FIELD REVIEW AND JURISDICTIONAL SUMMARY DATE: 24 September 1993 APPLICANT: City of Renton (Glacier Park Company) REFERENCE/FILE NUMBER: 91-4-00149 and 91-4-00099 RELATED FILE NUMBERS: 91-4-00095, 91-4-00096, 91-4-00097, 91-4-00098 (Glacier Park) ; 91-4-00062 (Intrawest Corporation) ; 91-4-00212 (Pace Corporation) ; 92- 4-00019 (Home Club Corporation) . PROJECT NAME: City of Renton Mitigation Banking WETLAND CONSULTANT: Parametrix, Inc., Tracy McKenzie LOCATION (Topog, S,T,R, City, County, drainage) : Mitigation Bank Site 1 is located north of Southwest 33rd Street and west of Oakesdale Avenue; Mitigation Site Bank 2 is located south of SW 34th Street, east of oakesdale Avenue SW and northwest of SW 39th Street. Both sites are in Section 25, Township 23 North, Range 4 East, Renton, Washington. PROJECT PURPOSE/DESCRIPTION & BACKGROUND: Nationwide Permit 26 was issued for all the referenced files (except 91-4-00149, Mitigation Site 1, which was issued oF a wetland confirmation only) . Nationwide Permit 26 was issued only for Lot 3 A POW" E . "ap`proX�ma[eZy-5..6� acres, of application number 91-4-00099 ri 3F"HTOc Ow referred to as Mitigation Bank Site 2, is a total of IS_-Jr5 acres) . The Corps issued a confirmation of the wetland delineation for the entire site. Mitigation Site 1 is approximately 31 acres in size. The city of Renton, negotiated and executed an agreement with the Glacier Park Company. The agreement allowed Glacier Park approximately 5.33 acres of wetland fill on their properties (not to exceed more than one acre/per property, as conditioned by NWP 26) in exchange for approximately 46 acres of nearby Ero ert ? owned by Glacier Park (which contains a total of a p � '�' approximately 2.i� acres of 71? wetlands; a roximately 18.78 acres of wetlands were confirmed for Mitigation Site 1 and approxima a 4 .83 acres of wetlands were confirmed for Mitigation Site 2) . Originally, the city of Renton, was going to require on-site mitigation for filling any wetlands on each of the referenced sites. However, in lieu of piecemeal mitigation, Renton executed the Mitigation Bank Site exchange so that more contiguous and comprehensive mitigation could occur in the area in hopes of restoring some of the lost functions and values associated with the hundreds of acres of fill placement in this area in the 1970's . Our wetland confirmation letter for application 91-4-00149 to the Glacier Park Company for Mitigation Hank Site 1 (which is now owned by city of Renton) did not issue a jurisdictional determination for the subject site. The letter, dated 28 February 1992 (enclosed) , states • [w]e have not determined permit requirements. When you have a specific development plan, you may reapply and we will determine requirements at that Cime. " ? "M►1y fa-fESS40 AT 9P.,00.14,K is 13aU47 &4«0 0W.

Therefore, confirming the delineation based on this report did not lock the Corps into a jurisdictional determination for the remainder of the property (Lots 1 and 2) , and NWP 26 for Lot 3 was specifically for that Lot, not for the zest of the parcel. A letter dated 25 August 1993 was received from the city of Renton requesting the Corps complete the jurisdictional determination (JD) regarding the adjacency status of the wetlands within the parcels. The city of Renton has requested a JD because the results of the JD will assist the City to move forward with developing a comprehensive mitigation program that may include mitigation banking for some wetland impacts within the Black River drainage basin. The City also stated that the results will be used by the project team and the City to develop site specific plans to convert the existing uplands on the parcels to wetlands and potentially restore the existing wetlands. In addition, the City and consultant team requested written guidance ont he type and extent of permitting and regulatory requirements associated with converting the uplands to wetlands and restoring the existing wetlands on these parcels (i.e. the difference between requirements associated with an individual 404 permit versus nationwide permit) . SITE DESCRIPTION, NWI: See attached, original MFR's and Corps letters for the respective sites , (Enclosure 1 for Mitigation Bank Site 1, Enclosure 2 for Mitigation Bank Site 2) The NWI showed no wetlands within Mitigation Bank Site 2 and identified on wetland, a palustrine, scrub-shrub, seasonally flooded community in Mitigation Bank Site 1. This wetland included Wetland M on site I. SITE VISIT (Date/attendees) : 14 September 1993 . Gail Terzi and T.J. Stetz from the Corps met with Tracy McKenzie from Parametrix and Scott Woodbury, and Mary Lynn Myer from the city of Renton on site. The purpose of the site visit was to determine jurisdictional parameters in terms of adjacency. WETLAND REPORT (Yes-Date/No) : Yes, dated 16 November 1991 for Mitigation bank Site 2 and 3 December 1991 for Mitigation Bank Site 1. Both reports were