ZARZAMORA CREEK GREENWAY TRAIL San Antonio, Texas
PROJECT DESCRIPTION
The City of San Antonio (City) is requesting $25 million for
engineering, right-of-way and construction funds to
complete the Zarzamora Creek Greenway Trail (ZCGT), a
7.1-mile segment of the 82 mile Howard W. Peak
Greenway Trails System which is an accessible, multi- use
trail network adjacent to the VIA Metropolitan Transit
Ingram Transit Center, City, Bexar County (County), and
San Antonio River Authority (SARA) waterways, to
improve: multi-modal access to employment centers;
quality of life; safety; and health of several low-income
communities of color. Completion of the Zarzamora
Creek Greenway Trail will add connections to over 50
trailheads, employment centers, cultural landmarks and
recreational facilities throughout the City of San Antonio.
Howard W. Peak Greenway Trails
In the 1990’s, San Antonio Mayor Howard W. Peak, had an
idea to build a ring of trails around the City along the
Salado, Leon and Westside Creeks (Alazan, Apache,
Martinez, San Pedro and Zarzamora) and Medina River.
What began as a network of recreational trails in 2000 –
upon completion – will be 130+ miles of multi-use trails
accessible to San Antonio’s rich cultural history and iconic
landmarks, interspersed between major, regional
employment and educational centers including, but not
limited to:
• The Riverwalk
• The Alamo
• Fort Sam Houston/Lackland Air Force Base
• San Antonio Missions National Park & Mission Reach
Trail Segment
• AT&T Center
• The University of Texas at San Antonio
• Historic West Side
• Six Flags Fiesta Texas
As of 2021, over 82 miles of trails have been completed;
15 miles are under construction and another 17 miles
are in some stage of planning or design across the City
and County. Completion of this dynamic and diverse trail

infrastructure initiatives to make San Antonio a
more EV-friendly city. The Howard W. Peak Greenway Trails System is
located almost entirely within floodplains of the
waterways which they follow. To protect water
quality, mitigate the effects of flooding, and improve
ecosystem function, it is important to incorporate
“Green Infrastructure” elements in future trail design
and improvements. Low Impact Development (LID)
refers to landscape elements which use natural
systems for water infiltration, detention, and
retention to minimize negative impacts of
development near water bodies. These methods can
be adapted to a wide variety of contexts and
climates; however the central principles remain
consistent.10
The design of a sustainable trail that connects to
public transportation supports the goals and
objectives of the City to reduce air pollution. The LID
design of the proposed Zarzamora Creek Trail trail
would meet or exceed local, state, and Federal water
quality requirements and enhance and restore the
floodplain ecosystem.
