Current Zoning: SR -1 (Suburban Residential, 1 -acre parcels); OS (Open Space) . I. General Plan Designation: AR (Agricultural Residential) J. Environmental Setting: The property is currently developed with a walnut orchard. There are no other improvements. The terrain is flat, with no defined drainage courses. The property is located within the North Chico Specific Plan. The western portion of the property fronts on SR -99. A county - designated arterial, Kittyhawk Drive, would be developed along the properties south botmdary from Hicks Lane to SR -99. The property, is shown to be in a 100 year flood zone. K Surrounding Land Uses: The property's west boundary fronts on SR -99. A residential subdivision (Autumn Park), is located adjacent to the east. Other undeveloped lands lie to the north and south. L. Proiect Description: The applicant requests the immediate cancellation of a Williamson' Act Contract pursuant to Government Code Section 51280 — 51287, on a 52.72 acre parcel. A Tentative Subdivision Map, (Kittyhawk Park) has been submitted concurrently proposing to create, 48, 1 -acre single family residential parcels. The Tentative Map application is currently considered incomplete and is not being considered for approval at this time. This Initial Study reviews the impact-; associated with the cancellation, but also discloses impacts that could be related to the approval o° the 48 lot residential subdivision. Note: This project has been reviewed for consistency with the Adopted North Chico Specific Plan (NCSP) goals and polices and will utilize the adopted Certified Environmental Imract Report (CEIR) prepared for the plan as the basic environmental document. The NCSP is a. mixed-use large scale development plan, which serves as a broad • reaching site planning too] for larger developments in the unincorporated North Chico area.. These documents were adopted by the Board of Supervisors in March of 1995.

B. 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 -)roject 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 a 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) Once the lead agency has determined that a particular physical impact may occar, then the checklist answers must indicate whether the impact is potentially significant, less that 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 tothe 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 discu::sion 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 ■ Butte County Department of Development Services ■ Planning Division ■ .Page ■ 49. Project Name: Liptrap Immediate Cancellation of Williamson Act Contract (Canc 04-02) applicable legal standards, and state whether such effects were addressed by mitigation measures based on the earlier analysis. c) Mitigation Measures: For effects that are "Less Than Significant with Mitigation Measures Incorporated," describe the mitigation measureswhich were inco.porated 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 informaton sources for potential impacts (e.g., general plains, 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; aad b) The mitigation measure identified, if any, to reduce the impact to less than sigaifrcant. 4.0 ENVIRONMENTAL IMPACTS: 4.1 AESTHETIGVISUAL RESOURCES: Impact lltscusston: The proposed Williamson Act Cancellation would remove the restrictions associated with the Williamson Act concerning residential development but would not, by itself, allow for development.

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: a. The Immediate Cancellation proposed would result in the conversion of farmland since the current ` walnut orchard would become available for the development of 1 -acre lots upon removal of the Williamson Act Contract, as proposed under the Kittyhawk Park Subdivision application. However, the North Chico Specific Plan has designated this area for residential development at a 1 -acre density. This property is located in an area that has been designated by the County General Plan for urban uses not agricultural uses. The CEIR for the North Chico Specific Plan reviewed the impact of the North Chico Specific Plan on agricultural land uses. The CE1R noted that implementation of the Specific.Plan would result in the t conversion of approximately 475 acres of agricultural lands. However, because 213 acres of these soils are not considered prime agricultural soils and because the remaining,262 acres are :substantially in conflict with adjacent residential development, *and are located on the urban side of the Greenline, this is considered a less -than -significant impact. The CEIR father explains'that the County's existing Greenline Policy establishes SR -99 as the boundary between •urban/sub4ban to the east and agricultural to the west. Therefore, the agricultural portions of the plan area are not located within an area identified for permanent agricultural use, and no impact would is anticipated. b. The approval of the Immediate Cancellation would remove the Williamson Act contract_ The Butte County Land Conservation 'Advisory Committee reviewed the findings required under the Government Code (Williamson Act) and has made a recommendation that the findings can be made in this instance. The Committee reviewed the impact of the Immediate Cancellation on surrounding Williamson Act Contracts and agricultural land and determined that the cancellation would not have a negative influence on these lands.

