Asbestos Removal in Folsom, CA

From a School Site to a Countywide Map

The 2004 discovery at Broadstone Parkway and Golf Links Road set off a chain of agency work. Sac Metro Air District issued Advisory 04-05 that September, naming the Copper Hill volcanic unit and flagging the Gopher Ridge volcanic unit as a possible source too. In August 2005 the district made a preliminary determination about both units, and in 2006 the California Geological Survey published Special Report 192, which mapped parts of eastern Sacramento County as moderately likely to contain asbestos. The district now keeps a parcel map built on that report, covering the eastern part of the county, Folsom and Rancho Murieta.

We have not checked which Folsom neighborhoods fall on that map, and this page does not name any beyond the documented school site. Look up your own parcel with the district before planning soil work.

The State Dust Rule for Construction

The rule that applies to mapped ground is CARB’s Airborne Toxic Control Measure for Construction, Grading, Quarrying and Surface Mining, 17 CCR 93105, adopted in 2002 and updated in 2004. It is not limited to big subdivisions. Under it:

• the measure applies to a project of any size on a mapped parcel;
• before work starts, the owner submits an Asbestos Dust Mitigation Plan to Sac Metro Air District, or a registered geologist’s evaluation showing the soil is at or below 0.25% asbestos;
• projects disturbing more than one acre carry extra notification requirements;
• the district lists the plan fee at $571.11 plus $29.98 per acre and the geologic evaluation at $738.89 on its Asbestos in Soil page (read October 2026), with review in 2 business days.

Pool excavation, trenching for utilities, pad grading and retaining-wall footings are all soil disturbance. None of this involves the house itself.

The Buildings Are a Smaller Question

Just 13% of Folsom homes were built before 1980, and 5% before 1960 (ACS 2020–2024), most of them in and around the historic district on Sutter Street. Much of the rest is 1980s to 2010s subdivisions, with new building still going on in Folsom Ranch south of US-50. For older commercial buildings downtown, the usual Rule 902 survey and notification steps apply, the same as anywhere else in Sacramento County.

Folsom Projects

Older storefronts and homes near Sutter Street are where building-material testing and old tile and mastic removal come up. Taking down an older outbuilding still runs through abatement before demolition and a Rule 902 notification. The soil requirements continue east into El Dorado Hills, under a different county’s air district and its own trigger.
