FINAL PUBLIC NOTICE

The Federal Emergency Management Agency (FEMA) has received a subgrant application for San Luis Obispo County Flood Control and Water Conservation District, San Luis Obispo County, CA. Pursuant to Executive Order (EO) 11988 and 44 CFR Part 9.12, final notice is hereby given of FEMA’s intent to provide funding for this project under the Public Assistance Grant Program (PA).

An initial disaster-wide Public Notice for DR-4683-CA was published 9/11/2023. Funding for the proposed project will be conditional upon compliance with all applicable federal, tribal, state and local laws, regulations, floodplain standards, permit requirements and conditions.

Under the National Environmental Policy Act (NEPA), federal actions must be reviewed and evaluated for feasible alternatives and for social, economic, historic, environmental, legal, and safety considerations. EO 11988 and EO 11990 requires FEMA to consider alternatives and provide a public notice of any proposed actions in or affecting floodplains or wetlands. This notice may also fulfill requirements under Section 106 of the National Historic Preservation Act (NHPA).

This notice serves as a project‐specific final notice for FEMA’s funding action located within a Special Flood Hazard Area. FEMA has determined the only practicable alternative is to fund repairs to the Arroyo Creek embankment. This action complies with the National Flood Insurance Program (NFIP) requirements. There is a potential for the facility to be impacted by future flooding events due to its location within the AE Zone(s) The proposed work will take place in wetlands per the United States Fish and Wildlife Service National Wetlands Inventory and will have little potential to impact or affect wetland values.

Applicant: San Luis Obispo County Flood Control and Water Conservation District

Project Title: DR4683 PW 2590 PN 711921; Arroyo Grande Creek Levee - Incomplete Work

Location of Proposed Work and Floodplain Insurance Rate Map (FIRM) Panels:

Proposed Work and Purpose: Heavy flood water caused multiple embankment washouts on the Arroyo Creek. The applicant will repair the damages back to pre-disaster function using unclassified soil and alternative method of repair. They will add cement-cement slurry in center of the levee for support. The work is not completed and is needed to avoid any future or additional loss of embankment/levee integrity. Repairing the embankment is needed to also avoid damages by flooding to the surrounding area.

Project Alternatives:

(1) (No Action) This alternative would result in risk of additional damages. If the damage is not repaired, then adverse economic and social impacts may occur and continued negative impacts may be experienced.

(2) (Repair in-kind) Repairs made in kind may result in similar damages from future flood events.

(3) (Relocation) Floodplain avoidance by relocating the facility is not a practicable alternative as the levee is functionally dependent on being in the floodplain to fulfill its purpose.

Comments: This will serve as the final public notice regarding the above‐described action funded by the FEMA Public Assistance program. Interested persons may submit comments, questions, or request a map of this specific project by writing to the Federal Emergency Management Agency, Region 9, 1111 Broadway #1200, Oakland, CA 94607, or by emailing [email protected] . Comments should be sent in writing with the subject line “DR4683 PW 2590 PN 711921; Arroyo Grande Creek Levee - Incomplete Work” at the above address within 15 days of the date of this notice.

THIS NOTICE MAY BE REMOVED FROM PUBLIC VIEW ON THE 15th DAY FROM ORIGINAL DATE OF POSTING.
