SR-402-010 (27) PCD:SF:JT:AS:JL:TK:F:\PLAN\SHARE\COUNCIL\STRPT\2004\04APP-004continued.doc Council Mtg: March 22, 2005 Santa Monica, California TO: Mayor and Councilmembers FROM: City Staff SUBJECT: Appeal 04APP004 of the Planning Commission’s California Environmental Quality Act (CEQA) Determination Exempting the Construction of an Unmanned Wireless Telecommunication Facility from Environmental Review. Applicant: Infranext, for AT&T Wireless; Appellant: Matthew Baird. INTRODUCTION This report recommends that the City Council deny the appeal and uphold the Planning Commission’s determination of a Class 3, Section 15303, Categorical Exemption as provided by the California Environmental Quality Act (CEQA), for the construction of an unmanned wireless communications facility on the roof of an existing commercial building. BACKGROUND On September 28, 2004, the City Council continued the subject application after receiving testimony and documenting evidence from the applicant, appellant and members of the public who preferred to place testimony on the record that evening rather than returning at a later date. The item was continued in order for the applicant to address an apparent calculation discrepancy on a form that is used by the Federal Communication Commission (FCC) to determine compliance with applicable standards related to wireless communication facilities and radio frequency emissions. The applicant had submitted this form to the City prior to the September hearing. On 1 November 3, 2004, the applicant submitted a Radio Frequency Power Density Emissions Study, included with this report as Attachment A, to demonstrate compliance with FCC regulations. This study was forwarded to an independent consultant to evaluate the accuracy of the document and to provide a recommendation as to whether the facility would comply with applicable FCC regulations (Attachment B). DISCUSSION The attached reports explain the applicant’s compliance with FCC regulations in technical detail. The independent evaluation concludes that the report detailing the planned operation of the proposed wireless communication facility was prepared properly and the facility would comply with applicable FCC regulations. Section 704 of the Telecommunications Act of 1996 (TCA) prohibits local government from denying an application to construct a cell site based upon the environmental effects of radio frequency (“RF”) emissions from the proposed wireless site: No State or local government or instrumentality thereof may regulate the placement, construction, and modification of personal wireless service facilities on the basis of the environmental effect of radio frequency emissions to the extent that such facilities comply with the [Federal Communication] Commission’s regulations concerning such emissions. Since the applicant has demonstrated compliance with FCC regulations, as verified by the City’s consultant, the City cannot require additional environmental review to address the claimed environmental effects of radio frequency emissions. Consequently, the City’s determination that the project is categorically exempt pursuant to Class 3 of the 2 CEQA Guidelines was appropriate. Moreover, claims by the appellant that certain exceptions to the Class 3 exemption apply are unavailing since these claims are also premised on the perceived effects of radio frequency emissions. The federal government has simply preempted this area of state and local regulation. A concern identified in a letter (Attachment C) subsequent to the hearing and communicated to the applicant was that the before and after photo simulations of the wireless facility were in fact the same photograph. The applicant asserts that the post construction appearance will look the same as the existing conditions. If the project moves forward and is constructed, staff will use the applicant’s photo simulation to evaluate the installation to ensure that the facility looks the same as the existing built condition. Additional background information and project analysis is contained in the prior staff report, which is included as Attachment D. Because the City does not have the authority to deny the application based solely on environmental effects, and given the minimal visual impacts associated with the facility, as well as the improved wireless coverage provided to residents, businesses, and visitors, the Zoning Administrator and Planning Commission approved the requested Use Permit application. In doing so, both decision- making bodies relied on the Class 3, Section 15303 Categorical Exemption provided in the California Environmental Quality, which was appropriate and consistent with state law as detailed in this and the attached report. 3 CEQA STATUS The project is categorically exempt from the provisions of California Environmental Quality Act (CEQA) pursuant to Section 15303, Class 3 of the State Implementation Guidelines in that the project involves the installation of limited new commercial wireless communication antennas and associated mechanical equipment on the roof of an existing commercial building. The wireless facility is in compliance with FCC requirements regarding wireless facilities. In addition, as detailed herein, the proposed facility has been designed to limit any visual impacts by being located behind the existing parapet walls. PUBLIC NOTIFICATION Pursuant to Municipal Code Section 9.04.20.22.050, notice of the public hearing was mailed to all owners and residential and commercial tenants of property located within a 300 foot radius of the project and published in the “California” Section of The Los Angeles Times at least ten consecutive calendar days prior to the hearing. A copy of the notice is contained in Attachment E. BUDGET/FINANCIAL IMPACT The recommendation presented in this report does not have any budget or fiscal impact. RECOMMENDATION 4 It is recommended that the Council deny the appeal (04APP004) and uphold the Planning Commission’s CEQA determination exempting the proposed project from further environmental review, based upon the following finding: FINDING(S) 1. The project is categorically exempt from the provisions of California Environmental Quality Act (CEQA) pursuant to Section 15303, Class 3 of the State Implementation Guidelines in that the project involves the installation of limited new commercial wireless communication antennas and associated mechanical equipment on the roof of an existing commercial building. In addition, the proposed facility has been designed to limit any visual impacts by being located behind the existing parapet walls. Portions of the existing parapet will be removed and replaced with a fiberglass screen, textured, painted, and sized to match the existing building condition. As a result, the only visible antenna from the public right-of-way, will be the flush mounted panel antenna on the penthouse, also painted to match the building, which will not be easily seen by motorists or pedestrians. The mechanical equipment associated with the antennas will be located within the building and will not be visible. The wireless facility will be installed in compliance with FCC regulations concerning radio frequency emissions.

