Mount Diablo Creek Watershed Planning Group

Mission Statement

We are an inclusive planning group of people who care about the watershed and are working to develop a plan that identifies voluntary ways to steward the watershed.

 


1. Recommendations on Watershed Education

Goal: Increase watershed awareness, stewardship and responsibility.

Objectives

1. Develop materials that communicate an understanding of the Mount Diablo Creek Watershed ecosystem.

2. Organize local events to promote watershed awareness and restore habitat.

3. Encourage place-based learning and service projects through the use of existing partnership between local schools, community organizations and public agencies.

4. Avoid promoting a political agenda and produce fact-based, balanced materials.

 

Actions

Lead Organization, Agency or Individual

1.1. Work with local representatives and a designer to develop an interpretive watershed map showing natural features, infrastructure, and public features (e.g., parks, schools, etc.). The map may be based on an aerial photo and/or a topographical map.

CCRCD

1.2. Adapt the Caring for Our Creeks guide to the Mount Diablo Creek Watershed. Include contact information for local groups and agencies. Cite references and strive to minimize bias.

CCRCD

1.3. Develop a Mount Diablo Creek Watershed website with links to and from websites of local groups and agencies. Ensure accuracy and cite sources. Find a sustainable host.

1.4. Create outreach materials for the general public that could include a presentation, brochure, display or poster that could be in presented in person or distributed via a website, cable access, or DVD. Explore developing multilingual versions. Develop materials for different age groups that reflect different ways of learning.

[1] “Watershed approach” refers to looking at the whole system rather than a single property and, among other things, looking at the issue of impervious surfaces in upland areas as well as flow in the creek channel.

 

[2] Channelization is the creation of an earthen or concrete channel with no vegetation. This approach to flood management, which was popular in the 1950s and 1960s, removes the habitat value of the creek and creekside area and moves water faster. It can result in more flooding downstream and often has significant maintenance costs associated with it because the channel tends to fill in with sediment. 

[3] Scenario modeling would use engineering standards to estimate impacts of impervious surfaces.

[4] Keeping the creek and floodplain as public property would avoid the kinds of damage to private property (e.g., flood damage, damage caused by bank collapse) that can occur when structures are built too close to the banks of a creek or in the floodplain.

 

[5] “Sensitive species” refers to threatened, endangered and species of concern at the state or national level.
