Division #294 Spokane WA 99218 1 | Page DATE: 06/29/2017 Prepared for: Phil Kitzes RE: 900 Renton AV S. Renton WA. Assignment: Provide a tree inventory with: tree tagging, species, condition, tree protection zones (TPZ) and/or critical root zones (CRZ), impact to trees on adjoining properties within 10’ of the site or that have CRZ within the proposed site improvement area, tree post construction viability of trees left onsite. A Sample Plot will be used as a template for forest health and to establish the percentage of viable and non-viable trees on the site. I am to provide a written report of observations facts and findings. Purpose: To fulfill the city code for Tree Retention Associated with Development Activity, for a proposed short plat at: 9?? Renton AV S. Renton WA. Also Referenced as Singh Renton AV S. Short PLAT Methodology: To evaluate the trees for risk and prepare this report I drew upon my 30+ years of experience in the field of arboriculture and my formal education. Following the protocol established by the International Society of Arboriculture (ISA) Best Management Practices (BMP) for Risk Assessment ANSI A300 Part 9 And Construction Part 5. The site assessed for any noted condition that may have a negative impact on the local forest including but not limited to: 1) history of tree failure (wind throw) 2) Change in Wind Patterns 3) soil depth 4) Soil Hydrology 5) grade changes 6) fungal fruiting bodies/decay pathogens. The trees were assessed and: 1. The crown of the tree(s) were examined for current vigor. Inspecting the crown (foliage, buds and branches) for color, density, form, and annual shoot growth, limb dieback and disease. Branches were inspected for cracks and other defects, as well as needs for remedial pruning. 2. The bole or main stem of the tree(s) were inspected for decay, which includes cavities, wounds, fruiting bodies of decay (conks or mushrooms), seams, insects, bleeding, callus development, broken or dead tops, structural defects and unnatural leans. Structural defects include crooks, forks with V-shaped crotches, multiple attachments, and excessive sweep. Site: A140,341 Sq. Ft. (3.22 acre) site proposed for short-plat into 7 7,500 Sq Ft. lots (.17 acre). Lots are proposed to be 150’ X 50’ they may be increased in size to allow for the retention of trees on the western portion of the lots. No other relevant site conditions were noted. approx. 60, 341 SQ. Ft. (1.39 acres) is proposed for short-platting and approx. 80,000 Sq. Ft. (1.84 acres) is proposed to be left unimproved Trees: There was 48 trees in the 10,000 SQ FT. Sample Plot. 28 or 58% were viable and 20 or 42% were not viable. Trees Adjacent to Site: No off-site trees were noted that would be impacted by the proposed short-platting of this site. Tagging: Trees are tagged with aluminum tags and numbered 1-48 A site map (not to scale) is included to help locate the trees.

Singh Short Plat City of Renton Parcel 00720-0196 (LUA17-000803) Dear Phil: On May 10, 2018 I conducted a wetland and stream reconnaissance on the subject property utilizing the methodology outlined in the May 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0). The primary focus of the reconnaissance was to review the findings of the Critical Areas Report prepared by Habitat Technologies dated April 22, 2017. The Habitat Technologies report identified three surface water drainages on the site that originate from culverts along the east side of the property adjacent Renton Ave. S. Per the report, “all three of these surface water drainages were associated with the outlet of concentrated stormwater runoff from City of Renton stormwater systems. As such, these surface water drainages appeared more consistent with intentionally created, artificial features rather than naturally occurring streams. The surface water moved within these drainages appeared in direct response to public stormwater facilities.” Based on my site review I concur with this determination. All three of the identified drainages are clearly depicted as originating from stormwater outfalls on the City of Renton’s GIS mapping (see attached). Since the source of the runoff within the drainages is entirely artificially collected and intentionally discharged onto the site, the drainages should not be considered natural streams. Furthermore, the City of Renton specifically exempts “intentionally created” waters from the critical area regulations per RMC 4-3-050G.7.b.

