See Project Description in Responses to CUP Submittal Requirements. A Land Survey is provided in the Project Plans with reference to the Title Report provided and topographic survey of site. The proposed project location involves the reduction of 2 existing parking spaces and unused parking median at the West side of the property parking lot. The proposed location is bounded by landscape islands on the North and West sides of the property. RF Justification - Overview The attached RF Justification Letter was prepared by the assigned Verizon Radio Frequency (RF) Engineer for the area. The associated maps provide the technical design data for RF Engineering parameters regarding the Verizon wireless Network at the City cor Network RF Planning The issue is that although there is existing coverage in the Renton Core there is not adequate capacity to provide a level of service needed to meet current demands. As a result, Verizon has planned several permanent WCF sites in the area - intended to meet and accommodate the demands for adequate wireless services now and into the future. RECEIVED 12/29/2017 amorganroth PLANNING DIVISION Attached is a map of planned and potential site locations in relation to Verizon existing sites within the Renton core, that depict the locations of areas that need service improvements called polygons. The Map is from early 2017, but also includes areas pursued in the past for Network Improvements. The map includes the approaches over recent months in attempts to secure various types of sites including Small Cells and Cell on Wheel (COW) deployment. Unfortunately, the Small Cell polygons have been determined to not be feasible. As discussed with City representatives in the past, the use of a proposed COW is only a stop gap measure needed by Verizon to immediate augment the existing RF signal strength in the Renton core areas needed to provide adequate service while permanent sites are pursued. As a result, the map shows the permanent locations (Polygons) where RF Engineering has identified locations where permanent sites are needed. In this case, the SEA Logan Ave polygon was identified as a candidate search area for a potential permanent site. SEA Logan Ave Candidate Selection & Justification The SEA Logan Ave polygon is located East of the Renton Airport and includes the intersection of Logan Ave and 3rd Street on its borders. The primary candidate was the Renton School District’s Renton Memorial Stadium where the stadium grandstand is of adequate height for a WCF, and the structure currently serves as a WCF support structure for another carrier. Verizon vigorously pursued the site as the primary candidate for the Logan Ave polygon however after several months of due diligence with the City and landowner toward a WCF that meets current codes, the landowner elected to discontinue consideration of the property for a Verizon WCF. The landowner did not provide an explanation as the basis for their decision therefore Verizon was not able to mitigate any articulated concerns. The ability to utilize the other structures of height in and near the polygon were considered and identified as PSE utility or other poles for possible replacement, however those structures had already been considered and eliminated due to issues involving availability of the use of structures in the City R/W. As a result, a raw land (RL) site type was pursued given the other structures in the area did not have significant height or had been eliminated in candidate considerations. Selected Site Considerations The Carpenter Union property was selected utilizing a RL support structure candidate for several reasons: • The property is zoned Urban Center (UC) which is a high impact commercial zone and is the same zone as the primary candidate. • The property is located near the intersection of 2 major arterials in the City of Renton. • There are built structures of height in the area where a WCF support structure will not stand out as the only built structure of height in the immediate area. • There are trees in the area that will provide back drop and/or partial visual screening for a proposed RL structure from adjacent arterials. • The City zoning codes are conducive to the siting of a RL support structure in the underlying zone. Antenna Support Structure Type Considerations Verizon has worked with planning staff in the candidate scoping and structure type selection. Review of zoning and other development codes have concluded that the use of a faux tree at the property is the preferred antenna structure type. A canister type “concealment” support structure was also considered however staff indicated the faux tree was considered conforming as to the pertinent City Codes. As a result, a “monopine” tower to 60’ in height was selected as the proposed antenna support structure with the following considerations: • There are existing trees in the area where a faux evergreen tree “monopine” appears to be compatible since it will not standout due to the cluster effect and the existing of evergreen trees in the general area. • The proposed structure height at 60’ is adequate in height to provide the needed Line of Site required for proper function of a WCF at the Polygon, and within the Verizon Network. • The proposed structure height meets the WAC Exempt from SEPA in the subject zone which reflects the determined compatibility of such as use in the commercial zone for a WCF support structure. • The location is near landscaping meridians that serve as visual and other buffer/berms from adjacent arterials and assist in screening of the Verizon proposed ground based equipment. In summary, Verizon believes the CUP Justification findings as stated above and including the following considerations: 1. All other feasible candidates and existing structures with adequate height have been eliminated in and near the Polygon. 2. The proposal meets the City of Renton WCF and Development Standards and Codes; all applicable local, state and federal laws and ordinances. 3. The proposal meets the SEPA WAC exemption for WCF in a Commercial Zone and there are no known environmental impacts or ECAs at the property, or affected by the proposal. 4. The design meets the criteria for stealth WCF for the zoning regarding proximity to adjacent zoning districts. In closing, Verizon is pursuing a Letter from an Engineer that will satisfy the justification of the requested reduction in setbacks for the tower from adjacent property lines to the North and West. Verizon is also pursuing a Noise Study Report regarding the conformance of the proposal to City Noise Ordinances. Those reports are forthcoming and will be provided as soon as they are received.
