Stormwater Management Program
Reduce Stormwater Pollution From: Roads and Highways, Forest Roads, Public and Private Parcels
This project near Thunderbird lodge on Lake Tahoe's east shore proposes to restore a portion of Marlette Creek to improve stream function, water quality, and fish habitat and provide erosion control and stormwater treatment at directly connected outfalls from SR 28.
Specifically (1) Capture and treat State Route 28 stormwater runoff prior to entering Marlette Creek by installing treatment at each stormwater outfall.(2) Repair incision and stabilize the bed of S. Fork of Marlette Creek and provide fish passage. (3) Provide fish passage at the SR 28 culvert. (4) Stabilize SR 28 shoulders, road embankments, and dirt parking areas that are directly connected (5) alleviate ponding on SR28.
Targeted Performance Measures
