Major Grant Touted to Transform Twain Harte

T-Stan IRWMA News

Twain Harte, CA – A new grant will help Twain Harte turn stormwater into a resource, say community leaders.

The $3.75 million in funding was awarded to the Twain Harte Community Services District through the State Water Resources Control Board’s Stormwater Grant Program. It will be used to construct the Twain Harte Community Stormwater Enhancement Project.

The district called it an “amazing win” for the community in a press release. Also, noting that it “will enhance water quality in our creek and lake, rehabilitate our failing storm drain system, improve water supply reliability, reduce erosion, create fire-safe landscapes and provide fun, interactive education that will empower residents to do the same on their properties.”

The project incorporates simple, innovative stormwater improvements throughout the community, and turns “stormwater into a resource,” advised district officials. They added that coupled with outdoor education labs in Twain Harte Meadows Park makes the “community a model and learning center for other communities.”

The district provided this list of project improvements through four main subprojects shown in the graphic and outlined here:

Twain Harte Stormwater Community Enhancement Project
Twain Harte Stormwater Community Enhancement Project

County Storm Drain Rehabilitation

  • Rehabilitation of deteriorated storm drain from the shopping center to the park, eliminating the risk of dangerous sinkholes, improving water quality, and reducing sedimentation in the creek.
  • New sidewalk and gutters along the east side of Joaquin Gully through downtown to provide better stormwater flows and pedestrian access.



Twain Harte School Stormwater Capture

  • A large tank to capture and clean stormwater from the storm drain, providing water for their field, reducing the need for treated water supply, and reducing creek flows in storms.
  • Several smaller tanks to capture rainwater off building roofs to be used for landscaping, reducing the need for treated water supply.

Twain Harte CSD Office Stormwater Enhancements

  • Removal of paved parking area and installation of a larger permeable parking area to support parking for the fire facility, reducing existing flooding issues.
  • Bioswales to slow stormwater and filter/clean it before it flows downtown and into the creek.
  • Rain tanks to capture rainwater off building roofs to water landscaping and keep area hydrated and more fire safe.

Twain Harte Meadows Park

  • Constructs more than half of the Twain Harte Meadows Park – everything except large outdoor pavilion, bathrooms and parking lot.
  • Recreation and educational demonstration site for a variety of stormwater re-use techniques, including hands-on outdoor learning labs in Meadows Park.

The project is a collaborative effort between Twain Harte CSD, Tuolumne County, Twain Harte School, Tuolumne Stanislaus Integrated Regional Water Management Authority, and Tuolumne County Resources Conservation District. The grant agreement is expected to be finalized in the fall and then get underway.

Meadow Restoration Reflects Collaborative Watershed Efforts

T-Stan IRWMA News

Tori James, MML News Reporter

Sonora, CA — With $12 million in funding, a multi-agency partnership taking a systemic approach to watershed health is literally, applying a “trickle down” approach.

Yesterday, federal, state and local officials had the opportunity to tour one of several local watershed health projects made possible through funding grants administered through the Tuolumne-Stanislaus Integrated Regional Water Management Authority, which help seek monies and develop projects that address water-related issues within the watershed.

Executive Director Lindsay Mattos recounts the group’s foray off Herring Creek Road to visit Coyote and Middle Three meadows, where they viewed completed and in-progress restoration work.

As she explains upfront, “Our role is to provide a space for local agencies, nonprofits and other interested parties to collaborate on watershed health, that includes domestic water, water in the forest — that sort of thing — and we try to plan out projects that benefit each other that all benefit the watershed.”

Effects Filter Downstream 

Continuing, she emphasizes, “Meadow restoration benefits wildlife…provides a slow release of water downstream and acts as a filter to slow sediment.” Meadows also slow water feeding downstream creeks and rivers, reduce flooding and store carbon, which can help mitigate climate change effects.

One in a suite of the $12 million in outlined projects, the meadow restoration and culvert replacement on the Stanislaus National Forest in the Summit Ranger District provided tour goers an up close and in-person look.

Work at Coyote Meadow, which completed last year, included restoration and relocation of a poorly located path in the middle that was degrading the area and interrupting water flow. Among plans over the next two years at Middle Three Meadow, the second stop, are to restore a natural stream so that it functions as it should.

All the projects are being jointly funded by the USDA Forest Service and the Safe Drinking Water, Water Quality and Supply, Flood Control, River and Coastal Protection Bond Act of 2006 through the state’s Department of Water Resources and county’s Resource Conservation District.

The takeaway for Mattos is that her collaborative group helped bring a significant chunk of funding that will benefit residents who live in the Stanislaus and Tuolumne River Watershed.  As she puts it, “We started putting together the application four years ago, got funding two years ago…for us, as a group, it is really exciting to see some be completed…to get to see them.”

ATCAA Receives $720,000

Sonora, CA — The California Department of Water Resources has awarded regional grant money to help low-income residents reduce water and energy costs.

The Amador-Tuolumne Community Action Agency (ATCAA) has received a $720,700 grant to install high efficiency dishwashers, washing machines, low flow faucets and shower heads.

The program will be free to those that meet income requirements and it will help an estimated 378 homes across three counties (Tuolumne, Amador and Calaveras).

Joe Bors, ATCAA’s Energy and Water Conservation Programs Director, says, “It effectively reduces the amount of water used by each family and also reduces energy costs, which is a primary goal of this program.

The grant program is administered via the state’s Department of Water Resources and is concert with the California Air Quality Board efforts.

Goals include reducing approximately 2,400 metric tons of CO2 emissions, 67-million gallons of water, and 2.9 million kilowatt hours, over the lifetime of the products installed in the homes.

Bors says the funding was announced late last week and he estimates it will take between 5-8 weeks to get the new program off and running. For more information on ATCAA’s Energy services, click here.

Detours continue in Quartz-Stent area

Union Democrat staff /

A detour is expected to be in place for several weeks near Jamestown for construction on Tuolumne Utilities District’s $1.6 million water main extension project in the Quartz-Stent area.

As of Monday, Jacksonville Road will be closed to through traffic between Dutch Mine and Stent Cut-Off roads from 7 a.m. to 4 p.m. each day, TUD announced in a news release.

The district stated that roads will remain open throughout the duration of the project for people who live in the area and customers of Pet Vacations at 10225 Karlee Lane.

School bus routes and pickup locations will remain the same, according to TUD.

The project, which began in late November, involves installing about 12,000 linear feet of pipeline that will connect up to 100 properties to the TUD system.

It came together in response to well failures blamed on the drought and the discovery last year of high levels of nitrates and arsenic in the groundwater to a dozen homes.

Funding for the project is through a grant from the California Department of Water Resources and State Water Resources Control Board.

Mozingo Construction Inc., based in Oakdale, is the contractor on the project. Motorists are asked to drive with caution in the area while construction is taking place.
