Categorical Exclusion Determinations
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 Number: 15-005
Project Name: Building 385 Landscape Rehabilitation
Planning District: Main Post
Project Type: Landscaping/Site Work
CE Applied: Landscaping and landscape maintenance
CE Date: 12/12/2014
Project Description:
This project will rehabilitate a small (3,000-square foot) lawn on the north side of building 385 (built 1955) along Moraga Avenue and west of the entrance walk. The work includes removing the lawn and altering existing irrigation to support an assortment of groundcovers and shrubs similar to the existing plantings, and three or four pine trees aligned with Moraga Avenue. The row of pine trees is consistent with the Community District treatment recommendations from the Main Post Cultural Landscape Report. Originally the trees were Monterey pine (Pinus radiata), which is not readily available as a disease resistant variety. Cluster pine (Pinus piaster), which is very similar looking to Monterey pine and has recently been approved for use on the Presidio, will be used in its place. A total of 40 new plants, including the row of pines, will be arranged on-site. Additional plantings could fill in the site should funds become available.

Project Number: 15-006
Project Name: Fog Harvest Pilot Project
Planning District: Fort Scott
Project Type: Research/Testing
CE Applied: Research, monitoring, inventorying, and information gathering
CE Date: 12/12/2014
Project Description:
Fog harvesting is a technique of pulling water out of the air under favorable climatic conditions. It has been studied and used in foggy regions of the world for several decades, notably in Chile. Using a small-scale fog collection system, the Trust will investigate whether the typical fog that reaches the Battery Saffold/Battery Dynamite area could be captured to supplement water used to irrigate compost windrows at the Presidio compost facility between Battery Saffold and Battery Dynamite. The pilot will involve installation of up to 3 small-scale fog collectors, each consisting of a 1m by 1m mesh screen that is attached on either end to two poles. The poles will rest on top of the ground and be secured using guy wires, and sand bags if necessary. The amount of water collected from the screens will be monitored daily. At the end of the pilot, several variables will be accessed: the amount of water collected; an extrapolation of the potential amount of water collected by a larger scale system; the water storage capabilities of the site; the visual impact of the pilot screens; and the educational potential of this water.

Project Number: 15-004
Project Name: Building 215 Transit Café Renovation
Planning District: Main Post
Project Type: Rehabilitation/TI
CE Applied: Rehabilitation or improvement of non-historic properties
CE Date: 11/25/2014
Project Description:
This project will remodel the Transit Café at non-historic building 215 (built 2005). The remodel includes new equipment for self service foods, a new small storage room, changing lighting fixtures, repainting, new tables and chairs (interior and exterior), new umbrellas and removal of one small planted area to allow for clearer access to the main entry. The modifications will improve the flow within the café, and provide more food options and expedited customer service to its patrons. In order to provide continuity of food service during the 6- to 8-week construction period, the catering truck currently at the Golden Gate Club will be temporarily relocated to the grassy area west of the café. The catering truck will offer coffee, beverages and a limited food menu from early morning to early afternoon. The perimeter of the catering truck will be supported with 1-inch plywood to protect the roots of the adjacent stand of Cypress trees.

Project Number: 15-003
Project Name: Addition of Café at SenSpa Building 1161
Planning District: Letterman
Project Type: Rehabilitation/TI
CE Applied: Rehabilitation or improvement of historic properties
CE Date: 11/18/2014
Project Description:
Building 1161 is a former warehouse (circa 1919) rehabilitated into a spa by the existing tenant, SenSpa, in 2005 (05-015). This project will convert an existing lounge and meeting space into a café that will serve beverages and pre-packaged food. All additions, including a food service counter, sink, refrigerator, partition wall with shoji screen door with panels, and new flooring, will be installed in a manner that is fully reversible. Selective demolition and infill of non-historic walls will be necessary to accommodate or remove doors. The project will not alter or damage existing historic finishes including original warehouse walls (behind new sheetrock), rafters and wood plank flooring.

