Oro Valley stormwater commission reviews completed projects and seeks federal support for larger repairs

ORO VALLEY, Ariz. ' At its March 19, 2026 meeting the Oro Valley Stormwater Utility Commission reviewed recent stormwater improvements and discussed funding prospects for larger repairs and forthcoming projects.

Stormwater Division Manager Dennis Roberts summarized maintenance work, completed capital improvements and coordination with federal and regional partners. "These projects will strengthen system performance, reduce localized flooding and address erosion and infrastructure vulnerability," Roberts said, adding that most ongoing work remains within the division's adopted operating and capital budgets.

Roberts highlighted several completed projects with before-and-after photos and funding details. He said Sierra Wash at Naraha Drive was completed March 2, 2026, with $211,000 in federal funding and an $83,000 town contribution. Work at the same wash and nearby sites finished in May 2023 with federal support and a town match (Roberts gave a $309,000 federal contribution and a $103,000 town contribution, for a $412,000 total). The town and Pima County partnered on a reconstruction at Oro Valley Drive adjacent to a golf course; Pima County funded the project at approximately $180,000, below an initial $300,000 budget estimate, Roberts said.

Commissioners asked about debris-capture installations and regional coordination; Roberts said he would investigate whether trash-trap devices recently added on the Santa Cruz River are suitable for local washes. He also described routine maintenance efforts (channel clearing, vegetation management, sediment removal and culvert cleaning) and said staff are participating in regional advisory committees.

The commission reviewed current and planned projects, many contingent on outside funding. Roberts described projects at Rooney Wash (estimated $65,000); Nani Wash at Paseo Del Norte (safety and structural concerns; est. $85,000); and a Catalina Ridge Channel sediment removal option (est. $388,000). He said the Sierra Wash at Glover project has permit approval and is awaiting FEMA funding (federal share cited as $234,000, town contribution $78,000; estimated total $312,000). For a pomegranate-drive area (listed as the "gravel pit"), Roberts said FEMA had offered roughly $209,000 and the town's share would be about $70,000 (total ~ $280,000); he cautioned that replacing the spillway with a full culvert could increase costs substantially (preliminary estimate about $1.2 million) because of upstream sheet flow requiring diversion and downstream grading.

Roberts said Highland Wash (near a mobile home park) remains in HMGP environmental and historical-preservation review and that a final cost is still being developed. Mudders Wash and Carmack Wash were described as larger, complex projects requiring detailed survey and design work; cost estimates remain under development.

Several projects Roberts discussed are tied to federal grants and subject to outside timelines. He told commissioners that FEMA and DHS had slowed some reviews, that permit applications for some projects are approved, and that he checks for funding updates monthly.

Roberts also previewed the commission's annual field trip scheduled for April 16, with proposed stops that include North Paseo Del Norte, the Catalina Ridge access point, Sierra Wash sites, the Pomegranate Drive gravel pit and Carmack Wash; commissioners asked to add Highland Wash and to include at least one project that demonstrates a highly successful completed effort.

Procedural items: commissioners approved the Feb. 19, 2026 meeting minutes by voice vote and adjourned at 5:01 p.m.

What's next: staff will follow up on the trash-capture question, continue coordination with FEMA/DEMA for pending grants and circulate the finalized April 16 field-trip itinerary to commissioners.