Further development would be contingent upon the approval of the Kittyhawk Park Tentative Subdivision Map' which has been concurrently submitted (Planning Division File #TSM 04-11). This application is currently incomplete. The California Department of Fish and Game Natural Diversity Data Base was consulted with respect to the presence 'of sensitive plants and animals and their habitats. According to the Natural Diversity Data Base, the project is not located in an area considered to contain these resources. GIS land coverage data supplied by the California Department of Forestry and Fire Prevention shows that the project site is designated.as "Agriculture", not as any viable habitat type. The CEIR of the NCSP was also consulted concerning this project area. Figure 6-1 of the CEIR for the NCSP shows that orchards are the predominant vegetation type in this area: As described in the Project Setting section of this Initial Study, walnut orchards continue to occupy the subject property. The CEIR indicates that orchards are of little direct value to native biological resources other than insects, because agricultural practices keep plant species diversity to a minimum, and little nesting or foraging habitat is available to wildlife. Some of the species that can take advantage of agricultural habitats provided in the Plan area are deleterious to productivity and are consequently discouraged and/or prevented from foraging there. The CEIR also states that, orchards can play a role in providing a lot -disturbance buffer between . developed areas and biologically rich riparian habitat that is present in some locations of the Plan area. In the case of the proposed Kittyhawk Park Tentative Subdivision Map there are no riparian resources present. The CEIR indicates that there are'several areas of potential impacts to biological resources as a result of NCSP implementation, such as impacts to riparian resources, vernal pools and other ephemeral wetlands; disturbance to nesting areas of the black -shouldered kite and burrowing owl; California Department of Fish and Game Species of Special Concern; loss of foraging habitat for the Swainson's hawk, disturbance/removal of habitat used by the Valley Elderberry Longhorn Beetle; and, disturbance to special status plants in the Plan area. The CEIR indicates that the NCSP contains many project elements that mitigate these impacts to levels of insignificance. There are impacts for which the CEIR recommends further mitigation, but the resources that these mitigations are for are not located on the subject property. Specifically, the CEIR requires Army Corps permits for impacts to wetlands. In the case of the subject property no. Corps Permit is required because CEIR Figure 6.2 Weiland Resources does not identify any wetland resources in the project area. Pre construction surveys are recommended for the presence of'the black -shouldered kite. In the case of the subject property no pre -construction survey is recommended because CEIR Figure 6.1 shows that the property is not located near any trees known to be active black -shouldered kite habitat. Comprehensive rare plant surveys are recommended on all land designated for development. In the case of the subject property no rare plant surveys are recommended since this property is 'developed with an orchard, a vegetation type and use that preclude the presence of rare plants, due to the amount of disturbance associated with this agricultural activity as explained above. . The design of the proposed project will not cause environmental damage to fish and wildlife or their habitat, and a "de minimis" exemption regarding impact to fish and wildlife or their habitat is recommended. The collection of fees pursuant to Fish and Game Code Section 711.4 and 14 CCR 753.5, is not required at this time. The project site' is not known to contain 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. -The project will not have a substantial adverse effect on any riparian habitat; have a substantial adverse effect on federally protected wetlands as defined by Section 404 of the. Clean Water Act; conflict with any local policies or ordinances protecting biological resources; or, conflict with the provisions of an adopted Habitat Conservation Plan.

Mitigation Measure #3 Cultural Resource Protection Place a note on a separate document which is to be recorded concurrently with the Final Map or on an additional map sheet that states: "Should grading activities reveal the presence or prehistoric' or historic cultural resources (i.e. artifact concentrations, including arrowheads and other stone tools or chipping debris, cans glass, etc.; structural remains; human skeletal remains) work within. 50 feet of the find shall immediately cease until a qualified professional archaeologist can be consulted to evaluate tze find and implement appropriate mitigation procedures. Should human skeletal remains be encounterec, State law requires immediate -notification of the County Coroner. Should the County Coroner determ.ne that the remains are in an archaeological context, the Native American Heritage Commission in Sacramento shall be notified immediately, pursuant to State Law, to arrange for Native American participation in determining the disposition of such remains." The provisions of this note shall be followed during construction of all subdivision improvements, including land clearing, road construction, utility installation, and building site development. ■ Butte County Department of.Development Services ■ Planning Division ■ ,Paged 1 ■ It 57�.

