Document Description
The proposed project involves the clearing of vegetation, earthmoving and land contouring, and installation and maintenance of erosion control measures associated with the development of approximately 1.24 gross acres (i.e., proposed development area or project area) with approximately 1.09 net planted acres in one proposed vineyard block on 5.67 acre parcel. Slopes in the proposed development area range from 22 percent (%) to 40%, with an average slope of 30%. Per Ordinance No. 1438, Section 17 earthmoving activities associated with an agricultural project of five (5) acres or less on slope of less than 30% can utilize a one-time exemption whereby the project is required to comply with the Conservation Regulation in effect prior to the effective date of Ordinance No. 1438. As such, the project is exempt from the vegetation requirements of Napa County Code (NCC) Section 18.108.020. Approximately 45 trees, impacted by fire, would be removed as part of the proposed project. Per new Bay Area Air Quality District Management District policies in regards to Green House Gas (GHG) emissions, the project is required to result in no net decrease in sequestration capabilities. A GHG analysis was prepared for the project and demonstrated no net decrease in sequestration capabilities of the parcel as a result of the proposed project. While exempt from 18.108.020 the project does involve the removal of existing mapped oak woodland and, as such, the project must comply with General Plan Policy CON-24. The applicant has identified 2.34 acres of mapped oak woodland forest to be designated as a permanent preserve to meet the 2:1 preservation requirement of Policy CON-24. All temporary debris, vegetation, soil and soil amendment stockpiles and storage areas, if needed, will be located within the proposed vineyard development area and clearing limits. The proposed vineyard would be irrigated with approximately 0.46 acre-feet (AF) of groundwater annually (reducing to 0.31 AF annually once the vineyard is established) from one existing well located adjacent to the proposed vineyard block. Irrigation pipelines would be located within the proposed development area, with the exception of the main line that would connect the groundwater well to the proposed development area. Minimal rocks are expected, but any encountered during development of the proposed project would be stored or buried within the proposed development area or used for vineyard avenues or landscaping.
