PROJECT OVERVIEW The property at 847 Deerfield Road is currently improved with a Metro Storage facility approved by Ordinance 2016-055. The petitioners, Bob Heilman on behalf Metro Storage LLC are requesting approval of a special use to sell packing and shipping materials at the existing storage facility at 847 Deerfield Road. The 150 square foot retail space will be located within the existing 1,000 square foot office space. The Zoning Code in the Industrial district does not list incidental retail uses to a storage facility as either a permitted or a special use.

EXSITING LAND USE AND ZONING: The property is improved with a Fire Station building currently located in the Industrial District. COMPREHENSIVE PLAN: The approved Village Comprehensive Plan calls for this property and the immediate neighborhood to be Industrial. PROJECT BACKGROUND Village of Buffalo Grove is requesting to replace an existing ground mounted communication antenna located at Fire Station 27, located at 100 Half Day Road. The communication antenna will be used for emergency communications at the Fire Stations 26 and 27, and for automated water meter reading at Public Works. The existing 80 foot tall ground mounted communication antenna on the north side of fire station 27 is in poor condition, and hence needs to be replaced. The proposed height of the communication tower measures 100 feet. In contrast to Fire Station 26 which is located in a residential district; Fire Station 27 is located in the Industrial district and Public Utility Facility (Public Safety Communication Antenna) is a permitted use up to 60 feet in height. Pursuant to the Municipal Code, Public Utility Facility (Public Safety Communication Antenna) must not exceed the maximum permissible height of 60 feet. 2.2.a Packet Pg. 14 At t a c h m e n t : S t a f f R e p o r t ( C o n s i d e r H e i g h t V a r i a t i o n f o r a P u b l i c S a f e t y C o m m u n i c a t i o n A n t e n n a t o E x c e e d t h e M a x i m u m H e i g h t ) PLANNING & ZONING ANALYSIS Communication Antenna Use  The communication antennas will continue to be used for emergency communications at the Fire Station 26 and 27, as well as for automated water reading at Public Works.  The communication antennas will not be used for any commercial use.  Unlike the antenna at Fire Station 26 which is located in a residential district, Fire Station 27 is located in an Industrial district by which Public Utility Facility (Public Safety Communication Antenna) is a permitted use up to 60 feet in height. Existing Communication Antenna  The existing ground mounted communication antenna is located on the north side of Fire Station 27 building, and was constructed in 1991 as shown in a red dot in Image A.  The communication antenna is 80 feet tall.  This existing communication antenna is located approximately 200’ from Easton Avenue.  This existing communication antenna is presently in a poor structural condition and has to be replaced as it poses a safety concern. Proposed Location and Height of communication tower  The Village of Buffalo Grove is proposing to replace a communication antenna right behind the Fire Station 27 building on the North side, with a new communication antenna which will be offset by approximately 9 feet to the east of the existing communication antenna as shown in a blue dot in Image A.  The proposed communication antenna will be setback approximately 191 feet from the Easton Avenue which the meets setback requirements.  The communication antenna is proposed to be 100 feet for more reliable coverage, and to meet Buffalo Grove’s growing tree canopy.

VARIATIONS REQUESTED A height variation from the Zoning Ordinance Section 17.32 to allow for the installation of a Public Utility Facility (Public Safety Communication Antenna) to exceed the maximum permissible height of 60’. DEPARTMENTAL REVIEWS Village Department Comments Engineering The Engineering Department has reviewed the proposed communication antenna and have no concerns with the proposed location of the communication antenna. SURROUNDING PROPERTY OWNERS Pursuant to Village Code, the contiguous property owners were notified and a public hearing sign was posted on the subject property. The posting of the public hearing sign and the mailed notifications were completed within the prescribed timeframe as required. As of the date of this Staff Report, the Village has received 5 calls inquiring about the proposed ground mounted communication tower at the subject property, however no concerns were raised. STANDARDS The Planning & Zoning Commission is authorized to grant variations on the following criteria: 1. The proposed variation will not alter the essential character of the neighborhood; 2. There are practical difficulties or particular hardships in carrying out the variation request; 3. The proposed variation will not be detrimental to public health safety and welfare. The petitioner has provided a written response to the standards for a variation which are included in this packet. STAFF RECOMMENDATION Village staff recommends approval for the purpose of installation of a communication antenna to exceed 40 feet in height (maximum allowed 60 feet in height) from the ground level: 1) The proposed communication antenna shall be installed in accordance with the documents and plans submitted as part of this petition. ACTION REQUESTED The Planning & Zoning Commission (PZC) shall open the public hearing and take public testimony concerning the variation. The PZC shall make a final decision on whether or not to approve the variation. 