Project Description
Project Number18-042
Project NameQuartermaster Reach Olympia Oysters Restoration
Planning DistrictCrissy Field
Project TypeMiscellaneous
CE AppliedResearch, monitoring, inventorying, and information gathering
CE Date7/16/2018
Project Description
The native Olympia oysters (Ostrea lurida) nearly disappeared from San Francisco Bay following overharvest during the Gold Rush (1848-50s) and massive silting from hydraulic mining in the Sierra Nevada (1850s-1880s). But in the 1990s, O. lurida once again appeared in San Francisco Bay near the Chevron Richmond Refinery in Richmond, California. As part of the upcoming Quartermaster Reach (QMR) restoration and with input from National Park Service and California Department of Fish and Wildlife resource specialists, this project will introduce substrate into the intertidal zone to support natural recruitment of this species of oysters. Oysters are an important species for restoration because they improve water quality and create habitat for aquatic vegetation and animals. Two forms of substrate will be introduced after QMR is excavated and constructed: polyethylene mesh bags of oyster shell, and form-cast reef balls made from a mixture of cement, sand, and oyster shells. The substrate will be derived from over ten cubic yards of treated (i.e., dried, bleached and steamed to prevent unwanted pathogens) oyster shells that have been collected from five San Francisco restaurants and are currently being stockpiled at Fort Scott. In addition, fabricated concrete panels installed within the culverts and fiberglass panels placed on the marsh bottom may also be used to attract oyster larvae.

Project Number18-043
Project NameInspiration Point East Endangered Species Habitat Expansion
Planning DistrictSouth Hills
Project TypeVegetation Restoration
CE AppliedRemoval of non-threatened or endangered species
CE Date7/13/2018
Project Description
Since 2001, the Trust has followed the Vegetation Management Plan (VMP) to expand endangered plant species populations, increase genetic diversity and recover the species, including enhancing and restoring habitat throughout the Inspiration Point area. The current 0.5-acre project site is at the south edge of Inspiration Point near the Ecology Trail within the VMP Native Plant Community Zone known as the East Grassland. The project site is dominated by blackwood acacia, English ivy and Armenian blackberry and is underlain by serpentine soils at its northern end and by landslide deposits toward the south. The project will remove approximately 50 blackwood acacia and 3 Monterey cypress trees. English ivy, Armenian blackberry and cotoneaster will be cleared and grubbed. Stumps from acacia trees will be ground up to 10 inches below soil surface. Following tree removal, exotic invasive annual grasses and perennial shrubs will be controlled after initial germination by a combination of tarping, herbicide, hand removal and possibly soil steaming. Following weed control, approximately 2,000 native plants consisting of about 40 coastal scrub species will be planted including the endangered Franciscan manzanita and Presidio clarkia. The goal is to create a mosaic of coastal scrub/oak/woodland and serpentine grassland after a three-year establishment period.
 
Project Number18-046
Project NameElectric Vehicle Charger Stations
Planning DistrictPresidio-wide
Project TypeTransportation/Parking
CE AppliedReplacement of minor structures and facilities
CE Date7/10/2018
Project Description
The Trust owns and operates eight public electric vehicle (EV) charger stations. The EV charger stations are intended to encourage Presidio tenants to purchase battery electric cars, which produce fewer emissions than gas vehicles. Three of the charging stations are broken and the five remaining stations do not meet the current demand for EV chargers in the park (based on usage data). To meet the current need, the Trust will replace some of the charger stations (behind building 102, at building 558, and in the Tides parking lot) with newer dual port stations. The work will be completed by a licensed contractor in coordination with the High Voltage and Permitting departments. No digging or additional signage is required.
 
Project Number18-047
Project NameDenitrification Trenches above the North Arm of Mountain Lake
Planning DistrictSouth Hills
Project TypeInfrastructure
CE AppliedInstallation of underground utilities
CE Date7/10/2018
Project Description
Increased nitrogen creates problems with maintaining water quality (such as algae blooms) in Mountain Lake. This project will reduce the amount of nitrogen in the water coming off of the Presidio Golf Course and flowing into the lake. The high nitrogen levels are the result of years of over-fertilization of the golf course during the U.S. Army era. Two trenches, each 5 feet deep and 5 feet wide running a total of 230 lineal feet, will be dug in the vicinity of the former non-historic building 350 (demolished circa 2008). Any excess soil will be placed in a low area below a steep cut in the northern portion of the site. A mass of wood chips will be laid in the trenches wrapped in a filter fabric and then covered with drain rock. Water will be collected in the woodchips, which house bacteria that utilizes the nitrogen in the breaking down of the wood.
 