prepared by David Evans and Associates, Inc. CONFIRM DELINEATION (Yes/No) : Yes. For Mitigation Bank Site 1 the wetland delineation was confirmed by Corps letter dated 28 February 1993 and for Mitigation Bank Site 2 the wetland boundaries were confirmed by Corps letter dated 20 April 1992 . For more information refer to wetland reports referenced above. JURISDICTIONAL DETERMINATION AND DISCUSSION (Isolated-Migratory Bird Use, Above Headwaters, Adjacency, IP or NWP) : The wetlands on both the mitigation banking sites are adjacent to Springbrook Creek, a waterway with a mean annual flow greater than 5 efs. (see Enclosure 3) . Mitigation Bank Site 1 contains wetlands which are continuous with a large wetland parcel owned by the city of Renton, immediately adjacent to Springbrook Creek. The original MFR for this site contained some erroneous information. The information in this MFR supersedes that presented in the original MFR (see enclosure 1) . The original MFR stated (in discussion of jurisdictional determination section) ', [tlhe wetlands on this project site consist of some perched, isolated depressions, with some wetlands adjacent to the man-made drainage ditch running along the western boundary of the property and the more NGV-10-93 WED 10:07 PARAMETRIX FAX NO, 206 889 8808 P, 04/15 -3- natural, prolific and diverse forested wetland communities scattered throughout the site but most significantly on the northwest portion of the site. The drainage ditch along the western edge of the site appears to be connected with an open water wetland to the southeast of the site and from there to Springbrook Creek, which at that portion is above the headwaters. The wetlands on the site do not lie within the 100-year floodplain of Springbrook Creek. The Corps of Engineers can take jurisdiction on these wetlands based on their possible use by migratory waterfowl. " The information about the headwaters of Springbrook Creek is incorrect. This information was obtained from the city of Renton at the time and was not independently verified. The mean annual flow of Springbrook Creek has been defined by the Washington State Department of Ecology shoreline designation for the area and is 20 cfs to SW 43rd Street (this is where the 20 cfs designation for shoreline permitting ends) . This cfs data includes the project vicinity as described in this MFR. Therefore, the sites are well below the headwaters (5 cfs) of Springbrook Creek. This information was verified with the City of Renton on 4 October 1993. In addition, the drainage ditch is culverted across a right- of-way road to the east and are contiguous with wetlands owned by the city of Renton and adjacent to Springbrook Creek. This area contained quite a bit of standing water during our most recent site visit. It is likely that these wetlands are flooded by high waters overbanking Springbrook on a regular and periodic basis. wwafi F(40. lS A60LIr 7Ht 9rtA^VS nN SITE 2? W0111F AOWr fZ11-1.

Bellevue, Washington 98005-3553 PROJECT DESCRIPTION: The applicant proposes to construct wetlands by excavation and removal of prior fill and using restoration techniques for the purpose of a future wetland mitigation bank. Disturbance to the existing wetlands is expected. The applicant has requested a wetland delineation confirmation on this project, since a final plan for the mitigation site has not been developed to date. PROJECT LOCATION (S/T/R. City, County, drainage) : The project (Orillia Parcel s#14) is located north of Southwest 33rd Street and West of Oakesdale Avenue Southwest in Section 25, Township 23 North, Range 4 East, Renton, King County, Washington. SITE VISIT: Gail Terzi and Susan Glenn inspected the site on February 5 , 1992. Tom Duebendorfer from David Evans met us on site. SITE DESCRIPTION (Topography, etc, ) : The total acreage for the site is approximately 31 acres and contains approximately 19 acres of wetlands (Exhibit A) . The site is a composite of recently disturbed and relatively undisturbed areas. Approximately a third of the site was legally filled about 20 years ago. The more recently disturbed areas were either cleared or cleared and filled. The topography is generally flat, with the filled areas being somewhat elevated in relation to the undisturbed areas ; one area, about an acre in size, has about a 4-foot high mound of fill material. A 6-foot wide drainage *channel runs north-south along the western boundary of the site The site is zoned for industrial use and is bordered by developed commercial/industrial lands along the eastern half of the southern boundary. Undeveloped commercial/industrial lands lie adjacent to the western half of the southern boundary and to the eastern and western boundaries . The lands adjacent to the north and to the northeast are rural , forested and undeveloped and contain protected wetlands. The undisturbed part of the 31 acres consists of grassland, shrubland, and woodland areas.

