August 15, 2025 City of Yelm Community Development Attn: Cody Colt, Public Services Director 106 2nd St SE Yelm, WA 98597 Re: Yelm Crossing LLC., Prairie Habitat Critical Area Recon and ESA No Effect Letter, Thurston County Parcels #64303100900, 64303100800, and 64303100801. Located at 16910 State Route 507 SE, Yelm, Washington, Section 29, Township 17 North, Range 02 East, W.M., and in accordance with the Thurston County Critical Areas Ordinance Title 24.03 (Definitions), Interim Prairie Ordinance 14542, WDFW Management Recommendations for Washington Priority Habitats Oregon White Oak Woodlands and WDFW Habitat Management Recommendations for the Mazama Pocket Gophers, following the 2022 USFWS Mazama Pocket Gopher Screening Protocol, Thurston County’s 2022 survey protocol, and the City of Yelm Code; Title 14 environmental. Dear Mr. Colt, Key Environmental Solutions, LLC. (KES) has completed a Prairie Habitat Area Recon on the above referenced parcel located at 16910 State Route 507 SE, Yelm, Thurston County, Washington. Fieldwork was conducted on July 25, 2025, and August 27, 2025. Project Description and Findings The parcels were reviewed and are approximately 16.02 acres located in eastern Thurston County, in the city of Yelm. Parcels 64303100900, 64303100800, and 64303100801 are currently developed with Long Shots indoor shooting range. The parcels were reviewed for prairie habitat and Mazama Pocket Gophers. When the site is developed with commercial development, there will be not any “Take” of any state or federally listed species. There will be “No Effect” on prairie habitat, Mazama Pocket Gophers or any other critical areas or buffer impacted. KES reviewed Washington Department of Fish and Wildlife’s (WDFW) Priority Habitat Species (PHS) lists and maps and no listed species were found to occur onsite. Adjacent areas were also looked at for any critical areas or listed species, and none were found to occur. In 2010, in the far northeast corner of Parcel 64303100900 Mazama Pocket Gophers (Thomomys mazama) were supposedly found. KES carefully reviewed this area and did not find any evidence of Mazama Pocket Gophers. Yelm Crossing LLC Parcels 64303100900, 6430310080, & 643100801 Key Environmental Solutions, LLC.

No Effect Mazama Pocket Gopher & Prairie Survey September 2, 2025 3 The project area was required to be reviewed due to the presence of prairie soils. KES reviewed the Natural Resource Conservation Service Soils (NRCS) maps and verified that prairie soils did not exist in the project area. Soil Types Prairie Soil Spanaway gravelly sandy loam, 0 to 3 % slopes Yes Mapped prairie soils do not necessarily mean that the area is a prairie –vegetation, landuse, development, and historical land practices may have changed the soil conditions. Current site conditions may or may not accurately reflect mapped soils. Conversely, prairies may be found in areas where the soils are not mapped as prairie soils. Federal ESA Species, Habitats and No Effect There are no Federal ESA species or habitats that exist within the parcel. There will be “No Effect” and/or “No Take” from the proposed project. Historically, the parcel was part of a large farm. In the 1990 aerial, this parcels was part of a large farm and also had several industrial buildings. All of these building were removed between 2002-2007. KES has performed two site visits as required. KES determined that parcel does not meet the definition of prairie from USFWS and that there has been no Mazama Gopher occurrence found on adjacent parcels or anywhere in the vicinity. Numerous mole mounds were found onsite. A previous prairie/gopher report was performed in 2022 and did not find any Mazama Pocket Gophers. Walmart and the parking lot are the most recent construction in the area. It is located to the east Walmart Boulevard SE. It is KES’s professional opinion that development of this parcel with a commercial development, will not impact any prairie species or any other critical areas and should be permitted. KES concurs with the proposed site plan. Yelm Crossing LLC Parcels 64303100900, 6430310080, & 643100801 Key Environmental Solutions, LLC.
