About this opportunity
The City of Tucson is soliciting proposals for a Qualified Vendor List (QVL) for Green Stormwater Infrastructure (GSI) Landscape Maintenance, targeting specialized landscape and maintenance services for GSI assets on public property. The procurement covers seven distinct service groups: Routine GSI Landscape and Structure Maintenance, Certified Herbicide Application, Rainwater Harvesting Cistern Maintenance, Consultation/Outreach/Instruction/Data Collection, GSI Reconstruction, Manual or Truck Watering, and Irrigation System Oversight and Repair. Contractors will primarily support the City's Storm to Shade Program, administered by Tucson Water, and must follow procedures in the City Storm to Shade Program GSI Maintenance Manual and Landscape Maintenance Manual. The initial proposal period opens on March 13, 2025, with continuous submissions accepted through May 22, 2025, and subsequent reviews every three months. Contractors will be evaluated based on their experience providing specific services, ability to maintain GSI assets, and capacity to clear trash/debris, manage invasive vegetation, and ensure structural integrity and site accessibility. The contract period runs from April 10, 2025, through April 10, 2030, with work orders issued through the City's Hexagon Enterprise Asset Management System.
The solicitation does not explicitly mention specific set-aside designations or restrictions on responding organizations, though the Storm to Shade Program emphasizes creating pathways for skilled jobs in the green industry. Contractors will be required to submit pricing on a cost-per-hour basis and will be placed on a Qualified Vendor List from which the City may award contracts based on proposed service groups. While no specific incumbent vendors are listed, the program aims to maintain approximately 500 GSI assets in FY2024, with new assets being added annually. The program is funded by a consumption-based fee on Tucson Water customers, with the total maintenance program expenditure for fiscal years 2023 and 2024 reported at $723,146 and a fund balance of $9,522,576 as of June 30, 2024. Contractors must supply and maintain necessary maintenance equipment and supplies, with transportation fees calculated at the federal standard rate per mile. The City reserves the right to adjust the scope on an as-needed basis, and contractors will be required to report work using a digital application.

Update #2 · Latest ·
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. Proposals will be accepted from vendors for one or more than one group, or any combination of groups. Responses must state which groups service can be provided and with specific reference to contractor experience providing those services. The Scope of Work is based on anticipated needs and available funding. The City reserves the right to adjust the scope on an as-needed, if-needed basis.
Group 1 - Routine GSI Landscape and Structure Maintenance
Group 2 - Certified Herbicide Application
Group 3 - Rainwater Harvesting Cistern Maintenance
Group 4 - Consultation, Outreach, Instruction and/or Data Collection
Group 5 - GSI Reconstruction
Group 6 - Manual or Truck Watering
Group 7 - Irrigation System Oversight and Repair
Open and Continuous Solicitation
This solicitation will be open and continuous through April 10, 2030, meaning that the City will accept proposals from prospective offerors at any time through April 10, 2030.
