February 8, 2016 Kevin O’Brien Taylor Development, Inc. 15 Lake Bellevue Drive, Suite 102 Bellevue, WA. 98005 RE: Critical Area Report- Weston North City of Renton, Washington SWC Job #16-107 Dear Kevin, This report describes our observations of jurisdictional wetlands, streams and buffers on the proposed Weston North Preliminary Plat, located on Parcel #1123059002, in the City of Renton, Washington. The 2.3 acre site is located in the SW ¼ of Section 11, Township 23 North, Range 5 East of the W.M. in King County Washington. METHODOLOGY Ed Sewall of Sewall Wetland Consulting, Inc. inspected the site on June 17, 2015 as well as February 23, 2016. The site was reviewed using methodology described in the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987), and the Western Mountains, Valleys and Coast region Supplement (Version 2.0) dated June 24, 2010, as required by the US Army Corps of Engineers as well as the City of Renton. Soil colors were identified using the 1990 Edited and Revised Edition of the Munsell Soil Color Charts (Kollmorgen Instruments Corp. 1990). Sewall Wetland Consulting, Inc. PO Box 880 Phone: 253-859-0515 Fall City, WA 98024 Weston North/#16-107 Sewall Wetland Consulting, Inc. February 8, 2016 Page 2 Above: King County Parcel Map of the site. OBSERVATIONS Existing Site Documentation. Prior to visiting the site, a review of several natural resource inventory maps was conducted. Resources reviewed included the National Wetland Inventory Map and the NRCS Soil Survey online mapping. Soil Survey According to the NRCS Soil Mapper website, the site is mapped as Alderwood gravelly sandy loam 0%-8% slopes (Map unit AgC. Alderwood soils are not considered to be wetland or hydric soils according to the publication Hydric Soils of the United States (USDA NTCHS Pub No.1491, 1991). Weston North/#16-107 Sewall Wetland Consulting, Inc. February 8, 2016 Page 3 Above: NRCS Soil map of the study area. National Wetlands Inventory (NWI) According to the NWI map for the site, a forested wetland is located immediately south of the site. Above: NWI Map of the study area Weston North/#16-107 Sewall Wetland Consulting, Inc. February 8, 2016 Page 4 Pleasant Path/Weston Plat Sewall Wetland Consulting worked on the Pleasant Path/Weston Plat to the south of the site. That property contained a forested wetland that was classified as a Category 2 wetland under the old 3-tier Renton Wetland Rating system. As a Category 2 wetland, it had a 50’ buffer measured from the wetland edge. Field observations Uplands The site contains a single family home, as well as two outbuildings and associated gravel driving and parking area located on the west side of the site. Several large Douglas firs are located near the home as well as several apple trees along the south boundary. The remainder of the site is a large mowed lawn/field with a small bamboo stand just east of the home. The pasture portion of the site is vegetated with a mix of bluegrass and orchard grass with dandelion and cats ear also present. A single bitter cherry as well as a small clump of red alder is located along the south boundary to the east. Soil pits excavated in the upland portion of site were found to have dry, gravelly loam soils with soil colors of 7.5YR 2.5/3. Soils were found to be dry within the upper 16” during all of our site observations. The site is bordered by the Olympus Villa Palt to the north, another large plat to the east, and single family hoes to the south, and Nile Avenue NE to the west. Wetlands The northern edge of a forested wetland located south of the site extends onto the south boundary. Below is a description of this wetland; Weston North/#16-107 Sewall Wetland Consulting, Inc. February 8, 2016 Page 5 Wetland A The north edge of a forested wetland was flagged along the south edge of the site with orange wire flags labeled A1-A7. The edge of the wetland is topographically well defined and is well defined by vegetation. The wetland is vegetated with an immature forested overstory of red alder, with an understory of sitka willow, salmonberry, Himalayan blackberry, hardhack, lady fern, creeping buttercup, soft rush and reed canary grass. Soil pits excavated within the wetland revealed a gravelly loam soil with a color of 10YR 2/2 in the A-horizon, with a B-horizon with a soil color of 10YR 3/2 with common, medium, distinct redoximorphic concentrations. Soils were saturated near the surface during our winter observation of the wetland. Using the US Fish and Wildlife Wetland Classification Method (Cowardin et al. 1979), this wetland would be classified as PFO1C. Using the WADOE 2014 Wetland Rating system and rating the wetland as a depressional wetland, this wetland scored a total of 16 points with 3 for habitat. This indicates a Category III wetland. Under City of Renton Municipal Code “Category III wetlands have a 75’ buffer measured from the wetland edge. Proposed Project The proposed project is the construction of a 6 lot residential Plat with associated infrastructure. The project proposes to reduce the low functioning lawn, 75’ standard buffer of the Category III wetland by 25% as allowed by Code to 56.25’. This allowance for buffer reductions by 25% is RMC 44.3.050.G.2. In order to meet the 25% reduction, the criteria in RMC 4.3.050.H.2. must be met. These criteria