Singh Short Plat) Hello, I am the owner of the house at 1301 S 9th Street. As you may know, Renton Hill had significant coal mining in the 1900s. When I purchased the house in 2008, the lot next door to me was empty. I assumed it would remain so, as there was a mine entrance on the lot. Nevertheless, someone bought the lot and went forward with building a very large house on the lot. There were numerous problems, both during the construction and after. I would be happy to enumerate the issues with the crews that were doing the work (including some reported illegal dumping and tree cutting on the land of the short plat), but the bigger issue was with the land. During the construction, there was significant land settling, including a cave-in on our neighbours lot (owned at that time by Armondo Pavone). They ended up pumping a great deal of concrete into the site to stabilize the land, and the construction ended up taking the better part of a year. When I purchased the house, I checked the soil, and confirmed that the house was build on clay (likely tailings from the mine). At the time I moved in, there were no cracks in any of the driveways or foundation, and all the floors were level. Some time during or soon after the neighboring house was built, the land shifted resulting in half of the house having a slight slope (enough that a ball will roll on the floor), and a number of cracks in the foundation and driveway. I did not have evidence that there were no cracks in the foundation prior to the house being built, so I couldn't do much. I was made aware that the builders and owners of the house next door to mine had also purchased the block across the street, which is the site of the short plat in LUA17-000803. I am very concerned about this development for the following reasons: 1. It is in the middle of a high severity coal mine area (per http://rentonwa.gov/uploadedFiles/Government/FIT/GIS/PDF_Files/Coal%20Mine%20Hazard.pdf) 2. It has a significant slope, and is a continuation of the steep hill that runs along 9th street 3. It has a stream outlet that is currently drained into the wooded area 4. It is in an area with a high erosion hazard (per http://rentonwa.gov/uploadedFiles/Government/FIT/GIS/PDF_Files/Erosion%20Hazard.pdf) 5. The developers were very careless in their previous construction Some additional details on #3. There is an underground stream (in the storm sewers) that runs along 9th street. It is a year-round stream, and exits on the west side of Renton Ave. There is significant outflow from the stream, and it is currently drained into a marshy area. If this block is developed, what is going to happen with the stream? If it isn't handled, then the soil will become saturated with water, making it more likely to have subsidence issues. I've never interacted with a Notice of Land Use before. What is the next step? Thanks, Erick Thompson DocuSign Envelope ID: 3AFC592E-159A-4444-BD85-1D4D0C6FA626 1 Clark Close From:Erick Thompson <erick.thompson@gmail.com> Sent:Saturday, December 23, 2017 5:43 PM To:Planning Customer Service Cc:Vanessa Dolbee; Clark Close Subject:Re: Concerns about LUA17-000803 (S. Singh Short Plat) Hey Mona, Thanks for the email. I think that should be enough time. I'm at my family's house on Vancouver Island until the 30th. I briefly scanned the critical area report, and one thing jumped out at me. The stream outlet on the northeast side of the lot was marked as seasonal and runoff based. The stream is in the storm drain, and while it does run more heavily in the winter, it is a year-round stream. There are frogs and lizards out there, as my kids and I would go across the street and see them. You can hear the frogs very well all summer. Opening the storm drain to access the stream is actually our earthquake water source in case of emergency. The plan shows that corner as being one of the lots (lot 1). Is the storm drain going to be extended to keep the stream underground? Does the year round nature of the stream change the plan? In addition, there is a seep that crosses under the road on the south side of my lot, but I don't believe it encroaches on the lot in question. For the coal map hazard on the geotechnical report, is there a standard map that was used? I've visited the Renton Historical Museum a while back, and noticed that the coal mine entrance that was in the middle of the lot to the south of ours was not present. In talking to them, it sounds like a lot of the mines were not recorded properly. I don't know if this lack of mapping contributed to the issues during the construction of the house there, but when I spoke to the owners shortly after construction started, they were surprised that there was a coal mine on the lot (to be fair, the entrance was in the middle of a blackberry bramble). There are known mining tunnels under the western half of the lot, and it wouldn't surprise me if there are tunnels or air vents elsewhere in the lot. I need to digest the other portions of the application, but these are the parts that I noticed on a first pass. Thanks, and have a happy holidays as well!

