Qualified Vendor List (QVL) for Green Stormwater Infrastructure (GSI) Landscape Maintenance

The City of Tucson herein referred to as “City,” requests proposals from qualified firms for specialized landscape and other maintenance services for Green Stormwater Infrastructure (GSI) assets located on public property in Tucson. GSI assets are comprised of inlets and outlets/overflows, earthworks (such as basins, berms, and swales) that contain and direct the flow of water, as well as the vegetation within and adjacent to these features.  Maintenance of GSI assets ensures the physical structures and landscaped features designed to capture and use stormwater runoff from hardscape are clear of trash/debris, invasive vegetation, and sediment; and that the rockwork is structurally sound and trees are not blocking pedestrian or vehicle site visibility or access.  GSI maintenance requires a holistic and careful approach to ensure the City’s investments in these assets are maintained in a manner that reflects their value as a public resource and part of the City’s infrastructure. Contractors will primarily perform services for the City of Tucson’s GSI Storm to Shade Program (https://tucsonaz.gov/gsi), which is administered by Tucson Water and will follow procedures outlined in the City Storm to Shade Program GSI Maintenance Manual version 1 (2022), pending publication of v.2 (2025) and the City Landscape Maintenance Manual (2021).The City may award by group or by combination of groups that provide the following services.
