Project Description
Project Number: 15-016
Project Name: Building 105 Pre-Design Investigations
Planning District: Main Post
Project Type: Research/Testing
CE Applied: Research, monitoring, inventorying, and information gathering
CE Date: 2/18/2015
Project Description:
Investigative tests are needed to gather information at Montgomery Street Barracks, building 105 (two-company barracks, 1897) to help inform structural, site and architectural designs for a future rehabilitation project. A number of pre-design investigations will be performed both in and around the building footprint that will include geotechnical investigations, 36 interior masonry push tests, 3 basement test-pits, interior hazardous materials testing, a site survey and topographic mapping. Locations have been carefully identified to minimize removal or alterations to historic fabric. All testing will be performed with Trust oversight.

Project Number: 15-002
Project Name: MacArthur Meadow Wetland Restoration
Planning District: East Housing
Project Type: Vegetation Restoration
CE Applied: Removal of non-historic materials and structures
CE Date: 2/17/2015
Project Description:
MacArthur Meadow is located within the Tennessee Hollow Watershed where the three creek tributaries in the watershed converge, forming a single channel at the historic Lovers’ Lane bridge site before flowing north to the restored Thompson’s Reach and Crissy Field Marsh. Historically, the site was a gently sloped marshland before the U.S. Army installed drainage channels and fill. Today, the site is a shallow, concave, oval-shaped dry meadow with a few wetland areas. Vegetation within the site is dominated by non-natives and limited areas of existing freshwater wetland and rock-lined channel. This project will restore an ecologically functional, freshwater wet meadow and riparian habitat unique to the Presidio and San Francisco. Non-native vegetation will be cleared to allow for replanting with a diverse array of native wetland and upland plant species. Approximately 23,000 individual plants comprising a diverse mixture of roughly 60 different native species will be used. The site will be graded to achieve desired hydrologic connectivity and topography requiring the removal of approximately 10,000 cubic yards of soil/fill materials. Opportunities to beneficially reuse materials in other nearby locations will be considered wherever feasible. Final grading will create a network of 1,500 feet of new earthen creek channels, 3.82 acres of new wetland, and 0.12 acres of upland for a total of 3.94 acres. The existing at-grade trail (Lovers’ Lane) bisecting the site will be replaced with an elevated boardwalk designed to resemble the boardwalk that was historically in this location. Site restoration will take into account data collection related to soil and groundwater conditions, a conceptual model, and watershed-wide ground-surface water model. The project will retain and/or incorporate contributing landscape and drainage features into the restoration plan, and will follow a site-specific archaeological management assessment (AMA) and cultural landscape treatment recommendations (Main Post CLR) in order to avoid adverse effects to historic resources.

Project Number: 15-015
Project Name: Cavalry Stables Parking Lots Construction
Planning District: Crissy Field
Project Type: Transportation/Parking
CE Applied: Rehabilitation or improvement of historic properties
CE Date: 2/17/2015
Project Description:
Currently there are 153 parking spaces in the parking area immediately surrounding the Hangar Complex buildings at the western end of Crissy Field (Area B), and 93 spaces in the lot surrounding historic buildings 667 and 668 (Cavalry Stables, built 1914). These spaces are insufficient to serve the recreational and visitor-oriented uses called for in the PTMP. This project will construct an additional 170 spaces in a series of lots on the east and west sides of McDowell Avenue, north of the historic stables, in order to support the demand generated by the buildings in the two areas. The site will be graded and sub base and/or base material for the parking lots will be installed potentially using material imported to the site for the Presidio Parkway staging areas. Other elements of the work include curbs, parking lot paving, lighting, planting, bio-swales, irrigation and construction of pathways connecting to nearby buildings and roadways. Drive aisles of the parking lot will be standard asphalt paving and the parking stalls will be pervious concrete. Stormwater treatment will be coordinated with the planned stormwater project to control flow to outfalls I-J-K-L. Lighting will minimize up-light and trespass, and will go dark or be reduced to a minimum level afterhours. Restrictions set forth in land use controls established for the area will remain in effect. The parking lot design will follow treatment recommendations in the 2005 Cavalry Stables Cultural Landscape Report, and be coordinated with the surrounding landscape design for the Presidio Parkway project.

Project Number: 15-014
Project Name: Fort Scott Officers' Club Landscape Enhancements
Planning District: Fort Scott
Project Type: Landscaping/Site Work
CE Applied: Landscaping and landscape maintenance
CE Date: 2/9/2015
Project Description:
In the fall of 2010, the landscape architectural firm RHAA completed a landscape study for the grounds surrounding the Fort Scott Officers Club (building 1331, constructed 1921), which expanded on the treatment recommendations in the 2008 Fort Scott Cultural Landscape Assessment (CLA). The study included an existing plant inventory and concept studies for landscape treatments surrounding the building and adjacent tennis courts. Recently the site has been identified as a possible location for focused volunteer landscape maintenance and enhancement. The RHAA study and CLA will serve as guides for the effort, as well as ongoing maintenance and limited planting. As the initial work will be undertaken by volunteers (and later, possibly under landscape contract), it is expected to proceed gradually. The work will center on the beds east of the tennis courts, referred to as the Palm Garden in the RHAA study in recognition of the several types of palms located there. A small number of ornamental plants known to be aggressive invaders at this location will be cleared and replaced by palms, consistent with the landscape’s highly ornamental historic character. Trust landscape crews and the Historic Landscape Architect will direct the volunteers to avoid adverse effects to this important but degraded site.