Singh Short Plat) Clark, I am the owner of the house at 1301 S 9th Street. I am writing to formally request an extension of the comment period for Concerns about LUA17-000803 (S. Singh Short Plat), which extends along the block to the immediate west of my house. I got the notice of the plan around Dec 9th, and sent an email to you (Clock Close) on Dec 13th. I got response and some of the planning documents on Dec 21st, and so I have not had time to comment and response. Mona suggested that the comment window could be extended until Jan 5th, which should be enough time to understand and comment on the planning documents. The reasons and questions for the extension are as follows. Background As you may know, Renton Hill had significant coal mining in the 1900s. When I purchased the house in 2008, the lot next door to me (south side, 851 Renton Ave S) was empty. I assumed it would remain so, as there was a mine entrance in the middle of the lot. Nevertheless, someone bought the lot and went forward with building a very large house on the lot. There were numerous problems, both during the construction and after. Some of these problems have permanently damaged my house. The land in question (LUA17-000803) is just across the road, and has similar characteristics, and so I want to ensure that the similar problems do not arise during development of that lot. General areas of concern Coal Mine shafts and soil stability For the coal map hazard on the geotechnical report, is there a standard map that was used? The geotechnical report states that the eastern portion of the lot (where the proposed lots would be) are in a medium area, but Coal Mine Hazard map (http://rentonwa.gov/uploadedFiles/Government/FIT/GIS/PDF_Files/Coal%20Mine%20Hazard.pdf) seems to show that part of the lot being in a high risk area. I’ve been made aware that these maps are approximate (for example, they did not contain the entrance on the 851 Renton Ave S lot), so I would like additional time to look at historical coal mine maps. However, I know these are also not complete, so how was the determination of risk performed? If the maps are not accurate enough to have prevented issues during the construction at 851 Renton Avenue South, how will issues where the slope is far greater and risk of erosion/landslide greater (see http://rentonwa.gov/uploadedFiles/Government/FIT/GIS/PDF_Files/Erosion%20Hazard.pdf and http://rent onwa.gov/uploadedFiles/Government/FIT/GIS/PDF_Files/SteepSlopes.pdf) be prevented?

I received notice of a plan to develop the lot across Renton Ave S from my house. I requested and was granted an extension of the public comment period due to numerous concerns I have about the development of that lot. I appreciate your assistance in providing information about the project. My concerns are centered around soil stability due to coal mine hazards, and due to presence of a wetland and stream in the area to be developed. The existing documentation does not address these concerns. Property location The property that is considered for development (LUA17-000803- S. Singh Short Plat), is located on the west side of Renton Ave S, between S 9th and S 10th streets, in the Renton Hill neighborhood. The site plan, as provided by the owner, is shown in Figure 1 below.

Singh Short Plat, LUA17-000803, ECF, SHPL-A Dear Mr. Kitzes: The Planning Division of the City of Renton accepted the above master application for review on December 6, 2017. During our review, staff has determined that additional information is necessary in order to proceed further. The following information will need to be submitted before April 11, 2018 so that we may continue the review of the above subject application:  Under a previous land use application made for this site (LUA05-089, SHPL-H, ECF), the City of Renton received professional studies identifying several onsite streams and one onsite wetland. A copy of some of the exhibits and figures from these previous report are included as an attachment for your reference (Attachment A). A copy of the land use file is available in Laserfiche through the Office of the City Clerk. Please revise and resubmit a Critical Areas Report that identifies and evaluates all existing critical areas onsite. Submitted reports shall comply with all current Critical Area Regulations of the Renton Municipal Code (RMC). Please note that the City may require an independent review of an applicant’s report when appropriate due to lack of substantial documentation of impact avoidance as part of the first study. Evaluation by an independent qualified professional is paid for at the applicant’s expense and is selected by the City (RMC 4-3-050F.6.a).  A preliminary drainage plan and Technical Information Report (TIR) prepared by Core Design dated August 21, 2017 were submitted to the City as part of the site plan submittal.

