BACKGROUND: 1. Name of Proponent: County of Butte 2. Address: 7 County Center Drive. Oroville, CA 95965 Phone: (530) 538-7601 3. Name of Proposal, if applicable: Research & Business Park General Plan Amendment and Rezoning 4. Type of Project: General Plan Amendment and Zoning Revision 5. Project Description and Location of Parcel(s): The proposed Project consists of a new General Plan land use designation and a new Zoning district, both of which are entitled Research & Business Park (RBP). This new General Plan land use designation and Zoning district are intended to provide for development of specialized industrial, research, and commercial projects at least 200 acres in area in locations that meet the Site Designation Criteria contained in the RBP General Plan land use designation. The proposed General Plan and Zoning designations may be applied to lands anywhere within the County that meet the Site Designation Criteria and can be developed according to the requirements of the Zoning district. The process of identifying candidate sites that meet the General Plan criteria has not been undertaken, and sites that meet these criteria have not been identified. 6. Assessor's Parcel Numbers: Not applicable. 7. Date Checklist Submitted: September 24, 1999 II. DETERMINATION: On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. _X_ I find that although the proposed project COULD have a significant effect on the environment, there will NOT be a significant effect in this case because the mitigation measures described on an attached sheet have been added to the project. A NEGATIVE DECLARATION with mitigations) will be prepared. 1 Initial Study -Research & Business Park GPA/Rezoning I find that the proposed project COULD have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the praposed project MAY have a "potentially significant impact" or "potentially significant unless mitigated" impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been adequately addressed by mitigation measures based on the earlier analysis as described on attached sheets. AN ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects a} have been analyzed in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required. ~~t ~ ~~- ~'~~ ~ ~. ~ Prepared ,~ i Reviewed by: Date Date 2 Initial Study -Research & Business Park GPAtRezoning III. ENVIRONMENTAL FACTORS POTENTIALLY AFFECTED: The environmental factors checked below could be potentially affected by this project, involving at least one impact that is a "Potentially Significant Impact" as indicated by the checklist on the following pages. x Aesthetics x Hazards and Hazardous - Public Services _ Agricultural Resources Materials Recreation X Air Quality X Hydrology and Water Quality = Transportation(Traffc x Biological Resources =Land Use and Planning = Utilities and Service x Cultural Resources _ Mineral Resources Systems X Geology and Soils =Noise x Mandatory Findings of - Population and Housing Significance EVALUATION OF ENVIRONMENTAL IMPACTS: 1 } A brief explanation is required for all answers except "No Impact" answers that are adequately supported by the information sources a lead agency cites in the parentheses following each question. A "No Impact" answer is adequately supported if the referenced information sources show that the impact simply does not apply to projects like the one involved (e.g. the project falls outside a fault rupture zone}. A "No Impact" answer should be explained where it is based on project-specific screening analysis). 2} All answers must take account of the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and construction as well as operational impacts. 3} "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect is significant if there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4) "Potentially Significant Unless Mitigation Incorporated" applies where the incorporation of mitigation measures has reduced an effect from "Potentially Significant Impact" to a "Less than Significant Impact." The lead agency must describe the mitigation measures, and briefly explain how they reduce the effect to a less than significant level (mitigation measures from Section XVII, "Earlier Analysis," may be cross-referenced}. 5) Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in a earlier EIR or negative declaration. Section 15063(c){3)(D). Earlier analyses are discussed in Section XVII at the end of the checklist. 6) Lead agencies are encouraged to incorporate into the checklist references to information sources for potential impacts (e.g. general plans, zoning ordinances}. Reference to a previously prepared or outside document should, where appropriate, include a reference to the page or pages where the statement is substantiated. A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 3 Initial Study -Research & Business Park GPA/Rezoning IV. ENVIRONMENTAL IMPACTS: Aesthetics Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a) Have a substantial adverse effect on a x scenic vista? b) Substantially damage scenic resources, x including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? c) Substantially degrade the existing visual x character or quality of the site and its surroundings? d) Create a new source of substantial light or x glare which would adversely affect day or ni httime views in the area? Discussion: a) Nave a substantial adverse effect on a scenic vista? The Project will provide for the development of large (200 acres or larger) sites and the construction of buildings that may be up to 40 feet high and cover large areas. Ground coverage is proposed to be controlled by floor area ratio (FAR); for example, aone- story building on a one-acre parcel could cover 21,632 square feet. However, the proposed Zoning district requires minimum open space of 30 percent far lots 1 to 10 acres in size and 40 percent for lots 10 acres and larger. Development as provided for in the proposed General Plan and Zoning could result in a significant change in the visual character of sites designated for Research & Business Park development. The majority of candidate development areas are likely to consist of open annual grassland that is readily visible from adjoining roads. Where development is permitted, a significant portion of the natural features of the site will be replaced by structures, pavement, and ornamental landscaping. Visual impact of development will be mitigated, in part, by certain provisions of the proposed Zoning district, including minimum open space requirements (noted above} and the requirement for preparation of and adherence to design guidelines. Design guidelines are required to address topic areas identified in the proposed Zoning district, including but not limited to, architecture, landscaping, signage, and lighting. The following mitigation measure is recommended to reduce potential visual impacts to aless-than-significant level: 4 Initial Study -Research & Business Park GPA/Rezoning Mitigation Measures: 1. A detailed environmental analysis which addresses aesthetic aspects of development applications shall occur as part of the Master Development Plan process. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a state scenic highway? Refer to discussion in items "a" and "c". c) Substantially degrade the existing visual character or quality of the site and its surroundings? As noted in item "a", the proposed General Plan and Zoning designations will provide for development of projects that are subject to stringent development standards and design guidelines. Therefore, a substantial degradation in the existing visual character is unlikely. However, the degree to which a particular project may be visually acceptable or unacceptable is a matter of personal opinion, and can be influenced by a variety of factors. d) Create a new source of substantial fight ar glare which would adversely affect day or nighttime views in the area? The Project will allow for the introduction of nighttime lighting and daytime glare from sunlight reflection in areas where light and reflection presently are non-existent. As noted above, the proposed Zoning Ordinance requires that design guidelines be prepared that address, among other topics, lighting. Mitigation Measure 1 will ensure that potential lighting and glare impacts are addressed. Agricultural Resources In determining whether impacts to agricultural resources are significant environmental effects, lead agencies may refer to the California Agricultural Land Evaluation and Site Assessment Model (1997) prepared by the California Department of Conservation as an optional model to use in assessing impacts on