GIS Stormwater Management
Stormwater management uses GIS to inventory drainage infrastructure, track inspections, and document compliance for municipalities, utilities, and stormwater districts. GeoLever builds stormwater asset geodatabases, ArcGIS Field Maps inspection workflows, MS4-aligned reporting, and condition dashboards. We send a written scope and flat fee within 48 hours of a 30-minute discovery call.
Most stormwater programs run on a partial pipe network, a folder of inspection PDFs, and a permit deadline. When the MS4 audit arrives, staff spend weeks reconstructing what should already be a query against an authoritative geodatabase.
We design stormwater systems around the permit and the asset at the same time. Inlets, pipes, outfalls, and best management practices live in a connected geodatabase with attribute rules, so inspections, compliance reporting, and capital planning all draw from one source.
Where Stormwater Management Projects Struggle
Most stormwater management engagements run into the same handful of problems.
Incomplete Drainage Inventory
Many programs have spatial data for some inlets and pipes but not the full network. Outfalls, best management practices, and private connections are often missing, which undermines both modeling and compliance.
MS4 Permit Reporting Burden
Municipal separate storm sewer system permits require documented inspections, outfall screening, and BMP tracking. Assembling that documentation from disconnected records consumes weeks each cycle.
Disconnected Inspection Records
Inspections, illicit discharge investigations, and maintenance live in PDFs and spreadsheets that are not tied to the spatial asset, so trends and overdue work stay invisible.
Connectivity and Flow Uncertainty
Without validated connectivity between inlets, pipes, and outfalls, tracing flow paths and source-tracking illicit discharges relies on field guesswork instead of the geodatabase.
BMP Performance Tracking
Green infrastructure and structural best management practices require ongoing inspection and performance tracking that spreadsheets cannot tie to location, drainage area, or maintenance history.
GeoLever's Approach to Stormwater Management
We design every stormwater management project around the decision it needs to support.
Stormwater Asset Geodatabase
Design a stormwater geodatabase covering inlets, pipes, outfalls, channels, and best management practices with attribute domains, attribute rules, and validated connectivity for flow tracing.
Field Maps Inspection Workflows
Configure ArcGIS Field Maps and Survey123 for routine inspections, outfall screening, and illicit discharge investigations with validation rules, photos, and offline support.
MS4 Compliance Reporting
Build geodatabase schemas and dashboards that produce MS4-aligned documentation for inspections, outfall screening, and BMP tracking with minimal manual assembly each permit cycle.
Connectivity and Flow Tracing
Validate inlet, pipe, and outfall connectivity so the network supports upstream and downstream tracing for illicit discharge source identification and drainage analysis.
BMP Performance Dashboards
Create dashboards that tie green and structural best management practices to drainage areas, inspection history, and performance so maintenance and capital decisions rest on spatial data.
Stormwater Management Deliverables
Decision-ready outputs designed for the people who will actually use them.
Stormwater Network Geodatabase
A connected stormwater geodatabase with inlets, pipes, outfalls, channels, and BMPs, attribute rules, and validated connectivity that supports inspection, compliance, and flow tracing from one source.
Inspection Field App Configuration
Configured ArcGIS Field Maps and Survey123 workflows for inspections, outfall screening, and illicit discharge investigations with validation, photos, and offline support.
MS4 Compliance Dashboard
An ArcGIS Dashboard that surfaces inspection status, overdue work, outfall screening progress, and BMP performance for staff and produces permit-cycle documentation.
GeoConsult engagement
How we scope stormwater management
Project-based pricing under GeoConsult. Cost scales with network size, the completeness of existing inventory data, and the depth of MS4 compliance and BMP tracking required. Ongoing program support runs project-based pricing per month under GeoPartner.
Stormwater Management: FAQ
Can you build a stormwater inventory from incomplete data?
Yes. We consolidate existing inlet, pipe, and outfall data, identify gaps, and design field collection workflows to complete the network. We do not stand in as the certified engineering firm of record.
Do you support MS4 permit reporting?
Yes. We design geodatabase schemas and dashboards that document inspections, outfall screening, and BMP tracking aligned to MS4 permit requirements, reducing manual assembly each cycle.
Can field crews collect inspections without ArcGIS Pro?
Yes. Crews use ArcGIS Field Maps and Survey123 on phones and tablets, including offline. Inspections, photos, and discharge investigations sync directly into the geodatabase.
Do you build hydrologic or hydraulic models?
No. We build the authoritative asset geodatabase, connectivity, and reporting. Hydrologic and hydraulic modeling is produced by engineering consultants; we structure data to support it.
How much does GIS stormwater management cost?
GeoConsult project pricing scales with network size, existing data completeness, and compliance scope. Ongoing program support runs project-based pricing per month under GeoPartner.
Can you support illicit discharge source tracking?
Yes. We validate network connectivity so the geodatabase supports upstream and downstream flow tracing for illicit discharge investigations and source identification.
