Sensitive Receptors include children, elderly, asthmatics, and others who are at a heightened risk of negative health outcomes due to exposure to air pollution.

The Community Development Director may increase the screening area distance on a case-by-case basis if an unusually large source of hazardous emissions is proposed or currently exists. Measures identified by the health risk assessment to reduce potential exposure to particulate matter, carbon monoxide, diesel fumes, and other potential health hazards (such as air filtration systems) shall be incorporated into the building permit plans and installed prior to project occupancy and use.

E. Design Standards. Projects shall be subject to design review per Larkspur Municipal Code Chapter 18.64. Particular emphasis shall be placed on any adopted design guidelines.

3. Activities requiring outdoor storage must be screened from view to the extent feasible. Machinery or equipment, which, because of size and/or function, cannot practically be installed within an enclosed building, shall also be screened to the extent feasible.

L. Minimize Vibration Impacts. New development shall minimize vibration impacts to adjacent uses during demolition and construction. For structures listed on the official historic resources inventory, determined to be eligible for inclusion on the historic resources inventory, or located within the H District, a vibration limit of 0.08 in/sec PPV (peak particle velocity) will be used to minimize the potential for cosmetic damage to the building. A vibration limit of 0.30 in/sec PPV will be used to minimize the potential for cosmetic damage at buildings of normal conventional construction. Prior to issuance of any demolition, grading, or building permits (whichever occur first), the project applicant shall provide a vibration construction plan to reduce construction impacts at buildings where vibration level would exceed the vibration limits.
