; and Group F: 2.07
acres of disturbed lands.
