Document Description
The Department is issuing a 1602 Streambed Alteration Agreement to the project proponent who proposes to excavate up to three trenches to be used for geotechnical investigations on the site. Of these, up to two will be within the wash at this location. The Mountain Vista Specific Plan Geotechnical Investigation Trenching Project will result in excavation of these trenches on the Mountain Vista Specific Plan site, which is located in the eastern portion of the Town of Yucca Valley. The proposed Specific Plan site encompasses approximately 485 +/- acres, of which approximately 5.34 acres will be impacted by the proposed trenching. The subject trenching project is necessary to allow project engineers to conduct soil and earthquake fault testing prior to development of the Specific Plan site. There are two mapped blue line streams on the Mountain Vista Specific Plan site. Of these, only the La Contenta Wash, which occurs in the eastern portion of the site, will be impacted by the proposed trenching. Trenches No. 1 and No. 3 are within and adjacent to the streambed. Trench No. 2 occurs outside the streambed. Trench No. 3 will occur only if the findings of the geotechnical investigations conducted in Trenches No. 1 and No. 2 warrant excavation of a third trench. All impacts are temporary. Trenches will be back-filled to 90% and regarded to their pre-trenching topography. Trench No. 1 will include an area of disturbance within the streambed approximately 50 feet wide and 150 feet long. Based on this, Trench No. 1 will result in 7,500 square feet, or 0.17 acre, of temporary disturbance. Should Trench No. 3 be required, the area of disturbance will be equivalent to those of Trench No. 1. Therefore, the trenching project has potential to impact up to 0.34 acre of streambed.

Notice of Exemption

Exempt Status
Statutory Exemption
Type, Section or Code
Section 15262
Reasons for Exemption
The project involves only feasibility or planning studies for possible future actions which have not yet been approved. Proposed trenching is necessary for the engineer to conduct soils testing and fault investigation upon which preparation of EIR for the Mountain Vista Specific Plan is dependent.
