Save Our St Vrain Valley SOSVV SOSVV, Inc., we're Grass-Roots, Community Powered, Environmental Action. Vrain Valley. AI appealed his decision to the Board of Adjustment, BOA in October 2020.

There are many who cherish the agricultural open space and recreational opportunities in Hygiene & Lyons. Many are still unaware that there have been four industrial proposals in the area by mining behemoths in the last five years, collectively and individually, threatening to spot zone this valley– the least developed river valley in the Front Range, into an industrial wasteland. SOSVV, Inc forme

d in the Spring 2017, inspired by Martin Marietta Materials January 2017 site-plan approval and expectation to commence deep pit gravel mining of ~800 acres based on a Special Use, SU, permit from last century in the geologically unique St. Marietta's Special Use had been issued to their predecessors in interest over two decades ago in 1997-98. Upon learning of Marietta and Land Use plans to gravel mine hundreds of acres, SOSVV asserted that SU 96-18 had expired based on the Five Year Lapse provision in the Boulder Land Use Code. In 2017 Boulder County had never applied the Five Year Lapse provision, promulgated in the 1980’s, to any SU. SOSVV appealed Director Case's determination to the Board of Adjustment, BOA. Our attorneys persuaded 3/5 BOA judges, but a supreme majority was required to overturn the Land Use Director's determination. SOSVV appealed to District Court and ultimately to CO Court of Appeals, whose three judges agreed unanimously with SOSVV and overruled the Director's determination. Marietta then appealed that decision to the CO Supreme Court, who also agreed with SOSVV and the CO Appeals Court. A couple of years since starting our advocacy for upholding the expiration Marietta's SU 96-18, Aggregate Industries, AI, wanted to resurrect their dormant Special Use mining permit from 1998, the project area of hundreds of acres, is located near Pella Crossings– the recreational hot spot where Boudler County residents come to "Enjoy the peaceful waters of Pella Crossing where you can escape the urban pace" according to Boulder County. SOSVV advocated for upholding the expiration of AI's SU, and Land Use Director, Dale Case, agreed with SOSVV, making a Landmark decision in 2020 to apply the Five Year Lapse provision, and setting a legal precedent with far-reaching influences, well beyond Boulder County. SOSVV's attorneys, Ireland Stapleton Pryor & Pascoe, once again made an excellent legal argument in favor of applying the Lapse Provision and upholding the expiration of SU permits, unanimously convincing the five BOA members. A.I. went on to appeal the BOA's determination to District Court, but they vacated their appeal once SOSVV prevailed at the CO Supreme Court on the Martin Marietta SU permit in 2021. During this period, in 2019 Cemex proposed converting a couple of exhausted mining quarries into a public shooting range at the base of the St Vrain River. SOSVV launched a campaign "Shoot it Down" (watch @ FB videos), and effectively dodged a bullet, protecting wildlife and our peaceful community in northern Boudler County. Cemex concurrently proposed extending their Dowe Flats permit by 100%, another 25 years, beyond the expected December 31, 2021 expected expiration. SOSVV opposed the permit extension proposal based on the original agreements made and the expressed intent of those agreements between the County and Cemex. In an official letter dated June 14, 2019 to then Cemex Plant Manager, Dr Uwe Lubjuhn, Director Case, stated that “September 30, 2022 is the date when mining must cease [at Dowe Flats]”. In May 2022, after two years apparently positioning and working behind the scenes, buying the Covenant sited in the Resolution, Cemex has applied to extend its SU for mining Dowe Flats by 60%, an additional 15 years! In May 2022, Marietta stated that they will appeal Director Case's determination reversing his 2017 approval to the BOA. The BOA hearing date is pending. To residents, visitors, and many cyclists that flock to this area, the Gateway of the Rockies welcomes migratory birds annually, houses endangered species, the mining activity based on expired or expiring permits has anticipated negative impacts, including but not limited to: air quality, and health effects (from fugitive dust events that contain a crystalline silica and more https://pubmed.ncbi.nlm.nih.gov/15448758/ ), coupled with high winds making fugitive dust events virtually impossible to prevent, noise and light pollution, etc. According to Boulder County's data, Cemex’s Environmental Impact is rated the No. 1 polluter of Co2 emissions; this fact cannot be overstated. CEMEX is the #1 Polluter in Boulder County. Cemex Represents 7.3% of county Greenhouse Gas Emissions in Boulder County
Cemex plant Produces 17X the emissions as the entire Town of Lyons combined
Cemex Emits 357,101 mtC02e annually, the equivalent of ~25,000 Boulder County residents (1,3)
Cemex Publicly stated it is going to operate indefinitely
Over next 30 years, Cemex is expected to emit 10 million mtC02e
Boulder County committed to reduce emissions from 15 mtCO2e => 7 mtCO2e per capita by the year 2030. CEMEX Lyons plant represents a full 1 mtCO2e per capita or 12.5% of the 2030 reduction target. Help SOSVV advocate for Rights of Nature and Community Rights- here’s how:

