Dear Ms. Leung:
San Mateo County’s Notice of Preparation of the Draft Environmental Impact Report for the Big Wave Wellness Center and Office Park; SCH# 2008102109
The California Department of Transportation (Caltrans), Division of Aeronautics (Division), reviewed the above-referenced document with respect to airport-related noise and safety impacts and regional aviation land use planning issues pursuant to the California Environmental Quality Act (CEQA). The Division has technical expertise in the areas of airport operations safety, noise and airport land use compatibility. We are a funding agency for airport projects and we have permit authority for public-use and special-use airports and heliports. We offer the following comments for your consideration.
The proposal will include "housing and employment opportunities for low-income developmentally disabled (DD) children and adults." The two primary components include a "Wellness Center” and "Office Park." The project site is located immediately adjacent to southwest boundary of the Half Moon Bay Airport.
Half Moon Bay Airport provides a variety of emergency service and response functions including: Air-Ambulance and Medivac flights; law enforcement and homeland security patrols; Coast Guard sea-rescue operations; and use as a disaster relief staging site for the airlifting of emergency supplies in the event that roads are closed during a disaster or emergency. Half Moon Bay is an active airport, with approximately 80-based aircraft, over 60,000 annual operations and several aviation related businesses.
A portion of the project site appears to be within the Approach Protection Zone (APZ) for Half Moon Bay Airport as designated in the San Mateo County Comprehensive Airport Land Use Plan (CALUP). The CALUP recommends against residential uses and business uses within the APZ. Protecting people and property on the ground from the potential consequences of near-airport aircraft accidents is a fundamental land use compatibility-planning objective. While the chance of an aircraft injuring someone on the ground is historically quite low, an aircraft accident is a high consequence event. To protect people and property on the ground from the risks of near-airport aircraft accidents, some form of restrictions on land use are essential. The two principal methods for reducing the risk of injury and property damage on the ground are to limit the number of persons in an area and to limit the area covered by occupied structures. This should be addressed in the Draft Environmental Impact Report (DEIR).
The northern third of the project site also appears to be within an area identified as "extremely noise sensitive areas" on the Half Moon Bay Airport-Noise Abatement Procedures. It is likely that some future residents and tenants will be annoyed by aircraft noise in this area. A thorough airport-related noise analysis should be included in the DEIR.
The proposal should also be submitted to the San Mateo County Airport Land Use Commission (ALUC) for a consistency determination. The proposal must also be coordinated with Half Moon Bay Airport staff to ensure that the proposal will be compatible with future as well as existing airport operations.
State Public Utilities Code Section 21659 prohibits structural hazards near airports. In accordance with Federal Aviation Regulation, Part 77 "Objects Affecting Navigable Airspace" a Notice of Proposed Construction or Alteration (Form 7460-1) may be required by the Federal Aviation Administration (FAA). Form 7460-1 is available on-line at https://oeaaa.faa.gov/oeaaa/external/portal.jsp and should be submitted electronically to the FAA.
Business and Professions Code Section 11010 and Civil Code Sections 1102.6, 1103.4, and 1353 address buyer notification requirements for lands around airports and are available on-line at http://www.leginfo.ca.gov/calaw.html. Any person who intends to offer subdivided lands, common interest developments and residential properties for sale or lease within an airport influence area is required to disclose that fact to the person buying the property.
The protection of airports from incompatible land use encroachment is vital to California's economic future, Half Moon Bay Airport is an economic asset that should be protected through effective airport land use compatibility planning and awareness. Although the need for compatible and safe land uses near airports is both a local and State issue, airport staff, airport land use commissions and airport land use compatibility plans are key to protecting an airport and the people residing and working in the vicinity of an airport. Consideration given to the issue of compatible land uses in the vicinity of an airport should help to relieve future conflicts between airports and their neighbors.
These comments reflect the areas of concern to the Division with respect to airport-related noise and safety impacts and regional airport land use planning issues. We advise you to contact our Caltrans District 4 office concerning surface transportation issues.
Thank you for the opportunity to review and comment on this proposal. If you have any questions, please call me at (916) 654-5314.
Sincerely,
SANDY HESNARD