Project Number: 15-001
Project Name: Building 1756 New Warehouse at Trust Corporate Yard
Planning District: South Hills
Project Type: Building Use
CE Applied: Rehabilitation or improvement of non-historic properties
CE Date: 10/23/2014
Project Description:
The Trust currently stores building maintenance and repair materials in building 643 in the Crissy Field district (Area B). Building 643 must be vacated, which requires the storage operation be moved to a new facility. The fenced area north of and abutting non-historic building 1752 (former Army motor pool maintenance shop, part of an isolated complex of buildings constructed in 1970) within the Trust corporate yard will allow the Trust to consolidate materials delivery and storage operations with existing warehousing operations. The area is currently occupied by a non-historic 2,134 square-foot metal carport structure, which will be replaced by a new 3,400 square-foot warehouse (the PTMP permits new small structures and replacement construction in the South Hills “to serve the management needs of the park”). The pre-engineered, clear-span building is designed to maximize interior efficiency and optimize truck unloading access. Construction will include the abandonment of an existing cast-iron water lateral and a new connection to the water main, demolition and recycling of the existing carport and asphalt-concrete paving, new footings and slab, and erection of the building. Electrical, heating, fire suppression, fire alarm and access control system, loading door and main door, and other features will be installed in the new warehouse. The new warehouse will be clad in metal siding with a roof-type compatible with the adjacent building, and dark-sky compliant light fixtures will be used. All work will conform to current applicable Trust codes, guidelines and standards.

Project Number: 14-046
Project Name: New Entrance to Building D Restaurant in Letterman Digital Arts Center
Planning District: Letterman
Project Type: Rehabilitation/TI
CE Applied: Rehabilitation or improvement of non-historic properties
CE Date: 10/21/2014
Project Description:
This project will construct a new entrance to the currently vacant first floor restaurant in building D at the Letterman Digital Arts Center. The primary entrance addition to the facility will include a ramp, stair, canopy and patio. The patio will be constructed around an existing redwood tree, which will be protected during construction.

Project Number: 14-016
Project Name: Mountain Lake Fish Eradication
Planning District: South Hills
Project Type: Vegetation Restoration
CE Applied: Removal of non-threatened or endangered species
CE Date: 10/1/2014
Project Description:
As part of an adaptive management plan to reintroduce native vegetation and wildlife in Mountain Lake, the Trust will apply a botanical fish toxicant to the lake to remove all fish from the lake including sediment-foraging carp and predator bass. The presence of these and other invasive fish in the lake prevents the successful reintroduction of native species and the overall restoration of the lake. The Trust has unsuccessfully used mechanical means such as nets and electrical current to eradicate fish from the lake. CFT Legumine, which contains the active ingredient Rotenone, will be used as the fish toxicant. Rotenone is a botanical material that degrades very quickly in water. A single treatment of CFT Legumine applied during the fall of 2014 will likely be successful in eradicating all fish from the lake. The lake will be monitored for Rotenone following treatment.

Project Number: 14-049
Project Name: Ralston Sanitary Sewer Upgrades
Planning District: Fort Scott
Project Type: Infrastructure
CE Applied: Installation of underground utilities
CE Date: 9/26/2014
Project Description:
This project addresses deficiencies within the Trust’s sanitary sewer system serving the west side of Fort Scott to support planned redevelopment of buildings in the district. The work scope entails repairing and/or replacing the sanitary sewer on Ralston Street from building 1203 bisecting Storey Avenue and extending north on Miller Road. Work will be performed with a typical excavation and trench approach or with a minimally invasive pipe-burst method which reduces the amount of excavation necessary. The interiors of existing manholes will be rehabilitated and spot repairs made at discrete pipe locations. Portions of the project boundaries are within a known LUC site. Excavated soil will be tested for potential contaminants and reused as backfill subject to approval by the Trust Remediation Program Manager or disposed at a permitted, offsite landfill in accordance with state and federal law. Tree protection measures as outlined by the Presidio Trust Forester will be followed for trees adjacent to the excavation areas.
