Mullet, Mayor Department of Community Development Steve Lancaster, Director December 29, 2000 Mr. Jerry Knudson c/o Green River Construction 6402 South 144th, Suite 1 Tukwila, WA 98168 Re: SEPA Review (E99 -0029) Proposal to Grade & Fill Special Permission (L2000 -081) Reduce Wetland Buffer to 25 feet 149XX 58th Avenue South, Tukwila Tax Parcel 115720 -0394 Dear Mr. Knudson: We have reviewed the additional items you submitted on December 15, 2000 in connection with the above - referenced applications. Your original SEPA checklist (submitted on September 17, 1999) indicated that you intended to import 1,600 cubic yards of fill for future development on the site. However, your December 15th submission now limits your proposal to the grading work that has already occurred. We have the following comments. SEPA Determination: A SEPA Determination is required whenever 500 cubic yards of import or export is anticipated. Given the change in your proposal described above, a SEPA Determination will not be needed at this time. We have closed your SEPA file and have enclosed a refund of your application fee in the amount of $325.00. Reduction in Wetland Buffer: As you know, there is a Type 2 wetland on your neighbor's parcel, located immediately to the south of your property. This type of wetland requires a 50 foot buffer, much of which is believed to lie on your property. The site work you proposed in September, 1999 indicated the need to reduce the size of the required wetland buffer from 50 feet to 25 feet in width. Such a reduction in a wetland buffer is processed via a Special Permission application, which you submitted on December 15th. However, given the change in your proposal, a reduction in the wetland buffer will not be needed at .this time. We have closed your Special Permission file and have enclosed a refund of your application fee in the amount of $200.00. Further Actions Please be advised that the previous permits issued to you for construction of your home and associated site work are now officially closed. No additional work will be authorized under either of those permits. Accordingly, you should be aware of the following basic requirements if, in the future, you decide to further develop your property: 6300 Southcenter Boulevard, Suite #100 • Tukwila, Washington 98188 • Phone: 206 - 431 -3670 • Fax: 206 - 431 -3665 Jerry Knudson December 29, 2000 E99 -0029 (SEPA) L2000 -081 (Special Permission) Page 2 1. As stated above, under SEPA, there is a 500 cubic yard threshold for the import or export of material. We believe that you have already imported 500 total cubic yards of material to your site under previous permits. For example, under Land Altering Permit P93 -0055 you were authorized to import 470 cubic yards of material. Therefore, you may not import or export any additional material on the site without first obtaining a SEPA Determination. 2. Any proposal involving the removal, deposit or displacement of more than 50 cubic yards of material will require a Land Altering permit. This also includes the stockpiling of topsoil, peat, bark and similar materials and /or the clearing of areas larger than 5,000 square feet. 3. No work may occur inside the 50 foot wetland buffer. Any proposal requesting a reduction in this buffer (to no more than 25 feet) must be processed under a Special Permission application.

This plan is intended to protect and enhance the functions of a Type 2 wetland that is located immediately off -site to the south of your property. Although Type 2 wetlands in the City of Tukwila generally require a standard 50 -foot buffer, this buffer can be reduced by as much as 50% with implementation of a buffer enhancement plan (TMC 18.45.040.C.4). Due to the degraded condition of the existing buffer, the proposed project requests that the standard 50 -foot buffer be reduced to 25 feet. It is our opinion that implementation of the Buffer Enhancement Plan depicted on Figure 1 should increase'the functions of the wetland and will not result in direct or indirect short-term or long -term impacts to the wetland. Enhancement of the buffer will consist primarily of removing the existing non - native weeds and grasses and replanting the area with a variety of native trees and shrubs. Implementation of the buffer enhanctement plan should increase the plant species and structural diversity, thereby increasing the habitat value of the wetland. The native plantings will also protect the wetland by providing a physical and visual • screen. The following elements will be incorporated into the buffer enhancement plan: . CONSTRUCTION MANAGEMENT Prior to commencement of any work by contractors in the enhancement area, the construction limits will be staked and any existing.vegetation to be saved will be clearly marked. A.pre- construction meeting will be held at the site to review and discuss all aspects of the project with the selected contractor.

