Hello, On behalf of Ecology’s Shorelands and Environmental Assistance (SEA( Program, I am providing the following comments regarding the City of Federal Way’s SEPA Determination of Nonsignificance (DNS) decision for the Summit View Estates aka Summit at Steel Lake Preliminary Plat: On June 17, 2021, Ecology received a Pre-Filing Meeting Request for a Section 401 Water Quality Certification for the Summit at Steel Lake Property. The reason for this request was for permission to fill in approximately 1,300 square feet of wetlands on the property. The project description provided to Ecology is as follows: The Summit at Steel Lake property (King County Tax Parcel Number 0521049033) is an approximately 6- acre parcel located at the northeastern corner of the intersection of South 304th Street and 11th Avenue South in Federal Way, Washington. The property is currently undeveloped. Two wetlands were confirmed on the property. Both wetlands are Category IV depressional wetlands with habitat scores of 7. Proposed development includes 24 single-family residences and a new road extending northward from South 304th Street. The proposed development will need to fill the two on-site wetlands; protecting the wetlands with their associated buffers would eliminate approximately 10 of the proposed 24 lots, thus making the project infeasible. Since the entire property will be developed, it will not be possible to mitigate for the wetland fill on-site. Therefore, mitigation will occur through the purchase of credits from an accredited wetland mitigation bank whose service area includes the site, or purchase of credits from the King County In-lieu Fee program. No formal Section 401 Water Quality Certification Request was ever received for this project by Ecology, and the SEPA checklist for the project, submitted to the city on July 9, 2021, says the following regarding the presence of wetlands within the project area: a. Surface Water: 1) Is there any surface water body on or in the immediate vicinity of the site (including year-round and seasonal streams, saltwater, lakes, ponds, wetlands)? If yes, describe type and provide names. If appropriate, state what stream or river it flows into. To the applicant’s knowledge there are no surface water bodies in the immediate vicinity of the site. 2) Will the project require any work over, in, or adjacent to (within 200 feet) the described waters? If yes, please describe and attach available plans. No, it will not. 3) Estimate the amount of fill and dredge material that would be placed in or removed from surface water or wetlands and indicate the area of the site that would be affected. Indicate the source of fill material. None. Any wetlands delineated on this property would be considered waters of the state subject to the applicable requirements of state law (see RCW 90.48 and WAC 173.201A) and possibly require a permit under Section 401 of the Clean Water Act (33 USC §1341) and 40 CFR Section 121.2). If the wetlands are determined to be not subject to federal government jurisdiction, they remain state jurisdictional wetlands and will require permitting by Ecology and, potentially, the City of Federal Way in regards to applicable local critical areas requirements. Ecology’s SEA program recommends that the City of Federal Way refrain from issuing permits or permissions that could potentially impacts the on-site wetlands until all required permissions/permits for the proposed wetland impacts are obtained. Please feel free to contact me with any questions regarding the above comments.
