The aim of the project is to improve riparian habitat while continuing to provide water to free-roaming horses, wildlife and livestock.
Map 1 in the preliminary decision gives you the location but doesn’t tell you the HMA.
The last page gives the legal description as T. 3 N., R. 49 E., sec. 11, SW1/4SE1/4.
That means the southwest quarter of the southeast quadrant of Section 11 in Township 3 North, Range 49 East (Mount Diablo base and meridian). Probably a 40-acre parcel.
The PLSS layer in the ArcGIS viewer puts the spring in the Stone Cabin HMA, which lies mostly within the Stone Cabin Allotment.
The Proposed Action, discussed in the CX, would install 730 feet of metal fence around the spring, two gates, up to 360 feet of buried water lines, one in-ground tank equipped with a thermoriser and one tire trough located outside the exclosure.
Comments will be accepted through September 19.