CONFIRM DELINEATION (YES/NO) : Yes. INDICATORS (Vegetation, soils, hydrology-what is call based on?) : Total area of wetlands identified within the boundaries of the site is 18.78 acres. The wetlands range from 0.14 to 17.91 acres in size. Two of the identified wetlands would be classified as palustrine, scrub-shrub wetlands. The remaining wetland, the largest on the site, would be classified as a mosaic of palustrine wetland classes: including emergent marsh, scrub-shrub, and forested. All three wetlands are seasonally flooded. During our site visit the wetland areas were either ponded or inundated and the soils in the natural areas were clearly hydric, with evidence of oxidation and Munsell Chart readings at 10 inches of approximately 10 YR 3/1-4/1 with medium and distinct mottling. These soils are listed as mostly Woodinville silt loam with a small area of Puget silty clay loam. The- texture of these wetland soils were a fine sandy loam. The wetland soils in disturbed areas of the site were clearly gravelly fill material which were at times many feet thick. The disturbed areas were dominated by reed canary grass in wetland areas and Himalayan blackberry on the upland portions. The largest of the wetlands were contained to the northwestern part of the site and was dominated by mature black cottonwood, willows,dogwood, with an herbaceous layer of buttercup, soft rush and horsetails, A complete list of plants is provided for in the enclosed wetland report. DISCUSSION OF JURISDICTIONAL DETERMINATION (Isolated, migratory birds , above headwaters , adjacent. Include calculation of CFS , etc. ) : The wetlands on this project site consist of some perched, isolated depressions, with some wetlands adjacent to the man-made drainage ditch running along the western boundary of the property and the more natural, prolific and diverse forested wetland communities scattered throughout the site but most significantly on the northwest portion of the site. The drainage ditch along the Western , roc. edge of the site appears to be connected with an open water wetland to the southeast of the site and from there to Springbrook Creek, which at that portion is above the headwaters. The wetlands on the site do not lie within the 100-year floodplain of Springbrook Creek. The Corps of Engineers can take jurisdiction on these wetlands based on their possible use by migratory waterfowl. NWP OR IP (Discuss reasons) : Further analysis would be required before this .x determination was made. The applicant is requesting a confirmation of the wetland delineation, which was confirmed on the site inspection. The wetland delineation report appears accurate and complete. An adjacency determination would be needed before any work could begin on this site, The site is situated in the Green River floodplain.

SEATTLE, WASHINGTON 98124-2255 •[�l�TO /rr[NTION Of APR nR 2 6 19M Regulatory Branch (/ SUBJECT: Delineations and Adjacency Determinations for Jurisdictional Waters of the U.S. In April of 1988 Corps headquarters provided guidance to all Corps Districts allowing consultants to make preliminary wetland delineations for applicants applying for Section 404 permits . For the most part, delineations done by consultants have been found to be acceptable by the Seattle District Regulatory Branch with one exception - the issue of wetland adjacency/isolation determinations. We have noted many instances in the .last several years where consultants have, in the context of a wetland delineation report, advised their clients on wetland adjacency/isolation. Many of these determinations have been erroneous. An erroneous adjacency/isolation determination impacts applicants because a different permitting process must be pursued. I am requesting that consultants do not make adjacency/isolation determinations in their delineation reports. In some cases consultants have even advised their clients that a nationwide permit applies to the jurisdictional activity. In a few instances applicants have filled waters of the U.S. based on that erroneous advice. These situations have resulted in enforcement actions by the Corps. We advise you to tell your clients that jurisdiction, including adjacency, is determined by the Corps. Please advise your clients that written confirmation and authorization from the Corps is highly recommended to be certain that their project qualifies for a nationwide permit. Any work done prior to the Corps' jurisdictional call is at their own risk. I would also like to recommend that when you conduct a delineation suitable for submittal to the Corps, you delineate all waters on the site, such as lakes, rivers, creeks, and ditches. Show the ordinary high water mark or mean higher high water mark, as appropriate. The Corps regulates all waters of the U.S. and thus, in addition to wetlands and other special aquatic sites (such as mudflats and vegetated shallows) , preliminary drawings should show all waterbodies on the site, whether natural or manmade. The Corps will then ascertain which waters are jurisdictional. The District Engineer retains the authority to make all final jurisdictional determinations (consistent with all agreements with the Environmental Protection Agency) , Sincerely, THOMAS F.

All of these parcels are currently owned or optioned to sell by Glacier Park Company and are within the same geographical area in the city of Renton termed the 110rillia Industrial Park." Because of the proximity of these properties to one another, a decision concerning the applicability of Nationwide Permit 26 to the subject properties is very complex. Before a decision can be made, it is important for the Corps to obtain information about how the Glacier Park Company and the City of Renton viewed the subject area historically. How Nationwide Permit 26 applies to these applications is dependent on the concept of "single and complete project." Several major policy decisions have been made in the recent past based on information pertaining to a project's "single and complete" determination. The decision for the subject parcels must be consistent with Corps determinations on these past applications. Because of the complexities involved in the "single and complete" project decision, I am not in a position to guarantee that a decision will be made by early May. However, I do realize that this .is the scheduled time for some of the referenced properties to be auctioned off by the Glacier Park Company, and I will do everything possible to expedite the decisionmaking process. -2- If you have any questions, please contact me at (206) 764-3690.

