FINDING OF NO SIGNIFICANT IMPACT
Yountville Mobile Home Park Flood Barrier Project 
FEMA-DR-1044-CA, HMGP #1044-005


The Town of Yountville, California has applied, through the California Governor's Office of Emergency 
Services (OES) to the Federal Emergency Management Agency (FEMA), for assistance with the 
construction of a flood barrier wall to protect two mobile home parks from periodic flooding.  FEMA is 
proposing to provide assistance for this project through the Hazard Mitigation Grant Program (HMGP) 
under Presidential Disaster Declaration FEMA-DR-1044-CA.  This Environmental Assessment (EA) has 
been prepared according to the requirements of the National Environmental Policy Act of 1969 (NEPA), 
the Council on Environmental Quality's regulations for implementing NEPA (Title 40 of the Code of 
Federal Regulations [CFR] Parts 1500-1508), and FEMA's implementing regulations (44 CFR Part 10).

The Yountville Mobile Home Park Flood Barrier Project (Project) would surround the Rancho de Napa 
and Gateway Mobil Home Parks in the southeast corner of the town of Yountville, California. The mobile 
home parks are located within the 100-year flood plain of the Napa River.   There are three primary parts 
to the Proposed Action: (1) construction of a masonry floodwall around most of the mobile home parks 
that closely matches the alignment of the existing perimeter fence, (2) construction of closure structures at 
the park's two entrances to provide flood protection at these locations, and (3) installation of interior 
storm drainage facilities consisting of storm drain lines, a drainage collection basin, and a pump station to 
handle storm water that falls within the parks.

Based upon the conditions and information contained in the Final Environmental Assessment for the 
Yountville Mobile Home Park Flood Barrier Project (April 2003) and in accordance with FEMA's 
regulations in 44 CFR Part 10 (Environmental Considerations) and Executive Orders 11988 (Floodplain 
Management), 11990 (Protection of Wetlands), and 12898 (Environmental Justice), the following is 
concluded:

A Finding of No Significant Impact.  Therefore, an Environmental Impact Statement will not be prepared 
based on the fact that there will be no long-term adverse impacts on the natural environment resulting 
from this project.

This Finding of No Significant Impact is based upon the conditions contained in the Final Environmental 
Assessment.
