Applicant/Owner: Ellen Henn B. Staff Contact: Dan Breedon, Senior Planner C. Proiect Name: Henn General Plan Amendment and Rezone D. Proiect Location: 1701 Oroville Dam Boulevard West E. Tvpe of Application(s): General Plan Amendment and Rezone F. Assessor's Parcel Number: 030-200-026 G. Proiect Site Size: Parcel: 4.8 acres, area of GPAlRezone: 3.97 acres H. Current Zoning: R-3 (Residential}; balance of Parcel: C-2 (General Commercial) General Plan Designation: Medium Density Residential; balance of Parcel: Commercial Environmental Setting: The project site is located along Oroville Dam Boulevard in an unincorporated area of Butte County, west of the City of Oroville. There is a city property around the Oroville Municipal Airport, which is located approximately one-half mile west of the project site. The 4.8-acre project site is developed with a 1200-square foot house that is used for leasing rental trucks. The site is relatively flat and vegetation is limited to grasses except for approximately two deciduous trees near the street side of the property. The project site is not located within a 100-year flood zone. The project is located near the Oroville IVtunicipal Airport, within Compatibility Zone "C," which is the second least restrictive airport zone, but is not located within an over flight zone. The project is located within the Oroville Urban Area. K. Surrounding Land Uses: The project site is surrounded by a variety of uses. To the north and northwest, the area is rural residential in character with grazing land and low density residential development on parcels of approximately one to 21 acres in size. To the south across Oroville Dam Boulevard, there are single-family residences on parcels of approximately 0.25 to 0.50 acres. The property directly to the west on Oroville Dam Boulevard is zoned for commercial use but developed with a single family residence. The next property to the west is zoned for residential use, but is developed with an automobile repair shop. To the east, the abutting property is developed with asingle-family residence. Further to the east is a mobile home park. L. Proiect Description: The project applicant is applying for a change in the General Plan designation and zoning of the back portion of the property (3.97 acres in size} to match the General Plan designation and zoning of the street side portion of the property (0.875 acres in size}, The current zoning on the back portion of the property is Medium Density Residential (R-3} and the current General Plan designation is Residential. The proposed zoning is C-2 (General Commercial) and the proposed General Plan designation is Commercial. These changes are being requested to accommodate development of a 67,500 square foot mini-storage facility, to include 503 individual storage units to be developed in 4 phases. This storage space would be leased on a daily, weekly, or monthly basis to individuals for storage of personal property. ^ Butte County Department of Development Services ^ Planning Division ^ Paget ^ Project Name: Henn General Plan Am. .Went and Rezone, File # GPAlRZ 02-02 For the purposes of this environmental review, the impacts of the mini-storage facility for which this General Plan Amendment and Rezoning is necessary are reviewed using existing conditions as the basis for comparison. Environmental impacts of the change in zoning and General Plan designation aze also assessed in the Land Use section of this Initial Study. Since the Rezone and General Plan Amendment requests are tied to a specific project for which a site plan and other develapment application material has been prepared, the Initial Study focuses on the mini-storage facility and associated impacts. Therefore, if the Rezoning and General Plan Amendment is approved, the approval is conditioned on the environmental review contained in this document, which applies to the development of mini-storage facilities as described in this document and the development application material. The proposed Rezone would be specifically limited to the proposed mini-storage facility through a Conditional Zoning Agreement. This agreement would set-forth the conditions and mitigations imposed by the County to ensure that the property is developed in accordance with the proposal. 141. Public Agency Approvals: Butte County Environmental Health Department, Butte County Public Works Department, Butte County Fire Department, Agricultural Commission, Airport Land Use Commission, and Butte County Air Quality Management District. s' ^ Butte County Department of Development Services ^ Planning Division ^ Page 2 ^ Project Name: Henn General Plan A ment and Rezone, File # GPAIRL 02-02 2.0 DETERMINATION [ ] I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. [ /] 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 revisions have been made by or agreed to by the project proponent. A MITIGATED NEGATNE DECLARATION will be prepared. [ ] I find that the proposed project COULD have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required.

An ENVIRONMENTAL IlvIPACT 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 adequately in an earlier EIR or NEGATNE 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 thg pro osed project, nothing fiuther is required. ~1 Prepare y: Daniel C.