agriculture and farmland. Would the project: 5 Initial Study -Research & Business Park GPAlRezoning Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incar orated a) Convert Prime Farmland, Unique Farmland, x or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b) Conflict with existing zoning for agricultural x use, or a Williamson Act contract? c) Involve other changes in the existing x environment which, due to their location or nature, could result in conversion of Farmland, to non-a ricultural use? Discussion: a) Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? The minimum site requirement for the Research & Business Park land use designation is 200 acres. This relatively large minimum site requirement could have a tendancy to target candidate development sites in outlying areas. However, two Site Designation Criterion incorporated into the proposed General Plan land use designation will ensure that development does not impact agricultural areas. The first requires that lands with the "Orchard and Field Crops" General Plan designation and primary/productive agricultural lands and lands that could cause conflicts with existing agricultural operations be precluded from development. Another Site Designation Criterion requires that Research & Business Park sites be in close proximity to existing communities. Much of the productive agricultural land in Butte County is not in close proximity to existing communities. Environmental review of specific development applications will occur as part of the Master Development Plan process. b) Conflict with existing zoning for agricultural use, or a Williamson Act contract? Refer to discussion in item "a". The degree to which Williamson Rct contracts may affect candidate RBP sites has nat been determined. c) Involve other changes in the existing environment which, due to their location or nature, could result in conversion of Farmland fo non-agricultural use? 6 Initial Study -Research & Business Park GPAlRezoning Effects on agricultural operations are expected to be negligible. Refer to discussion in item "a". Air Quality Where available, the significance criteria established by the applicable air quality management or air pollution control district may be relied upon to make the following determinations. Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant Significant Impact With Impact Mitigation Incor orated a) Conflict with or obstruct implementation of X the applicable air quality plan? b) Violate any air quality standard or contribute X substantially to an existing or projected air quality violation? c) Result in a cumulatively considerable net X increase of any criteria for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? d} Expose sensitive receptors to substantial X pollutant concentrations? e) Create objectionable odors affecting a X substantial number of eo le? Discussion: a) Conflict with or obstruct implementation of the applicable air quality plan? Butte County is located in the central portion of the Northern Sacramento Valley Air Basin and is under the jurisdiction of the Butte County Air Pollution Control District. The County has been classified as being either non-attainment or transitional non- attainment for ozone (state and federal), carbon monoxide (federal), and PM~p (state}. However, air quality has improved aver the last three years, and the Butte County Air Quality Management District (BCAQMD) and Butte County Association of Governments recently submitted a redesignation request to the Environmental Protection Agency to certify Butte County as being in attainment of air quality standards. While the proposed Project will not result in additional residents, it could result in alterations in travel patterns of existing residents from within and outside the county. Inasmuch as one of the primary objectives of the Research & Business Park General Plan and Zoning designations is creation of employment opportunities, it is likely that development of a project will result in localized air emissions associated with commute trips to and from new jobs. In addition, additional emissions could occur as a result of Initial Study -Research & Business Park GPAlRezoning vehicle trips associated with pick-up and delivery of raw materials and finished products. The requirement for preparation of a traffic study at the time of application for Master Development Plan will provide a basis of analysis of potential vehicle trips and associated emissions. A third source of potential air emissions is operation of businesses within the Research & Business Parks. While the RBP land use designation is specifically intended for uses that do not create nuisances, including air emissions, it is possible that certain manufacturing operations could result in emissions that affect local air quality. The Butte County Air Pollution Control District recommends incorporating all feasible mitigation measures to reduce emissions to less-than-significant levels. Mitigation measures should be imposed an a project-by-project basis, as appropriate. The following mitigation measure is recommended: Mitigation Measures: 2. A detailed environmental analysis of specific development applications shall occur as part of the Master Development Plan process. The analysis shall include an estimate of potential mobile and point source air emissions and provide recommendations for reducing emissions to less-than-significant levels. b) Violate any air quality standard or contribute substantially to an existing or projected air quality violation? Refer to item "a", above. c) Result in a cumulatively considerable net increase of any criteria for which the project region is non-attainment under an applicable federal or state ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors) ? The potential for cumulatively considerable impacts will be determined at the time environmental analysis of Master Development Plan applications occurs. d) Expose sensitive receptors to substantial pollutant concentrations? Refer to discussion in items "a" and "c", above. e) Create objectionable odors affecting a substantial number of people? 8 initial Study -Research & Business Park GPA(Rezoning Refer to discussion in items "a" and "c", above. Language in bath the proposed RBP General Plan and Zoning text prohibit uses that will result in nuisance factors on uses within and beyond the Research & Business Park. Biological Resources Would the project: Environmental Issue Potentially Less Than less Than No Impact Significant Significant With Significant Impact Mitigation Impact Ineor orated a) Have a substantial adverse effect, either x directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? b} Have a substantial adverse effect on any x riparian habitat or other sensitive natural community identified in local or regional plans, policies or regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? c) Have a substantial adverse effect on x federally protected wetlands as defined by Section 404 of the Clean Water Act {including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? d) Interfere substantially with the movement of x any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? e) Conflict with any local policies or ordinances x protecting biological resources, such as a tree preservation policy or ordinance? f) Conflict with the provisions of an adopted x Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, re Tonal, or state habitat conservation Ian? Discussion: a) Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate sensitive, or special status species in local or regional plans, policies or regulations, or by the California Department of Fish and Game or U. S. Fish and Wildlife Service? Areas where Research & Business Park development may be proposed may include vernal pools and other environmentally-sensitive habitat. Previous studies have 9 Initial Study -Research & Business Park GPAtRezoning revealed the presence of a number of special-status plant species within the county, including Greene's tuctoria, hairy orcutt, Hooper's spurge, Shippe meadowfoam, and Butte County checkerbloom. Also, some areas of the county may be winter range for the Greater Sandhill Crane, aspecial-status species. However, since areas proposed far development have not been identified at this time, the extent of potential impact cannot be ascertained. Among the Site Designation Criteria contained in the proposed General Plan text is a requirement that sites have minimal impacts on environmentally sensitive lands, such as wetlands, areas with sensitive habitat and steep slopes. Avoidance of sensitive environmental