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 Number18-017
Project NameWright Loop Light Fixture Replacements
Planning DistrictFort Scott
Project TypeInfrastructure
CE AppliedUpgrading or adding utilities
CE Date2/9/2018
Project Description
The five pedestrian-scale light fixtures (pole and luminaire) along Wright Loop are either missing or in a state of disrepair. The Trust will install five new Spectra fixtures similar to those used on Lovers’ Lane (project 09-115). The fixtures will be energy efficient LEDs with full cutoffs (no uplight) to prevent light trespass into the adjacent forest. The fixtures will also be outfitted with sensors that allow the light to be operated at two intensities.
 
Project Number18-016
Project NameLED Streetlight Conversion
Planning DistrictPresidio-wide
Project TypeInfrastructure
CE AppliedUpgrading or adding utilities
CE Date2/5/2018
Project Description
The Trust is replacing its approximately 800 streetlight fixtures with ultra-efficient, light emitting diode (LED) fixtures. Of the 800 fixtures, approximately 700 are cobra head style and 100 are pedestal type. The LED fixtures will improve lighting conditions throughout the Presidio for pedestrians, bicyclists and drivers. The new streetlights will consume on average 50 percent less energy than the current streetlights, thereby reducing electricity costs and the Presidio’s environmental footprint. Trust crews will remove the “head” of the existing streetlight and replace it with a new LED luminaire, leaving the existing pole and crossarm untouched. The LED luminaires will have a correlated color temperature (CCT) of 3,000° Kelvin (K). All fixtures will be fully cut off fixtures compliant with International Dark Sky Association recommendations and those of the American Medical Association. The changeover is expected to be completed by the end of 2020.
 
Project Number18-015
Project NameSimonds Loop Island Vegetation Clearing
Planning DistrictEast Housing
Project TypeMaintenance
CE AppliedLandscaping and landscape maintenance
CE Date2/1/2018
Project Description
As recent as 1997, Simonds Loop Island was much more open than it is presently, likely due to the routine mowing of the less steep areas by the U.S. Army. Mostly in response to recurring problems with homeless camps in the 6.2-acre island, selected vegetation will be removed in two areas within the island, and at a recently discovered camp just down slope from Quarters 1. Initial clearing efforts will focus on a number of invasive plants that have altered the character of the island over the past few years. Targeted plants include Canary Islands St. Johnswort (Hypericum canariensis), which covers roughly 20 percent of the island and its unique character creates a dense canopy creating a barren plant free ground-plain (perfect for camping and hiding out), cotoneaster and black acacia, which contribute to the incredible density. Current efforts are expected to better reveal several desirable plant species, both natives and exotics, and Works Progress Administration-era stone walkways, stairs and drainages.
 
Project Number18-014
Project NameBuilding 684 (Substation 680) Transformer Replacement
Planning DistrictCrissy Field
Project TypeInfrastructure
CE AppliedRoutine maintenance and property and resource management
CE Date1/17/2018
Project Description
The transformer that serves the Fort Scott electric distribution area is beyond its service life and needs to be replaced. This project will remove and replace one distribution transformer and one distribution switch inside Building 684. The enclosure block wall facing Park Boulevard will be removed and replaced in-kind at project completion. Work activities will occur outside of the tree protection zone of two nearby mature cypresses. Traffic controls will be implemented for short durations as necessary for equipment removal and replacement. Affected tenants will be notified in advance of two short duration power outages occurring overnight to the service area at the beginning and end of the project. The oil inside the existing equipment will be handled and disposed of according to its waste classification.
 
Project Number18-012
Project NameBattery Sherwood Bluff Stabilization
Planning DistrictCrissy Field
Project TypeLandscaping/Site Work
CE AppliedLandscaping and landscape maintenance
CE Date1/11/2018
Project Description
Over the past several years, the slope behind NHL-contributing building 643 (built 1923) has experienced landslides of varying degrees of severity without much repair or reworking. During the winter of 2016-17, approximately 75 cubic yards of soil slid down the slope and collected at the rear (south) elevation of building 643 (NPS-owned building in Area B).  Surface flow at the top of the slope may have contributed to the landslides, along with overgrown conditions on the slope face that have hidden washouts. This project will provide emergency stabilization measures to address slope failures. Equipment to be mobilized on site includes an excavator, tracked skidsteer, water tote, and hydro-mulch trailer. Soil that slid to the area behind building 643 will be tested and stored for the Tunnel Tops project if clean or otherwise disposed at a permitted, offsite landfill in accordance with state and federal law. A temporary gabion wall approximately 6 feet tall and 54 feet long will be installed at the toe of the slope to buttress remaining failing soil. Crews will hydro-mulch and replant the cleared slope face in accordance with an approved revegetation plan. Access and staging of the work, which is expected to take approximately one week, will be coordinated with Caltrans and NPS. A long term engineered solution is being developed.
 