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" or "Less than Significant with Mitigation Measures Incorporated," as indicated by the checklist on the following pages. [X] 4.1 Aesthetics [ ] 4.2 Agriculture Resources [X] 4.3 Air Quality [ ] 4.4 Biological Resources [ ] 4.5 Cultural Resources [X] 4.6 Geologic Processes [ ] 4.7 Hazards,ZIazardous Material [X] 4.8 Hydrology/Water Quality [X] 4.9 Land Use [ ] 4.10 Mineral Resources [X] 4.11 Noise [ ] 4.12 Housing [X] 4.13 Public Services [ ] 4.14 Recreation [X] 4.15 Transportation/Traffic [X] 4.16 Utilities/Service Systems [X] 4.17 Mandatory Findings of Significance B. Evaluation of Environmental Impacts: 1) A brief explanation is required far 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 tb°projects tike 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 factors as well as general standards, {e.g., the project will not expose sensitive receptors to pollutants based on aproject-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} Once the lead agency has determined that a particulaz physical impact may occur, then the checklist answers must indicate whether the impact is potentially significant, less than significant with mitigation, or less than significant. "Potentially Significant Impact" is appropriate if there is substantial evidence that an effect may be significant. If there are one or more "Potentially Significant Impact" entries when the determination is made, an EIR is required. 4} "Negative Declaration: Less Than Significant With 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 Analyses," may be cross-referenced). 5) "Reviewed Under Previous Document." Earlier analyses may be used where, pursuant to the tiering, program EIR, or other CEQA process, an effect has been adequately analyzed in an earlier EIR or negative declaration. Section 15063 (c)(3)(D}. In this case, a brief discussion should identify the following: a} Earlier Analysis Used: Identify and state where they are available for review. b) Impacts Adequately Addressed: Identify which effects from the above checklist were within the scope of and adequately analyzed in an earlier document pursuant to applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. ^ Butte County Department of Development Services ^ Planning Division ^ Page 4 ^ Project Name: Henn General Ptan An~ gent and Rezone, File # GPAlRZ 02-02 c} Mitigation Measures: For effects that are "Less 'T'han Significant with Mitigation Measures Incorporated," describe the mitigation measures which were incorporated or refined from the earlier document and the extent to which they address site-specific conditions for the project. 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. 7) Supporting Information Sources: A source list should be attached, and other sources used or individuals contacted should be cited in the discussion. 8} The explanation of each issue should identify: a} The significance criteria or threshold, if any, used to evaluate each question; and b) The mitigation measure identified, if any, to reduce the impact to less than significant. e ^ Butte County Department of Development Services ^ Planning Division ^ Page 5 ^ Project Name: Henn General Plan Ar. .gent and Rezone, File # GP a1RZ 02-02 4.0 EIV'VIRONiVIENTAL IMPACTS: 4.1 AESTHETICJVISUAL RESOURCES: Potentially Less Than Less Than No Reviewed Would the proposal: Significant Significant Significant impact Under Impact with Impact Previous Mitigation Document Incorporated a. Have a substantial adverse effect on a scenic vista? X b. Substantially damage scenic resources, including, but not limited ta, trees, rock outcroppings, and historic X buildin s within a state scenic hi hwa ? c. Substantially degrade the existing visual character or X uali of the site and its surroundin s? d. Create a new source of substantial light or glare which would adversely affect day or nighttime views X in the area? Impact Discussion: The project would result in the addition of b7,500 square feet of mini-storage space, with one-story buildings throughout the Fear portion, or northern end of the project site. The Rezoning from R-3 to C-2 changes the allowable uses on the site, and thus the future potential aesthetic character of the property and surrounding area. The character of the area as it exists is somewhat diverse. Mobile homes, auto repair, very-low-density and low-density residential development, and grazing land surround the site. The introduction of several thousand square feet of storage buildings on the northern portion of the project property that is currently undeveloped will significantly change the visual character of the site and surrounding area. Medium-density residential development and other similar uses are allowed under the current zoning and General Plan designation. Apartment buildings, group Names, and other development is currently allowed, but the change in zoning would allow commercial uses, which may have different visual characteristics compared to the residential development currently allowed. Design considerations included in Mitigation Measure #1 will ensure visual impacts of the land use change and storage facility are reduced to aless-than-significant level. Tlie project would introduce new sources of light to the extent that security lighting is used around the storage structures. Mitigation pleasure #2 will ensure that the light and glare impacts associated with the operation of the storage facility are reduced to aless-than-significant level. Site landscaping is a requirement of Butte County Code Section 24-240.10, which requires that 5 percent of the gross lot area be devoted to landscaping. Each planter area is required to be surrounded with asix-inch raised concrete curb or equivalent. An irrigation system would also be required. The applicant has disclosed plans to develop a muu-storage facility. The landscaping requirement shall be placed as a condition on the Conditional Zoning Agreement for the mini-storage project and is also set forth below as a mitigation measure for the projects impact on aesthetics of the area. Signage for the business has the potential to impact the aesthetics of the surrounding area. For this reason, signage would be limited to a total of two signs, including one ground, pole or monument style sign and one building sign, not to exceed 500 square feet in total display area. These requirements have been set-forth below as a mitigation measure. ^ Butte County Department of Development Services ^ Planning Division ^ Page 6 ^ ~~ Project Name: Fenn General Plan Arr lent and Rezone, File # GPA/RZ 02-02 Mitigation Measure # l: The mini-storage facility shall be reviewed to ensure that the design and layout of the facility does not result in significant negative aesthetic impact on surrounding properties. The following measures shall be followed in all design aspects of the development: {a) The mini-storage buildings shall be developed in accordance with the plans and renderings provided to, and approved by, the Planning Division. (b} Building shall mimic the materials, colors, themes, size, and scale of surrounding buildings and the surrounding environment. (c) Building materials, colors, design, and finishing system shall be consistent throughout the facility and in accessory buildings. (d) The materials used for buildings, roofs, fences and other structures shall be comparable to those used for surrounding residential uses. (e} The building height shall be no greater than 15 feet. (f} The surfaces of the storage facility that face public roads or residential uses shall receive particular attention in their design to ensure compatibility and appropriateness. (g} The primary entrance to the sales office shall be clearly identifiable. It may be recessed or framed by a sheltering element such as an awning, arcade or portico. (h) All m~'hanical equipment {ventilation systems, HVAC units, AC units, etc.) shall be screened by roofs, fences, or by other means so that it is not visible from public roads or by users of adjacent properties. (i) In order to provide a visual screen and visual relief of long interrupted building facades that are typical of storage facilities, the applicant shall provide a solid screen around the perimeter of the facility using a combination of solid rock wall and landscaping, including a minimum of one 15-gallon tree every 30 feet (this requirement may be used in conjunction with other landscaping treatments to meet the landscaping requirement}. {j) Paint or other surface applications shall be non-glare and non-reflective. {k) Signage shall be limited to one (1) pole, ground or monument sign, and one (1) building sign not to exceed 500 square feet in combined display area (including both sides). Signage shall only advertise on-site services and shall not exceed 15 feet in height. Signs may be internally illuminated or illuminated through the use of directional lighting but shall not be flashing or otherwise animated. No banners, streamers, balloons, floodlights, flags, window displays, fence signage, or other advertising display shall be permitted. Any sign that is painted on the wall of the structure shall count towards the 500 square feet of total allowed display area. No sign shall be allowed to be painted on the roof of any structure. The entryway sign shall include landscaping (this requirement may be used in conjunction with other landscaping treatments to meet the landscaping requirement). (1) Five (5} percent of the developed area (approximately 8,700 square feet) shall be devoted to landscaping. Each planter area shall be surrounded with asix-inch raised concrete curb. An irrigation system shall be installed in each separate planter area. Perimeter landscaping and signage landscaping may be counted towards this requirement as discussed in items (i) and (k) above. Plan Requirements: All requirements shall be included on a Conditional Zoning Agreement between the County and landowner. Building plans shall show all applicable requirements. Timing: Requirements of the condition shall be adhered to throughout all grading, construction and operations. ^ Butte County Department of Development Services ^ Planning Division ^ Page 7 ^ ~ r-~ Project tiame: Henn General Plan Am gent and Rezone, File # GPAJRZ 02-02 iLlonitoring: The Planning Division shall review all plans for conformance. Site reviews shall occur on an as- needed basis. Mitit=_ation pleasure # 2: All lighting, exterior and interior, shall be designed and located so as to confine direct lighting to the premises. A light source shall not shine upon or illuminate directly on any surface other than the area required to be lighted. No lighting shall be of the type or in a location such that it constitutes a hazard to vehicular traffic, either on private property or on abutting streets. Plan Requirements: All requirements shall be shown on building plans. Timing: Requirements of the condition shall be adhered to throughout the construction and operation of the project. Monitoring: The Planning Division shall review proposed building and site design for visual impacts and approve the plans. Building inspectors shall spot check and shall ensure compliance on-site. 4.2 AGRICULTURE RESOURCES; Potentially Less Than Less Than No Reviewed Would the proposal: Significant Significant Significant Impact Under Impact with Impact Previous Mitigation Document Incorporated a. Convert Prime Farmland, Unique Farmland, or Farmland of Statewide Importance (Farmland), as shown on the maps prepared pursuant to the X Farmland Mapping and Monitoring Program of the California Resources Agency, to non-agricultural use? b. Conflict with existing zoning for agricultural use, or X a Williamson Act Contract? c. Involve other changes in the existing environment which, due to their location or nature, could result in X conversion of Farmland, to non-agricultural use? Impact Discussion: The northern portion of the project site is currently designated Medium Density Residential in the Butte County General Plan.