2.2.a Packet Pg. 16 At t a c h m e n t : S t a f f R e p o r t ( C o n s i d e r H e i g h t V a r i a t i o n f o r a P u b l i c S a f e t y C o m m u n i c a t i o n A n t e n n a t o E x c e e d t h e M a x i m u m H e i g h t ) VILLAGE OF BUFFALO GROVE An Internationally Accredited Public Works Agency Since 2004 MEMORANDUM DATE: December 1, 2019 TO: Planning and Zoning Commission FROM: Rati Akash, Village Planner Mike Skibbe, Deputy Director of Public Works SUBJECT: Village Antenna Towers at Fire Station 26 & 27 OVERVIEW The Village of Buffalo Grove is seeking an amendment to the special use for the replacement of two existing antenna towers in Fire Station 26 and Fire Station 27 respectively. The two proposed towers would be 100 foot tall, self-supporting, ground mounted antennas. The communications devices mounted on the towers would only be Village specific devices, and no commercial use devices are proposed. The towers are critical to the connectivity of emergency communications at the Fire Stations, as well as for our automated water meter reading antenna in Public Works. SITE SPECIFICS Fire Station 27 – 100 Half Day Road The existing tower at Fire Station 27 is a, 80 foot tall self-supporting tower mounted just North of the Fire Station itself. The tower was constructed with the new Fire Station in 1991. It is in poor overall condition, with deteriorating structural members and a leaning concrete foundation pad. This tower supports both the computer connection to Village Hall for onsite personnel, and emergency communication radio equipment. The new tower would increase in height by 20 feet to clear the increase in height of the tree canopy throughout the Village. It would be constructed just north of the existing tower, both to limit the change in view as well as to allow the new tower to be built before the existing tower is removed. Please see the attached diagrams for specific measurements. Fire Station 26 – 109 Deerfield Parkway The existing tower at Fire Station 26 is an 80 foot tall, roof mounted antenna tower with guy wire support system. It is mounted on the roof of the station which was constructed in 1981, and last revised by increasing its height due to tree canopy in 2008. The guy wire anchor system to the roof deck no longer meets industry standard, and rather than try to modify an aged tower, we propose to move it to a more typical ground mounted, self-supporting tower design. 2.2.b Packet Pg. 17 At t a c h m e n t : P l a n S e t ( C o n s i d e r H e i g h t V a r i a t i o n f o r a P u b l i c S a f e t y C o m m u n i c a t i o n A n t e n n a t o E x c e e d t h e M a x i m u m H e i g h t ) VILLAGE OF BUFFALO GROVE An Internationally Accredited Public Works Agency Since 2004 A similar roof mounted tower, at Village Hall, failed in 2009 by falling off the roof. The Village Hall tower was moved to the ground in a similar replacement project. We want to replace this tower and avoid any potential of a similar fate. The proposed tower would be mounted on the ground just south of the Fire Station, as close as feasible to its current location. Since the 80 foot tall antenna tower was mounted to the top of the structure, the overall height at this location will be similar with the 100 foot tall ground mounted antenna. We believe the overall appearance will be similar, if not less impactful to the neighborhood. The new tower will not require the guy-wire support system which added to the overall appearance of the existing tower. Please see the attached diagrams with specific dimensions. REQUESTS Fire Station 26 Petition for an amendment to the special use Ordinance No. 90-83 for the preliminary plan approval of fire station 26. Petition for variation to Zoning Ordinance Section 17.32 allow for the installation of self- supporting communication antennas which exceeds the maximum permissible height of 60’. Fire Station 27 Petition for an amendment to the special use Ordinance No. 90-43 for the preliminary plan approval of fire station 27. Petition for variation to Zoning Ordinance Section 17.32 allow for the installation of self- supporting communication antennas which exceeds the maximum permissible height of 60’. The Village of Buffalo Grove is seeking to replace two existing antennas in both Fire Station 26 and Fire Station 27, with two new proposed self-supporting ground mounted antennas which would be 100 foot tall.

