Yavapai County Flood Control District Stormwater

Project Goal

Our main goal was to rapidly implement an ongoing capacity for demonstrating and reporting the performance and compliance of our Municipal Separate Storm Sewer System (MS4) program to our state regulator. We needed to overcome data silos and manual processes and wanted to centralize and standardize data.

Business Problem Solved

Under the Arizona Pollutant Discharge Elimination System (AZPDES) Stormwater permit, regulated by the AZ Department of Environmental Quality (ADEQ), the Yavapai County Flood Control District operates a Phase II small MS4.
The County MS4 is made up of 16 non-conjoined polygons with 148 outfalls along roadside curbs, gutters, ditches, channels, catch basins, culverts and storm drains that lead to several local creeks and washes. 50% of the outfalls must be inspected and photographed annually in both dry and wet conditions after rain or from snowmelt. The permit also requires the collection of water samples to track fecal E.coli levels in streams. Rather than log inspections on printed sheets in the field, then update databases back at the office, a more efficient, onsite method of datalogging was needed.

Technology Implemented

2NDNATURE Software’s cloud platform is a purpose-built stormwater compliance platform for MS4 programs, powered by Esri’s ArcGIS technology. It was game changer for the Yavapai County Flood Control District. The tablet and smartphone accessible topo map enables the stormwater engineer to modify plans in real-time during changing weather by helping track runoff. Quick data entry on the custom 2NDNATURE interface, plus the built-in photo capability has made site inspections simple and efficient. Organized recordkeeping and instant reports have made a simple task of program management.
The 2NDNATURE platform contains powerful tools that provide Yavapai County with capabilities like Best Management Practices (BMP) and Low Impact Development (LID) tools that help us plan ahead and mitigate potential flood impacts. Precipitation and soils data are integrated into the 2NDNATURE platform, so we can model runoff and infiltration of potential sBMP and LID projects, cradle to grave.
