Cumulative Effects

A major concern for Resist Density is how all of the current projects will impact traffic and road safety, the environment, sewage capacity and the semi-rural nature of the Midcoast. Who is looking at the big picture?

How much building can our infrastructure support? The San Mateo County coast is unique in that we have only one road in, through and out, with no alternative routes. Decades ago, voters county-wide chose to preserve the coast by voting against efforts to build more freeway access in favor of a tunnel through Montara Mountain. In addition, thanks to the efforts of POST and the advocacy of local organizations and community members, hundreds of acres of coastal land have been preserved as open space. These factors strictly limit the size and types of building projects that make sense for our small coastside communities.

With Highway 1 as the ONLY road that offers access and exit and the ever-increasing influx of tourists and visitors, there is a real danger with further escalation of density through the Montara to Half Moon Bay corridor. The cumulative effects of large building projects in this area are not being adequately addressed in light of its fixed infrastructure. This danger is further compounded by the looming probability of rising seas, wildfire risks, and earthquakes.

Current List of Large Projects on the Coast

Large projects at different planning / approval stages will significantly worsen the traffic and infrastructure situation on the Coast and Highway 1. Projects being proposed and already approved reveal that there is a lack of consideration for the total effect of all these projects:


  • 1 (2) Hotels in Montara

Moss Beach

  • Big Wave: Total of 8 buildings including a large Office Park (the 5 office buildings alone equate the size of 1.5 Walmarts) plus housing, boat storage, parking for approx 500 cars

  • MidPen: Multi-unit housing project across from the Montara Lighthouse

El Granada

  • RV park - 50 sites (Harbor Village - corner of Capistrano and Hwy 1)

Half Moon Bay

  • Dunes Beach Hotel / Surf Beach RV Park: 200+ room hotel, 15,000 sf conference center, 170+ space RV park located at Young Ave and HWY 1

  • Pacific Ridge: Residential project next to Half Moon Bay High School with 63 homes   

  • Podesta Planned Unit Development: 34.5 acres slated for residential pilot program, at intersection of northern end of Main Street and HWY 1

  • Best Western Hotel: 46 Rooms south of 92 on HWY 1 

  • Hyatt Hotel: 141 Rooms with Conference Center plus 2,700 SF retail building and 195 parking spots, located at southern gateway of Half Moon Bay at Main Street and HWY1


Plus the annual infill of homes, second units, and approximately 3 million visitors to the Coastside per year.

Studies of traffic and project proposals do not address the cumulative impacts of projects - No assessments are being made of the big picture. The cumulative effects of these projects will dramatically increase traffic, pollution, environmental stress and the breakdown of this coastal community. Decisions on these developments are seemingly being made in a vacuum.

Traffic is choking the coast. There are no alternate routes - We have one road in, through and out.

HWY 1 suffers major traffic congestion

Safety is a key concern for coastside residents. With increased traffic since the tunnel opened in 2013, access to the coast has diminished.
