Project Description
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.

Project Type: Rehabilitation/TI
CE Applied: Rehabilitation or improvement of historic properties
CE Date: 9/24/2014
Project Description:
The back porch of building 58 (Funston Avenue Officer Family Housing, built 1885) is a secondary space whose size and footprint has been altered over time to accommodate changing needs, and was last rebuilt 8 years ago as part of a neighborhood rehabilitation project (06-039). This project will enlarge (by 42 square feet) and enclose the porch for additional storage space. The work includes the selective removal of the existing deck, construction of the new deck, three new footings, an enlarged landing, reconstructed stairs and railings, an extended shed roof to match existing roof in dimension and profile, and enclosure porch with simple 1/1 wood frame windows and a door. Work will match existing construction and appearance and will be performed by Trust crews and contract workers with Trust oversight.

Project Number: 14-045
Project Name: Fort Scott Parking Regulations at Ralston and Upton
Planning District: Fort Scott
Project Type: Transportation/Parking
CE Applied: Repair of roads and parking facilities
CE Date: 8/25/2014
Project Description:
As Fort Scott becomes more active, parking management is necessary to ensure that parking supply remains adequate into the future. In 2013, parking regulations were implemented along Storey Avenue, in the parking lot in front of Building 1208, the parking lot serving the Log Cabin (13-038), and again in 2014 at the CNG lot located off of Lincoln Boulevard (14-014). This project will install parking machines to vend parking permits and associated regulatory signage along Battery Wagner Road and along Upton Avenue and Ralston Avenue between buildings 1227 and 1230. Parking along Battery Wagner Road will be regulated every day from 8am-6pm for Zones P and 9, which will allow Storey Avenue residents to continue to use this area for overflow parking. The rest of the area will be regulated similar to other areas of Fort Scott (every day from 8am-6pm) and zoned as Zone 9.

Project Number: 14-041
Project Name: North Fort Scott Residential Neighborhood Landscape Enhancements
Planning District: Fort Scott
Project Type: Landscaping/Site Work
CE Applied: Landscaping and landscape maintenance
CE Date: 8/25/2014
Project Description:
This neighborhood landscape enhancement project is part of ongoing efforts to upgrade all residential neighborhood landscapes to support Trust sustainability, aesthetic and planning goals. The scope of work includes select tree removal (16 mature eucalyptus trees in the Ramsel Court area), new concrete patios associated with most buildings, and the addition of ornamental plantings at the entrys and in areas visible from the streets. The design will build upon the mid-century modern aesthetic of the the structures and will include plants from Australia and South Africa. While the non-historic North Fort Scott neighborhood (2-story, multi-unit residential buildings constructed in 1970) does not contribute to the NHLD, its context within the larger NHL and adjacent VMP areas has been taken into consideration in the design approach. The work will be coordinated with planned landscape replacement/enhancement along the Doyle Drive construction corridor. Landscaping of Lendrum Court will be reviewed as a separate project following completion of soil remediation.

Project Number: 14-042
Project Name: Soil Sampling Workplan for Lendrum Court
Planning District: Fort Scott
Project Type: Remediation
CE Applied: Improvements to meet disabled access requirements
CE Date: 8/25/2014
Project Description:
Trenching and sampling of the Lendrum Court residential neighborhood is required to determine the extent of Army-era waste debris present. Sampling will allow for the development of remedial alternatives and designs to address the debris in a manner protective of human health and the environment per guidance by the Department of Toxic Substance Control. Approximately 20 test pits will be excavated near the 20 residential buildings around Lendrum Court to evaluate the extent of debris present. Test pits are planned to be approximately 18 inches wide, up to 8 feet long, and 5 feet deep. Test pits will be excavated using a subcontractor-operated mini-excavator. Soil will be returned to the test pits and compacted by wheel rolling on the same day as it is excavated. To allow access for test pits, undergrowth and small brush in the dense forest north of and around Lendrum Court will be cut to approximately 6 inches above ground surface. This will allow visual observation of ground, distinctions in topography, and exposure of debris, while still leaving roots and some ground cover in place to limit soil erosion. Trees will remain in place to provide canopy and visual screening for residents. Tree protection measures will be incorporated in the vegetation removal plans. Tenants and neighbors have been consulted in public meetings, public outreach is ongoing, and the project is posted on the Trust’s website.

Project Number: 14-044
Project Name: Sand Import and Storage at Nike Site
Planning District: PHSH
Project Type: Miscellaneous
CE Applied: Routine maintenance and property and resource management
CE Date: 8/25/2014
Project Description:
Dune sand is being excavated from the CPMC hospital site at Cathederal Hill in San Francisco. The Trust will acquire up to 7,500 cubic yards of sand from the site. The sand will be stored for future projects (subject to additional environmental review) at the “Nike site” located at Battery Caulfield. Battery Caulfield is a former Nike Ajax Missile Launch site (1954-1962) equipped with three underground missile magazines recently determined ineligible as a historic resource. The new sand will be stockpiled so as to retain required trucking circulation and to permit access for crews to sample monitoring wells at the site. The two locations proposed for stockpiling the sand will avoid the magazine doors, asphalt, existing berms, drainage, adjacent natural resource landscapes and monitoring wells. Sand hauling will involve approximately 25 truck trips per day for up to 30 days. Hauling trucks will be prohibited from entering or exiting the 14th or 15th Avenue gates.

Project Number: 14-050
Project Name: Pershing Square Fence
Planning District: Main Post
Project Type: Archaeology
CE Applied: Landscaping and landscape maintenance
CE Date: 8/14/2014
Project Description:
A post and cable fence will be installed around the southeast quadrant of Pershing Square to secure an archaeological excavation taking place. The excavation is part of the Trust’s continued efforts to reveal and understand the early construction of El Presidio. The fence posts will be placed every 8 feet in grass or the sidewalk along the site perimeter. The alignment of the fence will allow access for public use of nearby picnic tables, cultural monuments and circulation paths, accommodate landscaping and maintenance equipment, and meet fire code requirements. The fence will remain in place for the duration of the excavation, approximately 3 to 5 years.

Project Number: 14-043
Project Name: Gorgas Avenue Stairs and Crosswalk
Planning District: Letterman
Project Type: Transportation/Parking
CE Applied: Repair of roads and parking facilities
CE Date: 8/8/2014
Project Description:
A parking lot located on the south side of Gorgas Avenue across from building 1162 and adjacent to building 1076 is separated from Gorgas Avenue by a historic brick retaining wall approximately 2-1/2 feet in height. Visitors who park in the lot often jump off of the wall and cross the street to the Gorgas Warehouses without a crosswalk. This project will address the access and safety issues created by this condition and includes the construction of stairs leading from the parking lot accompanied by a new crosswalk. The stairs will be constructed at the location of the wall removed for utilities (date unknown) thereby minimizing damage to a historic resource. Two parking spaces will be removed to accommodate the new crosswalk leading from the stairs.