Singh Short Plat, LUA17-000803, ECF, SHPL-A Dear Mr. Kitzes: The Planning Division of the City of Renton accepted the above master application for review on December 6, 2018. The application was put on hold on January 11, 2018. A response to the requested information was provided to Staff for review via email. The submitted material included a response letter, revised Technical Information Report (TIR), a Wetland and Stream Reconnaissance Report prepared by Altmann Oliver Associates, LLC (dated May 16, 2018), and a copy of the preliminary short plat plan. In the on-hold letter, Staff identified a previous land use application (LUA05-089, SHPL-H, ECF) made for this site that included professional studies identifying several onsite streams and one onsite wetland. After reviewing the submitted reports and comparing them to the old studies, Staff found inconsistencies between the documents. Due to the critical areas and project area conditions, and in order to resolve the inconsistency issues and obtain accurate information on the streams and wetlands, an independent secondary reviewer will be retained by the City at the applicant’s expense. A third-party professional will be tasked with reviewing the Critical Areas Report prepared by Habitat Technologies (dated April 22, 2017) and the Wetland and Stream Reconnaissance Report prepared by Altmann Oliver Associates, LLC (dated May 16, 2018). Prior to retaining the consultant, I will send information on the scope of work, estimated cost, and estimated timeline for the secondary review to you. Additionally, the TIR must follow the City of Renton Surface Water Design Manual (SWDM), not King County’s. By adding additional flow to the existing conveyance system to the east, you must follow the requirements found in SWDM 1.2.4.2 for existing systems and you must demonstrate that the 100-year peak flow to the existing system will not create or aggregate a severe flooding problem or severe erosion problem, as described in SWDM Core Requirements #2, Section 1.2.2.

Singh Short Plat Critical Areas Review 32847.F Introduction The City of Renton (City) has requested Otak, Inc. (Otak) to conduct a review of associated critical areas reports for the proposed 6-lot hillside subdivision called the S. Singh Short Plat. Two critical areas reports have been submitted with the land use application: a Critical Areas Report prepared by Habitat Technologies (dated April 22, 2017) and a Wetland and Stream Reconnaissance Report prepared by Altmann Oliver Associates, LLC (dated May 16, 2018). A previous land use application called the Defoor Short Plat included a record of professional studies identifying critical areas on the subject property. The City has requested Otak to conduct a review to resolve inconsistencies between the two new reports and previous records on file regarding the critical areas on site. The subject property, Parcel #0007200196, is located on Renton Avenue S between S 9th Street and S 10th Street in the City of Renton, King County, Washington. Otak conducted a field survey of the subject property and a review of previously prepared critical areas information to evaluate the classifications of streams, drainage features, and wetlands on site. Otak also evaluated the S. Singh Short Plat plan and its compliance with the City of Renton Municipal Code (RMC) Chapter 4-3-050 (Critical Areas Regulations).

Washington. This report was requested by Jason Walker of Talasaea Consultants on April 26, 2006. The purpose of the requested services is to qualitatively assess the geomorphic character and origin for two streams, Stream B and Stream A, on the Property. The project work scope consists of reviewing reports and maps provided by Talasaea C()nsultants, and visiting the Defoor Property to observe the stream.... The Reports reviewed by GeoEngineers include: Hydrogeological Consultation; Stream B Corridor, dated March 24, 2006 and prepared by Icicle Creck Engineers (ICE); Coal Mine Hazard Assessment and l)rcliminary Geotechnical Evaluation, Renton Hill Property, dated June 10, 2005, prepared by ICE; and a section of a report entitled Defoor Property --- Wetland Study, Stream Assessment, Habitat Study, Watershed Restoration and Mitigation Plan, dated October 3, 2005, prepared by Talasaea Consultants. GcoEngineers also reviewed the Wetland and Stream Basin Restoration Plan, Existing Conditions and Overview Plan, dated 28 June .. 2005, prepared by Talasaea Consultants_ OBSERVED CHANNEL CONDITIONS The site visit was conducted on April 28, 2005. The reconnaissance included walking the length of Streams A and B from Renton A ve So to the base of the slope just east of wetland B. Stream A originates up-!,'Tuciient of Renton Ave S, passes through a culvert beneath the road and flows downstream in a well defined swale with side slopes inclined from 20 to 50 percent. The swale is reflected as a dip in Renton Ave So. The Stream A cross section dispJay au-shaped Hoor with side walls inclined to the angle of repose of the soils. Stream B conditions are well described in the ICE March 24 2006 report. The "stream" originates at a culvert outfall at Renton Ave S. No observable expression of a drainage appears to extend upslope from Renton Ave So. Thc culvert is situated on a topoh'Taphic high point on the right limb of the Stream A swale. Immediately do\vn gradient of the culvert outfall, the stream consists of two or three deeply incised channels with nearly vertical side walls. The channels do not reside in a topographic swale.