Club Corporation 92-4-00019 We have reviewed the Wetland Mitigation Bank Conceptual Plan for the Glacier Park Company and the City of Renton Landholdings forwarded to this office and dated February 21, 1992. It appears that Mitigation Bank Site 1 contains approximately 18 . 78 acres of wetlands and Mitigation Bank Site 2 contains approximately 6.77 acres of wetlands for a total of approximately 25.6 acres' of wetlands and approximately 19 . 35 acres of uplands existing in the mitigation banks. Of this total, the report states that approximately 8 .03 acres of wetlands on the bank sites are enhanceable. The conceptual mitigation plan indicates that these mitigation banks will include preserved forested wetlands, enhanced wetlands, open water, emergent marsh, shrub buffer, created scrub-shrub wetland, created open water and emergent plantings . The report does not contain any information relative to creation of wetlands nor does it contain any information pertaining to the referenced applications and the participation of these separate nationwide permittee's in the mitigation scenario. Although we have been informed that the city of Renton is requiring these separate parcels to participate in the mitigation banks, we do not have any details supporting this. Enclosed is a location map listing the 8 separate nationwide permits issued for the individual parcels as shown on the map. This enclosure also includes individual and total wetland fill for the 8 parcels. Our records indicate that the 8 separate nationwide permits will allow approximately 6.57 acres of total fill into wetlands. Please submit additional information as to which parcels will be participating in the mitigation bank, the ratios you expect when participating in the bank and if the ratios are expected to be different for creation versus enhancement of wetlands. Please submit any finalized mitigation bank drawings and/or established banking parameters for the different applicants and parcels referenced above. -2- We are requesting this information because currently there is no way for . the Corps of Engineers to track applicants and/or permittees utilizing the mitigation bank. In the future we may require an applicant to submit mitigation plans for fill activity under Nationwide Permit No. 26 or under the individual permit process and we will need information and updates as to which mitigation banks are accessible for use and how much wetland creation and/or enhancement is still available at these banks . We need to ensure that duplicate banking does not occur at these sites and to ensure appropriate ratios are obtained for filled wetlands versus created and/or enhanced wetlands on the mitigation bank sites. We would also like to reemphasize and clarify our position on the Nationwide No. 26 permitting of the above referenced applications . Our decision to issue separate nationwide permits was based solely on our determination, that the separate parcels were not a "single and complete" project. Our decision was autonomous from the mitigation bank concept and remains as such. The Corps, in .this case, did not "trade the right to fill some marginal wetlands in exchange for preserving significant wetlands elsewhere" . This erroneous assumption has been emphasized in several newspaper articles in the past two months. The articles also implied that the Corps "cut a deal " with the city of Renton for the separate nationwide permits. The basis of our determination was established through rigorous research and the gathering of background information pertinent to our decision on the single and complete aspect of the proposals. We would like to make it clear that the Corps does not "cut deals" for mitigation banking proposals and that we look at each application on a case by case basis. Any clarification that the. city of Renton could provide to the media and the public on this aspect would be greatly appreciated. Please submit the requested information as soon as possible so we can update our files to contain the pertinent information on the mitigation banking. Also, please be aware that the Corps has confirmed the wetland delineation for the Mitigation-Bank 1 site (Corps Application No. 91-4-00149) , by letter dated February 28, 1992. Parties participating in the mitigation bank may need to get a permit from the Corps to perform some of the work, such as wetlands enhancement, on this site.

Padvorac: We concur with the revised wetlands boundary delineation made by Raedeke Associates for your property in Renton, Washington. The delineation in Raedeke'a November 7. 1988. report is acceptable as revised by our November 29. 1988. site visit.. Those revisions are shown on the revised map submitted with your February 16. 1989 letter. i If you intend to place fill into those wetlands. you will need to compute the acreage of wetlands existing and proposed to be filled. We consider the wetlands on the property to be isolated. Therefore, filling into those wetlands may be subject to the requirements of 1�ationwide Permit 26. described j below. Department of the Army regulations dated November 13. 1986, authorize certain activities under nationwide permits. Paragraph 330.5 (a) (26) of these regulations authorizes discharges of dredged or fill material into nontidal rivers, streams, and their lakes and impoundments, including adjacent wetlands, that are located above the headwaters (where the average annual flow is less than 5 cubic feet per second) . Similar lischarges are also allowed into other nontidal waters of the United States :hat are not part of a surface tributary system to interstate waters or navi.galie waters of the United States (i.e. . isolated waters) . The discharge area must be less than 1 acre. Thus, you may fill up to 1 acre of wetlands )n the site, provided you comply with the enclosed conditions. However, filling between 1 and 10 acres of these wetlands would require prior coordination between us and the Federal and state resource agencies. If you plan to fill 1 or more acres of wetlands on the site, you must notify us in writing. We would then request comments on your project from the appropriate agencies and subsequently decide to either allow the fill under conditions of Nationwide Permit 26 or to require an indi- vidual permit for the work. This "pre-discharge notification procedure" takes 20 days. At the Renton site we have perL,iit requirements only for the place.rient of fill in the wetlanda which havo been identiiled. You Iuay proceed with construction activities on nonwetland areas of the rite without any involve- ment from us. Wetlands are dynamic ecosystems and are Inighly subject to change. The Federal regulations governing development are also subject to change. This determination may be considered valid for only 1 year. Nothing in this letter shall ue construed as excusing you frow compliance with other Federal. state, and lucai utatute.s, ordinances, and regulations which may pertain to this work.

