HAZ-12.3 Siting of Essential Facilities

by

The County should not site essential facilities, public safety or emergency service facilities, special occupancy structures, or hazardous materials storage facilities in areas subject to the following hazard areas, as defined in the Ventura County Multi-Jurisdictional Hazard Mitigation Plan (Ventura County Sheriff’s Office of Emergency Services), unless the structure is designed to mitigate the hazard:  

  • in tsunami hazard areas, as defined in the Tsunami Operational Area Response Guide (Ventura County Sheriff’s Office of Emergency Services);  
  • geologic or seismic hazard areas;  
  • areas subject to liquefaction, landslide, or seiche hazards; and  
  • subsidence or hydroconsolidation.

AG-1.1 Agricultural Land Protection and Preservation

by

The County shall continue to protect and preserve agricultural land by directing growth away from productive agricultural lands into cities, unincorporated urban areas, or existing communities and by supporting the acquisition or voluntary dedication of agriculture conservation easements.

AG-1.2 Agricultural Land Use Designation

by

The County shall ensure that discretionary development located on land designated as Agricultural on the General Plan Land Use Diagram and identified as Prime Farmland or Farmland of Statewide Importance on the State’s Important Farmland Inventory is planned and designed to remove as little land as possible from potential agricultural production and to minimize impacts on topsoil.

HAZ-9.2 Noise Compatibility Standards

by

The County shall review discretionary development for noise compatibility with surrounding uses. The County shall determine noise compatibility based on the following standards:

1. New noise sensitive uses proposed to be located near highways, truck routes, heavy industrial activities and other relatively continuous noise sources shall incorporate noise control measures so that indoor noise levels in habitable rooms do not exceed a Community Noise Equivalent Level (CNEL) of 45 and outdoor noise levels do not exceed a CNEL of 60 or Leq1H of 65 dB(A) during any hour.

2. New noise sensitive uses proposed to be located near railroads shall incorporate noise control measures so that indoor noise levels in habitable rooms do not exceed a Community Noise Equivalent Level (CNEL) of 45 and outdoor noise levels do not exceed L10 of 60 dB(A).

3. New noise sensitive uses proposed to be located near airports:

a. Shall be prohibited if they are in a Community Noise Equivalent Level (CNEL) 65 dB or greater noise contour; or

b. Shall be permitted in the Community Noise Equivalent Level (CNEL) 60 dB to CNEL 65 dB noise contour area only if means will be taken to ensure interior noise levels of CNEL 45 dB or less.

4. New noise generators, proposed to be located near any noise sensitive use, shall incorporate noise control measures so that ongoing outdoor noise levels received by the noise sensitive receptor, measured at the exterior wall of the building, does not exceed any of the following standards:

a. Leq1H of 55dB(A) or ambient noise level plus 3dB(A), whichever is greater, during any hour from 6:00 a.m. to 7:00 p.m.;

b. Leq1H of 50dB(A) or ambient noise level plus 3dB(A), whichever is greater, during any hour from 7:00 p.m. to 10:00 p.m.; and

c. Leq1H of 45dB(A) or ambient noise level plus 3dB(A), whichever is greater, during any hour from 10:00 p.m. to 6:00 a.m.

5. Construction noise and vibration shall be evaluated and, if necessary, mitigated in accordance with the Construction Noise Threshold Criteria and Control Plan. (RDR)

Notes: SR = State Route; dBA = a-weighted decibels;  

Gray shaded cells reflect roadway segments exceeding 60 dBA CNEL at 50 feet from the roadway centerline.  

All modeling assumes average pavement, level roadways (less than 1.5% grade), constant traffic flow, and does not account for shielding of any type or finite roadway adjustments. All noise levels are reported as A-weighted noise levels.

HAZ-9.3 Development Along Travel Routes

by

The County shall evaluate discretionary development for noise generated by project-related traffic along the travel route to the nearest intersection which allows for movement of traffic in multiple directions. In all cases, the evaluation of project-related roadway noise shall be evaluated along the travel route(s) within 1,600 feet of the project site.

HAZ-9.4 Acoustical Analysis Required

by

The County shall require an acoustical analysis by a qualified acoustical engineer for discretionary development involving noise exposure or noise generation in excess of the established standards. The analysis shall provide documentation of existing and projected noise levels at on-site and off-site receptors and shall recommend noise control measures for mitigating adverse impacts.