ICE previously completed a preliminary geotechnical evaluation and coal mine hazard assessment of the Renton Hill Property; the results were presented in ICE's report dated June 10, 2005. ICE also completed an evaluation of Protected and Sensitive Slope areas; the results were presented in ICE's report dated September 30,2005. We understand that a question has been raised by Jason Walker of Talasaea Consultants, LLC (the wetland and stream consultant for the project) as to whether or not Stream B is a naturally-formed stream. ICE has been requested by Terry DeFoor the project owner, to assist in this evaluation of Stream B from a geomorphological (landform genesis) and hydrogeological perspective. The morphology of this stream is important in identifying its proper sensitive area classification and buffer requirements. To accomplish this evaluation, ICE reviewed historic mine maps dating back to 1911 and historic aerial photographs dated 1936, and completed a detailed surface reconnaissance of the Stream B corridor. STREAM B OVERVIEW We understand that Stream B was identified by Talasaea. Stream B is located in the south portion of the Renton Hill Property, and flows from east to west through an undeveloped forested area. A second stream, referred to as "Stream A" exists to the south of Stream B. Stream B is bordered by Renton A venue South and residential development to the east, residential development to the north, and undeveloped forested land to the south and west. The Stream B corridor and surrounding area have a relatively long history of site use, including residential development (Renton Hill is one of the oldest residential neighborhoods in the City of Renton) and underground coal mining. The site is located at the historical location of the Renton Mine that was active from about 1874 through 1933. HISTORICAL MINE MAP REVIEW We reviewed historic mine maps of the Renton Mine dated 1911, 1918, 1919 and 1932. These historic maps show the underground mine workings and, to a limited extent, surface features such as 230 NE Juniper Street, Suite 101 • Issaquah, WA 98027-2519 • www.iclclecreekengineers.com • (425) 427-8187 phone • (425) 427-6629 fax EX t.f-- Entire Document Available in Laserfiche Submittals Folder DocuSign Envelope ID: 3AFC592E-159A-4444-BD85-1D4D0C6FA626 .• ~ ... + ... ... ---. .

This letter is in response to your letter dated November 17, 2005 requesting reconsideration of the classification of 3 un.;.mapped streams (Stream B, Stream C, and Drainage 1) as identified in the Wetland Study, Stream Assessment, Habitat Study, Watershed Rest-oration, and Mitigation Plan llr'Cpared by Talasea Consultarits, Inc. dated. June 28, 2005 (revised October 3, 20(5)~ In yOUT letter you indicate that the creation of the 3 un-mapped streams was·the result of erosion due to point-discharge of st()rmwater and sQould be considered artificial and reJUlatedaSClass 5 streams. RMC 4,.3- 050L.l.a.v defines a Class 5 stream as non~regulated waters that "flow within an artificially constructed channel where no naturally defined channel had previously existed." The point discharge of stormwater onto the subject site does not constitute an . artificially constructed channel that would be clasSified as a Class 5 stream. In your letter you also cite a previous project within the City, Sunnybrook Preliminary Plat (LUA05-127, SA-H, PP, ECF), where the modification of7 drainage channels was pennitted. You indicat~ that the previous approval should serve as a precedent for the streams located on the subject property. Since "the review and approval of the Sunnybrook Preliminary Plat, subsequent critical area regulations have been adopted, which include a new stream definition and stream claSsification system. Therefore, as the current project was submitted under the subsequent regulations, the previous approval of the alteration of 7 drainages would not be a precedent. The previous determination of the classification of the streams dated November 3, 2005 stands. . -------------IO-S-S-S-ou-fu--G-ra-dy--W.-ay-.-R-e-n-ro-n-,W.--as-h-in-gt-o-n-9-80-S~S------------~ (!)

