3.7 Geology and Soils Off‐highway vehicle (OHV) recreation facilities shall be managed for sustainable long‐term prescribed use without generating soil loss that exceeds restorability, and without causing erosion or sedimentation which significantly affects resource values beyond the facilities. Management of OHV facilities shall occur in accordance with Public Resources Code, Sections 5090.2, 5090.35, and 5090.53. The 2008 Soil Conservation Standard and Guidelines provide tools and techniques that may be used to meet the 2008 Standard. Other tools and techniques that are more applicable to specific facility conditions and organizational protocols also may be used as appropriate to comply with the soil standard. OHV BMP Manual for Erosion and Sediment Control The OHV BMP Manual for Erosion and Sediment Control (OHV BMP Manual) (State Parks 2007) provides guidance on selecting, implementing, and maintaining BMPs for OHV‐type facilities and construction activities. BMPs detailed in the manual include BMPs for erosion control (e.g., blankets, mulches, hydroseeding techniques), scour control (e.g., check dams and armoring as in upland swales and ditches), dust control, sediment traps, and waste management. Regional and Local Plans, Policies, Regulations, and Ordinances Because Clay Pit SVRA is owned by the State of California, it is not subject to compliance with Butte County policies or ordinances. However, it is the intent of the OHMVR Division to develop Clay Pit SVRA in a manner compatible with planning values expressed by the surrounding community; therefore, these policies and ordinances were considered as part of this environmental evaluation. The Butte County General Plan 2030 Health and Safety Element addresses seismic and geologic hazards. Goals and policies of the general plan are focused on reducing risk from earthquakes, compliance with the Alquist‐Priolo Act, reducing risks from steep slopes, landslides, erosion, and expansive soils (Goals HS‐6 through HS‐9) (Butte County 2010a:298–299). Butte County regulates septic systems that serve the needs of an individual user (e.g., single residence, office building). Butte County‘s on‐site wastewater ordinance (Chapter 19 of the Butte County Municipal Code) regulates and establishes standards for design, construction, installation, operation, maintenance, monitoring, replacement, alteration, enlargement, repair, and abandonment of on‐site wastewater treatment, conveyance, and dispersal systems. The ordinance also ensures compliance with applicable standards, laws, and guidelines as adopted, and/or modified by the State Water Resources Control Board (SWRCB) or the Central Valley RWQCB. The ordinance requires a site evaluation as part of obtaining an On‐Site Wastewater System Construction Permit and examines factors affecting on‐site wastewater system design including, but not limited to, ground slope, soil textural characteristics, effective soil depth, horizontal setbacks, and available area for 100% system replacement (Butte County Municipal Code, Chapter Clay Pit State Vehicular Recreation Area February 2012 3.7-4 Draft EIR
3.7 Geology and Soils 19, On‐Site Wastewater Systems). Because no state‐wide septic regulations apply, the OHMVR Division will comply with the local Butte County on‐site wastewater ordinance for planning purposes at Clay Pit SVRA. 3.7.3 Thresholds of Significance The significance criteria for this analysis are based on the environmental checklist in Appendix G of the State CEQA Guidelines, as amended. Implementation of the Clay Pit SVRA General Plan, including construction and operation of the headquarters facilities, would have significant environmental impacts related to geology and soils if it would: expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving the following: rupture of known earthquake fault, as delineated on the most recent Alquist‐Priolo Earthquake Fault Zoning Map used by the State Geologist for the area or based on other substantial evidence of a known fault; strong seismic ground shaking; seismic‐related ground failure, including liquefaction; or landslides; result in substantial soil erosion or the loss of topsoil; be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project and potentially result in on‐ or off‐site landslides, lateral spreading, subsidence, liquefaction or collapse; be located on expansive soil, as defined in Table 18‐1‐B of the UBC (1994), creating substantial risks to life or property; or have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water. 3.7.4 Environmental Evaluation Evaluation Methodology This section addresses issues related to geologic hazards, specifically seismicity and soil erosion. Effects associated with geology and soils that could result from project‐related activities were evaluated based on expected construction practices, materials used to construct the proposed improvements, and the nature of the proposed activities on the site.
