Brook Narrow Drainage Advisory Committee Meeting Nov 3, 2025
Brook Narrow Drainage Advisory Committee Meeting Nov 3, 2025
The Drainage Advisory Committee convened to review the status of Proposition Six bond funds, discuss drainage crises in three specific subdivisions, and vote on recommendations for design expenditures to mitigate flooding and protect critical infrastructure. Staff presented a financial overview of the 2018 bond, noting that while all funds are allocated, closeout procedures are underway to potentially return unspent balances. The committee then reviewed and unanimously approved three distinct drainage improvement projects.
Consent Calendar
- Approved the meeting minutes of July 28, 2025 (Agenda Item 3).
- No items were removed from the consent agenda.
Public Comments & Testimony
- Leanne Lake (Resident, 1909 East Winston Street): Expressed severe frustration regarding chronic water saturation in her backyard since moving in October 2022. She testified that the builder (Shaw/Horton) failed to construct necessary drainage features, resulting in water accumulating inches from her brick porch. She noted that despite installing five drains and a pump at her own expense, her yard remains unusable for weeks after rain.
Discussion Items
- Proposition Six Bond Status (Staff Update): Patrick Wilson, Stormwater Division Manager, reported on the 2018 General Obligation Bond (voted at $5.5 million). He stated that 70 applications were received, 59 recommended to council, and 34 projects are now in closeout.
- Staff noted that $567,169.50 is allocated for Broken Arrow Creek and $105,384.12 is unallocated "Unnamed" funds available for any basin.
- Staff recommended continuing Proposition Six in the 2026 general obligation bond, with a proposed ask of roughly $5 million, alongside a $6 million Proposition 5 (stormwater) fund.
- Tucson Village 2 (Subitem A, Case 25-018): Staff presented an issue where a designed 60-foot drainage swale was omitted during construction in 2020, causing 46 CFS of flow onto private property. Videos showed severe erosion, undercutting sidewalks, and spring water bubbling up due to the high water table. Residents unanimously agreed prior to this meeting that they desired help. Staff requested $65,000 for design improvements and noted that cost-sharing arrangements with the developer (Horton) are under discussion.
- 6100 Center Commercial Subdivision (Subitem B, Case 25-020): Staff described a 40-year-old "Fabriform" concrete channel (fabric-lined concrete) that has deteriorated, causing erosion that threatens an existing 8-inch sanitary sewer line and overhead utility poles owned by 60 property owners (approximately 80 companies). The channel drains into Floral Haven Creek (a tributary to Hakey Creek). Due to the age of the project, it was not placed in a public easement. Property owners expressed strong support for the city's involvement in the design to protect their infrastructure and jobs, agreeing to dedicate drainage easements. Staff requested $5,000 for design improvements.
- East Natchez Street and Lynn Lane (Subitem C, Case 25-019): Staff discussed a severe flooding issue in a residential area adjacent to Indian Springs Country Club and Broken Arrow Creek. During a 2.2% chance (approximately 45-year) storm event in spring, overland flow overtopped a homeowner's berm and exposed a critical 60-inch (5-foot diameter) sanitary sewer trunk line feeding the wastewater treatment plant. The current system, designed under older criteria, utilized streets as conveyance during heavy events. Staff requested $75,000 for design improvements to mitigate overland flow and protect the trunk line, ensuring the system can handle a 100-year event today.
Key Outcomes
- Tucson Village 2: Approved a motion to recommend to City Council the expenditure of $65,000 for drainage design improvements (Case No. 25-018). Vote: 6-0 (Hamilton, Wallace, Pickle, Parks, Mason, Hendricks).
- 6100 Center: Approved a motion to recommend to City Council the expenditure of $5,000 for drainage design improvements to the 6100 Center Subdivision (Case No. 25-020). Vote: 6-0.
- East Natchez/Lynn Lane: Approved a motion to recommend to City Council the expenditure of $75,000 for design of drainage improvements and protection of the sanitary sewer trunk line (Case No. 25-019). Vote: 6-0.
- Adjournment: The meeting was adjourned following the roll call vote.
- Correction: Staff corrected the record stating that the crossroad culvert on 9th Street was not part of the East Natchez project, contrary to the written packet, and that only the riprap protection at that location is included.

Presentation summarizing the projects and funds spent to date of proposition six of the twenty eighteen general application bond. Good evening, Chair, Vice Chair members. I'm Patrick Wilson, Stormwater Division Manager of the Engineering and Construction Department for the City of Broken Earth. Um if you could go ahead and put up that uh PDF that is in the so what we're looking at is we're going to do a funding as to what has been allocated as a whole. So this is what the DAC has recommended to council, and then what council has approved the recommendation on now you see Adams Creek, HP Creek and Elm Creek, they've got zero funds left. That means we have allocated all the funds. All the funds have not been spent, they've been all allocated. So I'm right now in the process of doing some closeouts on some different projects, and I'm also coordinating with our finance department to make sure that my numbers and their numbers match. So I've asked finance to do an audit of what where we're at to make sure. Um just so that the committee is aware, every item that is presented tonight will fall within these net uh numbers.