features is also cited as a Zoning Factor in the proposed General Plan text. Inasmuch as the Zoning district suggests that clustering concepts may be used to preserve environmentally sensitive areas, the extent of potential impact on such features may be minimized. Specifically, RBP projects may either avoid such areas entirely or incorporate and preserve them within the project boundary using development clustering techniques. ~Jotwithstanding the above statements, there is a potential for modification of sensitive habitat and adverse impacts on sensitive and special-status species. The presence of such features cannot be assessed at this time, since candidate sites for the Research & Business Park land use designation have not been identified. To aid in identifying and minimizing impacts on sensitive environmental features, the Master Development Plan submittal requirements include a biological assessment. The following mitigation measure is recommended to aid in the environmental analysis: Mitigation Measures: 3. The biological assessment required as part of the Master Development Plan submittal shall be used in the completion of the overall environmental analysis of each Master Development Plan. Special attention shall be given to potential impacts on sensitive and special-status species and on environmentally sensitive areas. b) Have a substantial adverse effect on any riparian habitat or other sensitive natural community identified in local or regional plans, policies or regulafions or by the California Department of Fish and Game or U. S. Fish and Wildlife Service? Refer to discussion in item "a", above. c) Have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the Clean Water Act (including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal, filling, hydrological interruption, or other means? Refer to discussion in item "a", above. la Initial Study -Research & Business Park GPA/Rezoning d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? Refer to discussion in item "a", above. e) Conflict with any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance? Refer to discussion in item "a", above. t) Conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plan, or other approved local, regional, or state habitat conservation plan? Refer to discussion in item "a", above. Cultural Resources Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a) Cause a substantial adverse change in the X significance of a historic resource as defined in Section 15064.5? b) Cause a substantial adverse change in the X significance of an archaeological resource pursuant to Section 15064.5? c) Directly or indirectly destroy a unique X paleontological resource or site or unique geologic feature? d} Disturb any human remains, including those X interred outside of formal cemeteries? Discussion: a) Cause a substantial adverse change in the significance of a historic resource as defined in Section 15064.5? Previously prepared environmental assessments have revealed the presence of significant cultural resources, including historic and prehistoric sites and artifacts, at various locations throughout the county. As such, it is possible that a site selected for ZZ Initial Study -Research & Business Park GPA/Rezoning development as a Research & Business Park could result in the disturbance of such features. As previously noted, candidate sites for the proposed General Plan and Zoning designations have not been identified. Thus, there is presently no means of determining whether resources would be impacted. Detailed on-site surveys could reveal historic and/or prehistoric features. Moreover, site grading activities could reveal archaeological sites and artifacts not discovered during on-site reconnaissance. The following mitigation measures are recommended: Mitigation Measures: 4. In accordance with current County practice, if County archeological sensitivity maps indicate that resources may be present a records search will be conducted as part of the Master Development Plan approval process. The results of the records search will determine the need for an on-site survey. 5. Information contained in the records search shall be incorporated into, and guide, the environmental analysis of specific development applications that shall occur as part of the Master Development Plan process. b) Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 95064.5 Refer to item "a", above c) Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature? Refer to item "a", above d) Disturb any human remains, including those interred outside of formal cemeteries? Refer to item "a", above 12 Initial Study -Research 8~ Business Park GPA/Rezoning Geology and Soils Would the project: Environmental Issue Potentially Less Than less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a) Expose people or structures to potential substantial adverse effects, including the risk of loss, injury, or death involving: i} Rupture of a known earthquake fault, as X delineated on the most recent Alquist-Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other substantial evidence of a known fault? (Refer to Division of Mines and Geology Special Publication 42.) ii) Strong seismic ground shaking? X iii) Seismic-related ground failure, including X liquefaction? iv) Landslides? X b) Result in substantial soil erosion or the loss X of topsoil? c} Be located in a geological unit or soil that is X unstable, or that would become unstable as a result of the project, and potentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? d} Be located on expansive soil, as defined in X Table 18-1-8 of the Uniform Building Code (1994), creating substantial risks to life or property? e) Have soils incapable of adequately X supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water? Discussion: a. i) Rupture of a known earthquake fault, as delineated on the most recenf A/quist- Priolo Earthquake Fault Zoning Map issued by the State Geologist for the area or based on other subsfantial evidence of a known fault? (Refer to Division of Mines and Geology Special Publication 42.) Like all of Butte County, candidate Project sites will be subject to ground shaking to f`U1odified Mercalli VII levels. The most significant mapped fault in the area is the Cleveland Hill Fault. The latest seismic movement on that fault occurred near Oroville in 1975. 13 Initial Study -Research & Business Park GPA/Rezoning While the northern-most edge of Butte County is approximately 50 miles south of Mt. Lassen, a site of historic volcanic activity, there is no record of any portion of Butte County being directly affected by a volcano in historic time. Accordingly, the probability of volcanic activity impacting the Project area is very low. Requirements embodied in the Uniform Building Code address the local seismic setting (Seismic Zane 3), and should provide adequate resistance to possible seismic activity. a.ii) Strong seismic ground shaking? Refer to item "a.i", above. a.iii) Seismic-related ground failure, including liquefaction? The area is considered to have low to moderate liquefaction potential. a.iv) Landslides? Landslides are possible in areas of steep topography, particularly where certain soil conditions are present or where oversaturation from prolonged rainfall has caused instability. While the cost of developing a steeply sloping site as a Research & Business Park would likely be cost prohibitive due to the extensive grading required to create building pads, there is a potential for such construction to occur. Among the Site Designation Criteria in the proposed General Plan text is a requirement that candidate Research & Business Park sites avoid steep slopes, and Master Development Plan submittal requirements contained in the proposed Zoning text require a slope map as part of the application process. While the proposed General Plan text does not define "steep slopes", applications will be required to provide information that sufficiently identifies site topography. b) Resu/t in substantial soil erosion or the loss of topsoil? The potential for soil erosion varies throughout the county. Nonetheless, the proposed RBP land use designation could provide for site development activities that expose large areas to the erosive effects of rain and wind. While grading volumes will be minimized somewhat by the General Plan Site Designation Criterion that requires avoidance of steep slopes, any development project will require surficial (i.e., relatively shallow} soil disturbance for construction of streets, parking areas, and buildings. Among the Master Development Plan submittal requirements is the requirement far submittal of a conceptual grading, erasion control, and drainage plan. This information will assist in determining the need for further erosion control measures. 