B land uses within the project limits under consideration include residential properties. It
was predicted that the future carpool lane project along U.S. 101 would impact many of
the residential areas adjacent to the freeway within the project limits. Proposed soundwall
locations are shown in Appendix F.
Residential Areas
All impacted residential areas have been considered for noise abatement. They are
represented by Sites #A1 thru #A5 in Mussel Shoals, Sites #B thru #B4 in La Conchita,
and Sites #D, D1, D2, D5, and D6 in the City of Carpinteria.
Hotels/Motels
The Cliffhouse Inn located in Mussel Shoals is represented by field reading Site #A1.
Parks
There is one park/recreational area located at Bailard Avenue within the project limits.
No traffic noise impacts at the future predicted noise level of 66 dBA-Leq (h) or above
has been predicted at this park. Based on predicted noise levels, freeway traffic noise
impact has not been predicted to occur at the park located on the southwest corner of U.S.
101 and Bailard Avenue.
Commercial Developments
There are no commercial developments with exterior frequent human use.
Undeveloped Lands
There are two undeveloped land parcels that will be developed in the future. At 6380 Via
Real, 37 single-family units have been proposed for construction. At the “Bluffs 3”, King
Resorts with 213 hotel rooms has been proposed for construction.
The residential areas of Mussel Shoals, La Conchita, and the City of Carpinteria qualified
for noise abatement consideration as part of a Type I project. Therefore, various heights
of acoustically feasible soundwalls have been provided as noise abatement measure for
both BUILD alternatives. Proposed soundwalls SW 101 and SW 102 in Mussel Shoals
benefit approximately 43 residences; SW 103 and SW 104 in La Conchita benefit 44
residences. In the City of Carpinteria, proposed soundwalls SW 105, SW 106, SW 107,
SW 108 provide noise reduction to 31 and 18 residences.
Proposed Acoustically Feasible Soundwalls For BUILD Alternatives:
In the community of Mussel Shoals, a minimum of two 10-foot tall soundwalls were
determined to provide at least a 5 dBA noise reduction for the areas represented by sites
A-1 through A-5 (43 residences in Mussel Shoals) (see Table 2.2-10 and Appendix F).
