DETERMINATION OF NONSIGNIFICANCE Date of Issuance:03/31/2026 Proponent:Catherine Pourtau Lead Agency:KITSAP COUNTY Location of proposal:13251 Westbrook DR SW, Port Orchard, WA 98337, Kitsap County; 4851-000-027-0001 Description of Proposal:POURTAU - Type II - Critical Area Buffer Reduction (25-02534); Critical Area Buffer Reduction to Address Unnamed Stream on Northern Border and Minter Creek to the East for Proposed Revised 30' x 36' Garage Workshop SEPA Determination:The lead agency for this proposal has determined that it does not have a probable significant adverse impact on the environment. An environmental impact statement (EIS) is not required under RCW 43.21C.030(2)(c). This decision was made after review of a completed environmental checklist and other information on file with the lead agency for consistency with KCC Title 17 Zoning, Title 19 Critical Areas, Title 22 Shoreline Master Program and Title 12 Stormwater. This information is available to the public on request. Comment Period:This DNS is issued after using the optional DNS process in WAC 197-11-355. There is no further comment period on the DNS. COMMENTS:The Department received one comment concerned about protection of his well. Mitigation area has been proposed equivalent to the impact to enhance the buffer to the unnamed Type F stream on the property. Conditions:Project shall follow Stormwater controls and provisions in Title 12.Subject to the conditions of the Critical Area Assessment & Mitigation report prepared by BGE Environmental, LLC. dated March 12, 2026, associated with this permit and on file at the Department of Community Development.Wetland buffer reduction of 50%, from 225ft to not less than 112.5 ft. A 112.5-foot native vegetation buffer must be maintained along the delineated wetland boundary as depicted on the approved site. In addition, a building or impervious surface setback line of 15 feet is required from the edge of the buffer.Stream buffer reduction for the Type F water to the north is reduced more than 25% but less than 50%, resulting in a buffer reduction from 200 ft to 140 ft. A 140-foot native vegetation buffer must be maintained along the delineated wetland boundary as depicted on the approved site. In addition, a building or impervious surface setback line of 15 feet is required from the edge of the buffer.Prior to occupancy, the common boundary between the STREAM/WETLAND buffer and the adjacent land shall be permanently identified with critical area buffer signs. Critical Area Ordinance (CAO) signs shall be placed along the designated boundary spaced approximately 50-feet apart, visual from sign to sign. Signs must be attached to existing trees with diameter breast height greater than 4 inches. Alternative methods include 4x4 posts, metal posts or split rail fencing.Signs are provided at issuance and installation of the signs is required prior to final inspection and Certificate of Occupancy (CO). There shall be no clearing of vegetation or grading in the buffer area, as is depicted on the approved site plan. Prior to any clearing or development, please contact Development Services and Engineering Environmental staff at (360)337-5777 to confirm buffer boundaries.Due to area constraints from the on-site stream and associated buffer, the application of a Habitat Management Plan (HMP) shall be implemented on-site to compensate for a buffer reduction at the minimum necessary to accommodate the proposed development. The minimum stream buffer applied on site is 140 feet and wetland buffer of 112.5 feet, as shown on the approved site plan. This buffer reduction is not greater than 25% of the required buffer. In addition, a building or impervious surface setback line of 15 feet is required from the edge of the buffer.Vegetation planting shall occur as specified in the approved planting plan produced in support of this permit. Planting of native vegetation shall occur within the first dormant season once the permitted project has been constructed and approved. When planting is complete, the applicant must contact Development Service and Engineering Staff at (360)337-5777 for a site inspection and as-built approval. Monitoring and maintenance of the planted area shall be conducted for three years after DCD staff approves planting. Monitoring includes live and dead vegetation counts and records of all maintenance activities. Maintenance activities can be defined as, but are not limited to, removal practices on invasive or nuisance vegetation and watering schedules. Monitoring information shall be summarized in a letter with photographs depicting conditions of the vegetation and overall site. Monitoring reports are due to Kitsap County Department of Community Development Services and Engineering Division by December 31 of each monitoring year. If more than 20 percent of the plantings do not survive within any of the monitoring years, the problem areas shall be replanted, and provided with better maintenance practices to ensure higher plant survival.
