STRUCTURES AND UTILITIES

This section addresses structures and utilities that could be affected by implementation of the proposed
action. The season of construction has no bearing on the impact analysis.

4.10.1 Significance Criteria
Impacts to structures and utilities would be significant if they would (1) result in the need for new systems
or (2) result in substantial alterations to existing systems. Because an increase in service demand would
not occur with the proposed action, this analysis focuses on displacement or disruption of structures and
utilities.
4.10.2 Alternative 1
Impacts of Alternative 1a
Receiver Sites
South Oceanside
A buried sanitary sewer ocean outfall pipe located just north of Loma Alta Creek would not be impacted
by Alternative 1. The pipe would not be displaced and interruption in service would not occur because
the pipe is located beneaththe surface. The proposed beach fill would be beneficial for this outfall structure
because the sand would serve as additional cover to protect the pipeline. The existing outlets for the storm
drains at the end of Marron Street, Tyson Street, and the pipe at Forster Street would be below the
proposed sand fill. As described in Section 2.4, sand placement around storm drain outlets would be dug
out to allow proper drainage. Accordingly, impacts would be less than significant.
The bottom of the public stairs at the end of Tyson Street, Ash Street, Marron Street, Cassidy Street, and
Vista Way may be covered by the fill, which would tend to stabilize the stairways. As public access to the
beach via these stairways would not be affected, significant impacts would not occur upon implementation
of Alternative 1. The public access ramps at Wisconsin Street, Forster Street, and just north of Loma Alta
Creek would not be affected. The access road at Oceanside Boulevard would also not be impacted
because sand placement would cover only the lower end of the road. A private stairway with access to