are as follows RMC 4.3.050.H.2. Authority and Documentation of Required Findings: Based upon an applicant’s request, and the acceptance of a wetland and/or stream or lake study, mitigation and enhancement plan, the Weston North/#16-107 Sewall Wetland Consulting, Inc. February 8, 2016 Page 6 Administrator may approve an alteration to the minimum buffer widths where the applicant can demonstrate that through enhancing the buffer and the use of low impact development strategies the reduced buffer will function at a higher level than the standard buffer. Determinations and evidence shall be included in the application file. The City shall also evaluate all proposals using the following criteria, in the order below. The development plan will: Response: The proposed project will have a 56.25” buffer (75% of the standard 75’ buffer) which will be enhanced through the installation of native woody vegetation. Currently this buffer is entirely mowed lawn. This mowed grass buffer, even in its 75’ full standard width, provides little buffer function. The installation of woody trees and shrubs will create a natural barrier to intrusion into the wetland, increase forage and species diversity for wildlife, increase a source of organic material that can contribute to the wetland, increase surface water flow path vegetation as well as create shade for the wetland. a. Avoid any disturbances to the critical area or buffer; No disturbances to the wetland are proposed. Avoiding portions of the buffer would reduce the number of lots on the property by 40% and make the project financially not feasible. The reduced buffer will be enhanced to increase buffer function over current low function lawn buffer. Reducing the buffer is necessary to be able to fit two of the lots on the plat due to the close proximity of NE 7th Place to the North. b. Minimize any critical area or buffer impacts; The buffer has been reduced by 25% as allowed by Code which is the minimum that would make the lots feasible. In order to reduce buffer intrusion the house configuration on the lot has been turned 90 degrees rom the normal orientation to make them fit. c. Compensate for any critical area or buffer impacts; As allowed by Code, the compensation for reducing the buffer by 25% is enhancement of the entire buffer area (12,206sf) with native tree and shrub species. Weston North/#16-107 Sewall Wetland Consulting, Inc. February 8, 2016 Page 7 d. Restore any critical area or buffer temporarily impacted or lost; NA e. Create new critical areas and buffers for those lost; and NA f. Enhance an existing degraded buffer to compensate for lost functions and values in addition to restoring or creating a critical area. As previously described 12,206sf of degraded, lawn wetland buffer will be enhanced with native tree and shrub species to increase overall buffer function. This mitigation area will be monitored over a 5 Year period. Proposed Mitigation The proposed Wetland Buffer Enhancement is detailed in the attached plan titled Critical Area Mitigation Plan – Plate of Weston North, dated 2-5- 16. The text below has been taken from the above described plan; PLAN GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS: PLAN GOALS, OBJECTIVES, AND PERFORMANCE STANDARDS ARE OUTLINED INTHE TABLE BELOW.

In this case, identify which hydrologic criteria in questions 1-7apply, and goto Question 8. • 1. Are the water levels in the entire unit usually controlled by tides except during floods? ^ffS^^to^-^ YES - the wetland class is Tidal Fringe - go to 1.1 1.1 Is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can he classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is an Estuarine wetland and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO-goJfj-3-^ YES-The wetland class is Flats Jfydurwetland can be classified as a Flatswetland, use the form for Depressional wetlands. D oes the entire wetland unit meet all of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year] at least 20 ac (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m). NO - go to 'T~^ YES - The wetland class is Lake Fringe (Lacustrine Fringe) ire wetland unit meet all of the following criteria? .The wetland is on a slope (slope can be very gradual), , .The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, ater leaves the wetland without being impounded. NO - go to sj1 YES - The wetland class is Slope NOTEfSuface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unitmeetall of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, The overbank flooding occurs at least once every 2 years. Wetland Rating System for Western WA: 2014 Update Rating Form - Effective January 1,201S 3 Wetland nam«^WJumber_ $QjjgLiDj£^ YES - The wetland class is Riverine NOTE: The Riverine unit can contain depressions that are filled with water when the river is not flooding Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year? This means that any outlet, if present, is higher than the interior of the wetland. NO - go to 7 YES - The wetland class is Depressional Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding? The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO-goto8 YES - The wetland class is Depressional Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. r.'HS.V. classes within the wetland unit being rated ;'&>\^:':-Vv;V;';*.