14 Initial Study -Research & Business Park GPA/Rezoning In the absence of effective erosion control measures, disturbed earth could be carried off-site during periods of heavy rain or high winds. Watercourses and wetlands are particularly vulnerable to siltation impacts. The following mitigation measure is recommended to reduce potential erosion impacts to aless-than-significant level: Mitigation Measures: 6. Construction documents shall require the construction contractor to prepare and implement a Storm Water Pollution Prevention Plan (SWPPP) in conformity with all requirements of the "General Construction Activity Storm Water Permit" adopted by the State Water Resources Control Board on August 20, 1992, and all additions and amendments thereto applicable at the time of construction. Prior to commencement of construction, the developer shall file a Notice of Intention to be covered by the General Permit. Construction documents shall include Best Management Practices (BMPs) to minimize and control the level of storm water runoff and provide a program to ensure that all soil erosion and deposition is contained within the construction site. The Plan shall include specific measures to accomplish erosion control, such as covering slopes with straw or straw matting, vegetating exposed areas following excavation, use of straw bales and filter cloth to prevent off-site filtration, and water for dust control. The General Construction Activity Storm Water Permit process is required because five or more acres of ground surface will be disturbed by grading. c) Be located in a geological unit or soil that is unstable, or that would become unstable as a result of the project, and pofentially result in on- or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? The valley portion of the county may be subject to varying degrees of subsidence as a result of lowering of the groundwater table through domestic and agricultural well use. In past years the groundwater level has been lowered as a result of prolonged drought conditions. d) Be located on expansive soil, as defined in Table 18-7-8 of the Uniform Building Code (1994), creating substantial risks fa life or property? Soils throughout much of the county are considered moderately expansive. This condition is typically mitigated through conventional grading and construction techniques. e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available far the disposal of waste water? 15 Initial Study -Research & Business Park GPA/Rezoning Candidate sites for application of the proposed General Plan and Zoning designations have not been identified. Some, but not all, possible sites may be in close proximity to sanitary sewers, thus negating the need for on-site, or alternative, sewage disposal systems. In all likelihood, most candidate sites will be accessible to an existing sanitary sewer system or will cause the extension of an existing system far the fallowing reasons: Among the Site Designation Criteria contained in the proposed General Plan text are requirements that sites be in close proximity to existing communities and that sites be in close proximity to existing or planned major infrastructure. It should be noted, however, that there is no specific prohibition against an-site systems. Hazards and Hazardous Materials Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a} Create a significant hazard to the public or the X environment through the routine transport, use, or disposal of hazardous materials? b) Create a significant hazard to the public or the X environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? c) Emit hazardous emissions or handle X hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? d} Be located on a site which is included on a list X of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? e) For a project located within an airport land use X plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? f} For a project within the vicinity of a private X airstrip, would the project result in a safety hazard for people residing in the project area? g) Impair implementation of or physically X interfere with an adopted emergency response plan or emergency evacuation plan? h) Expose people or structures to a significant X risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? 16 Initial Study -Research & Business Park GPRJRezoning Discussion: a) Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? The County has a Hazardous Materials Emergency Response Plan, but has no program for regulating hazardous materials. Problems are addressed in response to complaints received. Creation of Research & Business Parks will increase the potential presence of hazardous materials that may be used in certain manufacturing processes. This is in spite of statements in the proposed General Plan text that specify that these parks are intended far uses that will not create environmental nuisances. As previously noted, while the proposed Zoning district text includes a representative listing of permitted uses, specific uses are not known at this time. Therefore, potential hazardous materials issues must be addressed at the time of Master Development Plan application. The following mitigation measure will reduce potential impacts associated with hazardous materials: Mitigation Measures: 7. In conjunction with the environmental assessment performed at the time of Master Development Plan consideration, an assessment of potential hazardous materials that may be transported to and from, stored, created, or used at the site shall be undertaken. b) Create a significant hazard to the public or the environment through reasonably foreseeable upset and accident conditions involving the release of hazardous materials into the environment? Refer to discussion in item "a", above. c) Emit hazardous emissions or handle hazardous or acutely hazardous materials, substances, or waste within one-quarter mile of an existing or proposed school? Refer to discussion in item "a", above. d) Be located on a site which is included on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment? Refer to discussion in item "a". While no candidate Research and Business Park sites have been identified, the potential exists for hazardous materials to be present on future development sites. This potential will be determined through a review of County records. The following mitigation measure is recommended: 17 Initial Study - Research ~ Business Nark GPAtRezoning Mitigation Measures: 8. If County records indicate that hazardous materials may have been used on a site or there is a potential for past uses, a phase one site assessment shall be performed prior to Master Development Plan approval to determine whether hazardous materials exist on a potential development site and to recommend remediation, as necessary. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? All development within proximity of an airport is subject to the Comprehensive Land Use Plan (CLOP) adopted by the County, which specifies land use limitations based on a variety of factors. f) For a project within the vicinity of a private airstrip, would the project result in a safety hazard for people residing in the project area? Residential uses are not permitted in the Research and Business Park zone. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? Public streets are designated as the primary emergency response and evacuation routes in the county. One of the Master Development Plan submittal requirements is preparation of a traffic study. The study will assess the adequacy of existing and proposed roadways to accommodate traffic associated with a proposed Research & Business Park. Traffic study required at the time of Master Development Plan submittal will address emergency response and evacuation. h) Expose people or structures fo a significant risk of toss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? Construction of Research & Business Parks will have the immediate effect of replacing highly flammable non-native annual grassland with buildings, hardscape, and irrigated landscaping. In addition to eliminating fire fuel, such projects will provide fire breaks. The introduction of uses will, however, introduce potential sources of fire and flammable materials. This potential impact will be addressed through specific development standards applied at the time of Master Development Plan consideration. 