Due to the availability of additional information, both enclosed and forthcoming, we request a reconsideration of your determination, and request your examination of the information and historical factors that have effectively created several drainage features on the subject properties. We also request a reconsideration of the decision to allow a Class 5 rating for Stream S, Stream C and Drainage 1 based upon historical evidences suggesting the feature's artificial origin and past precedent set by the City in the previous review and classification of similar features. To preserve our options for a formal appeal, we also request that this notification be filed at this time for this purpose. We understand that there has been some difference of opinion, and subsequent internal discussion and meetings regarding the definition of a Class 5 classification for Stream C and Drainage 1. From communication between Hugh Mortensen (The Watershed Company) and Per Johnson (Talasaea Ecologist) on 25 October 2005, and from your 3 November letter, we understand that the City has declined the guidance of their peer review consultant and is attempting to regulate artificial drainages that have been intentionally created due to the discharge of untreated and undetained stormwater. Furthermore, Jill Ding, of the City of Renton, told us (in a telephone conversation on 25 October 2005) that the City desires to conduct a hearing regarding the Defoor project to clarify the new code for the purpose of defining City policy. If future meetings are scheduled between the City's peer review consultant and staff to discuss the Defoor properties, we would appreciate the opportunity to attend and provide any necessary information or clarification, as this would expedite the coordination and correspondence involved for this project, and associated time and costs for all parties.

Administrator Subject: Administrative Determination of Un-;mapped StreamlWetland Classification for Defoor Properties (parcel Nos. 0007200196, 0007200194, and 2023059085) Dear Mr. Chen: This letter is in response to your request for the classification of 4 un-mapped streams and two unmapped wetlands as identified, in the Wetland Study, Stream Assessment, Habitat Study, Watershed Restoration, and Mitigation Plan prepared by Talasea -Consultants, Inc. dated June 28, 2005 (revised October 3, 2005). BACKGROUND A Wetland Study, Stream Assessment, Habitat Study, Watershed Restoration, and Mitigation Plan prepared by Talasea Consultants, Inc. dated June 28, 2005 was submitted to the City of Renton with the preliminary short plat and preliminary plat applications for the Defoor Preliminary Short Plat and theDefoorPreliminary Plat. The report identified 3 streams, 2 drainages, and 1 wetland on the subjeCt properties. The report recommended that Streams B and C and Drainages land 2 be classified as Class 5 streams', which are exempt from the City' scritical areas regulations per RMC 4-3-050B.l. Stream A was recommended to beClassified asa Class 4 stream,which requires a 35-foot-buffer and Wetland A was recommended to be a Class 3 :wetland with 25-foot required buffers. The Watershed Company (City's environmental consultant) conducted a site visit August 25th, 2005 and reviewed the applicant's report. A comment letter from The Watershed Company dated September 15, 2005 concurred with the applicant's recommended -classification for Wetland A, Stream A, and Stream C, however did not concur with the applicant's recommended classification for Sti"eamB and Drainage 2 and identified a wetland that had not been delineated. The W~tershed Company recommended that StreamB be classified as a Class 3 stream, that Drainage 2 be identified as an extension of Stream A, a Class 4 stream, and ih,at the unmapped wetland be classified as a Class 3 wetland. Arevised Wetland Study, Stream Assessment, Habitat Study, Watershed Restoration, and Mitigation Plan prepared by TruaseaConsuitants, Inc.

Singh Short Plat, LUA17-000803, ECF, SHPL-A, dated January 11, 2018 Dear Mr. Singh: As requested, The Riley Group, Inc. (RGI) is providing this letter to address coal mine hazard issues, requested in the referenced notice from the City of Renton. We previously prepared a Geotechnical Engineering Report (GER) for the project, dated March 14, 2017. Coal Mine Hazard Areas The subject site is located on Renton Hill, an area extensively mined for coal in the late 1800’s and early 1900’s. Portions of the site are mapped as Medium and High Coal Mine Hazard Areas on the City of Renton online GIS. In assessing potential coal mine hazards at the site, we reviewed The Washington State Coal Mine Map Collection: A Catalog, Index, and User’s Guide by Henry W. Schasse, etc. (1994), and The Coal Fields of King County by George Watkins Evans (1912), and online mine maps from the Renton Mine on the Washington DNR Geologic Information Portal. Subsurface Geology of the Renton Mine The site is underlain by sandstone, mudstone, shale, and coal of the Renton Formation, deposited in the Upper Eocene. Portions of three coal beds were mined at the Renton Mine; Bed No. 1, No. 2, and No.3. The coal beds ranged in thickness from about 11.5 to 17 feet and were separated by large sandstone and shale units ranging in thicknesses from 85 feet between the lowest No.3 and the middle No. 2, and 110 feet between the No. 2 and the upper No. 1 coal bed. The main slope of the Renton Mine was originally sunk at an angle of about 10 to 11 degrees down the No. 3 coal bed from where it outcropped on the surface (approximately 130 feet west of the subject site). The attached Cross Section (Figure 2) was prepared along the alignment of the main slope using surface topography and approximate dip and location of the No. 3 slope. The relative locations of the No. 2 and No. 1 coal beds are also shown.

