Merriam Mountains is a massive development proposed for 2,327 acres in the predominantly rural and agricultural area north of Deer Springs Road and just west of Interstate 15 in northern San Diego County.

In opposition to this proposed development, this site has been created by the Citizens Against Stonegate Traffic (CAST) - a coalition of San Diego County residents concerned with the increased traffic impacts from this project on area roads and freeways, including Interstate 15 and State Route 78.

CAST is specifically concerned with the significant traffic impacts throughout the County that would result from this development, in addition to negative impacts to local infrastructure, fire safety, water supply, local schools and the environment. We hope to reach out to all San Diego County residents and urge you to join us in our effort to stop the Merriam Mountains project from further congesting our County's roads and freeways and disrupting the quality of life in our communities.
