State Parks Project – Creek Channel Stabilization at Pearrygin Lake State Park

A. The project proposes stabilization of the existing channel of Pearrygin Creek with a large woody material live crib structure and excavation of a channel and bench. Excavated material will be used as backfill for the live crib structure and for construction of a planted stockpile area. Areas within the grading limits and staging/access areas will be planted with riparian and shrub-steppe plantings. Irrigation will be provided for the new plantings. B. Work will include the following: 1. Construction of staging areas and implementation of temporary erosion and sediment control best management practices 2. Excavation, construction, and backfill of new live crib 3. Excavation of new channel and bench and placement of streambed cobble in channel 4. Placement of excavated material to construct planted stockpile area 5. Installation of riparian and shrub-steppe planting and hydroseed within grading limits and staging/access areas 6.
