To: All interested Agencies, Groups and Individuals

This is to give notice that the City of Clearlake has conducted an evaluation as required by Executive Order 11988 and 11990, in accordance with HUD regulations at 24 CFR 55.20 Subpart C Procedures for Making Determinations on Floodplain Management, to determine the potential affect that its activity in the floodplain and wetlands will have on the human environment for a project being proposed under Community Development Block Grant Disaster Recovery Program, Grant Number B-18-DP-06-0001. A portion of this activity is located in the 100-year floodplain and may be located within wetlands, within the northwestern portion of the City of Clearlake, Lake County, California.

This activity consists of rehabilitating about 7.78 miles of roads that experienced damage following the 2017 Sulfur Wildfire including portions of Lakeshore Drive, San Joaquin Road, Arrowhead/Park Road, Mendocino/Napa Road, Plumas Road, Joaquin Ext. Road, Monterey Road, Kern Road, Tulare Road, Mariposa Road, Lily Cove Road, Mesa/San Rafael Road, and Oak/Oakmont/Calaveras Roads. Road reconstruction would consist of grinding existing pavement sections, repaving existing roadway surfaces, removing and replacing several existing culverts, reconstructing approaches, embankment repair to existing roadway sections where erosion has undermined the existing roadway, slope stabilization and repair of the uphill slope adjoining the existing roadway where erosion caused by vegetation removal by the fire has placed hillside soils onto the existing roadway and caused additional siltation into the storm drain systems, widening some limited sections of roadways by adding an asphalt dike for safety purposes. These improvements will not result in any increased traffic capacity.

The City of Clearlake will be identifying and evaluating practical approaches to roadway design that would mitigate potential impacts within the 100-year floodplain and avoiding impacts to any wetlands. According to FEMA flood panels -06033C0677D -06033C0681D -06033C0683D -06033C0684D, approximately 3.71 acres of the project are located within the 100-year floodplain.

There are three primary purposes for this notice. First, people who may be affected by activities in floodplains and those who have an interest in the protection of the natural environment should be given an opportunity to express their concerns and provide information about these areas. Second, an adequate public notice program can be an important public educational tool. The dissemination of information about floodplains can facilitate and enhance Federal efforts to reduce the risks associated with the occupancy and modification of these special areas. Third, as a matter of fairness, when the Federal government determines it will participate in actions taking place in floodplains, it must inform those who may be put at greater or continued risk.
