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.

The 750 linear feet of sidewalk, ranging in width from 4 to 10 feet, will connect the Palace of the Fine Arts and Tunnel Tops.

Project Number21-004
Project NameMountain Lake Pathway Replacement
Planning DistrictSouth Hills
Project TypeLandscaping/Site Work
CE AppliedLandscaping and landscape maintenance
CE Date11/9/2020
Project Description
The City and County of San Francisco will remove and replace a 115-foot long, 7-foot wide spur trail at Mountain Lake Park that allows park users to access the lake edge from the DeAnza Trail above. The concrete pathway and stone curbwall has failed due to extensive erosion and is no longer usable. The pedestrian pathway will be replaced with a raised wooden, ADA accessible boardwalk with a maximum slope of less than 5 percent. The boardwalk will be supported on helical metal piles, 3-1/2 inches in diameter and a maximum of 14 feet deep, screwed into place to minimize soil removal and construction impacts, and mitigate future potential erosion issues. The disturbed area will be revegetated with plants from the Presidio Nursery.
 
Project Number21-003
Project NameArguello Gate Limited Landscape & Visitor Improvements
Planning DistrictSouth Hills
Project TypeLandscaping/Site Work
CE AppliedLandscaping and landscape maintenance
CE Date10/30/2020
Project Description
Minor improvements will be made to the area recently disturbed by the recent PG&E construction (project 19-053). The improvements will include landscape plantings in the bare areas, one or two benches, and a two-sided kiosk to help orient park visitors entering the Arguello Gate. The kiosk will be set in a 190 square-foot, fully accessible concrete pad. The concrete pad will require a small amount of grading of the existing low berm. All fill created by the grading can be reused on site. Plantings will include a mix of drought tolerant, exotic and native plants. Once established, the plants will require only a minimum of supplemental irrigation. The existing irrigation system will be rehabilitated in advance of planting.

Minor alterations in deck design will prolong the life of the decks. The bottom rail along the inside of railing will be raised to prevent moisture retention on decking and posts and concrete footing will be located closer to the buildings. Additional flashing will be used to prevent rotting. Fencing around trash enclosures will be replaced in-kind.
 
Project Number21-001
Project NameRevisions to COVID-19 Emergency Order
Planning DistrictPresidio-wide
Project TypeSpecial Events
CE AppliedSpecial events, public assemblies, and meetings
CE Date10/8/2020
Project Description
In response to the COVID-19 outbreak and the local shelter in place orders, in March 2020, the Trust issued the COVID-19 Declaration of Emergency declaring an emergency for Area B of the Presidio (project 20-032). To respond to the public health emergency, protect the health and safety of the Presidio community, and to be consistent with the recent City and County of San Francisco (CCSF) mandates, the Trust also issued successive orders to establish closures and public use limits in Area B. The Trust has been closely monitoring the CCSF orders, and accompanying directives and guidance, to generally align the operation of activities in the Presidio with that of the CCSF. The latest order sets forth public use limits and closures that are consistent with the CCSF’s effective order(s) which are expected to be revised periodically. The order adopts restrictions addressing the particular facts and circumstances in the Presidio, which are necessary to respond to the public health emergency as it is evolving, and eases restrictions on activities with a lower risk of spreading the virus. This includes permitting of commercial activities, camping at Rob Hill, ball field uses, summer and day camps, school instruction, and small and large gatherings for celebrations and meetings in compliance with preventive measures for the safety of persons within the Presidio.

Project Number20-050
Project NameFormer Commissary Building 610/Parking Lot Improvements
Planning DistrictCrissy Field
Project TypeLandscaping/Site Work
CE AppliedLandscaping and landscape maintenance
CE Date9/23/2020
Project Description
The former Commissary (non-historic building 610 currently occupied by Sports Basement) parking lot is visually intrusive, overaccommodates parking demand, and consumes 3.7 acres of high value open space. This project will redesign the parking lot and modify the building to enhance the site’s visual character, create a more inviting and pedestrian-friendly environment, and add to the area’s overall environmental health while maintaining sufficient parking supply for nearby users. Approximately 2.4 acres of the existing parking lot will be replaced with a new turf meadow and other landscape features. The meadow will be ringed by group and family-scaled picnic areas, seating and a network of paths. New landscaping will feature native dune scrub and drought-tolerant non-native plantings. Parking for approximately 96 vehicles will be retained on the southern third of the project site and approximately 45 new parking spaces will be provided along the north side of the building and in the footprint of the approximately 5,000 square-foot, former Commissary’s refrigerator wing (non-historic building 653), which will be demolished. Modifications to building 610 include reorienting the building’s entrance from the east to the north side of the building facing Mason Street, expanding the public restrooms, and other select interior tenant improvements.
