Document Description
The City of Laguna Beach Public Works Department is proposing the project, in order to restore Laguna Canyon Creek's hydrological and biological functions, and values along the 270 lineal feet of creek on City property at 20612 Laguna Canyon Road. The project is specifically intended to limit erosion and increase channel capacity. The project proposes to remove accumulated sediment within the Laguna Canyon Creek channel and install articulating concrete block (ACB) (Armorflex) lining along channel banks and other improvements. The project's proposed improvements/modification include: ACB Armorflex lining along both channel banks immediately north of the existing vehicular access bridge for reinforcement and protection; relocation of the existing pedestrian bridge to the south, immediately adjacent to the existing vehicular access bridge; an approximately 10-foot long, poured-in-place concrete transition structure to the existing reinforced concrete boxes (RCB), underneath the relocated pedestrian bridge, to convey flows from the creek widening underneath the vehicular access bridge; an approximately 4.5-foot high concrete retaining wall along the western channel bank, adjacent to the parking lot; bio-engineered slope protection (riprap with cuttings and three bendway weirs) along the toe of the eastern slope, immediately west of the Mammal Center; stream bank recontouring with understory plantings on the west slope, south of the vehicular access bridge; and remove non-native plant species and replace with native species (i.e. herbaceous plants and larger canopy tree species) throughout to address erosion and habitat loss.
