Meeting Date:09/21/2023   Requested by: John Spiker, Public Works Submitted By:John Spiker, Public Works SUBJECT: DISCUSSION AND PRESENTATION OF THE CANYON DEL ORO BIBLE CHURCH PRIVATE DRAINAGE IMPROVEMENTS  RECOMMENDATION: N/A EXECUTIVE SUMMARY: The Canyon Del Oro Bible Church located at 9200 N. Oracle Road has been experiencing drainage and sediment issues for nearly ten years from stormwater runoff emanating out of the Santa Catalina Mountains. This tributary carries significant amounts of sediment and stormwater onto the private property of the church and left uncontrolled, impacts access and movement on the property.  Initial improvements to the channel by the church were completed in early 2022, but monsoon activities during that summer left significant damage to the drainage channel, access roads and parking lot. Equipment operators were hired by the church to remove sediment in the parking lot and re-grade the channel to restore positive flow downstream.  The church reached out to the Oro Valley Stormwater Utility (OVSWU) seeking input and guidance in addressing this tributary flow. Mr. Lowell Jensen, Volunteer Coordinator and Construction Manager for the church, met with the OVSWU to discuss the roughly 50-foot wide drainage channel and associated tributaries to minimize sediment transport and scour on the church property. Lowell mentioned the limited budget available for construction, but that the church has significant volunteer work hours available.  Widening the channel, deepening the infrastructure toe down, and dropping the sediment out of the runoff water were three elements critical to a successful outcome.  Vegetation was trimmed and or removed to prevent channel blockage, rip-rap bank protection was grouted to hold in place, toe downs were extended up to three feet deep, apron pavers were replaced with concrete, and energy dissipaters in the form of boulders and flood bags were installed upstream to attempt to slow the flow of runoff and drop sediment above the entry drive. Flows from adjacent outlet structures and channels were protected from potential scour and used to guide these smaller flows into the main channel where they can be managed downstream. Building roof drains were also re-designed to control outfall and minimize scour.  In total, the Canyon Del Oro Bible Church placed 36 tons of stone rip-rap, placed 3 cubic yards of concrete, 150 cubic yards of dirt were moved, 42 flood bags were installed, and 130 boulders were placed. Lastly, roughly 300 work hours were completed by church volunteers to complete the work effort.  BACKGROUND OR DETAILED INFORMATION: N/A FISCAL IMPACT: N/A SUGGESTED MOTION: N/A N/A Attachments CDO Bible Church  Town of Oro Valley Canyon Del Oro Bible Church Private Drainage Improvements September 21, 2023 Location Sediment and Drainage Issues Initial Improvement Attempt First Monsoon Event After Initial Improvements Second Improvement Attempt Second Improvement Attempt Second Improvement Attempt Second Improvement Attempt Questions?    Stormwater Utility Commission 5.

There is a similar facility managed by Pima County called the Kino Environmental Restoration Project (KERP) which involves stormwater capture, re-use, vegetation restoration and floodplain management. This potential site visit was selected by the Oro Valley Stormwater Commissioners at the August 2023 Commission meeting. This site would allow the commissioners a view of large scale stormwater improvements and potential. Kino Environmental Restoration Project The Town has reached out to our partners at the Pima County Regional Flood Control District and they have agreed to participate in a presentation and tour of the facility with their sister agency the Kino Stadium District who manages the Kino Sports Complex where the KERP Basin resides. Pima County Kino Environmental Restoration Project The nearly 200 acre Ed Pastor Kino Environmental Restoration Project was intended to redevelop an existing storm water basin into a more environmentally sensitive and aesthetically pleasing facility to the community. The KERP facility was designed to meet three primary purposes - create native ecosystems, harvest urban storm water and control flooding. Partnering with the United States Army Corp of Engineers (ACOE) as one of the first projects constructed by the Los Angles District of the ACOE, Pima County completed the project in 2001. The final footprint of KERP facility covers nearly 200 acres with a 50-foot deep lake covering 7 acres, 20 acres of watercourses and hills. Areas have been planted with native species to create marsh habitats, mesquite bosques, grasslands and an open water environment that supports wildlife and birds. Pima County Kino Environmental Restoration Project The environmental restoration project maintains the flood storage capacity and capabilities of the original basin, while permitting water harvesting from storm flows. KERP was designed to reduce an incoming 100 year storm event peak of 15,300 cubic feet per second (cfs) to an outflow of 9,300 cfs, by detaining and storing approximately 1,880 acre feet of storm water. The project is also designed to harvest stormwater for use on vegetation within the project limits and the adjacent Kino Sports Complex athletic fields while continuing to support the basin’s original purpose of detaining stormwater.