The parcel was vacant and was zoned "Manufacturing Park". The site is located on Southwest 27th Street, west of Springbrook Creek. The 99,544 square foot structure includes 57,000 square feet of space devoted to manufacturing uses, 30,544 square feet devoted to storage and 12,000 square feet devoted to office space. The site is in the 100 year flood plain, requiring special mitigation measures. It also hosts wetlands. Fill had been placed on the site previously; additional fill of approximately .75 acre was necessary to accommodate the development. The project generates approximately 100 passenger car trips and 11 truck trips per day. B ECF;SA;SSM;SP-051-91 Seattle Times A currently vacant 34 acre (two parcel) site is to be developed with a 433,000 square foot newspaper printing/distribution facility, a 13,000 square foot Vehicle Maintenance Facility, and a power substation to support the production center on the western 25 acre parcel (Phase 1); and an Administration, Operations And Financial Office Headquarters, approximately 250,000 square feet on the eastern nine acre parcel (Phase II). User amenities are proposed including passive recreational areas, and surface/enclosed parking facilities. The project site is located at the Northeast corner of Oakesdale Avenue and Southwest 34th Street. The two parcels were bisected by Springbrook Creek, necessitating a Substantial Shoreline Management Permit. The site included approximately 3.50 acres of wetland, of which .99 acres were filled (under a Special Permit); Wetlands preservation, replacement, and enhancement have been undertaken based upon DOE Guidelines. Traffic from the project is anticipated to total approximately 3,940 average trips per day. This breaks down into approximately 960 trips by employees of the production facility, approximately 280 truck trips (deliveries of raw materials and distribution of the finished newspaper) from that facility, and approximately 2,700 trips per day generated by the office building occupancies. C ECF;SA-068-90 Southgate Office Plaza Limited Partnership Site plan approval was granted for Phase II which included two five-story office buildings including parking, landscaping and recreational amenities on a 20.06 acre site. Previous land use consisted of a three-story office building, landscaping and parking. The project site is zoned for Office Park use and is located at 2100 Lind Avenue. Approximately 35 percent of the site, including the central plaza, will be landscaped or retained in wetlands or natural plant materials. The site contains approximately 2.7 acres of wetlands. The applicant will be filling approximately 0.97 acres of small wetland areas while enhancing the remaining larger, contiguous areas. The preserved wetlands are concentrated along the northern and western perimeter of the site. The applicant proposes no development within the wetland areas and within an additional 25 foot setback from the wetlands. The project will generate approximately 5,420 trips per day. D ECF;SA 118-89 Austin Company An office park complex, including two four-story office buildings (271,200 total square feet) and attendant amenities (pedestrian plaza, 1185 parking spaces, landscaping) to be located on a vacant 14.47 acre parcel zoned Office Park.

