Depot Park First Street West Frontage Improvement Project

Project Location: First Street West Frontage of Depot Park

Project Purpose: Reduce the risk of flooding for homes and businesses along First Street West and improve safety for people traveling along First Street West during storms, while retaining an open drainage channel along Depot Park.

Flooding on First Street East at Depot ParkProject Description: First Street West is subject to flooding during even relatively minor storms.  A significant source of flooding is the small open drainage channel adjacent to Depot Park.  Runoff from the watershed above the Mountain Cemetery is conveyed in a 54” diameter pipe culvert under the eastern edge of First Street West, next to Arnold Field.  This pipe drains under the Depot Park driveway to the drainage channel along the Depot Park frontage.  Roots from four large eucalyptus trees severely restrict the capacity of this drainage channel.

During winter storms in 2019, a metal pipe at the downstream end of this drainage channel collapsed, resulting in a sinkhole in a pedestrian pathway over the drainage channel.  Temporary repairs kept drainage flowing through the rest of the rainy season.  The pathway supported by this culvert has been removed.

The project includes removal of stumps and roots from four eucalyptus trees, enlargement of the drainage channel to reduce flooding, and stabilization of channel banks along the Depot Park frontage.  Trees will be planted between the Depot Park picnic area and the drainage channel.  Vegetation will be planted along the channel.  The existing pathway in Depot Park will be reconstructed to end at the picnic area. The boardwalk south of the bike path will be retained.

Project Budget: TBD

Project Status: The upper portions of the Eucalyptus Trees were removed in winter 2020. The City has put the channel improvements construction out-to-bid. The channel improvements are expected to be completed in Fall 2020. Tree planting and channel revegetation are also expected to be completed in Fall 2020.