18 Initial Study -Research & Business Park GPA/Rezoning Hydrology and Water Quality Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a) Violate any water quality standards or waste X discharge requirements? b) Substantially deplete groundwater supplies X or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rate of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? c) Substantially alter the existing drainage X pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? d} Substantially alter the existing drainage X pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? e} Create or contribute runoff water which X would exceed the capacity of exi~fing or planned stormwater drainage systems or provide substantial additional sources of polluted water? f) Qtherwise substantially degrade water X quality? g) Place housing within a 100-year flood X hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? h) Place within a 100-year flood hazard area X structures which would impede or redirect flood flows? i) Expose people or structures to a significant X risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? Inundation b seiche, tsunami, or mudflow? X a) Violate any water quality standards or waste discharge requirements? 19 Initial Study -Research & Business Park GPA/Rezoning Various substances that contribute to degradation of water quality, including chemicals (e.g., motor oil from parking lots, fertilizers and pesticides from turf areas) and suspended solids (primarily silt) can be transported in storrnwater and irrigation runoff. The greatest potential effect may occur during site grading operations. Effective erosion control measures (see Mitigation Measure 6} will mitigate temporary construction- related potential erosion impacts to aless-than-significant level. With implementation of the water quality measures contained in Mitigation Measure 6 {erosion control during construction) violations of water quality or waste discharge requirements are not anticipated. The storm drainage plan must comply with the requirements of the State Water Resources Control Board, General Construction Activity Storm Water Permit, as noted in Mitigation Measure 6. Among submittal requirements of the Zoning district is preparation of a hydrology report. Development will add to the volume and intensity of storm water runoff by increasing the amount of impervious surface area on project sites. Increased runoff will increase the amount of surface water in local watercourses. The hydrology report required at the time of Master Development Plan submittal will address water quality issues. In addition to the mitigation measure noted above, the following additional mitigation measure is recommended: Mitigation Measures: 9. Non-building setbacks of at least 100 feet shall be established from the tap of bank or historical high water mark (whichever is greater) all perennial streams and riparian areas. The non-building setback shall also prohibit grading activities. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level (e.g., the production rafe of pre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? As proposed, Research & Business Park applications must be in close proximity to existing communities and to existing or planned major infrastructure. However, there is no specific prohibition against the use of wells. The following mitigation measure is recommended for any project that proposes wells in order to address potential impacts on groundwater supplies: Mitigation Measures: 10. Where on-site wells are proposed, an analysis shall be prepared by hydrogeologist that describes the water demands of the proposed project and identifies the impact that demand will have on local groundwater supplies 20 Initial Study -Research 8~ Business Park GPA1Rezoning c) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on- or off-site? Refer to discussion in item "a", above. d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, or substantially increase the rate or amount of surface runoff in a manner which would result in flooding on- or off-site? Refer to discussion in item "a", above. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted water? Refer to discussion in item "a", above. As noted, a hydrology study is required to be prepared and submitted with the Master Development Plan application. f) Otherwise substantially degrade water quality? Refer to discussion in items "a" and "e", above. g) Place housing within a 1 DO-~~ear flood hazard area as mapped on a federal Flood Hazard Boundary or Flood Insurance Rate Map or other flood hazard delineation map? No housing is proposed as part of the Research & Business Park land use designation, other than limited stay residential facilities, permitted subject to granting of a conditional use permit. h) Place within a 900-year flood hazard area structures which would impede or redirect flood flows? Avoidance of flood-prone areas is one of the Site Designation Criteria listed in the proposed General Plan text. Accordingly, projects will not be allowed to be constructed within 100-year flood zones, as identified in the required hydrology study and on County maps. i) Expose people or structures to a significant risk of loss, injury or death involving flooding, including flooding as a result of the failure of a levee or dam? Refer to discussion in item "h", above. Water bodies, such as Oroville Lake and Thermalito Forebay and Afterbay, could cause widespread flooding of certain potential 21 Initial Study -Research & Business Park GPA/Rezoning project sites in the event of dam failure. Construction within areas subject to such flooding is subject to review and approval of the State Department of Water Resources. j) Inundation by seiche, Tsunami, or mudflow? Refer to discussion in item "i", above. Land Use and Planning Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a} Physically divide an established community? x b) Conflict with any applicable land use plan, x policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance} adopted for the purpose of avoiding or mitigating an environmental effect? c) Conflict with any applicable habitat x conservation plan or natural community conservation Ian? Discussion: a) Physically divide an established community? Candidate sites have not been identified; therefore, the potential for a RBP project to divide an established community cannot be ascertained. One of the Site Designation Criteria in the proposed General Plan text stipulates that proposed projects must be in close proximity to existing communities while creating or maintaining open space values. While creation of a physical division in a community is unlikely, the potential exists. This issue will be addressed on a project-specific basis as part of the environmental review process. b) Conflict with any applicable land use plan, policy, or regulation of an agency with jurisdiction over the project (including, but not limited to the general plan, specific plan, local coastal program, or zoning ordinance) adopted for the purpose of avoiding or mitigating an environmental effect? The Project provides for amendments to the Butte County General Plan and Zoning Ordinance. As such, where it is applied it will replace the existing General Plan and Zoning designations currently applicable. The proposed General Plan and Zoning designations are intended to provide land use policy and ordinance direction that is internally consistent. 22 Initial Study -Research & Business Park GPA/Rezoning While the proposed Research and Business Park designation include requirements that do not exist in current County General Plan designations and Zoning districts, similar projects could be proposed in existing Zoning districts. c) Conflict with any applicable habitat conservation plan or natural community conservation plan? Provisions of the proposed General Plan and Zoning text preclude development of sites with sensitive environmental features. Mineral Resources Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated aj Result in the loss of availability of a known x mineral resource that would be of value to the region and the residents of the state? b) Result in the loss of availability of a locally- x important mineral resource recovery site delineated on a local general plan, specific Ian or other land use Ian? Discussion: a) Result in the lass of availability of a known mineral resource that would be of value to the region and the residents of the state? The potential presence of important mineral resources that could be affected by development cannot be ascertained because candidate sites have not been selected. This issue will be addressed as part of the environmental assessment performed for individual Research and Business Park development requests. b) Resu/t in the loss of availability of alocally-important mineral resource recovery site delineated on a local genera! plan, specific plan or other land use plan? Refer to discussion in item "a". 