There is some speculation as to the exact location of the historic --arthquake .epicenters and some question if they actually occurred on the Midland-Sweitzer fault (Butte County,. 1977). The Butte County GIS Fault Lines theme shows that a possible fault with activity unknown is located approximately 1.4 miles to the east of the project site. This fault is a.part of the Foothill Shea_ 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. Like most of central California, the site is expected to be subjected to seismic ground shaking at some future time. Accordingly, all buildings, pipes, light poles, roadways, and other improvements would be designed and installed in accordance with Uniform Building requirements. Because the project appears to be located such that the probability of significant ground shaking is low, and because the structures would be designed and installed in accordance with Uniform'Building Code standards for the appropriate Seismic Hazard Zone, potential geologic impacts would be less than significant. The Butte County Seismic Safety Element's Liquefaction Potential Map indicates that the site has a moderate potential for liquefaction. The impact would be less than significant. The Subsidence and Landslide Potential Map of the Safety Element of the Butte County &-neral Plan indicates that there is no potential for landslides in this area. The Subsidence and Landslide Potential Map also indicates that the property is located within an area of heavy groundwater withdrawal and is a potential subsidence area. Although so designated, this designation is general in nature, and is applicable: to virtually all of the Central Valley area of Butte County. Although subsidence is a problem in. all of the Central Valley in California due to groundwater withdrawals for irrigation, there has not been any documented incident that indicates a specific problem at this location. No impact is anticipated. There is no soil erosion potential for this site, according to Butte County General Plan GIS data. The CEIR for the NCSP indicates that implementation of•the NCSP will increase erosion and sediment transport into . vicinity creeks and drainages, if proper erosion control measures are not implemented. The NCSP contains policies (Policy 7.2) concerning grading and erosion control. The requirements from this policy that are applicable to this project and is set forth below as a project Mitigation Measure. The Conservation Element's Expansive Soils Map indicates that the project site has a moderate expansive soil designation. Standard construction practices as required under the Uniform Building Code address the impact of expansive soil on foundations and buildings. No impact is anticipated. The Butte County Environmental Health Division has determined that the property is suitable for the development of individual on-site septic systems for each of the 48, 1 -acre lots proposed by the Kittyhawk Park Tentative Subdivision Map.

The proposal could, nevertheless, afflict surface water quality due to siltation resulting from erosion caused by land clearing, road construction, utility, installation, and building; site, development. Mitigation concerning impacts from these development activities has been set forth below. The Butte County Department of Public Works has commented that the project is located within the 100- year floodplain of Keefer Slough (FEMA Map 06007C0320D, dated April 20, 2000). The Department of Public Works comments that this area has been known to flood more frequently. The project design of the . Kittyhawk Park Tentative Subdivision Map has the potential to alter the floodplain, subjecting future residents and adjacent property owners to increased flood hazards. The Department of Public • Works indicates that the applicant has not provided detailed design information demonstrating that it is feasible to develop within the floodplain, while providing adequate ingress and egress during flood events, and providing suitable building pads above the flood levels, without adversely affecting surrounding properties (Source: Department of Public Works Comments on.TSM 04-11, February.25, 2004). In a .etter_dated December 10, 2004 the applicant indicates that drainage calculations will be provided to the Dep3artment of Public Works to address their concerns. No new information has been received at this time. . The Kittyhawk Park Tentative Subdivision Map application also proposes to abandon an existing retention basin that handles drainage for the adjacent Autumn Park Subdivision and build new retention basins to handle drainage from both the Autumn Park and Kittyhawk Park subdivisions. Any new storm water retention basin benefiting the Autumn Park Subdivision must be constructed and made operatonal to the satisfaction' of the Department of Public Works, Butte County Environmental Health Di-.,ision, and Regional Water Quality Control Board. The Department of Public Works has commented that a complete set of drainage calculations is necessary prior to considering this item as complete. The Environmental Health Division has commented that Lots 6, 7, and 8 of the proposed Kittyhawk Park Tentative Map cannot be approved with the existing (Autumn Park Subdivision) storm drLinage basin shown. No residential lots can be shown on this area until the alternative storm drainage basin is approved and functional, and the existing storm drainage basin is abandoned and deemed suitable for residential uses. This item will remain incomplete until the Department of Public Works is. satisfied with the drainage plan and alternative drainage is provided for the Autumn Park Subdivision. As discussed within the Project Description section of this Initial Study the Kitty Hawk Park Tentative Map application is considered incomplete and is not being considered for approval at this time. This initial Study reviews the impacts associated with the cancellation but also discloses impacts that could -be related to the approval of the 48 lot residential subdivision. . Mitigation for flooding and drainage concerning the Kittyhawk-Park Tentative Subdivision Map is not provided at this time because - the al-7plication is considered .incomplete.
