Project Summary

placement of the nodes and antennas, resulting in the proposed network design herein.

The anticipated technologies and frequencies that will be deployed are 700 Mhz LTE, 850 Mhz CDMA, EDVO and UMTS, and 1900 Mhz CDMA, EDVO, LTE, and UMTS. In order to accommodate these WSP requirements, each of the three node placements will require two antennas at each site The pole design for the one freestanding nodej y

This design submission focuses on the ExteNet Systems, Inc. (“ExteNet”) proposed temporary three node Outdoor Distributed Antenna System (ODAS) Installation as requested by at least two Wireless Service Providers (WSPs) to provide licensed spectrum commercial wireless coverage and capacity on the West campus. Two of the antenna sets will be located on the parking garage (refer to locations 1 and 2 on page 7) d h h ill b f di l j h h f

antennas at each site. The pole design for the one freestanding node pole involves placement of the two antennas on a support arm with the equipment placed in a ground mounted enclosure. The garage mounted nodes will each have two antennas on the roof, connected back to secure enclosures mounted on interior garage walls, designed to minimize visual impact.

The RF Compliance and Assessment Report has analyzed the emissionand the other antenna set will be a freestanding pole just to the north of Building 38 (refer to location 3 on page 19). The hub location that aggregates the signals from all the node locations will be located on a concrete pad near the existing campus power facility (refer to location 4 on page 23). The temporary nature of the installation may be reconfigured in accordance with the campus long term development. The footprint of the ODAS may need to grow in the future due to

The RF Compliance and Assessment Report has analyzed the emission levels of the proposed ODAS antennas and finds them well within the safety standards as required by current FCC regulations, with the follow exception: based on worst‐case predictive modeling, the worst‐case emitted power density will exceed the FCC’s general public limit at the rooftop of the parking garage near the East and West sector locations. Once the antennas are installed and operational at the sites the The footprint of the ODAS may need to grow in the future due to

The ExteNet design focuses on providing outdoor commercial wireless coverage and capacity for the Phase 1 occupancy area previously approved by NCPC. The proposed coverage area for the ODAS comprises

The proposed ODAS incorporates similar design characteristics found in other historic or visually sensitive deployments. The basic concept involved in these deployments is to conceal or limit the visual impact of the placement of the ODAS node equipment, antennas, and the hub site, given the RF, topology and WSP carrier customer requirements. The

Project Report (continued) Relationship to the Master Plan The design of the Phase 1 Outdoor Antenna Installation is consistent with the intent of the approved St. Elizabeths Master Plan and is in accordance with the St Elizabeths Design Guidelines Parcel 3 Site Development with the St. Elizabeths Design Guidelines Parcel 3 Site Development Standard:

• Large‐scale communication equipment will be positioned so as to minimize visibility from within the campus or from vantage points

minimize the visual impacts to the extent possible. The RF report and visual quality analysis is included in the submission package. The FEIS for the DHS Headquarters Consolidation at St. Elizabeths dated November 7, 2008 and the Final Master Plan Amendment FEIS for the DHS Headquarters Consolidation at St. Elizabeths dated March 2, 2012 can be referenced at www.stelizabeth'sdevelopment.com/document center

• Potential locations for equipment are near Interstate 295. Any communication equipment situated along the Interstate should be

should be considered adverse. Since the installation of antennas and poles were already considered in the Master Plan and EIS, GSA and the DCSHPO agree that this adverse effect should be considered part of the larger effects of the redevelopment of the campus that have already taken into account and no individual Memorandum of Agreement or additional mitigation is required.

Construction completion: Autumn 2013

Project BudgetAs this project is being funded by ExteNet and the WSPs, there is not anticipated to be any funding required from any Federal government

Floodplain Management and Protection A review of the floodplain maps issued by FEMA in September 2010 for the District of Columbia indicate that the limit of work for the antennas is outside both the 100‐and 500‐year floodplain; no additional documentation is needed to comply with EO 11988source.

Environmental Documentation (EIS) Visual impacts and the radio frequency emissions impacts from antennas were discussed in the 2008 Final Environmental Impact Statement (FEIS). According to the FEIS, GSA would employ the practice of “prudent avoidance” to reduce the exposure of workers and the public to RF fields.

documentation is needed to comply with EO 11988.

To ensure that this is accomplished a RF EME Compliance and Assessment Report was prepared for this project. The FEIS also discussed minimizing the visual impacts of any antennas placed on site and the locations of the antennas included in this submission were selected to