The St Vrain watershed cannot walk into a public hearing and advocate for itself. But we can.

On November 4, 2026, Boulder County will hold a public hearing that could help shape the future of the St. Vrain Valley and the protections surrounding it.

The St Vrain is far more than the beautiful river running through our valley. Its water supports local farms and agriculture, wildlife and habitat, our communities, and the generations who will inherit this place after us.

This is why we are asking our community to show up.

A public hearing gives residents a rare opportunity to stand together, speak directly to local decision-makers, and make it unmistakably clear **in person** that protecting the health of our watershed is a community priority.

You do not need to be an expert. You do not need to understand every regulation or know every detail of this fight. If you care about this valley, its water, and its future, your presence matters.

Mark your calendar for November 4 and please join us.

Our water. Our community. Our future.

This is the St. Vrain watershed. And its water is worth protecting.

Robin Lucas Photography took this photograph along the St. Vrain River at Peaceful Valley, just upstream from the farms, wildlife, communities and ecosystems that depend on this watershed.

It’s easy to look at water like this and assume it will always be here. But in Colorado, every gallon matters.

That is why we’re beginning:


A quick series from our grassroots org sharing documented facts about the St. Vrain Valley, its watershed, and the industrial activity occurring within it.

We want our community to have the information for itself. Please share these bits of info with your neighbors and friends living in .

According to CEMEX’s independently verified Environmental Product Declaration for the Lyons cement plant, producing one metric tonne of cement consumes approximately 2.01–2.37 cubic meters of freshwater. The same document lists the plant’s annual production capacity at approximately 400,000 metric tonnes.

At full production capacity, that equates to roughly 200+ million gallons of freshwater.

Two hundred million gallons.

Here in the St. Vrain Valley, that water isn’t simply an industrial input.

It is the river running through this photograph.
It irrigates agricultural land.
It sustains wildlife and riparian habitat.
It moves through the communities downstream.
It is part of what makes this valley home.

In a water-limited state like Colorado, the use of hundreds of millions of gallons of freshwater deserves public understanding and scrutiny. We should know how our natural resources are being used, at what scale, and what that means for the valley that provides them.

This series is about making that information accessible.

Same concerns we have in 2026! It’s time to hold the county accountable to its April 2024 Cease & Desist order. Director of Land Use, Dale Case rescinded the order in July 2026. It’s time to cease operations at this vintage plant in unincorporated Boulder. If you agree, join SOSVV & the Good Neighbors of Lyons on October 7th Board of Adjustment (BOA) appeals hearing. Follow us for upcoming details. And if you‘re able, please contribute 26 for 2026 to be the year transformation happens. $26 for a month-for the next five months will fund our legal efforts to decommission the “Lyons’ cement plant- the No1 Co2 polluter in Boulder County. For less than the cost of a cup of coffee a day- you’re empowering environmental action, holding Cemex accountable for its non-conforming uses, removing 300+ daily gondola trucks off our roads & highways, ensuring better air quality and public health. We’re grass-roots, Community-Powered environmental-action.
