Folder Plunge Creek


Plunge Creek is a wonderful integrated habitat and water conservation project proposed for funding from the Integrated Regional Water Management, coordinated by the Santa Ana Watershed Project Authority, and lead by the San Bernardino Valley Water Conservation District. The goal of the project is to restore the Plunge Creek System back to a braided stream using natural processes and hydrology, thereby removing invasive grasses and increasing habitat for the endangered San Bernardino Kangaroo Rat and other rare and endangered species, as well as allowing the water to spread out and infiltrate into the ground which will recharge the basin. The project goals work well with the broader goals of the Santa Ana Watershed One Water One Watershed program; it includes the recharge of native surface water, the enhancement of groundwater quality, improvement of endangered species habitat, works in a collaborative setting, and achieves cost effectiveness by working on SBVWCD owned lands. 



Plunge Creek has progressed fairly since it was proposed. Having hired ICF International and Northwestern Hydraulic Consultants to help work on the project, the 30% design was completed and the project was adjusted based on the design. Flood Control and the Fish and Wildlife Services were contacted and liked the idea of the project. Plans for metering the system are in progress. Also, instead of having a very inclusive design, an engineer was based on site in order to adjust for unpredictable occurrences. The full design for the project should be done by July 2016.


Here is some background on the project with more information to come as we get notice to proceed.
