I. PROJECT INFORMATION Project File Number: L15-0022 Applicant: Andrew Gross, for Washington State Department of Transportation Type of Permit Applied for: Tree Cutting Permit Project Description: Replacement of trees removed from I-405 storm water area Location: I-405 Off -ramp at Interurban Ave. S./Fort Dent Way Associated Files: None Comprehensive Plan Designation/Zoning District: II. BACKGROUND N/A — WSDOT right-of-way Adjacent to the off -ramp from southbound I-405 to Interurban Ave. South/Ft. Dent Way is a three tiered retaining wall structure containing stormwater facilities for the highway. The structure is located within Washington State Department of Transportation (WSDOT) right-of- way. This three tiered retaining wall structure is next to the Green River Trail. This retaining wall structure was constructed at the time (approximately 1993) when the off -ramp was reconstructed by WSDOT and landscaped with six evergreen trees upon completion of the off - ramp reconstruction.

Dent Way. A portion of one of the retaining walls was collapsing and there was significant undermining of a USGS gauging station located in the vicinity of the collapsing wall. WSDOT maintenance staff removed all of the vegetation from each of the three tiers and repaired the blocked storm water pipe. It appears that in addition to the six trees that were planted at the time the reconstruction was completed, volunteer evergreen trees had also seeded and become established. As can be seen from the photos below, the trees that were removed were quite large. CL Page 2 of 5 07/16/2015 10:02 AM H:\\L15-0022\WSDOT Staff Rpt.-NOD.docx July 16, 2015 L15-0022 WSDOT Tree Removal Staff Report and Notice of Decision Staff Discussion WSDOT has agreed to replace the six trees that were originally planted and shown on the landscaping plan when the on/off ramp was reconstructed. The site is located in the City's shoreline jurisdiction, therefore the tree regulations that govern are found in TMC 18.44.080. Any clearing of any vegetation in the shoreline requires a Tree Clearing Permit. Based on the tree replacement ratios found in TMC 18.44.180 B.4., a total of 36 trees would need to be planted to replace the trees that were removed. WSDOT has evaluated the site and proposes to plant five Excelsa Cedars trees at the edges to avoid interfering with the flow lines of the storm water system. The dimensions of this tree at maturity will not block roadway signage or grow into the bridge deck in the future. WSDOT will pay into the City's tree replacement fund for the remaining 31 trees. A landscaping plan has been provided as part of the permit application. III. DECISION SEPA Determination: The City's SEPA Responsible Official has previously determined that this application does not require a SEPA threshold determination because it is categorically exempt. Decision on Substantive Permit: The City Planning Supervisor has determined that the application for a Shoreline Tree Removal and Vegetation Clearing Permit does comply with applicable City and state code requirements and has approved that application, subject to any conditions which are set forth in the Decision below: 1. A total of thirty-six (36) replacement trees are required to be planted. Based on the landscaping plan submitted by WSDOT, five trees will be planted on site — the remaining trees will be compensated for by paying into the City's tree replacement fund. 2. Tree planting may be deferred to the fall to ensure plant survivability.

In an email dated April 22, 2015, Andrew Gross, the Regional Maintenance Environmental Coordinator, provided an estimate for replacement trees at $85.00/tree based on the average cost for an eight -ten foot Western red cedar or Douglas fir. Six trees were removed — based on their size, six replacement trees are required for each removed tree. Five trees (all Excelsa Cedars) will be planted at the site where the trees were removed. This leaves 31 replacement trees that cannot be planted at the site and therefore will be compensated at the agreed rate of $85.00 per tree. This fee goes into the City's tree replacement fund and will be used to plant trees in the shoreline as opportunities arise. In addition to the tree replacement payment, there is a fee of $110.25 for the shoreline tree removal permit (my April 22, 2015 letter to Andrew Gross incorrectly stated the fee is $100.25). The City's permit fees can be found here: http://www.tukwilawa.gov/dcd/LandUsePermitFees.pdf. You may make one payment to the City and the receipt will break out the tree replacement contribution from the permit fee. If you are paying by credit card, you can call Teri Svedahl, at 206-431-3670; if paying by check, please make the check out to the City of Tukwila. To summarize, the following are the monies owed to the City of Tukwila: Shoreline Tree Removal Permit Fee: $ 110.25 Replacement Tree Fee ($85/tree-31 trees to be replaced) $2,635.00 TOTAL $2,745.25 Please let me know if you have any questions.

I would assume the trees will be planted in the fall unless WSDOT is planning to water the trees during the summer? When you submit the check, please reference the file number for this project, which is A15-0022 — that way the money will be credited to the correct account. If you want to send the check to my attention, that would work as well, and I will make sure WSDOT is credited. I will send you a receipt via e-mail is that is acceptable.

Sent: Wednesday, May 13, 2015 1:47 PM To: Gross, Andrew Cc: Golden, Micheal; Durst, Gary Subject: I-405 SR 181 Replacement tree locations Andrew, 1 i I met Mike and Gary out on site this morning and we were able to identify 5 acceptable location on the edges of the stormwater BMP where tree plantings are possible. Because we can only plant trees on the edge of the site, and not within the flow lines of the BMP, I have had to select a tree with a narrow form. My goal is to match, as closely as we can, the character of the trees removed: evergreen natives. For these reasons I feel that the Excelsa cedar (Thuja plicata 'Excelsa') would be an appropriate choice; it grows to 35' height at maturity and attains a 10'-15' diameter so it won't block roadway signage or grow into the bridge deck in the future. I've attached a marked up plan sheet showing the approximate locations of the trees. The size and height of the trees at time of installation is listed below: Species Quantity Size Height Excelsa Cedar 5 #5 cont. 2' - 4' The benefit of planting the #5 container is that these trees will adapt and recover from the transplant shock much faster than a larger specimen. This means that the chance of survivability within the first few years will greatly be increased. Please let me know if I can provide any more information.