23 Initial Study -Research & Business Park GPA/Rezoning Noise Would the project result in: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a} Exposure of persons to or generation of X noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? b} Exposure of persons to or generation of X excessive groundborne vibration or groundborne noise levels? c} A substantial permanent increase in ambient X noise levels in the project vicinity above levels existing without the project? d} A substantial temporary or periodic increase X in ambient noise levels in the project vicinity above levels existing without the project? e} For a project located within an airport land X use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? f) For a project within the vicinity of a private X airstrip, would the project expose people residing or working in the project area to excessive noise levels? Discussion: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Currently, noise levels in most undeveloped areas of the county are relatively low, the loudest of which are generated by traffic on highways and other streets. Noise impacts associated with ultimate development of Research & Business Park projects are both short- and long-term in nature. Short-term impacts will occur as a result of construction activities, including use of earthmoving equipment and power tools. Long-term noise impacts will result from increases in automobile traffic and noise associated with ultimate land uses. The highest potential noise levels are likely to occur during construction activities. For example, heavy earthmoving equipment can be expected to generate noise levels of between 85 to 90 decibels (dBA) at a distance of 50 feet from the source, and chain saws used for tree removal will create noise levels of 95 dBA at a distance of 50 feet. 24 Initial Study -Research 8~ Business Park GPA/Rezoning As stated in the proposed General Plan text, uses in the Research & Business Park land use designation are intended to be compatible with uses within and adjacent to the project and should not create nuisance factors, such as noise. Nonetheless, certain uses could cause noise impacts as a result of traffic and routine operations. All proposed Research and Business Parks are subject to the Noise Element of the County General Plan, which establishes land use compatibility standards applicable at all potential uses. b) Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels? Refer to item "a". c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Refer to item "a" and Mitigation Measure 18. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Refer to item "a" and Mitigation Measure 18. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? The Comprehensive Land Use Plan controls land use near airports. In so doing, noise exposure from airplane overflights is also addressed. ~ For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? There will be no residential development with the Research and Business Park zone. 25 Initial Study -Research & Business Park GPA/Rezoning Population and Housing Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant Significant Impact With Impact Mitigation Incor orated a) Induce substantial population growth in an X area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? b) Displace substantial numbers of existing X housing, necessitating the construction of replacement housing elsewhere? c) Displace substantial numbers of people, X necessitating the construction of replacement housin elsewhere? Discussion: a) Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses) or indirectly (for example, through extension of roads or other infrastructure)? The proposed Research & Business Park designation will create job opportunities; however, no housing is proposed. Development as envisioned in the Research & Business Park concept could require extension of certain infrastructure into an area, particularly roads, and water and sewer trunklines. Sewer and water facility extensions would be required unless the area is to be served by on-site wastewater and water facilities. While the proposed General Plan text suggests that "leap-frog" development and growth inducing impacts will be minimized through the requirement that RBP sites be in close proximity to infrastructure systems and the requirement for proximity to existing communities, projects could create demand for new housing and could be viewed as growth inducing. The potential for growth inducement will be addressed on asite-specific basis at the time Research and Business Park projects are proposed. b) Displace substantial numbers of existing housing, necessitating the construction of replacement housing elsewhere? Development is expected to occur on vacant sites; therefore, there will be no direct displacement of housing. Moreover, indirect displacement as a result of creation of 26 Initial Study -Research & Business t'ark GPAIRezoning incompatible uses is unlikely given the land use controls embodied in the Zoning text which are intended to minimize nuisance factors. c) Displace substantial numbers of people, necessitating the construction of replacement housing elsewhere? Refer to discussion in item "b", above. No aspect of the proposed General Plan and Zoning texts are intended to result in the displacement of people. Public Services Would the project result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities, need for new or physically altered governmental facilities, the construction of which could cause significant environmental impacts, in order to maintain acceptable service ratios, response times or other performance objectives for any of the fallowing public services: Environmental Issue Potentially Significant Impact Less Than Significant With Mitigation Incor orated Less Than Significant Impact No Impact a} Fire protection? X b} Police protection? X c} Schools? X d} Parks? X e Other ublic facilities? X Discussion: a) Fire protection? Fire protection services are provided by the Butte County Fire Department, assisted by California Department of Forestry through an annual contract with the County. Twenty- one stations are staffed around the clock during summer and 17 stations are fully staffed during winter. An existing mutual aid agreement with the City of Chico requires specific requests for assistance an an incident-by-incident basis. No changes in fire protection are proposed as part of this Project; however, creation of Research & Business Parks will add to the work load of the fire department by introducing buildings and property subject to fire damage, by introducing potentially hazardous materials, and by introducing persons who could require emergency response. The requirement for preparation of an infrastructure plan will identify fireflow availability. Appropriate Fire Department standards will be applied on aproject-specific basis at the time of Master Development Plan consideration. 27 Initial Study - Research ~ Business Park GPAlRezoning b) Police protection? Law enforcement is provided by the Butte County Sheriffs Department. Traffic enforcement is provided by the California Highway Patrol in unincorporated areas. In 1995, the Sheriffs Department had 214 sworn and unsworn deputies. It's adopted service ratio goal is one (1) officer per 1000 population. (The statewide average is 1.6 officers per 1000.) As of 1995, the Department achieved a service ratio of 0.96 officers per 1000 population. The primary Sheriffs Department office is in Oroville, with branch offices in Chico and Paradise Pines. The Sheriff has a mutual aid agreement with the City of Chico. No changes in police protection are proposed. However, RBP projects will add to the Sheriffs department and Highway Patrol workload in the following ways: The addition of buildings and equipment will increase the potential for theft and vandalism, and the addition of employees will increase the potential for crimes against persons. Furthermore, the work load of the Highway Patrol will increase as a result of additional vehicles associated with workforce commute and deliveries of goods and materials. Security issues will be addressed on aproject-specific basis at the time of Master Development Plan submittal. Impact fees collected in the development review process will adequately address the cast of providing Sheriffs services to new development. c) Schools? Schools in the county will be affected by proposed development in two ways, as follows: While schools will receive revenue on aper-square-foot basis for all new buildings (Sterling Fees), workers from outside the school district may have the ability to enroll their children in schools in the district in which they are employed, thus impacting schools. The County has determined that Sterling fees, collected at the time of building permit application, will adequately address potential impacts an schools. d) Parks ? Project employees may utilize public parks; therefore an unquantificable impact on park facilities is likely. However, the Research & Business Park concept specifically calls for inclusion of recreational amenities and open space far the benefit and enjoyment of employees. Thus, the potential impact on parks outside the project sites will be reduced by same factor. e) Other public facilities? 