The project site is located North of Southwest 41 st Street and between Lind Avenue and East Valley Highway. Pace will generate approximately 5,150 average daily traffic trips. G ECF;SA 030-89 Austin Company (GSA/FAA Building) A five story/199,000 square foot (177,000 square feet of leasable space) office building on an 8.8 acre parcel in an Office Park (OP) zone. The site is located at Lind Avenue and Southwest 16th Street. The building has been leased to GSA for a ten year period and GSA will utilize approximately 155,000 square feet for office space and the remaining 16,000 square feet for warehousing. A Puget Power substation is also located on the site. The property is in an area which has a number of identified wetlands, however, the subject property itself has been inventoried by certified geological engineers and determined not to include wetlands. Wetland grasses on site are reported to have been imported with fill previously placed on the site from the Duwamish River. The project generates an estimated 2845 daily vehicle trips. H SA 112-89 Blume Company The applicant, (Bruce Blume and Company), obtained site plan approval for a 285,835 square foot warehouse/office complex, including two structures, parking and service areas, landscaping and recreational amenities. There was a wetland on the site—a .99 acre portion of which was filled and the remainder enhanced with native vegetion. The 16 acre project site was vacant and was zoned for manufacturing park use. The project site is located at 601 Monster Road Southwest. The project was estimated to generate 70-86 vehicular trips per day. I SA 039-90 Sconzo Associates A 108,000 square foot addition to an existing 74,000 square foot industrial complex including manufacturing, office and warehousing activities was approved recently. The addition was on a vacant approximately 4.3 acre parcel immediately east of the approximately 3.4 acre parcel on which the existing development was located. The proposed manufacturing/warehousing/office development was located on a site which has wetland areas. Some fill had been placed on the site. The applicant proposed additional filling, of +/- .66 acre in the wetland areas. Wetlands enhancement was undertaken outside site boundaries on a nearby site not within the 100 year flood plain. The project site is located at 301 Southwest 27th Street. The project generates an estimated 22 auto in/out trips per day, 1 truck in, 4 trucks out per day, over over two shifts 7am-12pm J ECF;RVMP;082-90 Rabanco The applicant (Anmarco) is seeking management permit for a recycling and transfer operation employing manual and mechanical processes to remove recyclable material from construction, demolition, and landclearing debris. The project would consist of several structures. These structures include a main processing and recycling building (covering approximately 60,000 square feet), two smaller buildings (each covering 1,500 square feet) for equipment repair and maintenance, and employee/administrative services, and two container storage areas of approximately 5,000 to 7,000 square feet each. The tallest portion of the main structure would be approximately 50 feet above the finish grade at the front (east side) of the building. The project is located on a 13.5 acre site in the northwest corner of the City on the west side of 68th Avenue South (Monster Road). The project site is zoned Light Industrial District (L-1). A maximum of 900 truck and 60 automobile trips would be generated per day with 90 - 95% of the trucks bound for the site arriving by way of 1-405 to the south. Access would be by way of Steel-Monster Road, which borders the east edge of the site. K SA;SM;SP 040-91 Metro The applicant sought in 1991 to obtain: a) Site Plan Approval and Shoreline Master Program Substantial Development Permit to expand facilities at the existing Metro Waste Water Treatment Plant thus increasing secondary treatment capacity from 72 million gallons per day (mgd) to 108 mgd; b) Special Permit for grading (Excavation, Fill and Grading) and Routine Vegetation Management Permit. The approved expansion will occur in three phases: Phase A (1991-1993): Site Preparation (vegetation clearing, excavation fill, grading and site de-watering) and Perimeter Landscaping; Phase B (1993-1996): Facility Construction; and Phase C (1996): Interior Landscaping and Site Clean-up. The project site is located at 1200 Monster Road Southwest. There are two small wetland areas, of approximately 2 acres, at the northern most portion of the site, which will not be affected by the project. These wetland areas will be protected during construction and project operation by a 25 foot wide buffer strip and a security fence. Mitigations for this project includes approximately 3.5 million dollars for open space/wetlands acquisition and 2.5 million dollars for a fire station. Other mitigation includes nearly 4.6 million dollars in off-site capitol improvements. The site will generate an estimated 564 p-er day. L ECF;SA;SP 030-91 Puget Western Business Park The applicant sought site plan approval to develop a 34.3 acres site for seven office/warehouse buildings. The buildings will be one to two stories in height. Only 22 acres of the site will be developed, the remainder will be retained in its natural state. The project site is located at the Northeast corner of Lind Avenue Southwest and Southwest 27th Street. There are approximately 12 acres of wetlands on the project site. The applicant has recieved approval from the Army Corps of Engineers to fill .99 acre of wetland area. The project will generate an estimated 4,664 average weekday trips.

BACKGROUND On May 18, 1992 the City executed a Wetland Mitigation Banking Agreement with the Glacier Park Company, as authorized by the City Council. Under this agreement, the City was given two properties totaling 45 acres in exchange for permits to fill up to 0.99 acre of low quality wetlands on each of six other Glacier Park parcels. The City of Renton also agreed to pay for and complete on the mitigation bank sites, any mitigation for impacts on the Glacier Park parcels required by the City of Renton Wetlands Management Ordinance, although no mitigation for the fill was required by the Army Corps of Engineers. After fulfilling the requirements of the Glacier Park agreement, the City will use the remaining available acreage on the mitigation sites to mitigate for wetland impacts from other private development and/or public projects. B. ACTIVITIES COMPLETED TO-DATE In July 1993 the City executed a contract with Parametrix, Inc., to establish the technical and programmatic framework for the conversion of existing uplands on the City mitigation bank site to wetlands, and for the use of the created wetlands as compensation for other wetland impacts within the watershed, including the impacts permitted by the City under agreement to Glacier Park (up to 5.33 acres). Using information provided by the City on conditions within the watershed and on the wetland mitigation bank sites, combined with on-site visits and soil exploration, the consultant prepared exhibits for presentation in public meetings. The exhibits included: 1) existing conditions of the bank sites and surrounding area; 2) preliminary goals, objectives, and policies for the Wetland Mitigation Banking Program; 3) the regulatory permit process; and 4) comparison of advance and concurrent compensation of wetland impacts. Two public meetings were held in late October 1993 to invite comment on the proposed Wetland Mitigation Banking project from interested individuals, groups, property owners, and developers. General support of the project was expressed. Issues discussed focused around the scope of improvements, the potential for successful wetland creation, and the details on the implementation and operation of the bank. A subsequent meeting with regulatory agencies scheduled for early November 1993 had to be canceled because of a labor strike by City of Renton union employees. The decision was made to not reschedule the agency meeting until after a January 1994 meeting with the Army Corps of Engineers. C. REMAINING ACTIVITIES AND SCHEDULE Agency and public meetings.