Impact Discussion: o' Both the California Air Resources Board and the Environmental Protection Agency have established air pollution standards in an effort to protect human health and welfare. Geographic areas are designated "attainment" if these standards are met and "nonattainment" if they are not met. In addition, each agency has several levels of classifications based on severity of the problem. Butte County and all northern Sacramento Valley Air Districts have been designated as "moderate" nonattainment areas for the state standards for ozone and fine particulate matter (PM10). Currently, Butte County is in attainment for all the federal (less stringent) air quality standards. Vehicular traffic generated by the project site would result in a cumulative impact on air quality created by the increase in vehicle traffic (and associated exhaust emissions) and dust from vehicular traffic on any unpaved driveways that maybe used during construction. Tlie project may create fugitive dust emission during site development activities, such as grading, excavation for foundations and utilities, road construction, and other soil wank. The Butte County Air Quality Management District (BCAQMD) recommends incorporating measures to control fugitive dust emission for all road and other construction activities during project development, using such methods as site and driveway watering and/or use of other acceptable soil palliatives. Mitigation Measure.#3 is required, which a note be placed on the final map stating that dust control measures shall be taken during site development activities. The Butte County portion of the NSVAB is designated non-attainment for particulate matter (State standards), and ozone {State and federal standards). The Butte County Air Quality Management District (BCAQMD) is responsible for administration of air quality standards. ^ Butte County Department of Development Services ^ Planning Division ^ Page 9 ^ Project Name: Henn General Plan Ar. ,,ent and Rezone, File # GPNRL 02-02 Short-term Construction Impacts. Use of gasoline- or diesel-powered equipment will be required for grading, trenching, roadwork, and other activities necessary for the implementation of the proposed Project. Earthwork will be required for the installation of lighting, utility work, roadwork, storm water and sewer improvements, and other improvements. The Project may cause short-term impacts during site preparation and construction as a result of equipment exhaust emissions and dust. Dust emissions from construction will vary from day to day, depending on the amount and direction of wind, other climatologically factors, and the level and type of on and off site construction-related activity. Construction vehicle emissions of ozone, ozone precursors, and PM10 will minimally contribute to local violations of ozone {Q3} and particulate matter standazds.l Using project information contained in development application materials, including phasing plans, pollutant emissions associated with construction activities have been estimated. The air quality analysis software, URBEMIS7G, is used for review of project impacts under CEQA, and was used to estimate the level of air pollution associated with the Project. The estimated level of criteria pollutants associated with the Project, according to URBEMIS, are below the Butte County Air Quality Management District (BQAQMD) significance thresholds when the project is phased so that no more than 20,000 square feet of building space is under construction at once {see Appendix A). The thresholds of significance have been established by the BCAQMD to implement air quality attainment plans for the azea. These thresholds are summarized below in Table 1. Because the level of pollution associated with this Project will not exceed Butte County Air Quality Management thresholds with phasing limitations, and because the impacts of the Project will be temporary, the impact is less than significant. Nonetheless, consideration of feasible mitigation measures, which are specified below, is a requirement under CEQA. Mitigation measures specified below require that the project be phased so that a maximum of 20,000 square feet of building space is under construction at once. 0~ 1 PMifl refers to particle matter {PM) less than 10 microns in aerodynamic diameter. ^ Butte County Department of Development Services ^ Planning Division ^ Page 10 ^ ~ O Project Name: ltenn Gene; al Plan A: ~~ent and Rezone, File # GP,4/RZ 02-02 Table 1: BCAQM©Thresholds and Required Actions TABi_E 1: ACTION-LEVEL THRESHOLDS Level A Thresholds Non ROG I PM10 j ZS Ibs/day or lcss 25 tbslday ar Icss ~ 801bslday oar lt~ Level B Thresholds NOx ROG PM10 ~Greatt:, than 25 lbs/day Greater than 25 lbs/day ~ Greater than 801bs/day Level C Thresholds NOz ROG PM10 Greater than 137 lbslday ~ Greater than 137 Ibs/day Greattr than 137 Ibs/dav Level A: Indirect sources which have the potential m emit Icss than 25 pounds pa day bf ROG or Nott, a less than 80 pounds pa dry of PM10 (n calculated by the District}, would be subject m the recommended tut of standard mitigatim measure unless acempted in writing by the applicable planning agcnry {Sec Sation Vl, Mitigation Mansard).

