ECOS letter on Water Agencies’ Participation in Sacramento Area Turf Replacement Study

On February 14, 2022, the Environmental Council of Sacramento submitted a letter to Sacramento Area Water Agencies regarding their participation in a Sacramento Area Turf Replacement Study. Below is the content of the letter.

To: Sacramento Area RWA Water Agencies

The Environmental Council of Sacramento’s Water Committee has begun a project to calculate the potential water savings from conversion of ornamental grasses (turf) to drought-tolerant landscaping in the American River water purveyor area (i.e. Regional Water Authority member agencies). We are interested in your input and participation in this study. This letter describes the study plan. For more information or to participate, please contact Katrina Harrison, PE, ECOS Water Committee member and Project Manager, at kandchf[at]gmail[dot]com or (408) 644-9108.

The Water Committee has met with representatives of the Department of Water Resources (DWR) to share methodologies and inquire about data sources. DWR staff has been helpful but has suggested relying on publicly available datasets. Therefore, Water Committee plans to calculate the area of current ornamental grasses using 2019 or 2020 publicly available fine scale (~1 foot pixel size wherever possible) aerial and infrared imagery. Aerial images include National Agriculture Imagery Program (NAIP), Bing imagery, Planet, and NearMap.

This imagery dataset will be analyzed using the machine learning, or neural net, algorithms of the software program eCognition to determine turf grass area. Land classifications will be digitized in several sample areas, and the computer model will be trained using those areas including calculating the Normalized Difference Vegetation Index (NDVI) as well as a Tree Grass Difference Index. The aerial imagery processing will be validated manually to develop a calculation of the accuracy and estimated error bounds of the analysis.

Following calculation of the area of turf grass, ECOS Water Committee members plan to use California Native Plant Society information on the evapotranspiration and density of different plant palettes – lawn versus drought-tolerant landscaping – to determine the difference in water use. This difference will be multiplied by the area to determine potential water savings.

We appreciate any insight or methodology suggestions you may have. We would like to share our draft results with study participants and will make the final product available to the Water Forum for its consideration in the ongoing Water Forum 2 discussions. If you have an interest in participating, please contact Katrina Harrison at kandchf[at]gmail[dot]com or Ted Rauh at tnrauh[at]att[dot]net. We would appreciate hearing from you before the end of February so that your input can be included in the study.

If the Sierra snowpack vanishes as feared, California will need ideas like this for water

By the Sacramento Bee Editorial Board | February 2, 2022 | The Sacramento Bee

Sacramento — which once only had to worry about seasonal floods — now worries each year about delivering water to its citizens in a hotter and drier California. But there is a way for Sacramento to capture rain and snow, and for the broader region to keep surface reservoirs like Folsom and Oroville lakes nearly full. This same technique could help Sacramento capture enough water to share with neighboring areas in dry years, as well as to store it when we need it most.

Environmentalists of the Year Film Premiere!

ECOS is excited to share with you our 2021 Environmentalist of the Year Awards film, made in lieu of the annual in-person event. Enjoy the film below!


2021 Environmentalists of the Year


Environmentalist of the Year

Dr. Michelle Stevens

Dr. Michelle Stevens, a professor in the Environmental Studies Department at CSUS, has been leading the Bushy Lake Restoration Project along the lower American River Parkway, which protects, studies, and restores Sacramento’s riparian ecosystem. Michelle was able to “sell” this idea to the local community, a myriad of stakeholders, regional professionals and experts, and fellow colleagues. Michelle started with planting a few plants that are important to native peoples in the region, and nurtured it until it grew into a grant-funded restoration plan involving CSUS students and volunteers. Her work is informed and guided in uplifting the historic indigenous practices and culture of traditional ecological knowledge, and provides a hands-on opportunity for college students through CSUS and volunteers. In 2019, this project won an award at the annual CSU-wide Student Research Competition.


Environmentalist of the Year

Brandon Rose

Brandon Rose was ECOS President 2016-2017. During his tenure, ECOS put on a California Environmental Quality Act (CEQA) workshop, which helped to attract and train volunteers. ECOS supported Sacramento’s plastic bag ban and ethics reform ordinances. Under his leadership, ECOS also helped the City obtain a $44 million “Green City” grant to construct electric vehicle charging stations and acquire electric vehicle fleets for car sharing programs in disadvantaged neighborhoods. Also during Brandon’s board presidency, ECOS worked with Wilton Rancheria to locate their proposed casino within the County of Sacramento’s Urban Service Area, rather than a rural area. In 2017, ECOS sued Caltrans over its approval of extra lanes on US 50 without considering the environmental impacts of increased traffic, which led to a settlement providing funding for transit. Later that year, Brandon was elected to the Sacramento Municipal Utility District (SMUD) board, which has since committed to carbon neutrality by 2030.


Early Career Environmentalist

Moiz Mir

Moiz Mir was the president of the Environmental Student Organization at CSUS, 2017–2019. As an intern at the Sacramento Mayor’s Office, he organized youth summits to include students’ voices in the Mayors’ Commission on Climate Change, and served on the Commission’s Community Health & Resiliency and Equity Technical Advisory Committees. He co-won a statewide “Best Practice in Student Sustainability Leadership Award” for organizing the CSUS Student Summit on Climate Change. As a student, Moiz worked with Michelle Stevens, supervising student plant experiments at Bushy Lake. With Sunrise Movement Sacramento, Moiz is engaging youth in climate justice action. Moiz recently became the first staff at 350 Sacramento, where he developed a new after-school student climate organizing program.


Climate Hero

Anne Stausboll

Anne Stausboll chaired the Mayors’ Commission on Climate Change, which presented its recommendations in June 2020. She obtained a unanimous vote on a very progressive set of recommendations, which took two years to develop. The goal is to achieve carbon neutrality in Sacramento and West Sacramento, by 2045. Anne made sure the Commission reviewed and considered everything through a lens of racial and income equity. She is inspiring us to be active with the City of Sacramento to ensure that these recommendations are incorporated into the Cities’ Climate Action Plans, and into appropriate ordinances and other city actions. As Anne says, “it is a crisis situation, and we need to act now. We want the city to start seriously adopting and acting on the recommendations. Now. It’s not something that can wait.”

Press release re American River bridge lawsuit by ECOS

April 6, 2021

On March 29, 2021, the Environmental Council of Sacramento (ECOS) filed a Petition for Writ of Mandate with the Sacramento County Superior Court challenging Caltrans’ approval of the Initial Study/Environmental Assessment with a Mitigated Negative Declaration (IS/MND) for a project to widen the Capital City Freeway (SR 51) bridge over the American River.

The IS/MND does not provide adequate environmental review under CEQA, in that it fails to provide an adequate project description and piecemeals environmental review of further planned widening of SR 51. Furthermore, this project may have significant impacts to greenhouse gas emissions (GHG) and climate change. ECOS seeks a determination from the Superior Court that Caltrans’ approval of the project is invalid and void and that the Mitigated Negative Declaration fails to satisfy the requirements of CEQA Guidelines (Title 14, California Code of Regulations, section 15000 et seq.).

Since 1966, the bridge has had three lanes in each direction…. [read more]
