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 Number17-050
Project NameBuilding 86 Suite 200 Minor Tenant Improvements
Planning DistrictMain Post
Project TypeRehabilitation/TI
CE AppliedRehabilitation or improvement of historic properties
CE Date9/1/2017
Project Description
The existing tenant of suite 200, building 86 (former barracks building, built 1862) will make minor improvements to accommodate its changing needs. The scope includes the removal of non-historic finishes, walls and light fixtures. Additional work items include the construction of a closet, selective window replacement, selective new data and power floor monuments, and replacement of the existing HVAC system using existing penetrations.
 
Project Number17-049
Project NamePlaygroup Site (Buildings 1818-1819) Storm Drainage Improvements
Planning DistrictPHSH
Project TypeInfrastructure
CE AppliedUpgrading or adding utilities
CE Date8/24/2017
Project Description
The storms of the last two winters have proved that the soil on the north side of rehabilitated building 1819 (project 14-029) percolate very poorly. The yard drains in the playground back up and pond, and it appears that the ground on the north and east sides of the building becomes saturated and contributes to the leakage through the foundation walls and into the basement offices. This drainage improvement project will install a solid wall 6-inch PVC storm drain pipe that will allow an existing 6-inch perforated infiltration pipe to drain directly into a combined sewer/storm drain manhole. Other improvements include installing a sump pump in the basement floor, waterproofing the north side of the building, replacing planters that have been trampled by children with decomposed granite, adding pavers, and filling in a small area with concrete to match the existing concrete sidewalk.
 
Project Number17-035
Project NameLiggett Avenue Connector Walk
Planning DistrictEast Housing
Project TypeRecreation
CE AppliedTrail development, relocation, or maintenance
CE Date8/22/2017
Project Description
The section of Liggett Avenue between Sumner Avenue and Lovers Lane is an important vehicle and pedestrian connection from Presidio Boulevard into the East Housing area. The road does not have sidewalks on either side and immediately adjacent to the curblines are slopes or narrow shoulders such that most pedestrians choose to walk in the roadway. This project will add a code compliant sidewalk along the western side of the road allowing for pedestrians to safely traverse the area from Lovers Lane to the existing sidewalk in front of residential building 540. Two mature eucalyptus trees will be removed.
 
Project Number17-045
Project NameFootpath behind Building 44 to Ecology Trail
Planning DistrictMain Post
Project TypeRecreation
CE AppliedTrail development, relocation, or maintenance
CE Date8/22/2017
Project Description
The education programs in buildings 49 and 50 occasionally take groups of school children from their facility up to the Ecology Trail. The most direct and car-free connection is a social trail up the slope between buildings 44 and 47. The trail behind building 47 becomes very steep as it passes over a storm water berm. The trail can be very slippery, especially during the wet months, resulting in accidents going up and down the slope. This project realigns the trail and avoids the steep slope by running in back of building 44 and then diagonally up the hill to the Ecology Trail. The trail will be no wider than a few feet, and will be either bare earth or woodchips. A small number of volunteer acacias will be removed and some low hanging branches of nearby trees will be pruned prior to construction.
 
Project Number17-048
Project NamePortal Temporary Art Installation
Planning DistrictMain Post
Project TypeMiscellaneous
CE AppliedInstallation of signs, displays, and kiosks
CE Date8/22/2017
Project Description
Portals is an ongoing global project created by Shared Studios, an art and technology collaborative organization. A Portal is a repurposed shipping container, painted gold and equipped with audiovisual immersive technology, enabling users to come face to face with another Portal user in one of over 20 locations in 11 countries. Portals are facilitated by a curator and translator, and the goal of the experience is to encourage park users to think about the park in comparison to other places where Portals are located and to experience the Presidio as a space to explore new cultures and ideas. This project will reinstall the Portal currently at Crissy Field to Pershing Square for a one-month period beginning late September. The Portal will be powered by a solar unit (courtesy of Luminalt) and back-up generator, and will be connected to the internet via a separate internet service unit. Visitation will be scheduled through a free reservation system, with walk ups managed by the curator. Only 10 people will be permitted in the Portal at a time and each session will last 20 minutes. The Portal will have an accessible ramp. Hours of operation will vary depending upon time zone/program at other sites.
 
Project Number17-043
Project NameQuarters 1 Security Measures
Planning DistrictEast Housing
Project TypeLandscaping/Site Work
CE AppliedReplacement of minor structures and facilities
CE Date8/14/2017
Project Description
Quarters 1 is an occupied NHL-contributing residential building (built 1943) on Upper Simonds Loop.  The residents have recently experienced break-ins at the main residence and the adjacent garage/in-law unit, which dates to 2007 (project 07-014). In response, the residents will add a new metal security fence to the top of the historic concrete wall at the rear of the property, and a new glass railing at the top of the nonhistoric in-law unit.
 
Project Number17-044
Project NameWest Washington Residential Window Replacement
Planning DistrictSouth Hills
Project TypeRehabilitation/TI
CE AppliedRehabilitation or improvement of non-historic properties
CE Date8/14/2017
Project Description
The West Washington residential units (1401-1443) are an NHL-noncontributing neighborhood of multi-family buildings clustered on Washington Boulevard and Battery Caulfield Road. The aluminum windows in the units have reached the end of their serviceable life and are failing, causing moisture infiltration, mold and difficulty of operation. After evaluating several alternatives, the Trust determined that the most cost-effective, environmentally sustainable and easy to maintain replacement window is a weatherized white vinyl slider. This project will replace all windows in the neighborhood as a pilot to determine how the new windows will perform. Future window replacements at similar units in the Presidio will be evaluated based on the performance of the window type and appropriateness vis-à-vis building contributing or non-contributing status.
 
Project Number17-046
Project NameNew Lab Shed at Native Plant Nursery
Planning DistrictFort Scott
Project TypeMiscellaneous
CE AppliedReplacement of minor structures and facilities
CE Date8/14/2017
Project Description
The Trust currently uses space in an existing building at the Native Plant Nursery to conduct lab tests for pathogens. Staff wish to conduct the testing in a separate space with lighting and a sink. This project will install a pre-fabricated 10-foot by 16-foot shed for use as a lab at the south end of the nursery. The shed will be placed on a poured concrete slab, will be sustainably built of green materials (FSC certified lumber, mixed-source recycled metal and materials throughout, optimized prefabricated production) and will meet Trust building codes.
 
Project Number17-042
Project NameBuilding 5 Phase II Tenant Improvements for Educational Use
Planning DistrictMain Post
Project TypeRehabilitation/TI
CE AppliedRehabilitation or improvement of historic properties
CE Date7/31/2017
Project Description
The project will complete necessary occupancy requirements at building 5 (Officers’ Housing, 1862) for the German School of Silicon Valley. Previously the tenant performed minor upgrades to accommodate temporary school occupancy for the remainder of the school year (project 17-013). This work will expand upon that scope and include the opening of a previously sealed doorway on the second floor, connecting the north and south halves of the building, and the installation of metal guardrails in front of a code-deficient stair balustrade. The project will also include the construction of a wood ramp at the rear of the building to accommodate ADA access.

Project Description
The project will create another teeing surface and expand the yardage of the 13th Tee using residual soil from the MacArthur Meadow wetland restoration (Project 15-002) stored near the hole. The work will include shaping the remaining soils and adding irrigation. The teeing area will be sodded for more immediate use and the slopes will be hydro-seeded with a no mow fescue blend identical to what is used on other areas inside the course. No native species will be affected.