The impacts of construction outlined in the paragraphs above and mitigated by Mitigation Measure #3 do not include the impact on air quality of the Project once it is operational. The difference between existing conditions and the conditions after the Project are mostly the result of altered traffic patterns in and around the Project Area. Other assumptions about use of heating and cooling equipment, aerosol sprays, and other non- traffic related sources of air pollution are also included in the analysis. The trip rates used to estimate traffic-related operational air quality impacts are based on assumptions within the URBEMIS?G air quality analysis software for warehouse uses. Operational impacts of the project are expected to be below BCAQMD thresholds, according to URBEMIS (see Appendix A). Mitigation Measure #3: Place a note on a separate document which is to be recorded concurrently with the map or on an additional map sheet that states: "Dust generated by the development activities shall be kept to a minimum with a goal of retaining dust on the site. Follow the dust control measures listed below: (a) During clearing, grading, earth moving, excavation, or transportation of cut or fill materials, water trucks or sprinkler systems are to be used to prevent dust from leaving the site and to create a crust after each day's activities cease. (b} During construction, water trucks or sprinkler systems shall be used to keep all areas of vehicle movement damp enough to prevent dust from leaving the site. At a minimum, this would include wetting down such areas in the later morning and after work is completed for the day and whenever wind exceeds 15 miles per hour. ^ Butte County Department of Development Services ^ Planning Division ^ Page 11 ^ Project Name: Henn General Plan An .,ent and Rezone, File # GPAJRZ 02-02 (c) Sail stockpiled far more than two days shall be covered, kept moist, or treated with soil binders to prevent dust generation."

No riparian vegetation is located on the site and the site does not contain any wetlands (Oroville General Plan ElR). Ruddy Creek is located approximately 800 feet to the east of the proposed project site and the Oroville Wildlife Area is located approximately 0.5 miles to the southeast of the project site. The impacts of the Rezoning and General Plan Amendment on these resource areas is expected to be less than significant because the project would not generate discharge or other pollution that could potentially influence these areas and because of the distance to the resource areas. The land between the project site and the aforementioned resources areas is developed with residential and commercial uses. Animals that may be found on the project site include rabbits, squirrels, skunk, raccoons, opossum, and various species of birds. Based on information provided in the Butte County General Plan and Master Environmental Assessment, it is not likely that rare ar endangered animal species would be found on the project site. Construction activities and the residential use on the project site would cause some of the animals currently utilizing the project site to move to new areas. This is not expected to be significant because the project site with sparse vegetation and lack of surface water would not support a large number of animals and the animals typically found in this type of residential agricultural setting are not rare or endangered. This project would not have a significant impact to fish or wildlife habitat and the collection of Department of Fish and Game fees pursuant to Fish and Game Code Section 711.4(d}(3) and 14 CCR 753.5 are not required. The project would not conflict with any local policies or ordinances protecting biological resources. The proposal would not conflict with the provisions of an adopted Habitat Conservation Plan, Natural Community Conservation Plat, or other approved local, regional, or state habitat conservation plan.

Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal X system where sewers are not available for the disposal ar waste water? Impact Discussion: The Seismic Safety Element of the Butte County General Plan uidicates that all of Butte County is in Moderate Earthquake Intensity Zone VIII. The site is not within an Alquist-Priolo Earthquake fault zone or an aftershock zone. The nearest active fault is the Cleveland Hill Fault, located approximately 15 miles east of the project site. The Butte County GIS Fault Lines theme shows that an inferred fault is located approximately 2.5 miles to the east of the site. This inferred fault is a part of the Foothill Shear Zone and has not experienced any known movement during historical times. No impacts are anticipated since no rupture of a known earthquake fault exists in the project area. The intensity of ground shaking at any specific site depends on the characteristics of the earthquake, the distance from the earthquake, and on the local geologic soils and conditions. At present, there is insufficient data to predict accurately the expected ground motions at various locations in Butte County. However, strong seismic ground shaking is closely related to the proximity of active fault lines. Although there is insufficient data to predict these forces, the closest mapped Fault-Rupture Zone is the Cleveland Hills fault zone, which is located approximately 15 miles to the east of the project site. The Cleveland Hills fault line is the only fault line in Butte County that is recognized under the Alquist-Priolo Special Study Zones Act to pose a threat from fault rupture. However, new strucritres placed on the site are required to meet the seismic standards of the Uniform Building Code. ^ Butte County Department of Development Services ^ Planning Division ^ Page 15 ^ Project Name: Henn General Plan Am ,.gent and Rezone, File # GPAIRZ 02-02 Seismic risk is not limited to faults which have been currently identified. Some earthquakes originate from unknown sources sometimes characterized as "background seismicity" or "floating earthquakes". The Butte County Master Environmental Assessment indicates that it is reasonable to assume that background seismicity could produce earthquakes as large as Richter magnitude (modified Mercalli intensity scale) b.5 virtually anywhere in Butte County. There is na current evidence that an earthquake larger than magnitude 6.5 could occur at this location. Earthquakes at this magnitude are generally felt by all persons, but damage is generally slight to minor, with fallen chimneys and cracked plaster the most prominent damage. Richter magnitude 6.5 is not subjectively characterized on the intensity scale, but a magnitude 7.0 is generally characterized by negligible damage, especially in buildings of good design and construction. Considerable damage could occur in poorly built or badly designed structures. However, the impact would be less than significant. The Butte County Seismic Safety Element's Liquefaction Potential Map indicates that the site has a low potential for liquefaction. The impact would be less than significant. The Subsidence and Landslide Potential Map of the Safety Element of the Butte County General Plan indicates that there is no to low potential for landslides in this area. Due to the lack of steep slopes on the project site, no impact is anticipated. The project site is also not located in an area with potential for subsidence, according to this map. The Erosion Potential Map of the Safety Element of the Butte County General Plan indicates that the soil erosion potential for the project site is moderate. The site is relatively flat. Standard construction techniques are required as part of the construction process of this site, which would help prevent significant soil erosion impacts. Disruption of soils on the site is not expected to create significant soil erosion due to the level nature of the site and due to the maderate potential for soil erosion. Mitigation Measure #3, included in the Air Quality section of this Initial Study will reduce erosion from wind. No impact is anticipated from instability, landslide, lateral spreading, subsidence, liquefaction, or collapse. The Conservation Element's Expansive Sails Map indicates that the project site has a high expansive soil potential. The Building Division may require that the foundations of future dwelling on the site be designed and constructed to handle the shrink/swell characteristics of expansive soils. No septic systems are proposed. lYlitigation Measure: None required ^ Butte County Department of Development Services ^ Planning Division ^ Page 16 ^ Project :Name f{enn General Plan :fin gent and Rezone, File # GPAIRZ 02-02 ~. 7 HA"LARDS AND HAZARDOUS MATERIALS: Potentially Less Than Less Thao No Reviewed Would the proposal: Significant Significant Significant Impact Under Impact with Impact Previous Mitigation Document Incorporated a.

Impact Discussion: The project site is not located on or near any sources of hazazdous materials and mini-storage uses aze not known to produce or require the use of substances that are particulazly harmful to the environment. Gasoline and diesel fuel will be used in vehicles on-site. These fuels will be used in small amounts, and are not expected to cause significant harm to the environment. The property is located approximately 4,000 feet from the closest runway at the Oroville Municipal Airport. The mitigation measure required as part of the section of this environmental review dealing with aesthetics requires that the buildings be less than 35 feet in height. The project is not located within an over flight area and the height of buildings expected on site would not create a hazardous situation regarding aircraft operations. According to the 2000 Butte County Airport Land Use Compatibility Plan, Zone "C" has restrictions on use and on building and other structures' height. Children's schools, day care centers, libraries, hospitals, nursing homes, and hazards to flight aze prohibited in Zone "C." Hazards to flight include tall structures, structures that would interfere with navigation equipment, and land uses that attract birds. The proposed project does nat conflict with these restrictions. ^ Butte County Department of Development Services ^ Planning Division ^ Page 1? ^ ~ ~""7 Project Name: Henn General Plan Ames .nt and Rezone, File # GPA/RZ 02-42 The project site is not listed on the mast recent Hazardous Waste and Substances Sites List, otherwise known as the CORTESE list.

No impact is anticipated. The project is not located within a State Response Area for wildland and is in an area with an unclassified fire hazard designation, indicating it is either in an urbanized azea or irrigated azea. The project would not expose people or structures to wildland fires because the project area is mostly urbanized. The Butte County Fire Department and California Department of Forestry typically require that the project accommodate access for fire trucks and that the buildings be designed to reduce the risk to fire.

