Strategic Plan
Strategy 1: Inspire Public Space: Keep today’s parks safe, clean and fun; promote our parks’
historic and cultural heritage; and build the great parks of tomorrow.
Objective 1.2 Strengthen the quality of existing parks & facilities
Background/Project Description
Union Square is a plaza of 2.6 acres bordered by Geary, Powell, Post and Stockton Streets in the
City of San Francisco Supervisory District Three, refer to Attachment 1 Location Map. The
Recreation and Park Department secured funding for ADA barrier removal work at Union
Square Plaza as a result of an ADA lawsuit settlement agreement (“Settlement Work”) and
disability access enhancements requested by Mayor’s Office on Disability in order to respond to
subsequent public complaints (“Enhancement Work”). The Settlement Work was completed in
2013. The scope of work for the Enhancement Work was combined with the replacement of
stairs lighting at Union Square Plaza which was a current RPD deferred maintenance project.
The Enhancement Work, depicted in Attachment 2, includes the following scope of work:
New granite edge protection at stage terrace
Additional handrail at steps adjacent to stage terrace
New removable stainless steel wheel guides at stage edges
New curbs on pathway along Geary Street
Provision of in-fill concrete stepping stones and handrails at west entry paths along Geary St.
New cane detection elements below handrails adjacent to path of travel
New improved stair lighting and conform faceplate covers
Additional handrails at stage back steps paths
New guide rails at Geary St. Garage pedestrian entry paths

The Union Square ADA Enhancement Contract was awarded by the Recreation and Park
Commission to Apadana Engineering, Inc. on February 19. 2015. Following DPW contract
certification, Notice to Proceed was issued on August 5. 2015. Per Schedule of Events and
Holiday Moratorium starting in early November 2015, contract submittals for ordering of
materials and requests for information were done before end of 2015. Construction on site

substantial completion on September 30, 2016 and final completion is anticipated in December
