2021.0325.PR0009 SEPA Comparison Table Stor-House-Creek-Road 05-28-2021The Stor-House Self-Storage - Yelm, SEPA Impacts Comparison Table IMPACTS CONTEMPLATED UNDER CREEK ROAD MIXED USE DEVELOPMENT (City File No. 20070404) Approved Site plan attached as Exhibit A CURRENT PROPOSAL (STOR-HOUSE YELM) Proposed Site plan attached as Exhibit B Site preparation will require grading activities for access ways, building pads, etc. Approximately 50,000 cubic yards of fill and 1,500 cubic yards of cut will be necessary for the completed project. No additional impacts are proposed. Minor grading may be needed to prepare the site for installation of building foundations. No fills are proposed. No additional impervious surface is proposed. Emissions from automobiles using the property; temporary exhaust and dust particle emissions associated with construction activity. No additional impacts are proposed.SurfaceA Type F stream and Class IV wetlands are located along the eastern property line of the proposed project. The project site, which is situated on the west side of the original mixed use development, is over 200 feet from the stream and associated wetland. Developed conditions, which inlude the Tustin Apartments, exist between the project site and stream.GroundThe site is located in a critical aquifer recharge area. Regulations to protect the aquifer will be followed No additional impacts are proposed. RunoffThe proposed project site will contain an underground storm water infiltration system. The stormwater will flow through catch basins located in drive aisles to through a treatment system before being conveyed to the underground detention system. A City-approved storm drainage system was previously designed and constructed to handle runoff from the entire project at full build-out in order to mitigate any adverse impacts from stormwater runoff. The proposed project will connect to this existing system. During construction, temporary erosion control measures will be used. After construction, all site runoff will continue to be directed to the permanent storm water collection/treatment facility. All existing vegetation outside the wetland buffer will be removed. A professionally-designed landscape plan will incorporate native species and incorporate complementary landscape material. Some of the existing landscaping will be removed to accommodate the proposed new improvements. Once construction is complete, new plantings will be added to restore landscape buffers around the site. No threatened or endangered species are known to exist on or near the project site. Maps indicate the property contains soils moderately suitable as habitat for the Mazama Pocket Gopher, a protected species listed on the Washington Priority Species and Habitat List as well as the Federal Threatened Species List. The site has been developed, is mostly paved with graded building pads. Visual reconnaissance shows no evidence of gopher activity. Minor impacts due to temporary construction activities. No additional impacts are proposed. Minor impacts will occur due to temporary construction activities. No adverse impacts to surrounding property uses. Sensitive areas, including aquifer, stream and wetlands will be preserved. Proposal is generally consistent with existing City of Yelm Comprehensive plan and Zoning. No additional impacts are proposed. Proposed project is still consistent with the Comprehensive Plan and Zoning policies put in place by the City.

No additional impacts are proposed. The project will be designed to be consistent with the City of Yelm Guidelines. Proposed structures will not exceed allowed height limits. The height of the building will be approximately 40 feet. The exterior of the building will be concrete modular units (CMU) and metal siding. The exterior will feature alternating colors and materials and a parapet roof line topped with a cornice and featuring transitions in height. The structure will be of a scale and size that will be compatible with the surrounding buildings. Colors will be tasteful and residential in theme. Light and glare will originate from reflective surfaces, exterior lighting and light from vehicles using the site. No additional impacts are proposed. Some lighting may be used to enhance the security of the buildings at night, but the effect on surrounding properties will be minimal. These impacts would occur primarily in the evening and before dawn. No recreational uses will be displaced by this project. No additional impacts are proposed. No historical or cultural items of significance are known in the vicinity. No additional impacts are proposed.StreetsThe proposal will not require any new roads or streets. Frontage improvements will be provided along Creek St SE. No additional impacts are proposed. All frontage improvements were constructed in conjunction with the original proposal.TrafficA traffic study will be conducted at a later date. At this time there are no proposed measures to reduce or control impacts. Self-storage is one of the lowest traffic generators and has less traffic than typical retail, office, business and even residential subdivisions. According to previous traffic studies conducted by the applicant, similar- sized storage facilities generate as few as 10-15 PM peak hour trips.ParkingThe proposed project will provide a total of approximately 527 parking stalls for the entire mixed use development. The proposal will eliminate only the parking stall associated with the existing use and accessory buildings. The project would eliminate the existing parking lot improvements and 71 parking spaces to make way for the new structure, but would add 24 new parking stalls: 8 near the retail/leasing office, 5 in the loading bay, and 11 near the exit gate. Parking for the entire project will meet City requirements for retail (1 stall per 250 square feet of gross floor area) and general industrial use (1 space per employee based on the greatest number of employees on a single shift, plus one for each vehicle owned or operated by the company).

No additional impacts are proposed at this time. In fact, the current proposal will have even less of an impact on public services. Self-storage is a low-intensity use. The number of people present at any time on the site that may require emergency services (such as fire, health, and police services) is relatively small compared to other types of land uses. The proposed project will use the following utilities: Electricity, water, refuse, telephone, sanitary sewer. No additional impacts are proposed. All utilities, including sewer and water, were extended throughout the site as part of the previous development proposal. Utility connections may need to be reloacated to serve the proposed building.