This project would ultimately result in the creation of new impervious surfaces such as roads, buildings, accessory structures, and driveways. This will increase the amount of runoff and pollutant concentrations in the runoff. i/iitigation pleasure #6 will reduce the potential runoff impact to ales-than-significant level. The project site is not located within a 100-year flood zone as shown on the Butte County Department of Development Services GIS information, which is based on recent Federal Emergency Management Agency maps. The property is not located in an area prone to seiche, tsunami, or mudflow, since it is located in the northern Sacramento Valley. No impact would occur with respect to these natural hazards.. ^ Butte County Department of Development Services ^ Planning Division ^ Page 19 ^ Project Name: Henn General Plan Ai went and Rezone, File # GPAtRZ 02-02 Some off-site storm water drainage improvements may be required due to development of the project site. These improvements will be specified in the storm water management plan required by the Regional Water Quality Control Board (referenced in the Hydrology section of this Initial Study) and by the Drainage Plan required by the Public Works Department. These requirements have been set-forth below as mitigation measures. Mitigation Measure #5: The 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 Pemut" 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 project applicant shall file a Notice of Intention to be covered by the General Permit, the contractor shall submit a Storm Water Pollution Prevention Pian, and any necessary clarifications or interpretations shall be obtained from the Central Valley Regional Water Quality Control Board. The construction documents shall include a copy of the General Permit and applicable regulations regarding Storm Water Pollution Prevention Plans. At a minimum, the SWPPP 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 erasion 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. A Storm Water Pollution Prevention Plan and Central Valley Regional Water Quality Control Board involvement are required because the surface area affected by proposed site grading is expected to exceed five acres. Plan requirements: The storm water management measures shall be included in all site and building plans. 0 Timing: The measures shall be implemented during all grading and construction periods, and all required maintenance of storm water management facilities shall be performed during the operational phase of the project, as required. Monitoring: The Planning Division shall review project site and building plans far compliance with specifications of the SWPPP. Building inspectors shall verify on-site during the construction phase and periodically during project operation, as appropriate. l~litigation Measure #ti: Prior to site development and building pernut issuance, a permanent solution for drainage shall be submitted to and approved by the Department of Public Works. The drainage plans shall specify how drainage waters shall be detained on site and or conveyed to the nearest natural or publicly maintained drainage channel or facility and shall provide that there shall be no increase in the peak runoff flow to said channel or facility. Plan Requirements: The mitigation shall be placed on the Conditional Zoning Agreement and shown on all building plans. Timing: The drainage plan shall be required prior to the issuance of building permits. Monitoring: The Department of Public Works shall be responsible for ensuring compliance with this mitigation. ^ Butte County Department of Development Services ^ Planning Division ^ Page 20 ^ ~-7 Project dame: f Tenn General Plan An gent and Rezone, File # GP:VRZ 02-02 4.9 LA.tiv USE: Potentially Less Than Less Than No Reviewed Would the proposal: Significant Significant Significant impact Uuder Impact with Impact Previous Mitigation Document Incorporated a.

Conflict with any applicable habitat conservation X lan or natural communi conservation lan? Impact Discussion: The proposal would amend the General Plan designation and Rezone the northern 3.97 acres of the 4.77-acre site in accordance. Generally, the current Residential {R-3) zoning allows medium density residential development and the proposed General Commti'rcial {C-2) zone allows general commercial and retail activity. Uses allowed in each zone are summarized in Table 3, along with the zones consistent with each of the General Plan designations. This project is proposed in apartially-developed residential and rural residential community north of Oraville Dam Road in an unincorporated portion of Butte County. The northem portion of the property proposed for Rezoning abuts properties designated for residential use. The southern portion of the site fronting Oroville Dam Road is designated far commercial use, as are some properties south of Oroville Road, further to the east. Much of the property along Oroville Dam Road west of Highway 70 is designated for commercial use (see Figure 1 below). The project is located approximately one-half mile east of the Oroville Municipal Airport. The land use change is to accommodate the development of mini-storage facilities, and normally any commercial use may be established on the property consistent with the designated zoning of the property. However, the uses within this project area would be restricted to the proposed mini-storage use through the use of a Conditional Zoning Agreement. The establishment of a more intense commercial establishment such as a 70,000-square foot retail facility or similarly intense use would create significant impacts on the surrounding established residential community. If mini-storage facilities are not developed on the project property following the land use change (should such action be approved} in accordance with the Conditional Zoning Agreement, alternative uses shall be subject to a rezone process and subsequent environmental review in accordance with CEQA. 'hhe City of Oroville commented that the project is within the Oroville Sphere of Influence, and relatively close to existing City limits. The City states that Oroville's General Plan and pre-zoning designate the back portion of the site as Medium Density Residential (maximum 4 dwelling unitslacre) and Single Family Residential (R-1). The City also notes that, except for the Oro Dam Boulevard frontage, all undeveloped land azound the site is designated for single family homes. In addition, the City notes that an extensive area of vacant land zoned for manufacturing-type uses is akeady available on the west side of 18a' Street {within the Oroville City limits). Moreover, the City made recommendations regarding City standards and design provisions to address compatibility. In order to reduce the potential land use conflict impacts to ales-than-significant level, the project must be designed to be physically and functionally compatible with the surrounding residential character. Despite the fact that much of the property along Oroville Boulevard is developed with commercial uses or designated for commercial development, the properties surrounding the northem portion of the project site, where the land use change is proposed, aze residential. ^ Butte County Department of Development Services ^ Planning Division ^ Page 21 ^ ~'j `~ Projctit Name: Nrnn General Plan Ame, ,ent and Rezone, File # GP~~`RZ 02-02 Mitigation Measure #l, included in the Aesthetics portion of this Initial Study, and Mitigation Measure #7, included below reduce potential land use impacts to ales-than-significant level and also address the concerns raised by the City of Oroville. The property is not within a habitat conservation plan or natural community conservation plan. No impact would be incurred. i~Iiti~ation Measure #7: The following mitigation measures are required to reduce the potential impacts on nearby residential areas and impacts resulting from the change in zoning. The mitigation measures are designed to nunimize land use conflicts, but have mitigating impacts in other areas, such as hazardous materials and transportation. The mitigation measures will be referenced; if appropriate, in those other sections but will not be duplicated. The facility may be approved if the following conditions are met: (a} hours of operation shall be lirnited to the hours of 8:00 A.M. to 7:00 P.iv1.

