Mason County recognizes Dear MS. Miller: that its employees& volunteers are the This letter documents the assessment of the Mason County Public Works foundation upon which Department's proposed salt shed nd potential impacts to Mazama pocket these services are provided. Thomom s mazama The proposed project is located at 100 Public gopher( Y )• p p p j Works Drive, Tax Parcel Number 42002-21-90010. The project is to construct a 120-foot by 65-foot(7,800 square-feet) salt storage structure in the Public Works facility's actively used materials staging yard. For this assessment we examined available information including: ■ Design drawing showing proposed and existing structures (attached); ■ Current and historical aerial imagery showing the developed/disturbed character of the site and vegetated condition of surrounding areas (see Figure 1); ■ Natural Resources Conservation Service mapped soil types (Figure 2) showing"Gh," Grove gravelly sandy loam, 0-5 percent slopes in the vicinity;this was reviewed for comparison with known pocket gopher preferred soil types and; ■ Washington State Department of Fish and Wildlife Priority Habitat and Species (PHS) data. We also walked the premise several times in the summer and fall during the standard pocket gopher survey season (between June 1 and October 31), including within the stockpile area surrounding the proposed building site and the area of known pocket gopher occupied habitat;the grassy area to the south of the proposed project. 1 Ms. Grace Miller November 26,2019 EXISTING STOCKPILE/STAGING AREA AREA OF KNOWN MAZAMA POCKET GOPHER OCCUPANCY,''"? Earth Figure 1.Aerial Image Showing Approximate Project Location and Vicinity. A, Figure 2. Mapped Soil Type in Project Vicinity. Page 2 of 4 Ms. Grace Miller November 26, 2019 Summary of Findings Based on the review of existing conditions,the project is unlikely to affect Mazama pocket gopher. Mazama pocket gophers are not expected to be present in the construction area and the area does not provide suitable habitat that would potentially be used by Mazama pocket gophers. The proposed structure will be located in area th t has experienced active use as a material staging area(for sand and gravel)with frequent equipment operation, ground disturbance, and compaction. This use is evident from existing conditions observable on the ground and aerial imagery (Google Earth) dating back 10 years to 2009. A grassy area of known pocket gopher occupied habitat is located to the south on the opposite side of an existing fence and access roa leading to the water reservoir tower. The grassy area exhibits signs of active use by Mazarria pocket gophers including numerous indicator mounds observed by Public Works biologist in 2019, and presence is documented by Washington Department of Fish and Wildlife PHS data'. However, mounds indicating occupancy are more than 200 feet from the prop sed structure and the proposed structure is located in a highly disturbed, effectively developed area comparable to impervious surface. No mounds were observed north of the fence. The developed area does not contain vegetated habitat that would be suitable for, or potentially used by,pocket gophers. Since pocket gophers tend to travel relatively short distances from burrows for foraging and longer distances only for population dispersal into suitable habitats,the potential for presence of individuals in the active stockpile yard is unlikely. Based on existing conditions including ongoing equent disturbances, ground compaction, lack of mounds that would indicate presence or t se, general lack of suitable habitat such as vegetation that could provide foraging opportuni ies, and typical traversing and dispersal patterns of pockets gophers, it is also highly unli cely that subterranean occupancy is possible north of the fence or within 200 feet of the project. Recommendation The existing conditions characterized by compacted gravel and material stockpiles reflect conditions similar to large areas of impervious surface that would preclude potential habitation. The conditions would also preclude the need for additional survey according to generally accepted practices in the field and current screening protocols established for neighboring counties where Mazama pocket gopher populations are federally listed. We recommend the project as proposed does not warrant additional survey or review for potential impacts and/or protection of Mazama pocket gopher.

No stormwater shall be conveyed to the county ditch or waters of the state. DETAILS Grace Miller attended the meeting on behalf of gbm@co.mason. 10/21/19 10/21/19 the Planning Department.The property is Zoned wa.us as Public Institutional.The proposed use meets the zoning requirements and criteria. This area contains potential pocket gopher habitat.The pocket gopher habitat is regulated by the Mason County Resource Areas Ordinance as a Fish & Wildlife habitat Conservation Area.A pocket gopher observation letter, prepared by an environmental consultant, should be submitted to the planning department to determine if the area where the building is being proposed is being used by pocket gophers. If it is, a pocket gopher study, by an environmental consultant, will be required.This report would include habitat mitigation for the pocket gophers.The property is also located on a Critical Aquifer Recharge Area that is regulated under the Aquifer Recharge Area Chapter of the Mason County Resource Ordinance. The development is proposed on a Class II Highly Susceptible Critical Aquifer Recharge Area.The stormwater plan should address any potential impacts to the aquifer from the development.
