The Presidio Trust is now preparing the Quartermaster Reach Environmental Assessment (EA) to evaluate the environmental effects of “daylighting” an approximately 850-foot length of stream currently running through a subsurface culvert that ultimately discharges to Crissy Marsh in order to restore and create wetland habitat. View the Quartermaster Reach Project Overview.

The Quartermaster Reach EA will be available for public review in late spring 2010.

Where is Quartermaster Reach? (View Map)

The project site encompasses approximately 9.5 acres along the western edge of the Letterman District in the northeastern portion of the Presidio. It is bounded by Halleck Street to the west, Crissy Marsh to the north, Thompson Reach to the south, and a series of buildings and parking lots to the east. The site is within the Doyle Drive construction corridor and is at the northern-most (lowest) end of the 271-acre Tennessee Hollow watershed. The project site is referred to as Quartermaster Reach in recognition of past U.S. Army activities in the area. (View map)

What is the Project and Why Now?

The project would provide a riparian corridor and pedestrian trail through Quartermaster Reach that would connect a recently restored 450-foot stretch of stream and native habitat to the south (known as Thompson Reach) to Crissy Marsh, and reveal and/or interpret missing historic elements in the site. The project is being considered at this time to take advantage of the opportunity to be completed consistent/concurrent with design and construction of the Doyle Drive project. Excavation within the project site will be completed as part of Doyle Drive construction. Therefore, coordination between the two projects is essential to ensure the feasibility of Quartermaster Reach restoration to the maximum extent possible with the future roadway.

What are the Project Objectives and Alternatives?

The project objectives include:

• Daylight the stream and provide a hydraulic connection between Thompson Reach and Crissy Marsh.
• Create a continuous wildlife corridor from Thompson Reach to Crissy Marsh.
• Provide a succession of biologically rich and diverse wetland habitat types, with species and structural diversity, that require minimal long-term intervention.
• Re-establish natural processes to the restored stream to the extent possible.
• Enhance public use, access, and experience of the project site while maintaining visitor safety and protecting natural resources.

Three alternatives to achieve these objectives are being studied in the EA (view Alternatives Maps):

• Stream Alternative (no action)
• Marsh Alternative (preferred alternative)
• Lagoon Alternative