Project Number18-013
Project Name Kashmir Cypress Plantings Near Building 558
Planning DistrictLetterman
Project TypeLandscaping/Site Work
CE AppliedLandscaping and landscape maintenance
CE Date1/9/2018
Project Description
Four Kashmir Cypress (Cupressus cashmeriana) in the now larger open area west of building 558 will be planted after the recent loss of a mature coast live oak. The planting is consistent with the Presidio Promenade ornamental planting, both historic and recent, in the vicinity of building 558. Trust Landscape crews will plant the 15-gallon trees in the immediate area of the downed oak. The excavation will be by hand and to a depth of no more than 12 inches. Trust Remediation and Archaeological staff will be consulted prior to the work.
 
Project Number18-011
Project NameAdditional Security Measures at Quarters 1
Planning DistrictEast Housing
Project TypeLandscaping/Site Work
CE AppliedLandscaping and landscape maintenance
CE Date12/12/2017
Project Description
NHLD-contributing Quarters 1 (built 1943) is set back from Simonds Loop, surrounded on two sides by dense and extensive vegetation, and adjacent to the city. This setting warrants additional security measures beyond those constructed last year (project 17-043) to deter would-be intruders. The project will install a short (approximately 200 feet) section of 6-foot high, black vinyl coated, chain link fence along the western perimeter of the residence. The intent is to eliminate the easy passage from Shafter Road into the area in front of the guesthouse/garage by forcing pedestrians down toward the more public areas viewable from Simonds Loop before they are able to approach the home. As little vegetation will be removed as possible, though one downed tree may have to be cut back to accommodate the installation.
 
Project Number18-010
Project NameInstallation of Barn Owl Boxes at Fort Scott
Planning DistrictFort Scott
Project TypeIPM
CE AppliedRemoval of non-threatened or endangered species
CE Date12/5/2017
Project Description
This project attempts to reduce pest problems by attracting more rodent predators to the Presidio. Two barn owl boxes will be installed in the Fort Scott neighborhood. The boxes will be made of unpainted wood and to the specifications recommended by the Hungry Owl Project (Marin, CA). The boxes will be monitored for establishment of owl nesting. If nesting occurs, barn owl feeding habits will be observed, and any reduction in rodent-related complaints from neighborhood tenants will be noted. Evidence from barn owl diet and work order patterns will be used to determine if barn owl boxes are an appropriate addition to the rodent control work already being done by the Trust’s integrated pest management (IPM) program.
 
Project Number18-005
Project NameGreenwich Gate Re-Opening and Presidio Promenade Trail Extension
Planning DistrictEast Housing
Project TypeLandscaping/Site Work
CE AppliedTrail development, relocation, or maintenance
CE Date11/28/2017
Project Description
Much of the 2.1-mile Presidio Promenade multi-use trail connecting the Golden Gate Bridge to the Greenwich Gate has been completed as envisioned in the 2003 Presidio Trails and Bikeways Master Plan. The 535 feet east of the Letterman/Lombard intersection is one of the few remaining segments. This project will create a new gate for pedestrians and bicyclists at Greenwich Street and build the easternmost 535 feet of the multi-use trail. The project is anticipated to improve safety and convenience for pedestrians, cyclists and motor vehicle drivers. Pedestrians entering or leaving the Presidio through the Greenwich Gate will experience fewer conflicts with vehicles compared to the Lombard Gate. The new gate will also be more direct for Presidio residents, visitors and employees walking to/from the MUNI 41 and 45 routes, which terminate on Lyon Street immediately south of Greenwich Street. Cyclists could enter the Presidio directly from San Francisco Bike Route 6 on Greenwich Street. Reduced pedestrian and bicyclist traffic at the Lombard/Lyon intersection at the Lombard Gate will improve the operation of the all-way stop intersection for both vehicular traffic and transit (PresidiGo and MUNI 43). The gate will reestablish an opening in the wall at Greenwich Street that existed 1892-1950, but at approximately half the width of the 26-foot wide historic opening. The gate opening will be just wide enough to accommodate a 10-foot wide path with 2-foot wide shoulders. The project will also include crosswalks and other crossing improvements at Ruger Street and Letterman Drive, retaining walls at the gate and along Lombard Street near Letterman Drive, lighting, signage, striping and access controls, irrigation system upgrades and landscaping. Five trees will be removed.
 
Project Number18-008
Project NameUpper Simonds Loop Concrete Walkway Repairs
Planning DistrictEast Housing
Project TypeLandscaping/Site Work
CE AppliedRoutine maintenance and property and resource management
CE Date11/27/2017
Project Description
Concrete repairs to the walkways, landings and sidewalks around five Upper Simonds Loop duplexes (510 – 514) are needed to address uneven walking surfaces. The concrete elements around these buildings are original to the construction of the homes, dating from 1940 as part of a Works Progress Administration project. Front step landings along with concrete walkways at the side and rear elevations will be removed and replaced in-kind to eliminate tripping hazards. This work will include necessary grading, dowels and rebar to prevent future settling of the new concrete, and installing curb ramps for accessibility along the public sidewalks in front of the units.