Secondly, I heard considerable talk about the city NOT having authority in this matter because the authority was vested with the FCC.After spending my life working in the construction business, I wondered why and how a "facility" could be built, I believe on top of a building, without it falling into the authority of Building and Safety? If only this"wireless communication facility" were plugged into a standard 110 volt plug maybe then this would make this project exempt. Never the less I heard no discussion of this aspect of item 6-A.In conclusion if this "facility weighted only 6 Oz's and was in fact plugged into a standard 110 volt plug; I still believe that because of the nature of this advanced unstudied technology ; Building and safety should have some authority in this project. I would appreciate your reply to these questions and concerns.

Applicant: Infranext, for AT&T Wireless; Appellant: Matthew Baird. INTRODUCTION This report recommends that the City Council deny the appeal and uphold the Planning Commission’s determination of a Class 3, Section 15303, Categorical Exemption as provided by the California Environmental Quality Act (CEQA), for the construction of an unmanned wireless communications facility on the roof of an existing commercial building. BACKGROUND The applicant proposes to construct an unmanned wireless telecommunication facility on the roof of an existing five-story commercial building. The equipment will consist of a GPS antenna, a flat panel antenna, and three sectors of two antennas each on the roof, with the associated mechanical equipment located within the building on the fifth floor. The Zoning Administrator approved the subject Use Permit application on October 16, 2003. The approval was based on findings demonstrating the project’s consistency with the General Plan and compatibility with other uses in the general vicinity. In addition to standard conditions of approval, three special conditions were added requiring the 11 applicant to demonstrate compliance with applicable Federal Communication Commission regulations (FCC), removal of abandoned equipment, and modifications to an existing fire exit. The last condition was in direct response to public testimony and to ensure the security of the wireless facility. An appeal of the Zoning Administrator’s determination was filed on October 30, 2003. The appellant believed that the project would result in a diminution of property values and create a negative visual impact on the surrounding neighborhood. At its February 18, 2004, meeting, the Planning Commission denied the appeal and upheld the Zoning Administrator’s approval of the Use Permit with an additional condition that any replaced portions of the parapet be designed to match the existing parapet and that the antenna structures not exceed the height of the existing parapet. On March 1, 2004, an appeal was filed challenging the Planning Commission’s determination exempting the project from further environmental review. APPEAL ANALYSIS Both the Zoning Administrator and Planning Commission determined that the project was categorically exempt from CEQA. Projects exempt from CEQA are not subject to further environmental review through the preparation of a (Mitigated) Negative Declaration or Environmental Impact Report. Determination of the appropriate level of environmental review is made by the lead agency, which is typically the reviewing body that makes the final discretionary action on a project. 12 A recent amendment to Public Resources Code Section 21151 allows an individual to appeal a project’s CEQA determination when the final action is made by a non-elected, decision-making body. In this case, the Planning Commission’s CEQA determination may be appealed to the City Council. However, the scope of review on the appeal is limited only to the CEQA determination. The underlying Use Permit is not before the City Council. As stated, the Planning Commission relied on the Class 3, Categorical Exemption, which includes exemptions for projects involving the construction and installation of small new facilities and equipment. The full text of this exemption is provided in Attachment G of this report. Reliance on this exemption was appropriate. The proposed project involves the installation of a new wireless communication facility, including antennas and associated mechanical equipment on the roof of an existing commercial building. The proposed facility is small in area and location, is incidental to the existing uses on the property, and has been conditioned to demonstrate compliance with Federal Communication Commission regulations pertaining to radio frequency electromagnetic fields. Moreover, the proposed facility is completely screened from the public right of way behind a parapet wall designed to match the existing parapet, with the exception of a two foot square, flush mounted antenna on the penthouse of the five story building. 13 There are instances in which categorical exemptions cannot be utilized. The appellant contends that the Planning Commission erred in its application of the environmental exemption determination citing potential health-related impacts and cumulative impacts upon the community. The appellant also states that the due process rights of area residents was violated as a result of the City’s public notification process. As typical with wireless communication facilities, the Zoning Administrator and the Planning Commission on appeal seek to balance a carrier’s need for an expanded wireless service with the potential negative visual impacts commonly associated with this type of installation. Section 704 of the Telecommunications Act of 1996 (TCA) prohibits local government from denying an application to construct a cell site based upon the environmental effects of radio frequency (“RF”) emissions from the proposed wireless site: No State or local government or instrumentality thereof may regulate the placement, construction, and modification of personal wireless service facilities on the basis of the environmental effects of radio frequency emissions to the extent that such facilities comply with the [Federal Communication] Commission’s regulations concerning such emissions. The FCC and the California Public Utilities Commission (CPUC) verify compliance with applicable regulations, and accepted health safety standards. Compliance with these standards is required prior to facility operation. The City requires as a standard condition of approval prior to the issuance of a building permit, documentation from the wireless carriers noting approved compliance with FCC regulations. 