The purpose of this Exclusion Analysis is to evaluate whether the proposed wireless communications installation meets the established regulatory criteria necessary to qualify for an exemption from the Section 106 review process. PROJECT DESCRIPTION The proposed wireless communications installation will consist of replacing an existing tower facility. The existing tower facility was constructed in 1991 and is located adjacent to the north of an existing building. Specifically, the existing 80-foot self-support tower will be replaced by a 100-foot self-support tower directly east of the existing tower to be removed. According to information provided by the Client, the existing 80-foot tower has one 15- foot antenna mounted on top for an overall height of 95 feet above ground level (AGL). The new tower will maintain the existing antenna at 95 feet and mount a new whip antenna at a top-height of 105 feet AGL. No new ground disturbance outside the existing lease area is planned for this tower replacement. Please refer to the attached plans for a full description of the proposed installation. REGULATORY OVERVIEW Pursuant to Federal Communications Commission (FCC) rules implementing the National Environmental Policy Act (NEPA; 47 CFR 1.1306, Note 1), the preparation of an Environmental Assessment (EA) is not required for the mounting of antenna(s) on an existing building or antenna tower, unless the proposed facility (i) may affect districts, sites, buildings, structures or objects, significant in American history, architecture, archaeology, engineering or culture, that are listed, or are eligible for listing, in the National Register of Historic Places, or (ii) would result in human exposure to radiofrequency radiation in excess of applicable health and safety guidelines. Further, under FCC NEPA Rules (47 CFR §1.1320), the Nationwide Programmatic Agreement for the Collocation of Wireless Antennas (Collocation Agreement; March 16, 2001 as amended 2016), and the Nationwide Programmatic Agreement for Review of Effects on Historic Properties (NPA; September 2004), certain undertakings which meet applicable exclusionary criteria are exempted from the Section 106 review process. 2.2.b Packet Pg. 25 At t a c h m e n t : P l a n S e t ( C o n s i d e r H e i g h t V a r i a t i o n f o r a P u b l i c S a f e t y C o m m u n i c a t i o n A n t e n n a t o E x c e e d t h e M a x i m u m H e i g h t ) SECTION 106 REVIEW EXEMPTIONS Antenna Installation Based on project details provided by the Client, EBI evaluated whether the proposed antenna installation qualifies for an exemption from Section 106 Review, by evaluating it against the criteria set forth under the following: Exclusion B of the 2004 NPA Exemption from Section 106 review for construction of a replacement tower Based on the results of EBI’s analysis, the proposed installation does meet the applicable exclusionary criteria set forth under the above-referenced regulatory exemption(s). As such, Section 106 review is not required. Please refer to the attached checklist for a complete summary of EBI’s analysis of the proposed installation against the specific criteria set forth under the above-referenced regulatory exemption. RADIO FREQUENCY RADIATION An evaluation to determine whether radiofrequency (RF) emissions standards are met was not included as part of this Report. EBI understands that the Client will evaluate the proposed installation to ensure it will not result in human exposure to RF emissions in excess of the applicable FCC standards, as outlined in 47 CFR §1.1307(b). CONCLUSIONS Based on the project details provided by the Client, and the research and analysis completed by EBI, the proposed installation does meet the exclusionary criteria set forth in one of the existing regulatory exemptions from Section 106 review. As such, the proposed installation is recognized to have minimal or no adverse effect on historic properties and Indian religious sites or culturally significant properties, and further consultation or review under Section 106 is not required.

The two proposed towers would be 100 foot tall, self-supporting, ground mounted antennas. The communications devices mounted on the towers would only be Village specific devices, and no commercial use devices are proposed. The towers are critical to the connectivity of emergency communications at the Fire Stations, as well as for our automated water meter reading antenna in Public Works. SITE SPECIFICS Fire Station 27 – 100 Half Day Road The existing tower at Fire Station 27 is a, 80 foot tall self-supporting tower mounted just North of the Fire Station itself. The tower was constructed with the new Fire Station in 1991. It is in poor overall condition, with deteriorating structural members and a leaning concrete foundation pad. This tower supports both the computer connection to Village Hall for onsite personnel, and emergency communication radio equipment. The new tower would increase in height by 20 feet to clear the increase in height of the tree canopy throughout the Village. It would be constructed just north of the existing tower, both to limit the change in view as well as to allow the new tower to be built before the existing tower is removed. Please see the attached diagrams for specific measurements. Fire Station 26 – 109 Deerfield Parkway The existing tower at Fire Station 26 is an 80 foot tall, roof mounted antenna tower with guy wire support system. It is mounted on the roof of the station which was constructed in 1981, and last revised by increasing its height due to tree canopy in 2008. The guy wire anchor system to the roof deck no longer meets industry standard, and rather than try to modify an aged tower, we propose to move it to a more typical ground mounted, self-supporting tower design. 2.3.b Packet Pg. 74 At t a c h m e n t : P l a n S e t ( C o n s i d e r S p e c i a l U s e i n t h e R D i s t r i c t a n d H e i g h t V a r i a t i o n f o r P u b l i c S a f e t y C o m m u n i c a t i o n A n t e n n a ) VILLAGE OF BUFFALO GROVE An Internationally Accredited Public Works Agency Since 2004 A similar roof mounted tower, at Village Hall, failed in 2009 by falling off the roof. The Village Hall tower was moved to the ground in a similar replacement project. We want to replace this tower and avoid any potential of a similar fate. The proposed tower would be mounted on the ground just south of the Fire Station, as close as feasible to its current location. Since the 80 foot tall antenna tower was mounted to the top of the structure, the overall height at this location will be similar with the 100 foot tall ground mounted antenna. We believe the overall appearance will be similar, if not less impactful to the neighborhood. The new tower will not require the guy-wire support system which added to the overall appearance of the existing tower. Please see the attached diagrams with specific dimensions. REQUESTS Fire Station 26 Petition for an amendment to the special use Ordinance No. 90-83 for the preliminary plan approval of fire station 26. Petition for variation to Zoning Ordinance Section 17.32 allow for the installation of self- supporting communication antennas which exceeds the maximum permissible height of 60’. Fire Station 27 Petition for an amendment to the special use Ordinance No. 90-43 for the preliminary plan approval of fire station 27. Petition for variation to Zoning Ordinance Section 17.32 allow for the installation of self- supporting communication antennas which exceeds the maximum permissible height of 60’.