Impact Discussion: The proposed project would not use or extract any mineral or energy resources and would not restrict access to known mineral resource areas. The project is located within an area where there are little or no mineral resources. There are no mining activities within one mile of the project site. Therefore, the project would have no impact on mineral resources.

For a project within the vicinity of a private airstrip, would the project expose people residing or working X in the roject area to excessive noise levels? Impact Discussion: "I~he project site is subject to noise originating from vehicles on Choville Dam Road abutting the project site to the south. Additional noise is generated by the surrounding residential and commercial uses. According to 2000 Traffic Counts for the appropriate section of C)roville Dam Road (State Route 162), the average daily traffic is approximately 7,000 trips. The increase in traffic is estimated using the sixth edition of the Institute of Traffic Engineers Trip Generation manual, which projects an average of approximately 159 trips per day associated with the 67,500-square foot warehouse facility. 2 Using software based on methods of Federal Highway Administration "Highway Traffic Noise Model", FHWA-RD-77-108, the existing noise level, and noise level following implementation of the project is presented below and in Appendix B. As shown below in Table 4, the addition of traffic associated with the project will not appreciably change the noise environment in the project area. A change in noise level of less than one decibel, as is estimated for this project, is not typically considered to be perceptible. The 70 CNEL noise contour would be moved four feet further from the centerline of the road if motor vehicles are moving at 50 miles per hour. The 70 CNEL noise contour would be moved three feet further from the centerline of the road if vehicles are moving at 4~ miles per hour. The other contaur movements would be two feet or less. ~ This represents the total trips generated during a weekday. There are fewer trips generated on weekend days. ^ Butte County Department of Development Services ^ Planning Division ^ Page 24 ^ ~-7 Project Name: Henn General Plan Ar Went and Rezone, File # GPA/RZ 02-02 Table 4 Noise Levels in Pro'ect Area, Existin and with the Im lementatian of the Pro osed Pro ect 45 miles r hour 50 miles er hour Noise Distance Distance Distance Noise Distance Distance ~ Distance Level at to 60 to 65 to 70 Level at to 60 to 65 to 70 49 feet CNEL CNEL CNEL 49 feet CNEL CNEL CNEL ~n Ldn Existin 67 232 111 58 67.8 260 124 63 With 67.1 235 113 59 67.9 264 126 64 Pro'ect Notes: • All distances are in feet. • Speeds aze worst-case scenario for the road near the project azea. • Traffic levels are based on Caltrans traffic counts for 2000, which have not increased since 1998 for the project area. • Percentage truck traffic is also based on the latest traffic counts available from Caltrans, with the assumption that all the truck traffic was heavy traffic (worst-case scenario). • CNEL is an abbreviation for Community Noise Equivalent Level, which is a variation on the decibel scale that gives extra weight to noise generated in the evening and nighttime to reflect additional sensitivity to noise at these times of day. • 49 feet was chosen for the noise level measurement because with the width of the roadway near the project and the required setbacks, a residential structure along Oroville Dam Road would be, at a minimum, 49 feet from the centerline. Construction activities an the site would temporarily generate high noise levels on and adjacent to the project site intermittently during project development activities. During construction, the highest noise levels will result from operation of heavy earthmoving equipment, which can be expected to generate noise levels of between 85 to 90 decibels (dBA) at a distance of 50 feet from the source. Noise levels will be reduced, however, by a factor of six dBA with each doubling of distance from the noise source and by intervening topography. The General Plan Noise Element addresses a maximum acceptable community noise level of 65dBA for low density and multi-family residential land uses to provide a suitable noise environment. Any such noise disturbance would be intermittent and short-terns in nature, but would be significant without the implementation of construction noise attenuation measures, specified below. Additional noise is attributable to the nearby Oroville Municipal Airport. However, since the commercial facilities are not generally thought to be as sensitive to noise impacts as residential uses that are allowable by right on the property, and because of the relatively low level of daily flights at the airport, the noise impacts of aircraft operation are less than significant. ^ Butte County Department of Development Services ^ Planning Division ^ Page 25 ^ Project Name: Henn General Plan Am. ,ent and Rezone, File # GPA/RZ 02-02 lYlitigation Measure #8: During construction, project contractors or others hired by the project applicant to construct the project are subject to the foilouring measures to reduce noise levels: (a) Locate stationary construction equipment on portions of the site away from adjacent residential properties (b) Shut off idling equipment (c) Notify adjacent residents in advance of construction work (d) Install acoustic barriers around stationary construction noise sources to comply with local noise control requirements (e) Limit the hotrrs of construction to between 8:00 A.M. and 7:00 P.M. (f) Equipment and trucks used for construction shall utilize the best available noise control techniques (including mufflers, use of intake silencers, ducts, engine enclosures and acoustically attenuating shields or shrouds) in order to minimize construction noise impacts on nearby noise-sensitive uses Plan requirements: Requirements shall be noted on building plans. Timing: Compliance is required during all site preparation and construction periods.

