Chapter 3 Comments and Coordination
The proposed barriers would be constructed along the shoulder of the highway. Proposed
Soundwall #101 would partially obstruct the view of the Cliff House Inn from the U.S.
101. Therefore, the views of the affected property owners (i.e. the owners of impacted
residences represented by Site #A1 and commercial property owner) must be considered
before making a final noise abatement decision. Community members have expressed
the desire for SW101; however, every effort would be made to improve visibility of the
Cliff House Inn from the U.S.101.

The Department’s Noise Study Report 12/24/07 Table 4
In La Conchita, a minimum of two 12-foot tall soundwalls built along the edge of the
shoulder were determined to provide at least a 5 dBA reduction in noise for the areas
represented by B-B4 (44 residences in La Conchita) (see Table 2.2-11 or Appendix F).
These proposed soundwalls would block the residents’ view of the Pacific Ocean.
Community members have expressed they would not want the soundwall constructed.

The Department’s Noise Study Report 12/24/07 Table 4
In Carpinteria, a minimum of four 12-foot tall soundwalls (two along the edge of
shoulder and two along state right-of-way) have been proposed to provide at least a 5
dBA reduction in noise for the areas represented by D to D6 (see Table 2.2-12 or
Appendix F). Community members along Via Real have expressed their opinion that the
