Manzanita Greening and Canyon Health Project
Applicant: San Diego Canyonlands

The applicant proposes to stabilize and restore Manzanita Canyon, where streambed degradation, erosion, and invasive species are causing channel widening, scour, and creek incision which threaten streambank failure and damage to City of San Diego (City) sewer infrastructure. The Project will re-establish natural creek functions by installing streambed and bioengineered streambank stabilization features to prevent erosion and sediment loss. A box culvert and headwall will be installed at the upstream end of the project near Thorn Street to protect from erosion and creek incision. The project will also establish a small area of stream channel.