Particular emphasis was placed on an appropriate categorization of the small offsite wetland and three identified surface water drainages consistent with the provisions of the Washington State Wetland Rating System for Western Washington: 2014 Update Publication #14-06-029 (Hruby 2014), and the City of Renton Chapter 4.3.050 – Critical Areas Regulations. The small offsite wetland and surface water drainages had previously been defined within a wetland assessment completed by Talasaea Consultants, Inc. during 2006. Offsite Wetland: As identified within the recent assessments, this small offsite wetland exhibited all three of the established criteria for designation as a “wetland.” The wetland exhibited slope characteristics with hydrologic support provided by hillside drainage (noted below as Drainage B) and seeps at the edge of the wetland. The soil throughout this wetland appeared dominated by captured alluvial sediments that were well intermixed with grass and sedge roots. As identified onsite the downslope edge of t his wetland area was formed by an old concrete foundation/wall installed either for prior buildings or specifically to create a small ornamental pond. Plant species dominant within is wetland included reed canarygrass (Phalaris arundinacea), small fruited bulrush (Scirpus microcarpus), and common lady fern (Athyrium filix-femina). The outer boundary of this wetland included red alder (Alnus rubra), salmonberry (Rubus spectabilis), Himalayan blackberry (Rubus procera), rose (Rosa spp.), and Douglas spiraea (Spiraea douglasii) (see Photos). As defined using the Wetland Rating System (Hruby 2014) this offsite wetland was identified to achieve a total functions score of 16 points (with 4 habitat points) (Appendix A). As defined by the City of Renton a wetland with a total functions score of 16 points would meet the criteria for designation as a Category III Wetland.

Singh Short Plat, LUA17-000803, ECF, SHPL-A Dear Mr. Kitzes: The Planning Division of the City of Renton (“City”) determined the subject application complete on December 6, 2017. The City acted as the designated lead agency and completed the environmental review process and issued an administrative decision for the 6-lot hillside subdivision at 1003 Renton Ave S Lot (APN 0007200196) on May 3, 2019. After issuance of the SEPA determination and administrative decision, it has come to the City’s attention that the subject application did not follow proper agency notice requirements per WAC 197-11-510(1) and 197-11-508. Due to the procedural error the SEPA determination is hereby withdrawn per WAC 197-11-340(3) and consequently the Administrative Decision for the short plat (SHPL-A) is also withdrawn. To ensure proper agency notice is provided the subject application will be re-noticed and a new threshold determination will be issued, followed by a new administrative decision. Please contact me at (425) 430-7289 if you have any questions. Sincerely, Clark H.

The 3.22 acre property is primarily forested and is located on the westerly edge of Renton Ave S, between S 9th St and S 10th St within the Residential-8 dwelling units per acre (R-8) zone. The proposed lots of the short plat would range in size from 7,824 square feet (sf) in area to 9,996 sf. The remainder of the site would be divided between a 9,975 sf stormwater tract and ±79,712 sf critical areas tract. The residential density is roughly 4.3 dwelling units per net acre. Access to the residential lots would be from Renton Ave S. Half-street frontage improvements would be completed along Renton Ave S. Slope gradients are generally 25 to 35 percent, with steeper slopes bordering a series of east-west drainages that descend the slope to the west. The site contains regulated geological hazardous areas such as steep slopes, erosion, landslide, seismic, and coal mine hazards. A majority of the trees within the heavily treed site would be retained. Tree removal would be primarily associated with the lots and stormwater tract improvements. The applicant submitted a Geotechnical Report, Geotechnical Addendum, Technical Information Report, Arborist Report, Critical Areas Report, Wetland and Stream Reconnaissance Review, and Offsite Wetland and Drainages Report.