MONITORING METHODOLOGY The monitoring program will be conducted twice a year for a period of three years, with annual reports submitted to the City of Tukwila. Vegetation Permanent vegetation sampling points or transects will be established at selected locations within the enhancement area to incorporate all of the representative plant communities. The same monitoring locations will be re- visited each year with a record kept of all plant species found. Vegetation will be recorded on the basis of relative percent cover of the dominant species within the vegetative strata. All monitoring will be conducted by a qualified consultant. z re w 6 O 0 COO. w =. J w0 g< • a �w z= ZO w w U � o ff' Photo- points will be established from which photographs will be taken throughout the monitoring period. These photographs will document general appearance and i 0 progress in plant community establishment in the enhancement area. Review of the o photos over time will provide a semi - quantitative representation of success of the w z, planting plan. S o � Monitoring and photo -point locations will be shown and described in the first monitoring report. Wildlife Wildlife species that are readily observable (either by direct or indirect means) will be identified and recorded in the enhancement area. Direct observations include actual sightings, while indirect observations include tracks, scat, nests, song, or other indicative signs. Water Quality and Hydrology, During each monitoring event, an assessment will be made of the water regime within the enhancement area to ensure that proper hydrological conditions exist. General observations will be made of the extent and depth of soil saturation or inundation. Water quality will be assessed qualitatively, unless it is evident there is a serious. problem. In such an event, water quality samples will be taken and analyzed in a laboratory for suspected parameters. Qualitative assessments of water quality include: A.0.?il:et2F'cu."

RECEIVED CITY OF PERMIT CENTER SUCCESS CRITERIA Success of plant establishment within the enhancement area will be evaluated on the basis of both percent survival and percent cover of desirable species. Undesirable species include exotic and invasive species such as Scot's broom, Himalayan and evergreen blackberry, reed canarygrass, morning glory, and Japanese knotweed. For the planted trees and shrubs, success will be based on at least an 85% survival rate, or at least 50% cover of equivalent recolonized native species, by the end of the three -year monitoring period. • Exotic and invasive plant species will be maintained at levels below 20% total cover. Removal of these species will occur immediately following the monitoring event in which they surpass the above maximum coverage. Removal will occur by hand whenever possible. MAINTENANCE (M) AND CONTINGENCY (C) Established performance standards for the project will be compared to the " monitoring results in order to judge the success of the'enhancement project: " Contingency will include the items listed below and would be implemented if these performance standards are not met. Maintenance and remedial action on the site will be implemented immediately upon completion of the monitoring event (unless • otherwise specifically indicated below). • replace dead plants with the same species or a substitute species that meets the goal of the plan (C) • • re -plant areas after reason for failure has been identified (e.g., moisture regime, poor plant stock, disease, shade /sun conditions, wildlife damage, etc.) (C) • • remove /control weedy or exotic invasive plants by manual or chemical means approved by City of Tukwila. Use of herbicides or pesticides within the enhancement area would only be implemented if other measures failed or were considered unlikely to be successful (C & M) • after consulting with City staff - minor excavation, as needed, to correct alterations of surface drainage patterns (C) • clean -up trash and other debris (M) • selectively prune woody plants as necessary (e.g., thinning and removal of diseased portions of trees /shrubs) (M) z re w 6 J0 00 ND Ill J H w0 2 �Q co =a �w Z �. z0 w 2 O i• n-.

'Pr1LA PERMIT Cr;NTER RE: Your letter 4 December, 2000, referencing your 18 October 2000 letter , outlining additional information required. Attn: Deborah Ritter 1. Special Permission Application for a Wetland Buffer Reduction: Items a,b,c,d, & e are included 2 Revisions to SEPA checklist: A revised checklist is submitted with this application. The checklist is applicable to the request for a reduction in wetland buffer width from 50' to 25'. 3. Application for Land Altering Permit: Coordination with your Public Works Department has produced a complete set of existing As -built plans of the subject site. Including all Tax lot #s referenced to in the SEPA check list. This research has reveled an existing storm sewer line on the South property line with City of Tukwila marking stakes that does not have a recorded easement. The City should indicate the legality of this line and endeavor to properly record it. This may be contributing to the Wetlands as a manmade condition illegally constructed. Deadline As I commented previously, you did not sent me the copy of the 18 Oct letter until 4 Dec 2000. In the 18 Oct meeting it was agreed that Mr. Knudson could complete any grading and landscaping with respect to his residence and the parcel it occupies. A legal permit was issued by the City for the land altering permit on the parcel to the South ( #1157200394) in 1993, Permit # P93 -0055. Field research indicates that this original fill is in the same location as permitted. The additional fill material placed in this area was to be used as topsoil for Mr. Knudson's residence when it was issued a stopwork order in 5/99. This topsoil material has since be spread out over the permitted area and has established some vegetation growth to prevent erosion. In my discussions with Public Works it would appear that the best course of action would be not to disturb the existing vegetation and add straw mulch over the sparse area lacking a good growth of ground cover.
