The Project is consistent with VLDR (Very Low Density Residential, 1-acre minimum parcel size) zone and the Very Low Density Residential General Plan Land Use designation, as well as with the policies of the other elements of the General Plan. The Project will create fifteen (15) new lots ranging in size from 1.08 to 1.33 acres, consistent with the minimum one-acre parcel size of the VLDR zone. Each parcel is designed to accommodate single-family residences, accessory uses, and structures compatible with the surrounding area's existing development and character. General Plan Goals and Policies applicable to the Project are identified in the General Plan Consistency Review table, contained in the Project's agenda report, and conclude the Project's consistency with each applicable goal and policy. B. The design and improvements of the proposed subdivision map are consistent with County's standards and policies, provided all conditions of project approval are complied with. Each parcel conforms to the applicable design and improvement standards in Butte County Code Chapter 20 and the Butte County Improvement Standards. Improvements to new and existing roads serving the new lots are consistent with the City's road standards. C. The project site is physically suitable for the type and density of the proposed development. Each parcel's size and configuration allow development consistent with zoning's density and are capable of supporting residential land uses permitted by the VLDR zone. D. The design and improvements of the Project will not cause substantial environmental damage or substantially and avoidably injure fish or wildlife or their habitat. The Project was evaluated through the preparation of an Initial Study prepared pursuant to the California Environmental Quality Act. The study did not identify any significant adverse environmental impacts caused by the Project, provided that recommended mitigation measures are incorporated into the Project. E. Approval of this project will not be detrimental to the public's health, safety, and welfare. The Project has been reviewed by County, local, and State agencies for consistency with regulations established to protect the public's health, safety, and welfare, including regulations relating to sewage disposal, domestic water, and access. Conditions are included with the Project that would ensure that the Project will not be detrimental to the public. F. The design and improvements of the Project will not conflict with easements acquired by the public at large for access through or use of property within the proposed subdivision, provided the attached conditions are met. A review of the preliminary title report for the subject property did not identify any public access easements that would conflict with the project's proposed design.
