Categorical Exclusions

​​​​To further transparency and openness in its implementation of the National Environmental Policy Act (NEPA) process, the Presidio Trust documents its Categorical Exclusion (CE) determinations involving the categories of actions identified in Section 1010.7 of the Trust’s NEPA regulations. The CE database may be searched by planning district, project type, CE applied, or the year initiated.​​ The database is updated approximately monthly. For additional information on the Trust’s NEPA compliance program, email N2@presidiotrust.gov.

Project Description
Project Number22-001
Project NameAT&T Armistead Road Cell Tower Modifications
Planning DistrictFort Scott
Project TypeCell Sites
CE AppliedLeasing or sale of real or personal property
CE Date10/21/2021
Project Description
AT&T Mobility Services, LLC (applicant) will replace some of its antennas to enhance service and provide 5G technology on an existing 60-foot tall steel monopole (project 09-030) located at their base station on the east side of US Highway 101 about 1,200 feet southeast of the Golden Gate Bridge toll booths near Armistead Road. The work will include moving and replacing 6 antennas on new mounts no less than about 48 feet above ground, replacing 3 remote radio units and adding 3 diplexers at the base of the pole on the ground.  The rest of the work, which mainly involves replacing the battery system, will take place in the existing equipment shelter within the fenced enclosure. Due to their mounting location and height, the antennas will not be accessible to unauthorized persons. The facility will comply with Federal Communications Commission (FCC) standards for limiting public exposure to Radio Frequency (RF) energy.
 
Project Number22-002
Project NameSubstation 107 Upgrade
Planning DistrictMain Post
Project TypeInfrastructure
CE AppliedImprovements to meet disabled access requirements
CE Date10/14/2021
Project Description
Historic building 107 (Substation, 1911), which supplies approximately half of the Presidio’s electrical energy requirements, will be upgraded to meet current industry standards and safety codes. The 4kV switchgear and distribution transformers are beyond their serviceable lifespan and will be replaced. A steel brace system will be installed on the building’s interior to meet seismic requirements. A window at the northwest corner of the building will be enlarged to become a doorway and pushbars will be installed at all exit doors to meet egress requirements. The new doorway will retain the height and width of the historic window, maintaining the historic fenestration pattern.

Project NameVerizon Shafter Road Cell Site Modifications
Planning DistrictSouth Hills
Project TypeCell Sites
CE AppliedLeasing or sale of real or personal property
CE Date9/30/2021
Project Description
Verizon Wireless (applicant) intends to remove 6 existing antennas on an existing 80-foot tall wireless monopole (project 10-056) and replace these antennas with a newer model of panel antenna that combines the previous and new technologies (5G) for faster and more efficient capacity in the surrounding area. Part of the installation will require replacing and/or adding some of the ancillary equipment within a fenced equipment space abutting the monopole so they are compatible with the new antennas. The modifications will replace outdated technology to secure faster speeds and performance for their network and the direct vicinity of the facility. The unmanned wireless facility is in operation 24 hours a day. The modifications will take place over approximately 21 days with a small equipment staging area abutting the facility. The facility will comply with prevailing Federal Communications Commission (FCC) Radio Frequency (RF) Safety Guidelines.

Project Number21-042
Project NameRehabilitation of East Mason Street Warehouses for Office/Commercial Use
Planning DistrictCrissy Field
Project TypeRehabilitation/Base Bldg
CE AppliedRehabilitation or improvement of historic properties
CE Date9/16/2021
Project Description
Historic buildings 1182 through 1188 (Warehouses, 1917-1919) comprise a distinctive row of seven mostly identical structures that align with Mason Street at the Marina Gate. The buildings have undergone some prior alterations that have added partitions and connections to adjacent buildings to facilitate U.S. Army storage and office uses but retain moderate to high levels of integrity. With the exception of a previous office and warehouse use in two of the buildings, the warehouses have been mostly vacant since 1994 and are in fair condition. This project will rehabilitate the buildings and associated site area for office/commercial occupancy by one or multiple tenants, consistent with Trust long range planning objectives, current applicable building standards and market factors. The project will result in a structurally upgraded “warm shell” with common core(s) and systems. All interior and exterior character defining features will be retained, and new elements (building systems, common area cores, restrooms, storefront entries, circulation elements, exterior ramps and raised decking) will be compatibly designed. New window and skylight openings will re-establish existing openings that were covered over during the U.S. Army era and allow for additional natural light in select areas. Existing historic windows will be retained and repaired. All work will comply with Secretary of Interior Standards for Rehabilitation, Presidio Trust Management Plan planning principles, and project-specific rehabilitation guidelines and treatment recommendations. Building-specific improvements to follow to accommodate future tenants will be subject to additional environmental review. The site’s vehicular circulation and parking lot (for 210 cars) were previously evaluated and constructed as part of the Presidio Parkway project.

Project NameBuilding 36 Bay School Tenant Improvement
Planning DistrictMain Post
Project TypeRehabilitation/TI
CE AppliedRehabilitation or improvement of historic properties
CE Date8/31/2021
Project Description
The San Francisco Bay School (building 35 tenant) wishes to expand school use into historic building 36 (Barracks, 1885). The project represents a change in occupancy type from office to education, which will require two new structural walls and seismic reinforcement of existing walls. Historic wall finishes will be removed, stored and reinstalled. New office and classroom spaces will be created by removing existing non-historic partition walls and adding two new partition walls. A single-use restroom and two drinking fountains will be installed on the second floor. Non-historic doors will be modified with vision glass for classroom spaces. Mechanical, electrical, and fire protection work is limited to minor relocation and realignments to support the new layout.