Can public programs use the bank? 2. What are advantages to developer? 3. Is City going to fill the major wetlands just south of SW 27th Street? 4. Does Boeing own all of Longacres? What is the zoning surrounding sites and in area? 5. Does City own strip above bank site #1 (P-1 Channel)? 6. Have you measured elevation of water level in wetland south of 27th and east of Longacres and compared with groundwater on bank site #1? 7. Saw program on public TV. Wetland biologist says wetland creation not possible. How do you respond to that? 8. What is longest time period until created wetland established? What is its success? 9. What do you do with canary grass? 10. When do you call a mitigation a success so credit can be withdrawn? 11. How is bond handled? 12. What department in City is in charge of project? Who is responsible? One or more City Departments? 13. Has ESGRWP been resurrected? Will they coordinate with Kent? 14. Objective refers to maintain 100-year flood storage function of wetland. Is this FEMA or R. W. Beck study? 15. What is section on objectives addressing 1:1 ratio? 16. What about displacement of wildlife during establishment of wetlands? 40 - 50 years? 17. How are buffers addressed/incorporated? 18. Has Springbrook been altered? 19. Can Springbrook be incorporated/restored? 20. Will membrane cause stagnation? Will membrane use be limited? 21 . Are you on schedule for implementing P-1/Springbrook? 22. What about drainage of Panther Creek? Wetland Mitigation Bank Project Questions from Public Meeting of 10/20/93 Page 2 23. What kind of wetlands do you plan to create? 24. Suggest funding come in possibly 50% developer, 40% City, and 10% County. 25. Will you consider public participation in monitoring? Questions posed by City and consultant staff to meeting attendees with responses: 1. Any comments or questions on the conceptual renderings and on-site considerations? a) Should there be public access to the site? How much? Limited access. Confined to specific areas. Concerned that developer may try to utilize sites as amenity. Domestic animals should be restricted. Restrict to joggers. Should be meandering. b) What type of interpretive material would be useful? Include signs for: plant species; explanation of why wetland created; historical background; Indian heritage; signs should be restricted to one area. e) Are there any other features that should be included, such as trails, flood storage, and wildlife habitat? Raptor habitat. Possibly go for higher quality habitat on Site 1. 2. Should public and private users be equally eligible? Both should be allowed. May depend upon timing. 3. Should the City limit the size of wetlands that are eligible? Possibly exclude Category 1 wetlands. Want to see mitigation established before impact. Better to have smaller pilot projects (sending property impacts less than one acre).