The trees were removed during the process of determining how to repair a storm water drainage issue at this off -ramp. A permit file number of L15-0022 has been assigned to this project. In an email dated April 22, 2015, you provided an estimate for replacement trees at $85.00 based on the average cost for an eight -ten foot Western red cedar or Douglas fir. Six trees were removed — based on their size, six replacement trees are required for each removed tree. You are still exploring whether any trees can be planted at the site — since WSDOT initially provided a landscape plan for this area when construction work was carried out at the off -ramp and planted six trees, I hope that it will be possible to replace some of the removed trees on -site. For any trees that are not planted at the off - ramp, WSDOT will pay into the City's tree replacement fund. In addition to the tree replacement payment, I don't believe we talked about the permit fee - there is a fee of $100.25 for the shoreline tree removal permit. I will attach the application — you only need to fill out the first page, and if there will be trees planted on site, specify the number and location. You may make one payment to the City and the receipt will break out the tree replacement contribution from the permit fee. If you are paying by credit card, you can call Teri Svedahl, at 206-431-3670; if paying by check, please make the check out to the City of Tukwila. Please let me know if you have any questions.

I have calculated what WSDOT believes it is responsible for mitigation. Please let me know if we are on the same page and we will move forward with a payment. Six planted conifers (within the 8"-20" dbh range) were cut down within the city of Tukwila's shoreline jurisdiction. Additional volunteer big leaf maples were also cut down but were located within the limits of the BMP. However, these trees were not counted in the calculation for the mitigation tree fund as they should have not been allowed to become established within the flow lines of the stormwater BMP. The original planting plan included 4 Douglas firs and 2 western red cedars. Using the city of Tukwila's Shoreline Tree removal requirements, WSDOT is responsible for the cost of 36 trees (6 trees for every cut tree). Based on tree prices provided by landscape and the calculation provided by the city, we would owe $85/tree x 36 = $3,060. The $85/tree is an average cost for a 8'-10' Western red cedar or Douglas -fir at 3 Pacific NW wholesale nurseries (cost were comparable between both species). I will have landscape take a look at the site next week with the maintenance crews to see if there are locations suitable for replanting a few conifers back on site. If so, that number will be reduced from 36 tree cost total provided. Sounds like we can bay by credit card. Is it possible to have a bill sent to the address below?

There is a USGS gauging station near there, so WSDOT and King County were notified. To investigate the damage, WSDOT took the trees out. Here is the initial assessment from PW staff: "You may already be aware of this but in my field review this afternoon near the Fort Dent/Interurban intersection I noted a retaining wall collapse and significant undermining of the USGS gauging station on the south edge of the Green River (SW corner of Ft. Dent and IU). If we haven't already alerted the appropriate contacts at DOT, King County Flood District, USACE and/or USGS we probably should do that. It looks like DOT may have a failed drainage system on the SW corner of the intersection and the runoff from the off ramp is running under the jersey barrier and taking a portion of the bridge abutment away as it makes its way down the slope to the river. It doesn't currently look like an imminent failure situation but with a couple more large winter storms without appropriate attention it could turn into a real problem." By the time I was able to get out to look at the site, the trees were already down. Regardless, I don't think we have much control over what WSDOT does in their limited access ROW, unfortunately. Hope this helps explain what is going on - if not let me know.

It appears that a catch basin failed at the end of the ramp allowing storm runoff to flow down the steep slope and damage a USGS gauging station and a WSDOT retaining wall. WSDOT crews responded and later that day they apparently cut down the trees. I am not sure why they did this. I reported this issue to Carol Lumb and Sandra Whiting. I have not heard anything back from WSDOT on this. On a separate note, a large amount of erosion was observed on the east bank of the Green River just below of the SB I- 405 bridge. It appears they have a failing drainage structure on the highway causing water to flow down the steep slope and into the river.

This was due to the recently felled trees obscuring visual access. The masonry landscaping blocks appear to be dislocated from the upper wall at the base of the gauge, and the lower wall at the edge of the trail is tilting from the vertical. I would suggest the slope may need to be reconstructed, after the drainage issues are corrected. I assume the tree cutting is somehow related to the noted slope damages?

I was notified that runoff from a WSDOT ramp is causing damage to a USGS gage and a retaining wall. I was told that approximately 30% of the foundation to the station is no longer supported. I contacted WSDOT earlier today through email about this issue and I am still waiting on a response. I just wanted you to know of this issue. Thanks, Ryan Larson, P.E.

From: Mike Ronda Sent: Friday, January 03, 2014 5:24 PM To: Ryan Larson Cc: Grant Griffin; Robin Tischmak Subject: Drainage Damage to I-405 On/Off Ramps Importance: High Ryan, You may already be aware of this but in my field review this afternoon near the Fort Dent/Interurban intersection I noted a retaining wall collapse and significant undermining of the USGS gauging station on the south edge of the Green River (SW corner of Ft. Dent and IU). If we haven't already alerted the appropriate contacts at DOT, King County Flood District, USACE and/or USGS we probably should do that. It looks like DOT may have a failed drainage system on the SW corner of the intersection and the runoff from the off ramp is running under the jersey barrier and taking a portion of the bridge abutment away as it makes its way down the slope to the river. It doesn't currently look like an imminent failure situation but with a couple more large winter storms without appropriate attention it could turn into a real problem. I've got photos if you would like to see them.
