The subject property is proposing two- and three-unit buildings with an increase in the maximum wall plate height up to 32 feet to allow for a third floor within the residences. The 1.69-acre site located along Talbot Rd S at S 48th St within the Residential-14 (R- 14) zoning district (3123059022). The proposal includes 20 new fee simple lots, a 13,130 square foot open space/tree retention/stormwater tract, a 20-foot wide north-south alley, and a 47 to 53-foot wide east-west public road through the property. The residential lots would range in size from 1,620 square feet to 2,775 square feet with an average lot size of 1,989 square feet. The project would result in a net density of 15.2 dwelling units per net acre. The existing single family home and accessory buildings would be demolished. The design of the primary access road from Talbot Rd S would be via a modified limited residential access street until it meets the supplemental alleyway before widening to a residential access street. The alleyway crosses the residential access street and spans the full length of the property. The street modification request includes one-foot less right-of-way dedication on Talbot Rd S in order to match the existing street section. Site soils consist of Alderwood (AgC) gravelly sandy loam at a depth of about 8 feet with advance outwash deposits from a depth of 8 feet to 13 feet. The advance outwash soils may support limited infiltration to go along with the proposed 33 ft by 60 ft stormwater detention vault. The existing site slopes to the west at 5 to 8 percent. Upon completion of the project, roughly 95 percent of the site is proposed to be graded with approximately 2,000 cubic yards of cut and approximately 4,000 cubic yards of fill material. The site contains 71 significant trees. The project is proposing to retain four (4) exiting trees in a combined tree retention tract and is also proposing 42 replacement trees onsite. The applicant has submitted a Geotechnical Engineering Report, Preliminary Technical Information Report, Wetland Reconnaissance, Wetland Review Letter, Arborist Report, Letter of Understanding of Geologic Risk, and Trip Generation Report.

SEPA Environmental checklist (WAC 197-11-960) July 2016 Page 1 of 14 SEPA ENVIRONMENTAL CHECKLIST Purpose of checklist: Governmental agencies use this checklist to help determine whether the environmental impacts of your proposal are significant. This information is also helpful to determine if available avoidance, minimization or compensatory mitigation measures will address the probable significant impacts or if an environmental impact statement will be prepared to further analyze the proposal. Instructions for applicants: This environmental checklist asks you to describe some basic information about your proposal. Please answer each question accurately and carefully, to the best of your knowledge. You may need to consult with an agency specialist or private consultant for some questions. You may use “not applicable” or "does not apply" only when you can explain why it does not apply and not when the answer is unknown. You may also attach or incorporate by reference additional studies reports. Complete and accurate answers to these questions often avoid delays with the SEPA process as well as later in the decision- making process. The checklist questions apply to all parts of your proposal, even if you plan to do them over a period of time or on different parcels of land. Attach any additional information that will help describe your proposal or its environmental effects. The agency to which you submit this checklist may ask you to explain your answers or provide additional information reasonably related to determining if there may be significant adverse impact. Instructions for Lead Agencies: Please adjust the format of this template as needed. Additional information may be necessary to evaluate the existing environment, all interrelated aspects of the proposal and an analysis of adverse impacts. The checklist is considered the first but not necessarily the only source of information needed to make an adequate threshold determination. Once a threshold determination is made, the lead agency is responsible for the completeness and accuracy of the checklist and other supporting documents. Use of checklist for nonproject proposals: For nonproject proposals (such as ordinances, regulations, plans and programs), complete the applicable parts of sections A and B plus the SUPPLEMENTAL SHEET FOR NONPROJECT ACTIONS (part D). Please completely answer all questions that apply and note that the words "project," "applicant," and "property or site" should be read as "proposal," "proponent," and "affected geographic area," respectively. The lead agency may exclude (for non-projects) questions in Part B - Environmental Elements –that do not contribute meaningfully to the analysis of the proposal. A. Background [HELP] 1.
