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 Number20-044
Project NameMountain Lake Overflow Pipeline Repair
Planning DistrictSouth Hills
Project TypeInfrastructure
CE AppliedUpgrading or adding utilities
CE Date7/9/2020
Project Description
This project will construct a new overflow structure on the west side of Mountain Lake along Highway 1 before it discharges into a downstream overflow pipeline, which is in disrepair and will be rehabilitated. The new overflow structure will allow the Trust to control and maintain the lake water level to protect the lake’s ecosystem and City and Caltrans assets (namely, Mountain Lake Park and Park Presidio, respectively). The overflow pipeline conveys flows out to a San Francisco Public Utilities Commission (SFPUC) junction known as the Volcano Structure in Lobos Creek Valley (Area A), then to the SFPUC Richmond Transport, and finally to the SFPUC Oceanside Water Pollution Control Plant. Drainage conveyance in the overflow pipe will be improved by rehabilitating approximately 1,700 linear feet of existing pipe in poor condition by using both cured-in-place pipe (CIPP) rehabilitation and pipe bursting from the inlet at Mountain Lake to the vicinity of the Volcano Structure. Pipeline repair operations will require temporary site access through Lobos Creek Valley that contains dune habitat occupied by the endangered San Francisco lessingia (consultation with the U.S. Fish and Wildlife Service concluded with a “no jeopardy” biological opinion). Upon project completion, Caltrans will eliminate Highway 1 runoff discharges into Mountain Lake by decommissioning the existing outfalls that drain highway runoff into the west bank of Mountain Lake and connecting the Highway 1 drainage system directly to the upgraded overflow pipe. Stormwater runoff from Highway 1 has historically caused pollution, sedimentation and erosion problems at Mountain Lake and this project will ultimately complete the environmental remediation work that has been done at Mountain Lake.

CE Date7/8/2020
Project Description
Inclusive Capital Partners (tenant) will make improvements in historic building 1170 (1919) of the recently rehabilitated Gorgas Warehouses (project 19-047)  to accommodate office use. A new partition wall will separate the west end of the building to create a sub-tenant space and a shared corridor for restroom access. Ten enclosed office spaces, two conference rooms and a break room will be constructed along the perimeter of the warehouse. The height and glazing of enclosed offices will retain the sense of open space characteristic of the warehouse. New ductwork will be completed to service the enclosed spaces. The tenant will occupy building 572 until work is completed.
 
Project Number20-043
Project NameCavalry Bowl Reforestion Phase 1
Planning DistrictCrissy Field
Project TypeTrees
CE AppliedRemoval of non-threatened or endangered species
CE Date7/2/2020
Project Description
This project will restore an over-mature and senescent 0.97-acre stand of approximately 25 Monterey pine and Monterey cypress trees within the VMP Historic Forest Management Zone near U.S. Highway 101. The trees are being removed at this time to minimize hazards to a proposed multi-use trail through the stand as part of the Doyle Drive rehabilitation project. Most of the woody material will be removed from the site and stumps will be ground below grade. Roughly 400 yards of Trust-made compost will be applied as soil amendment, and a drip irrigation system will be installed to establish between 125 and 150 Monterey pine and Monterey cypress tree seedlings. The site will be maintained for a period of 5 to 8 years before periodically thinning to arrive at 30 to 50 trees per acre when mature. Customary measures will be in place to minimize environmental impacts including stormwater management and erosion control, traffic management and hauling restrictions, public outreach and signage, and lead in soils sampling.

Measures include signage, hand sanitizer stations and plexy-glass sneeze guards. Signs placed throughout the buildings will direct movement to accommodate for social distancing, and will provide social distancing, face covering and handwashing instructions and reminders. Freestanding and wall-mounted hand sanitizer stations will be installed throughout the buildings. Plexi-glass sneeze guards will be installed at customer help desks and receptions areas.
 
Project Number20-042
Project NameParkwide Pavement Rehabilitation and Maintenance
Planning DistrictPresidio-wide
Project TypeTransportation/Parking
CE AppliedRepair of roads and parking facilities
CE Date6/4/2020
Project Description
The Trust has adopted a strategic goal to reduce deferred maintenance. This paving project is the first step towards that goal for roadways and parking lots. The project will rehabilitate and perform preventative maintenance on about a quarter (7.9 miles) of the park’s roadways and five parking lots. Fresh pavement will provide the opportunity to restripe the roadways for new biking and walking facilities, increase bike lane widths, upgrade bike lanes to separated bike lanes, improve crosswalks and implement traffic calming. The changes will improve the bicycle and walking network around the park, further increasing alternative transportation options for visitors and tenants. The roadways and parking lots were selected through an optimization process that considered current pavement condition, facility lifecycle, and available budget.
 
Project Number20-041
Project NameRevisions to COVID-19 Emergency Order
Planning DistrictPresidio-wide
Project TypeSpecial Events
CE AppliedSpecial events, public assemblies, and meetings
CE Date6/2/2020
Project Description
This Order further revises closures and public use limits in the Presidio to respond to the evolving public health emergency and to manage the park consistent with the City’s most recent public health orders. The Order restricts all outdoor recreation activities to only those permitted in the City’s Shelter in Place Order No. C19-07e. The Order requires the public to wear face coverings while outdoors consistent with the CCSF’s Face Coverings Order C19-12b.  The Order also authorizes “Presidio Slow Streets” (program) to reduce vehicular traffic and create more open space for the public to engage in physical distancing during the shelter in place orders. The program is consistent with the City’s measures to create limited “Slow Streets” throughout San Francisco and replaces the pilot “Presidio Loop” program (project 20-034). The program consists of a mixture of closing select lightly-used streets, closing select streets used regularly for cut-through traffic, and creating slow streets and shared spaces on streets with increased use by Presidio users walking and riding bicycles. Limited vehicle access for residents, tenants and delivery and emergency vehicles will still be allowed in the slow street zone. The program will begin on Saturday, June 6, 2020, and continue while the shelter in place order is in effect, or until further notice. The closures and restrictions will be in effect 7 days per week, 24 hours per day. Staff will monitor the effectiveness of the program to ensure the transportation benefits of the program are not undermined by crowding or congregation. Based on that monitoring, the Trust may make adjustments to sections of roadways that are closed or restricted, adjust the times or duration of the program, or terminate the program as deemed necessary for the health, safety and welfare of the public. The public will be notified with posted signage, advance messaging and information on the Trust’s website. Roadway signage, traffic cones and barriers will be installed to alert park users of the closures.
