Low Impact Development (LID)
In conjunction with the State's Proposition 84 Grant Program, the City of Chico implemented LID practices in City parking lots, greenways, and residential/commercial areas. The projects were designed to help prevent runoff from entering Big Chico Creek. Some of the LID projects are described below:
Site 1 and Site 4 - Parking Lot LID Retrofit and Riparian Restoration
City Municipal Parking Lot #5 was retrofitted to divert flow from the parking lot to landscape areas and onto pervious pavers as well as diverting flow from downspouts to pervious pavers. The other aspect of the project was to restore some of the riparian area of Lost Park which lies to the north of the parking lot. Bioswales, rain gardens, and native grasses and plants were installed in the riparian area to stabilize the bank and reduce erosion.
This project involved:
Site 1 - City Municipal Parking Lot No. 5
- installing 4,800 square feet of pervious surface including 360 square feet infiltration area
- 2 rain gardens
- 3 downspout disconnects
- 3 bioswales
- 3 vegetated strips

Site 2 - Neighborhood Rain Garden Program
This project involved 7 project sites (Chapman Neighborhood, Murphy Commons Apartment Complex, Crister and Madrone Neighborhood, Train Depot, City of Chico Airport, Fire Station #1, and City Hall). The project included installing:
- 1,200 square feet of pervious surface
- 10 rain gardens
- rain water tank (cistern) and pump system
- 2 street gardens
- 18 downspout disconnects
Site 3 - Crister Bioswale
This project involved one project site along Vallombrosa between Crister and Madrone Avenues. The project included installing a bioswale and 2 vegetated trenches.
Project 2A - Chapman Neighborhood
Chapman Neighborhood project involved diverting flows from the street to a rain garden, bioswale, and street garden. The rain garden and bioswale are located in a community area for the D Street and E. 16th Street neighborhood. This neighborhood participated in the development of the Chapman Neighborhood project and helps maintain the rain garden, bioswale, and street garden.
