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.

CE AppliedLandscaping and landscape maintenance
CE Date11/14/2022
Project Description
Contractors under Trust oversight will perform installation and repair of erosion and sediment control and housekeeping measures on an as-needed basis parkwide. A typical task order would be installing wattles, minor re-grading with hand-tools, applying compost and seeding to eliminate preferential flow paths in a defined area.

Project Number23-005
Project NameBuilding 39 South Exterior Exit Ladder Installation
Planning DistrictMain Post
Project TypeRehabilitation/Base Bldg
CE AppliedRehabilitation or improvement of historic properties
CE Date11/8/2022
Project Description
Proposed interior tenant improvements to suite 212 of historic building 39 (Barracks, 1939) (project 22-031) necessitate a second means of egress. Reconfiguring the building’s interior would require extensive alterations that would adversely affect character defining features. Therefore, the Trust will install a retractable emergency exit ladder on the building’s exterior, accessible through an existing window. The ladder will be fastened to the east facing wall adjacent to a chimney stack. A basement window well will be covered with a grate to create a safe landing pad. Landscaping will be altered to create a pathway from the ladder to the sidewalk, which is currently blocked by shrubs.
 
Project Number23-007
Project NameLyon Vallejo Boundary Wall Renewal
Planning DistrictEast Housing
Project TypeLandscaping/Site Work
CE AppliedLandscaping and landscape maintenance
CE Date11/8/2022
Project Description
A portion of the historic stone boundary wall at Lyon and Vallejo streets collapsed in 2021. The Trust will reconstruct the entire width of Vallejo Street with modifications to the original design necessary to improve the stormwater drainage that likely caused the collapse. New concrete piers will be drilled and a new concrete ledge and drainpipe will be installed behind the wall. The new section of wall will be built using shotcrete and a stone veneer that will match the appearance of the historic wall.
 
Project Number23-006
Project NameBuildings 39, 86, 87 Telephone Entry Card Access Upgrade
Planning DistrictMain Post
Project TypeMaintenance
CE AppliedRoutine maintenance and property and resource management
CE Date11/8/2022
Project Description
Wireless card readers are used on the Trust's commercially leased spaces to ensure that only tenants and authorized visitors have access to buildings. The Trust will upgrade card readers at 22 access doors on historic buildings 39 (Barracks, 1940), 86 (Barracks, 1862) and 87 (Barracks, 1862). Existing conduit will be reused to the greatest extent possible, but the footprint of the upgraded equipment will vary from the existing. In building 39, additional telephone entries and panic door hardware will be added on the rear of the building. In buildings 86 and 87, two new telephone entries with card readers will be added to the front of the main lobby and rear access doors. Additional card readers will be added to the exterior bathroom doors. Cabling will follow the existing pathways to the closest extent possible.
 
Project Number23-004
Project NameBuilding 135 Golden Gate Club Elevator Replacement
Planning DistrictMain Post
Project TypeRehabilitation/Base Bldg
CE Applied
CE Date11/7/2022
Project Description
The Trust will replace the elevator in historic building 135 (Noncommissioned Officers’ Club), which has reached the end of its useable life. The existing elevator uses a hydraulic system to move people and materials from the basement to the second floor. The hydraulic system  has become increasingly difficult to maintain because parts are now obsolete.  A new elevator will reuse the existing elevator shaft but will use electric machinery. The associated electrical equipment for the new elevator will be installed in the elevator control room and basement. No exterior work will be performed.
 
Project Number23-002
Project NameBattery Electric Bus Charging Station Installation
Planning DistrictMain Post
Project TypeInfrastructure
CE AppliedUpgrading or adding utilities
CE Date11/1/2022
Project Description
The Trust will install a charger and supporting transformer to service its new battery electric bus as part of the PresidioGo fleet. The transformer will replace an existing piece of equipment on a new concrete pad in the lawn area east of the Presidio Fire Station. The charger will be located on a new concrete pad adjacent to the south edge of the parking lot north of the Presidio Fire Station near the Presidio Transit Center.  The work will include excavating the concrete pads, installing equipment and connecting to underground utilities.
 
Project Number23-003
Project NameBuilding 1471 Central Magazine Door Retrofit
Planning DistrictFort Scott
Project TypeRehabilitation
CE AppliedRehabilitation or improvement of non-historic properties
CE Date11/1/2022
Project Description
The Trust uses a portion of the historic Central Magazine (building 1471, 1938,  artillery storage) for hazardous material storage prior to shipping for disposal. Its passive ventilation system, a series of small tubes cast into the ceiling, is insufficient to ventilate the space in its current use. The Trust will install a custom perforated metal door to the opening to improve indoor air quality. The door will be secured to the concrete with a custom latch designed to integrate into the original blast door latches without modifying the original blast doors. Installation will require drilling anchors into the concrete wall on the north side of the southernmost doorway of the structure.
 
Project Number23-001
Project NameEco-Counter Traffic Counter Installation
Planning DistrictPresidio-wide
Project TypeTransportation/Parking
CE AppliedRepair of roads and parking facilities
CE Date10/25/2022
Project Description
The Trust will install a combination of pedestrian, bicycle and/or vehicle traffic counters at five park entry locations and two Golden Gate Bridge, Highway & Transportation District locations. The automated counters will make it possible to understand how many people visit the park each day and what gates are being used most often by park users. The data will be used to capture seasonal trends, plan future transportation infrastructure, and communicate with the public. The project also includes installing pole-mounted cameras with the capacity to count and classify bicycles, pedestrians and vehicles. Work is to be completed by an electrical contractor with experience installing traffic signal systems.

Verizon Wireless presently has twelve antennas installed at the top of the lattice tower. T-Mobile will add 6 new antennas and 6 corresponding radio units to the tower and an equipment area adjacent to the north side of the existing Verizon Wireless equipment area at the base of the tower. This area will be approximately 280 square feet enclosed by a 6-foot chain-link fence and will include two concrete pads on which equipment cabinets and a generator will be installed. All necessary power and telecommunications infrastructure servicing the cell site will be placed inside the equipment area and fed from the existing infrastructure on site via new conduits.
