The Presidio Parkway is the historic south access route to the San Francisco Golden Gate Bridge and a major entryway to San Francisco.
Formerly known as Doyle Drive or Route 101, the roadway was facing the same problems that threaten other parts of our nation's infrastructure–the ravages of time and continual use. Replacing the aging Doyle Drive roadway, which was originally built in 1936, is not only critical for seismic and traffic safety but also provides an opportunity for major aesthetic design improvements.
Throughout the 10-year design and environmental review phase, ESA provided an array of services and technical studies in support of a combined environmental impact statement and environmental impact report, a Caltrans Natural Environment Study, and a sediment transport study for a storm drain in the Bay. ESA prepared permit applications and supporting documentation, including a Section 7 Biological Assessment for listed marine species and a wetland delineation and mitigation plan. Beginning in 2010, ESA monitored construction activities and documented compliance with regulatory permit and NEPA/CEQA mitigation commitments. Our staff monitored and documented permitted wetland impacts, effects of noise and construction activity on breeding birds and bird use of nearby Crissy Marsh, and surveyed for bats in trees, roadway structures, and buildings removed as part of the project.
Doyle Drive has been transformed into the envisioned Presidio Parkway, a gateway between the iconic Golden Gate Bridge and the city of San Francisco. ESA’s full suite of services was integral to attaining environmental, regulatory, and construction compliance of this regionally significant transportation project.
The Burke-Gilman Trail (BGT) is one of the most heavily used pedestrian and bicycling paths in Seattle, serving as a major transportation corridor for commuter and recreational bicyclists. Noted as a top priority project in the City’s Bicycle Master Plan, the completion of the BGT network will improve Seattle’s health and quality of life by providing safe bicycle and pedestrian travel routes for residents of all ages.