Project Number18-044
Project NameBuilding 67 Work Stations
Planning DistrictMain Post
Project TypeRehabilitation/TI
CE AppliedRehabilitation or improvement of historic properties
CE Date6/29/2018
Project Description
In order to accommodate seven new work stations on the first floor of the historic portion of building 67 (Telephone Exchange, built 1919 with 1960s additions), this project will pull data and electrical power from the basement level through the concrete floor to a new junction box located on a structural column. Data and power will then be run through furniture to create six workstations. In the adjacent suite 100A, data and electrical power will be extended through wire mold to one new workstation inside the suite. New carpeting will be installed throughout the first floor.
 
Project Number18-041
Project NameCrissy Field Avenue Closure
Planning DistrictCrissy Field
Project TypeTransportation/Parking
CE AppliedSpecial events, public assemblies, and meetings
CE Date6/25/2018
Project Description
The 0.15-mile Crissy Field Avenue will be closed to all vehicles but emergency response vehicles to discourage cut-through traffic between the Marina Gate and the Golden Gate Bridge, and to improve pedestrian and bicycle access between two popular visitor destinations, Crissy Field and the Golden Gate Bridge. Motorists will be diverted to southbound McDowell Avenue to westbound Lincoln Boulevard, adding approximately 0.5 miles to their trip, or will shift to U.S. Highway 101. Uphill cyclists will be permitted and downhill, or eastbound, cyclists will be prohibited until a safe design is implemented. Visitors will be alerted of the closure through regulatory signage and flexible delineators. The closure is one of various pilot measures by the National Park Service, Golden Gate Bridge Highway and Transportation District and Trust to relieve traffic congestion near the bridge and is envisioned in the Presidio Trails and Bikeways Master Plan.
 
Project Number18-032
Project NameThomas Avenue Reforestation Phase II
Planning DistrictSouth Hills
Project TypeTrees
CE AppliedRemoval of non-threatened or endangered species
CE Date6/19/2018
Project Description
Tree failures during the winter of 2016/2017 have prompted the Trust to institute a tree replacement project in the Infantry Terrace neighborhood. This phase of the project will remove 30-40 overstory Monterey cypress in poor health (as expressed in poor crown densities, structure and form) in a 0.7-acre area proximate to the high voltage line and garages from 379 Infantry Terrace to 380 Infantry Terrace. Removal will include understory shrubs and trees such as Blackwood acacia and Star acacia. Coast redwoods will not be removed. Trees to be replanted will include mostly low stature, native trees and shrubs near the infrastructure and Monterey cypress and Coast redwood farther to the west and up the hill away from the garages, power lines, road and residences. A total of 150 trees will be planted. Where feasible, well-cured Trust compost will be applied on slopes and behind garages followed by the installation of drip irrigation. Steep slopes will require erosion control, including wattle bundles and sterile straw. No stumps will be ground as leaving stumps will temporarily increase slope stability until replacement vegetation is established. Trees will be irrigated for four years and then thinned to a density of 30 to 50 trees.
 
Project Number18-033
Project NamePark Stand Reforestation Phase III
Planning DistrictSouth Hills
Project TypeTrees
CE AppliedRemoval of non-threatened or endangered species
CE Date6/19/2018
Project Description
The Monterey cypress stand occurring within the broad loop of Park Boulevard west of the National Cemetery is one of the historic forest stands in the Presidio. The Park Stand has unusual visual quality and provides an important visual barrier to the National Cemetery. Trees in the stand are characterized with a very low percentage of live crowns, limiting the vigor of the old trees, and have now reached a state of over maturity. This phase of the project will remove and restore approximately 50 rapidly declining Monterey cypress trees just north of Park Stand Reforestation II (project 17-023). Stumps will be ground, and 300 yards of Trust compost will be applied prior to installing a drip irrigation system. Approximately 125 Monterey cypress trees will be planted. Trees will be established over a four-year period with subsequent thinning to arrive at 30 to 50 trees per acre. As with the other phases, removal of the existing trees and the replanting and early management of the replacement stand will follow Dr. Joe McBride’s recommendations.
 
Project Number18-034
Project NameWest Pacific Reforestation Phase X
Planning DistrictSouth Hills
Project TypeTrees
CE AppliedRemoval of non-threatened or endangered species
CE Date6/19/2018
Project Description
The Monterey cypress forest stand along West Pacific Avenue was regularly topped by the U.S. Army in order to manage the height of the trees to maximize the view of the bay and the Golden Gate Bridge for the surrounding neighborhood. This management regime, along with the introduction of Armillaria root rot has led to the rapid decline in health that is currently evident within the historic forest stand. This project will remove and restore approximately 50 topped, diseased and declining Monterey cypress in a 2.75-acre area directly east of the Julius Kahn Playground. Rehabilitation of the stand will include planting roughly 200 lower growing McNab cypress and Sargents cypress (to negate the need for future topping) as the future overstory for the stand, along with toyon, manzanita, coyote bush, ceanothus and other suitable species in the understory. All roots and below ground material will be removed and hauled offsite. Roughly 500 yards of Trust compost will be tilled into the soil before the drip irrigation system will be installed. Twelve inches of wood chips from the above ground material will be applied over the amended soil before planting.
