NOTICE OF INTENT TO ADOPT A MITIGATED NEGATIVE DECLARATION 
Walnut Basin Project Date: February 18, 2026 To: State Agencies, Responsible and Trustee Agencies, Local and Public Agencies, and Interested  Organizations and Individuals Project Title: Walnut Basin Project Project Location: The project area is located along Main Street in Hesperia, in San Bernardino County, approximately  0.2 mile west from the intersection of 11th Avenue and Main Street at assessor’s parcel numbers 0408-182-14, 0408- 182-10, and 0408-182-02 (see Figure 1). The project area’s latitude and longitude are 34°25’33.64”N, 117°19’42.14”W.  The project area is located within the United State Geological Survey 7.5 Minute, Hesperia, California Quadrangle  (2015), Section 20 of Township 4 North, Range 4 West. Project Description: The City of Hesperia is proposing the construction of a new sediment and debris basin to  improve flood control and sediment management in the downtown area of the City of Hesperia (project). The  proposed sediment and debris basin would consist of a primary trapezoidal sloped inlet facility on the south end of  the basin at Walnut Street and include access roads around the basin as well as a maintenance road that extends  into the bottom of the basin to allow for basin maintenance and sediment removal. The sediment and debris basin  is designed to provide approximately 23,000 cubic yards (14.26 acre-feet) of debris storage, with erosion control  rip rap, maintenance access roads, and an outlet structure that would connect to the existing dual 10-foot-diameter  pipes. The sediment and debris basin would be designed to reduce runoff velocities and flow capacities, allowing sediment  to settle from runoff prior to entering the storm drain system. In addition, a 5-foot-high stabilized earth berm would  be designed to convey flows through the sediment and debris basin and allow for sediment deposit. The sediment  and debris basin would be 24 feet deep with a spillway to convey the flows into the existing dual storm drain pipes.  A low flow outlet would be provided to convey small storm events and to drain the sediment and debris basin.