Project Number: 15-011
Project Name: East Mason Electric Undergrounding
Planning District: Crissy Field
Project Type: Infrastructure
CE Applied: Installation of underground utilities
CE Date: 1/13/2015
Project Description:
This project will relocate existing overhead electric distribution facilities into new and existing underground pathways in Mason Street. The project facilitates future rehabilitation of the Mason Street warehouses (buildings 1182 through 1188), and supports the Trust’s policy to remove overhead electric service where feasible and beneficial. The new underground alignment consists of two 4-inch conduits from the existing electric vault in Mason Street just west of building 1185 to a new electric vault at the west end of building 1188. The alignment will be constructed by typical open cut excavation methods. Traffic controls may reduce traffic to a single lane around the work zone with flaggers directing one-way traffic. Excavated soil will be reused as backfill with any excess or non-reusable soil disposed offsite. The project is largely outside of archaeologically sensitive areas, forested or natural areas, remediation zones and trails. The railway alignment, a historic feature in the project vicinity, will be avoided.

Project Number: 15-012
Project Name: Building 38 3rd Floor Tenant Improvement
Planning District: Main Post
Project Type: Rehabilitation/TI
CE Applied: Rehabilitation or improvement of historic properties
CE Date: 1/13/2015
Project Description:
This project will provide new office space for a subtenant on the third floor (attic) of historic building 38 (Barracks/Sixth Army Headquarters, built 1940). The work includes construction of new interior partitions, doors; and installation of new lighting fixtures, carpet and painting. The project will not alter or damage existing historic finishes including original perimeter walls, windows, bull nosed window sills, concrete posts, and tile detailing found at the base of some walls and posts.

Project Number: 15-013
Project Name: Building 39 Café Renovation
Planning District: Main Post
Project Type: Rehabilitation/TI
CE Applied: Rehabilitation or improvement of historic properties
CE Date: 1/13/2015
Project Description:
This project will renovate the café in the building for the same purpose. The scope of work includes removing the freestanding wood benches (furniture) and adding chairs in their place, reupholstering the existing banquette, replacing the existing counter with a new smaller movable counter, and adding new paint. No additional mechanical, electrical or plumbing are proposed and no impact on historic fabric is expected.

Project Number: 15-009
Project Name: Goat Grazing at Central Magazine, Building 1469 and Battery Dynamite
Planning District: South Hills
Project Type: Landscaping/Site Work
CE Applied: Landscaping and landscape maintenance
CE Date: 1/9/2015
Project Description:
For the past few years, goats currently impounded on the golf course have been used as an alternative method of vegetation management (12-031) . The goat herd will be brought to Central Magazine (buildings 1470 and 1471), the nearby historic reservoir (building 1469) and Battery Dynamite to clear areas completely overgrown with a variety of plants including non-native blackberry, English ivy, and poison oak. Goat grazing is expected to reveal hidden hazards (such as vaults) so that they can be mitigated and to possibly adjust existing fences to allow for greater public access in the future. At Central Magazine and building 1469, only minimal additional non-electrified fencing will be necessary to control the goats. At Battery Dynamite, a long run of new control fencing will be required to prevent the goats from leaving the battery and entering the compost area of the Fort Scott corporate yard. Bird nesting surveys will be conducted as warranted.

Project Number: 15-010
Project Name: Presidio Golf Course Driving Range Netting Modifications
Planning District: South Hills
Project Type: Golf Course
CE Applied: Replacement of minor structures and facilities
CE Date: 1/9/2015
Project Description:
This project will modify the Presidio Golf Course’s existing driving range netting (08-049) in response to a player injury that occurred late last year along the 1st fairway. The current height and position of the netting will be supplemented to reduce risk to public safety in the future. Three existing poles adjacent to the 1st hole will be extended by 15 feet and four 65-foot tall poles and 200 linear feet of netting will be added to the back of the driving range. This will lengthen the range from its current location by approximately 20 yards. One large cypress tree (#265) will be removed and several other trees will be pruned to facilitate location of new netting. Current poles and netting will be left in place in anticipation of the current tree line providing ultimate protection once they reach maturity.

Project Number: 15-008
Project Name: Mountain Lake Aeration Facility
Planning District: South Hills
Project Type: Vegetation Restoration
CE Applied: Removal of non-threatened or endangered species
CE Date: 12/30/2014
Project Description:
The construction of an aeration facility for Mountain Lake was proposed as part of the Mountain Lake Enhancement Project and evaluated in the Mountain Lake Environmental Assessment. The facility is needed in order to remove algal blooms that will continue to grow until plant life has been well established and can aerate the lake naturally. This project is for the installation of a concrete pad, air compressor, and underground electrical conduit for the facility on city property near the corner of Funston Avenue and Lake Street. The air compressor will be mounted on top of the concrete pad in a self-contained cabinet. The cabinet will be located behind storage containers without designated trails or access. The Trust obtained a CEQA exemption for the project from the city’s Planning Department.