Wetland Mitigation Bank Project October 21, 1993 Development Community Meeting Questions/Comments: 1. Developers want to know all the costs and have assurances of closure of responsibility in a reasonable amount of time. a. Ideal scenerio. Construct the site and identify all costs (no hidden costs) so that developer who meets eligibility pays cash and is done. b. Without actual costs set an upper limit on potential costs so that maximum potential liability is known. C. Limit the use of hold harmless and transfer of liability requirements so that the developer can see closure to his responsibility. d. Minimize the amount of time that a developer must be responsible. 2. Development community desires "user friendly" regulations that are not overly restrictive. a. Consider ordinance revisions. 1. Eliminate avoidance/minimize requirement for Category 3 wetlands. 2. Develop single payment scheme. 3. Consider fee-in-lieu program. 4. Allow impact before mitigation. - b. Reduce site plan approval time. C. Simple eligibility requirements with minimum of paper work and cost to determine eligibility. Developer typically not willing to sink money into a site unless a specific project is on line. Must be setup to realize some return for the expenditure in order to justify the costs. 3. Suggestions for funding program and increasing developer awareness and confidence in using bank sites for mitigation. a. Fund full bank site development using special assessment district or some sort of general tax and establish successful mitigation prior to issuing credit. Wetiand Mitigation Bank Project Questions from Public Meeting of 10/20/93 Page 2 b. Construct entire bank site 2 to mitigate for the 5.33 acre obligation and use excess acreage as pilot mitigation bank and demonstration to development community. C. Amenities, such as trails, should come from City, not developer, funds. Developer should be responsible for basic mitigation for the associated impact. d. The City should consider cost sharing with the developer for the mitigation partly because of the increase in tax base that may result 4. Other comments/questions. a. Will the program allow other types of credit, such as compensatory storage for filling the floodplain? b. When will a potential user be considered eligible? Following SEPA review, permit issuance, or at some other time? C. Will the program be first come, first serve, and how long will a user remain eligible once accepted? d. Public and private users should both be allowed. e. The program should not exclude greater than one acre impacts if all requirements are met . f. The program should not be limited to only Catagory 3 impacts. g. Corps has rarely issued permits. However, projects that have gone through the Corps process should be allowed to use the bank. h. General interest and support for the banking concept, but need to see more information. - I Questions for Discussion 6x-ra364L 'ij, Ji'73 ��r£t.Qfr�6.fr` c ., n�(. 1. Are there any comments or questions on the goals and objectives? 2. Do you have any ideas on how we can reduce the cost for use of the sites for mitigation? a. Volunteer plantings? Donated interpretive materials? Volunteer maintenance and monitoring? b. Cost sharing? 1) Percentage split of all costs by public and private? 2) City accept responsibity for all maintenance bonding and contingency costs, or for all of these costs in excess of a certain dollar value? c. Limit the impacts to Catagory 3 isolated wetlands less than one-acre so that permitting is simplied and implementation costs are less expensive? d. Simple eligibility requirements and reduced permit costs for eligible properties? 3. How should users be chosen? a. First-come-first serve, regardless of wetland size, function, and value? b. At what point should a user be considered eligible? 4. Should public and private users be equally eligible? 5. Should the City limits the size of wetlands that are eligible? 6. Is anyone interested? How can the program address your needs in order for you to consider the City mitigation sites as a viable option? 7. Site design questions. a. Should there be public access to the site? Trails? No trails? Perimeter trails? Extensive trails? b. What type of interpretive material would be useful? Displays illustrating the vegetative, wildlife, hydrologic and hydraulic, and geologic features to be observed? Descriptions of wetland value and function? Project objective? Historical background of Green River Valley and project sites? c. What other features should be included? Flood storage? For Springbrook Creek? For private and public development projects? Type of wildlife you would like to see use the site? Wildlife habitat features? Nest boxes? Snags? Wetland Mitigation Bank Project Attendees of 10/21/93 Public Meeting: Tim Puryear Jim Douma H.

BACKGROUND On May 18, 1992 the City executed a Wetland Mitigation Banking Agreement with the Glacier Park Company, as authorized by the City Council. Under this agreement, the City was given two properties totaling 45 acres in exchange for permits to fill up to 0.99 acre of low quality wetlands on each of six other Glacier Park parcels. The City of Renton also agreed to pay for and complete on the mitigation bank sites, any mitigation for impacts on the Glacier Park parcels required by the City of Renton Wetlands Management Ordinance, although no mitigation for the fill was required by the Army Corps of Engineers. After fulfilling the requirements of the Glacier Park agreement, the City will use the remaining available acreage on the mitigation sites to mitigate for wetland impacts from other private development and/or public projects. B. ACTIVITIES COMPLETED TO-DATE In July 1993 the City executed a contract with Parametrix, Inc., to establish the technical and programmatic framework for the conversion of existing uplands on the City mitigation bank site to wetlands, and for the use of the created wetlands as compensation for other wetland impacts within the watershed, including the impacts permitted by the City under agreement to Glacier Park (up to 5.33 acres). Using information provided by the City on conditions within the watershed and on the wetland mitigation bank sites, combined with on-site visits and soil exploration, the consultant prepared exhibits for presentation in public meetings. The exhibits included: 1) existing conditions of the bank sites and surrounding area; 2) preliminary goals, objectives, and policies for the Wetland Mitigation Banking Program; 3) the regulatory permit process; and 4) comparison of advance and concurrent compensation of wetland impacts. Two public meetings were held in late October 1993 to invite comment on the proposed Wetland Mitigation Banking project from interested individuals, groups, property owners, and developers. General support of the project was expressed. Issues discussed focused around the scope of improvements, the potential for successful wetland creation, and the details on the implementation and operation of the bank. A subsequent meeting with regulatory agencies scheduled for early November 1993 had to be canceled because of a labor strike by City of Renton union employees. The decision was made to not reschedule the agency meeting until after a January 1994 meeting with the Army Corps of Engineers. C. REMAINING ACTIVITIES AND SCHEDULE Agency and public meetings.
