MND - Mitigated Negative Declaration
Present Land Use
The City of Highland (City), in coordination with East Highlands Ranch - Master Homeowners Association (EHR-MHOA), is proposing to: replace the underground Line A storm drain facilities situated between the EHR clubhouse and the nearby Bledsoe Gulch, to which Line A outlets; replace the storm drain outfall facilities in Bledsoe Gulch; regrade Bledsoe Gulch sideslopes in the vicinity of the Line A new outfall which is severely eroded and threatening homes; construct new maintenance access road over the reconstructed stormdrain. The approximately 300 feet of the existing 48-inch RCP will be replaced with new 48-inch RCP within the same alignment but at approximately 10 feet deeper than the existing line to promote positive flow given the severely eroded creek head, base, and sideslopes and to reduce creek erosion. The total work area is approximately 0.48 acre.
Specifically, the Project will occur approximately 200 feet south of the East Highlands Ranch Community Center building within the orange grove and within and around the upstream terminus of Bledsoe Gulch, 6892 Cloverhill Drive, Highland, CA
