The WCF would be located within the parking lot of the Living Memorial Association ofKennydale on a 1.99-acre site within the Residential-8 (R-8) zoning designation. The site currently has as a 3,552 sq. ft. social hall and gravel parking lot. The WCF would be located north of the social hall and take up 242 sq. ft. in area. The equipment cabinet area would be 150 sq. ft. in size and would be enclosed by a 6-foot high chain link fence with privacy slats. Access to the site would be provided via private driveway off of NE 27th Street. No landscaping improvements or street improvements are proposed. The site has existing glen of trees that screens the interior of the property along the north, east, and west property lines. Evergreen trees are predominant along the east property line and deciduous trees are more predominant north of the parking lot. The trees that would screen the Monopole range from 70 feet in height to over 120 feet. The surrounding area around the WCF site is relatively flat, but the overall lot has steep drop off approximately 60 feet east of the WCF to the May Creek Ravine. The grade change results in a number of critical areas that include an erosion hazard area, a moderate landslide area, and regulated slopes. The site is located, is within the Aquifer Protection Area -Zone 2. The Mean Sea Level (MSL) elevation for the site is 320 feet and the MSL elevation of the proposed Monopole I would be 379.9 feet at its highest point. Ii PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day Appeal Period. B. Mitigation Measures C. 1. The applicant shall submit a geotechnical report to the Planning Division Project Manager prior to building permit review. The applicant shall comply with the recommendations for design, installation, and increased setbacks from regulated slopes. 2. The applicant shall submit a paint color(s) for the Monopole that would appropriately match the surrounding vegetation to the Planning Division Project Manager for approval prior to building permit review. 3. Since the highest elevation of the Monopole (380 feet) punctures the FAR Part 77 (182 feet), the applicant shall submit a Notice of Proposed Construction to the FAA a minimum of 30 days prior to the issuance of any building permit for any wireless communication support structure or attached WCF. The applicant shall also submit a copy of the Notice of Proposed Construction to the City of Renton and comply with any conditions imposed by the FAA.

Environmental Impacts ronmental Review Committee Report LUA09-011, ECF, CU-H Page 3 of 5 The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: 1. Earth Impacts: The area surrounding the applicant's lease area is relatively flat, but is located in a moderate landslide area. Approximately 70 feet east of the proposed Monopole there are regulated slopes and approximately 100 feet east, there is a erosion hazard area. These areas are located in the May Creek ravine. In-between the Monopole and the ravine, there is a gravel parking lot drive aisle and a grass buffer area that separates the parking lot from the ravine. The ravine begins approximately 70 east of the project site and the calculated slope from the beginning of the ravine to the east property line (not the bottom of the ravine) is approximately 75%. The slope of the ravine is densely vegetated. No information as to the type of soil was provided by the applicant; however, the applicant did state that a minimal amount of soil would be disturbed. The proposed Monopole would be installed next to an existing structure within the middle of a gravel parking lot. A geotechnical report will be required prior to building permit review to better assess the construction feasibility of installing a Monopole I on the site. The applicant proposes to conduct a geotechnical report at the time of building permit submittal and as part of the applicant's construction mitigation description, the City of Renton standards stated in RMC 4-4-030 will be followed. Due to the potential for future redevelopment of the subject site, Staff, as a part of the Conditional Use Permit, will propose relocation of the Monopole from the rear of the Memorial Hall to the north end of the parking lot. By relocating the Monopole further to the rear of the property instead of constructing it in the center of the site, the property could be developed without being constrained by the Monopole. Mitigation Measures: Due to the presence ofregulated slopes, the applicant shall submit a geotechnical report to the Planning Division Project Manager prior to building permit review. The applicant shall comply with the recommendations for design, installation, and increased setbacks from regulated slopes. Staff proposes a relocation of the Monopole, which would increase the need for a geotechnical report because it would likely be closer to the regulated slopes. Nexus: SEPA; RMC 4-3-050, Critical Areas Regulations 2. Aesthetics Impacts: The proposed Monopole I would result in visual impacts within an existing single-family neighborhood. The applicant indicates that efforts have been made to assimilate the proposed Monopole I structure into the surrounding single-family residential neighborhood by utilizing a flush-mount design that reduces the visual profile of the structure and to paint the Monopole a color that will allow it to be absorbed into the natural surroundings. The equipment cabinets would be enclosed by a six-foot high fence with privacy slats. To reduce the visual impact from the street, the applicant sited both the Monopole and the equipment cabinet behind a one-story building on a property with existing abundant tree coverage on the western, northern, and eastern sections. The proposed Monopole I's elevation of 60 feet would be well below the tree line, which ranges from 70 feet in height to over 120 feet and consists of both evergreen and deciduous trees. The evergreen trees dominate the eastern portion of the site while the deciduous trees are grouped north of the parking lot. The applicant submitted photographic simulations to illustrate the visual impact of the Monopole I on the surrounding neighborhood at the proposed location. The photographic simulation Photo 1 demonstrates appropriate visual absorption of the Monopole by the existing evergreen trees to the east. Looking north from the photographic simulation Photo 2, the treeline does not do quite as good of a job of absorbing the visual impact as Photo 1. This is a result of a combination of factors: the trees to the north are not as tall as the ones to the east and the trees are further from the street. As time goes on, the trees will increase in height and provide additional screening. Also, the trees to the north are mainly deciduous trees, which would provide better absorption in the spring and summer because of the leaf coverage than in the fall and winter. £RC-REPORT LUA09-0I I d2.doc -- Ci1y of Ren/on Depar!men! of G mity & Economic Developmen! T-MOBILE MONOPOLE 1 ON NE 27m Report of March 2, 2009 ronmental Review Committee Report LUA09-011, ECF, CU-H Page 4 of5 The applicant does not propose any landscaping, citing that by locating it on the backside of a building and constructing a fence with privacy slats, which they contend would adequately screen the equipment cabinets from the public view. During the public comment period, staff received no comment letters from the public in opposition to the project's aesthetic impact on the neighborhood. Mitigation Measures: The applicant shall submit paint color(s) for the Monopole that would appropriately match the surrounding vegetation to the Planning Division Project Manager for approval prior to building permit review. Nexus: SEPA; RMC 4-4-140, Wireless Regulations 3. Transportation Impacts: It is anticipated that the proposal would result in one trip attributable to the project every four to six weeks for technical service. Adequate parking exists for a service vehicle. The proposal could impact operations of the Renton Municipal Airport due to the height and MSL elevation of the proposed Monopole I and its proximity to the Airport. The project site is within Federal Aviation Regulation (FAR) Part 77 Surface applicable to Renton Municipal Airport. The FAR Part 77 at the site location is 182 feet Mean Sea Level (MSL). The MSL height is 320 feet at the base of the Monopole and 380 feet at the top. The FAA may require lighting of the Monopole, which may consist of steady or flashing lights. This impact however could not have much significance because the surrounding tree line exceeds the height of the proposed Monopole I. Mitigation Measures: The applicant shall submit a Notice of Proposed Construction to the FAA a minimum of 30 days prior to the issuance of any building permit for any wireless communication support structure or attached WCF. The applicant shall also submit a copy of the Notice of Proposed Construction to the City of Renton and comply with any conditions imposed by the FAA. Nexus: RMC 4-4-140H Airport Restrictions, FAA regulations E. Comments of Reviewing Departments The proposal has been circulated to City Department and Division Reviewers. Where applicable, their comments have been incorporated into the text of this report and/or "Advisory Notes to Applicant." ./ Copies of all Review Comments are contained in the Official File and may be attached to this report.
