Present Land Use
The Bolsa Chica Channel [(BCC) (CO2)], with Westminster Channel (CO4) as a principal tributary, drains to Huntington Harbour. The BCC drains the western portion of the study area, with a significant portion of property adjacent to the Seal Beach Naval Weapons Station and the Los Alamitos Armed Forces Training Base. Aside from the military facilities, this portion of the watershed is almost entirely urbanized. Agriculture is still practiced under leases granted by the Navy on portions of their property. The BCC Channel outlets into Huntington Harbour, but unlike EGGW, does not outlet into Outer Bolsa Bay. The sole ocean outlet for both Outer Bolsa Bay and Huntington Harbour is to the north at Anaheim Bay and the Seal Beach National Wildlife Refuge. Tidal influence in the lowermost portion of the BCC and East Garden Grove-Wintersburg Channels extends approximately 2 miles inland.

Document Description
Note: Scoping Notice, Review per lead The purpose of this study is to evaluate residual flood risk within a portion of the Westminster watershed. The study area includes select non-Federal drainage channels within the watershed and the receiving waters of one of the channel systems within the Bolsa Chica Ecological Reserve area. Alternatives for analysis will look at reducing flood hazards and reducing flood impacts in the vicinity of Outer Bolsa Bay, including flooding along the Pacific Coast Highway. There are two main channel systems that collect runoff from portions of urbanized areas in the cities of Anaheim, Stanton, Cypress, Buena Park, Orange, Santa Ana, Garden Grove, Westminster, Fountain Valley, Los Alamitos, Seal Beach, and Huntington Beach. The East Garden Grove-Wintersburg channel [(EGGW) (CO5)], with its principal tributary, the Ocean View Channel [(OV) (CO6)], drains into Outer Bolsa Bay which drains into Huntington Harbour. One retarding basin (Haster) exists at the upstream reach of the EGGW channel. Outer Bolsa Bay is a portion of the Bolsa Bay State Marine Conservation Area (Bolsa Bay SMCA). The East Garden Grove-Wintersburg Channel is adjacent to the Bolsa Chica Basin SMCA which includes the Bolsa Chica Lowlands and Ecological Reserve, and is a major environmental resource in southern California. The Bolsa Bay SMCA's have been designated as an area of national significance; these wetlands host a wide assemblage of resident and migratory waterfowl and marine species, including over 30 state and federally listed sensitive species.