28 Initial Study -Research & Business Park GPA/Rezoning Pacific Gas and Electric Company (PG&E) provides electricity and gas service to many areas in the county. Telephone service is provided by Pacific Bell Company, and cable television services are provided by Chambers Cable Company. The extent and capacity of facilities are not known at this time. Furthermore, the adequacy of facilities cannot be ascertained in advance of identification of candidate sites and identification of specific uses. Recreation Environmental Issue Potentially Significant Impact Less Than Significant With Mitigation Incor orated Less Than Significant Impact No Impact a) Would the project increase the use of X existing neighborhood and regional parks or other recreational facilities such that physical deterioration of the facility would occur or be accelerated? b) Does the project include recreational X facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? Discussion: a) Would the project increase the use of existing neighborhood and regional parks or other recreational facilities such that physical deterioration of the facility would occur or be accelerated? Refer to discussion in Public Services, item "d". b) Does the project include recreational facilities or require the construction or expansion of recreational facilities which might have an adverse physical effect on the environment? Refer to discussion in Public Services, item "d". 29 Initial Study -Research 8~ Business Park GPA/Rezoning TransportationiTraffic Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a) Cause an increase in traffic which is X substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume-to-capacity ratio on roads, or congestion at intersections)? b) Exceed, either individually or cumulatively, a X level of service standard established by the county congestion management agency for designated roads and highways? c) Result in a change in air traffic patterns, X including either an increase in traffic levels or a change in location that results in substantial safety risks? d) Substantially increase hazards due to a X design features (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? e) Result in inadequate emergency access? X f} Result in inadequate parking capacity? X g) Conflict with adopted policies, plans, or X programs supporting alternative transportation e. ., bus turnouts, bic cle racks ? Discussion: a) Cause an increase in traffic which is substantial in relation to the existing traf>ic load and capacity of the street system (i. e., result in a substantial increase in either the number of vehicle trips, the volume-to-capacity ratio on roads, or congestion at intersections) ? Research & Business Parks could result in substantial traffic volumes, could severely impact local roadways, and will have a cumulative effect on the regional street system. As previously noted, candidate sites for Research & Business Park land use have not been designated. Moreover, since specific projects have not been proposed, traffic generation associated with particular uses cannot be projected. While one of the Site Designation Criteria in the proposed General Plan calls for designation of sites in close proximity to existinglplanned highways and arterials streets, improvements are expected to include construction of new streets, widening and realignment of existing streets, construction of overcrossings, and installation of 30 Initial Study -Research & Business r'ark GPA/Rezoning traffic controls. The degree to which such improvements may mitigate potential impacts cannot be accurately determined without further site specific analyses. Among the submittal requirements for Master Development Plans contained in the proposed Zoning Ordinance text is preparation and submittal of a Traffic Study, which will address a variety of circulation-related issues. b) Exceed, either individually or cumulatively, a level of service standard established by fhe county cangesfion management agency for designated roads and highways? The potential for a project to exceed a level of service standard cannot be determined at this time. Refer to discussion in item "a", above and Mitigation Measure 25. c) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? Air traffic will not be affected. d) Substantially increase hazards due to a design features (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? Many of the roads in the undeveloped areas of the county are narrow and have design limitations that make them unsuitable for increased traffic and higher speeds. To the extent that proposed Research & Business Parks are intended to minimize disturbance of existing agricultural lands and uses, farming operations are expected to continue in the vicinity of some projects. Accordingly, the presence of farm equipment on streets near projects could create conflicts with project traffic. This potential impact cannot be fully assessed at this time since candidate sites have not been identified. The traffic study required as part of the Master Development Plan process will address this potential impact. e) Result in inadequate emergency access? As previously noted in Mitigation Measure 9, the traffic study required at the time of Master Development Plan submittal will be required to address potential impacts on emergency access and evacuation. f) Result in inadequate parking capacity? RII parking needs are required to be met on each project site, in accordance with provisions of County Zoning Ordinance Section 24-240. 31 Initial Study -Research & Business r'ark GPPJRezoning g) conflict with adopted policies, plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)? It is anticipated that some employees of proposed Research & Business Parks will commute to and from work by means other than automobile. The primary alternative means of transportation include walking, bicycling, and use of public transit (i.e., bus). The Design Guidelines section of the proposed Zoning text requires that Master Development Plans include design guidelines that include pedestrian and bicycle circulation plans and provision far public transit. The Traffic Study required as part of the Master Development Plan process will address pedestrian circulation issues. Utilities and Service Systems Would the project: Environmental Issue Potentially Less Than Less Than No Impact Significant Significant With Significant Impact Mitigation Impact Incor orated a) Exceed wastewater treatment requirements X of the applicable Regional Water Quality Control Board? b) Require or result in the construction of new X water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? c) Require or result in the constructio^. of new X storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? d) Have sufficient water supplies available to X serve the project from existing entitlements and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater X treatment provider which serves the project that it has adequate capacity to serve the project's projected demand in addition of the provider's existing commitments? f) Be served by a landfill with sufficient X permitted capacity to accommodate the project's solid waste disposal needs? g) Comply with federal, state, and local X statutes and re ulations related to solid waste? 32 Initial Study -Research & Business Park GPA/Rezoning QISCUSS1011: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? The County is presently under an abatement order to eliminate nitrate contamination of groundwater in the Chico urban area. In the absence of having candidate sites identified and knowing the wastewater discharge characteristics of RBP uses, it is impossible to assess the potential for RBP projects to exceed wastewater treatment requirements of the Regional Water Quality Control Board. Wastewater conveyance and treatment issues will be addressed by the Infrastructure Plan required as part of the Master Development Plan process. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Among the Site Designation Criteria contained in the proposed General Plan text is the requirement that RBP sites be in close proximity to existing/planned major infrastructure. While infrastructure extensions will be required in many instances, another Site Designation Criterion requires that sites be in close proximity to existing communities. This will have the effect of reducing the length of water and wastewater extensions. However, nothing in the proposed General Plan text would prohibit the use of on-site water and wastewater systems, if deemed appropriate. Among the proposed Master Development Plan submittal requirements is a requirement for preparation of a schematic infrastructure plan showing the size and availability of facilities. As noted above (item "a"'), wastewater conveyance and treatment issues will be addressed by the Infrastructure Plan required as part of the Master Development Plan process. c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? Refer to discussion in items "a" and "b", above. d) Have sufficient water supplies available to serve the project from existing entitlements and resources, or are new or expanded entitlements needed? 33 Initial Study -Research & Business nark GPR1Rezoning Refer to discussion in items "a" and "b", above. e) Result in a determination by the wastewater treatment provider which serves the project that it has adequate capacity fo serve the project's projected demand in addition of the provider's existing commitments? Refer to discussion in items "a" and "b", above. 1J Be served by a landfill with sufficient permitted capacity to accommodate the project's solid waste disposal needs? Refuse is transported by private hauler to the County-owned Neal Road Landfill. The landfill is operated by a private company, under contract with the County. In 1992, it was estimated that the 101-acre site could continue to accept refuse for an additional 15 years. No changes in solid waste generation, pick-up, or disposal are anticipated. However, development of RBP sites could impact the landfill during construction and on a long- term basis. Solid waste disposal will be addressed on aproject-specific basis at the time individual Research and Business Park projects are proposed. g) Comply with federal, state, and local statutes and regulations related to solid waste? P,efer to discussion in item "f' and Mitigation Measure 30, above. Mandatory Findings of Significance Environmental Issue Potentially Potentially Less Than Na Impact Significant Significant Significant Unless Miti ated a) Does the project have the potential to degrade X the quality of the environment, substantially reduce the habitat of a fish or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or restrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? b) Does the project have impacts which are X individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects. the effects of other current projects, and the effects of probable future projects). c) Does the project have environmental effects X which will cause substantial adverse effects on human bein s, either direct) or indirect) ? 34 Initial Study -Research & Business ~ ark GPAIRezoning Discussion: a) Does the project have the potential fo degrade the quality of the environment, substantially reduce the habitat of a ash or wildlife species, cause a fish or wildlife population to drop below self-sustaining levels, threaten to eliminate a plant or animal community, reduce the number or resfrict the range of a rare or endangered plant or animal, or eliminate important examples of the major periods of California history or prehistory? While approval of RBP projects would have the potential to create significant impacts on the environment, mitigation measures included as part of the project will reduce those potential impacts to less-than-significant levels. Rlsa, as previously noted, further environmental analysis will occur on a project-specific basis following identification of candidate sites and submittal of individual RBP project proposals. b) Does the project have impacts which are individually limited, but cumulatively considerable? ("Cumulatively considerable" means that the incremental effects of a project are considerable when viewed in connection with the effects of past projects, the effects of other current projects, and the effects of probable future projects). Cumulatively considerable impacts are possible, but cannot be accurately identified until detailed environmental analysis is performed. Refer to the discussion in item "a", above. c) Does the project have environmental effects which will cause substantial adverse effects on human beings, either directly or indirectly? Refer to discussion in items "a" and "b", above. V. MITIGATION MEASURES AND MONITORING REQUIREMENTS: 1. A detailed environmental analysis which addresses aesthetic aspects of development applications shall occur as part of the Master Development Plan process. 2. A detailed environmental analysis of specific development applications shall occur as part of the Master Development Plan process. The analysis shall include an estimate of potential mobile and point source air emissions and provide recommendations for reducing emissions to less-than-significant levels. 3. The biological assessment required as part of the Master Development Plan submittal shall be used in the comp-etion of the overall environmental analysis of each Master Development Plan. Special attention shall be given to potential impacts on sensitive and special-status species and on environmentally sensitive areas. 35 Initial Study -Research & Business Nark GPAlRezoning 4. In accordance with current County practice, if County archeological sensitivity maps indicate that resources may be present a records search will be conducted as part of the Master Development Plan approval process. The results of the records search will determine the need for an on-site survey. 5. Information contained in the records search shall be incorporated into, and guide, the environmental analysis of specific development applications that shall occur as part of the Master Development Plan process. 6. Construction documents shall require the construction contractor to prepare and implement a Storm Water Pollution Prevention Plan {SWPPP} in conformity with all requirements of the "General Construction Activity Storm Water Permit" adopted by the State Water Resources Control Board on August 20, 1992, and all additions and amendments thereto applicable at the time of construction. Prior to commencement of construction, the developer shall file a Notice of Intention to be covered by the General Permit. Construction documents shall include Best Management Practices {BMPs) to minimize and control the level of storm water runoff and provide a program to ensure that all soil erasion and deposition is contained within the construction site. The Plan shall include specific measures to accomplish erosion control, such as covering slopes with straw or straw matting, vegetating exposed areas following excavation, use of straw bales and filter cloth to prevent off-site filtration, and water for dust control. 7. In conjunction with the environmental assessment performed at the time of Master Development Plan consideration, an assessment of potential hazardous materials that may be transported to and from, stored, created, or used at the site shall be undertaken. 8. If County records indicate that hazardous materials may have been used on a site or there is a potential for past uses, a phase one site assessment shall be performed prior to Master Development Plan approval to determine whether hazardous materials exist on a potential development site and to recommend remediation, as necessary. 9. Non-building setbacks of at least 100 feet shall be established from the top of bank or historical high water mark {whichever is greater) all perennial streams and riparian areas. The non-building setback shall also prohibit grading activities. 10. Where on-site wells are proposed, an analysis shall be prepared by hydrogeologist that describes the water demands of the proposed project and identifies the impact that demand will have on local groundwater supplies 36 Initial Study -Research & Business rk GPA/Rezoning ENVIRONMENTAL REFERENCE MATERIAL 1.