Induce substantial population growth in an area, either directly (for example, by proposing new homes and businesses} or indirectly (for example, through X extension of roads or other infrastructure? b. Displace substantial numbers of existing housing, necessitating the construction of replacement housing X elsewhere? c. Displace substantial numbers of people, necessitating the construction of re lacement housin elsewhere? X Impact Discussion: Butte County population has grown at a rate at or below all official population projections for the past ten years. Projected population for 2000 was 207,159, while the actual census population was 203,171. The percentage increase in population for Butte County between 1990 and 2000 was 11.6 percent, an equivalent of 1.1 annual, compounded growth rate. The proposed project would reduce the land area available for residential development and multifamily residential development in particular by a minimal amount. This is not considered a significant amount and would not significantly affect the population of the azea. The project would not displace individuals or housing. No impact would occur. ^ Butte County Department of Development Services ^ Planning Division ^ Page 26 ^ r-~ Project M'amc: Henn Gen~Tal Plan An :ent and Rezone, File ~ GP`VRZ 02-02 1~1itiQation Measure: None required 4.13 PUBLIC SERVICES: Potentially Less Than Less Than No Reviewed Would the proposal: Significant Significant Signifcant Impact Under Impact with Impact Previous Mitigation Document [ncorporated a.

Fire rotection? X e. Police Protection? X d. Schools? X e. Parks? X f. Other ublic services? X a' Impact Discussion: The project is not located in an area that is especially prone to fire hazards. The project would result in the landscaping and conversion of grassland, which is more susceptible to fire than the uses proposed on-site. Fire protection services for the project site are provided by the Butte County Fire Department. The Butte County Fire Department'Califomia Department of Forestry reviewed the proposal and indicated that a pressurized water system for fire protection is required. In addition, the Department requires that the turning radii of all corners around proposed buildings accommodate fire apparatus and that fue extinguishers be mounted on the exterior of all buildings every 75 feet. These requirements have been set-forth below as a mitigation measure for this project. The proposal would result in an incremental increase in demand for police protection services. The cumulative impacts of residential development in the County impacts the ability of the Sheriffs Department to adequately provide police services to outlying areas. Sheriffs facilities fees are required to be paid prior to issuance of building permits; this would reduce the impacts to a less than significant level. This Mitigation shall be incorporated into the Conditional Zoning Agreement. The proposal would not generate demand for school facilities in the area. The project would not create significant impacts to area parks and facilities. A less than significant impact is anticipated to other public services. 1litipation Measure #9: A development impact fee for Sheriffs facilities shall be paid pursuant to the provisions of Chapter 3, Article II of the Butte County Code, prior to issuance of building permits. The fee amount will be determined and calculated as of the date of application for the building permit. Plan Requirements: Payment of Sheriff Impact fees.

Impact Discussion: The property has access from Oroville Dam Road (State Highway lb2). The project would result in an increase in vehicle trips on this road and others in the area compared with existing conditions. In the Institute of Traffic Engineers Trip Generation manual, Sixth Edition, the results of several regression analyses are presented that attempt to describe the traffic generating impacts ofmini-storage facilities. Results are summarized in Table 5. Table S Trip Generation of Mini-Storage Facilities Facilitated by Project Square Feet of Mini-storage (in 1OO0 Sq. Ft.)

The A.M. peak hour is between 7:00 and 9:00 A.M. and the P.M. peak hour is between 4:00 and 6:00 P.M. The Saturday peak hour is for the proposed use, not the peak hour of traffic on adjacent roadways. The existing level of traffic along Oroville Dam Road, which is a two lane road near the project area, is approximately 7,000 average daily trips. The project will add approximately 160 daily trips on weekdays, 149 trips on Saturdays, and 114 trips on Sundays. This level of traffic increase over the course of a day will not impact level of service on Oroville Dam Road. The additional peak-hour trips associated with the project would be approximately ten to 25 trips, approximately half of which would be entering and half exiting. Since Oroville Dam Road has a bi-duectional center turn lane for left turns, the level of service during peak hours is nat expected to be significantly impacted. The existing zoning would allow medium density residential use and other uses that may have higher traffic-generating impacts than mini-storage facilities, depending on the intensity. The Butte County Zoning Ordinance specifies parking requirements for several different uses. Mini-storage facilities are not specifically included, but the Dtrector of Development Services, or his or her designee will review the proposal for the provision of parking to determine adequacy. Site plans will be reviewed for adequate emergency access, as required by the mitigation measure below. ^ Butte County Department of Development Services ^ Planning Division ^ Page 30 ^ Project Name: Henn General Plan An. .gent and Rezone, File tl GPAIRZ OZ-02 IVlitisation Measure #11: The site shall be designed to allow safe and convenient access for emergency vehicles.

Impact Discussion: The project is not expected to generate a large volume of effluent that will require treatment, nor will the project generate a large demand for water service since it involves the development of amini-storage facility. Thus, the project would not have a significant impact on any wastewater or water treatment facilities. Some off-site storm water drainage improvements may be required due to development of the project site. These improvements will be specified in the storm water management plan required by the Regional Water Quality Control Board and by the Public Works Department (referenced in the Hydrology Section of this Initial Study). ^ Butte County Department of Development Services ^ Planning Division ^ Page 31 ^ ~ "~ Project Name' Henn General Plan A ~~~~cnt and Rezone, File # GPAIRZ 02-02 The land use change from multi-family residential to commercial for development of amini-storage facility may change the stream of waste being deposited in the Neal Road Landfill. Since mini-storage facilities are established for personal storage of possessions, and since living in the storage spaces is prohibited, this use of the property may decrease the demand for solid waste services compazed to multifamily residential uses developed in accordance with the existing zoning. According to the Butte County Public Works Department, the Neal Road Landfill is expected to reach maximum holding capacity by the year 2018. The project would not have a significant impact on solid waste disposal.