14 While the appellant acknowledges the federal preemption, concern is expressed that the Planning Commission should have required demonstration of FCC compliance prior to rendering an environmental determination. This approach, however, is not necessary. The Planning Commission conditioned project approval on demonstrating FCC compliance prior to issuance of a building permit. As all wireless communication facilities in the City have complied with the FCC regulations, it is anticipated that the subject applicant will be able to achieve compliance. Indeed, the applicant has submitted a copy of the FCC form that it intends to submit as part of the CPUC and FCC approval process. That form is included with this report as Attachment F. The appellant maintains however that the City’s cultural landscape, character, aesthetics, view shed, historic resources, and pedestrian/vehicle safety would be compromised by this and other foreseeable projects. The appellant calls the City’s piecemeal approach to wireless communication facilities inconsistent with other City policies that aim at protecting the environment, improving the quality of life, and promoting sustainability. This assertion, however, is unfounded. Each application evaluated by the Zoning Administrator, or Planning Commission on appeal, is specifically analyzed for conformance with applicable rules and regulations, including conformance with the City’s General Plan. Many of these applications are also reviewed by the City’s Architectural Review Board to ensure facility screening is compatible with existing site improvements. Projects, in part, are conditionally approved or denied based on an 15 applicant’s ability to design a project in compliance with the City’s General Plan. There is no evidence to support that pedestrian or vehicle safety has been compromised, historic resources adversely altered or the cultural landscape changed as a result of any wireless communication facility in the City. This is particularly the case for the subject application, which is essentially entirely screened from view. The only visible element of the facility would be a two foot square panel antenna on the penthouse wall atop a five story building. This antenna would also be painted to match the color of the existing building. No change in height, bulk, mass or character of existing structure will occur as part of this project. Associated mechanical would be housed within the existing building. Based on this design, the proposed project will not have any individual or cumulative impact upon the City’s physical or cultural environment. The contention of the Planning Commission’s environmental determination is not supported by substantial evidence linking the project to any significant environmental impact, as required by CEQA. Regarding the due process concerns expressed in the appeal statement, the project was properly noticed pursuant to Santa Monica Municipal Code Section 9.04.20.22.050. Evidence of proper noticing is available in the administrative record. Moreover, this challenge is actually directed at the underlying decision to grant the Use Permit, a decision that is not before the City Council. Conclusion The Zoning Administrator and Planning Commission on appeal approved the subject Use Permit application based on findings and subject to conditions. The Planning 16 Commission’s determination that the project was categorically exempt from CEQA was subsequently appealed based on concerns related to potential significant environmental impacts. Analysis of the appeal statement, the project, and the information provided by the applicant shows that the categorical exemption issued for this project is appropriate. CEQA STATUS The project is categorically exempt from the provisions of California Environmental Quality Act (CEQA) pursuant to Section 15303, Class 3 of the State Implementation Guidelines in that the project involves the installation of limited new commercial wireless communication antennas and associated mechanical equipment on the roof of an existing commercial building. The wireless facility is in compliance with FCC requirements regarding wireless facilities. In addition, the proposed facility has been designed to limit any visual impacts by being located behind the existing parapet walls. PUBLIC NOTIFICATION Pursuant to Municipal Code Section 9.04.20.22.050, notice of the public hearing was mailed to all owners and residential and commercial tenants of property located within a 300 foot radius of the project and published in the “California” Section of The Los Angeles Times at least ten consecutive calendar days prior to the hearing. A copy of the notice is contained in Attachment A. BUDGET/FINANCIAL IMPACT The recommendation presented in this report does not have any budget or fiscal impact. 17 RECOMMENDATION It is recommended that the Council deny the appeal (04APP004) and uphold the Planning Commission’s CEQA determination exempting the proposed project from further environmental review, based upon the following finding: FINDING(S) 1.
