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 Number19-004
Project NameDigital Information Kiosk at Transit Center (Building 215)
Planning DistrictMain Post
Project TypeSite Furnishings
CE AppliedInstallation of signs, displays, and kiosks
CE Date10/9/2018
Project Description
The outdated information kiosks within the park need replacing to match the Trust’s existing sign standards. There is a desire for a digital kiosk at the Transit Center (building 215), the arrival hub for transit riders and visitors. The kiosk will display a transportation feed of live departure times, a map with destinations and/or a feed of the Presidio’s Instagram images, and will direct people to the Visitor Center (building 210) for more orientation and event type of information. The existing four-sided kiosk will be removed and two digital panels will be installed on the exterior of the building under the eaves to avoid exposure to the harsh marine environment and cluttering the sidewalk. The Transit Center is the only location identified for digital information.
 
Project Number18-051
Project NameCell Site #27 A-D (Near Sports Basement) Relocation
Planning DistrictCrissy Field
Project TypeCell Sites
CE AppliedLeasing or sale of real or personal property
CE Date10/2/2018
Project Description
Four separate temporary monopoles located east of building 610 (Sports Basement) need to be relocated in light of the impending Tunnel Tops project. This project will remove the four monopoles and replace them with two 55-foot monopoles to the west of the building. The project will allow the carriers (Verizon, Sprint, AT&T and T-Mobile) to maintain, if not improve, their current coverage along the Presidio Parkway as well as areas south of the tower locations. Each monopole will provide enough space for two carriers. The foundation will include 18 cell blocks (each measuring 7 feet by 7 feet by 2 feet) to support the construction and installation of both monopoles and all ground equipment. Fiber and power to the site will share a joint trench approximately 490 feet long and 3 feet deep. A six-foot tall chain-link fence will be installed around the cell blocks. One contractor will be responsible for all work relative to the construction of the monopoles and the utility infrastructure. After construction is complete and the site is operational, the licensed area will remain an unmanned facility that requires regular maintenance (generally once per month by each carrier).

Project Number18-059
Project NameHalleck Street Preservation Maintenance
Planning DistrictMain Post
Project TypeMaintenance
CE AppliedRoutine maintenance and property and resource management
CE Date9/12/2018
Project Description
Currently vacant Halleck Street buildings 223 (Warehouse, 1897), 227 (Warehouse, 1897), 228 (Bakery, 1909) and 229 (Pastry Bakery, 1897) will be mothballed to protect the historic buildings in anticipation of future leasing. The project includes roof repair/replacement, structural upgrades, exterior envelope stabilization and removal of non-historic elements.  The roofs on buildings 227, 228 and 229, having reached the end of their serviceable life, will be fully replaced in kind.  Plywood sheathing, rigid insulation and interior structural blocking will also be added.  On building 227, non-historic elements including dormers, galvanized security grates on the windows, and exterior heater vent stacks will be removed and openings patched.  Historic skylights will be retained and flashing repaired.  Because the newer roof on building 223 only requires an overlay, non-historic dormers will remain for now, pending future full replacement of the roof.  Window openings along Halleck Street will be covered in plywood.  Non-historic additions to buildings 229 and 227 will remain pending future rehabilitation of the buildings.
