Doyle Drive HALS Documentation

Location: San Francisco

Project Type:

For PGAdesign, the scope of the Doyle Drive Project—undertaken to remove the seismically unsafe Golden Gate Bridge approach and restore the landscape—was to prepare measured drawings for the cultural landscape associated with Doyle Drive within the Presidio in San Francisco. Our complex site was over a mile long and interfaced with an overhead roadway, at grade roadways, and a network of landscape trails and spaces.

PGAdesign pioneered in producing measured drawings that complied with the requirements of the very new Historic American Landscape Survey (HALS). When we began our work no similar documentation existed for such a unique site and there was no clear methodology to follow. We developed techniques for each component and graphic technique that was needed to accomplish the work. We then tested those techniques and refined our approach. The objective was to present the information in a manner that would be easily understood and legible. The measured drawing set included plans produced in AutoCAD, sections, view diagrams, a figure-ground plan, hand-drawn details, a period plan and typology sheets that depict features within the historic landscape.

Our work to preserve the landscape history has helped shape present day design plans. New pedestrian trails from Crissy Field to the bridge feature interpretive exhibits highlighting the battery views which are derived from the HALS documentation.
