Runoff Discharges
to Nearby Waters
40% of known pollution to
nations waters is caused
by stormwater runoff
Why is stormwater runoff a concern?
Rainwater that falls on paved
streets, lawns, parking lots, and
sidewalks becomes polluted
stormwater.
Typical pollutants in stormwater
are trash, oil, fertilizers,
sediment, sand, and bacteria.

Start by developing an
inventory of all municipal
facilities What activities at the facility
have the potential to pollute
stormwater runoff?
Who is responsible for each
activity?
Put together a written
plan
Train responsible
employees on their
pollution prevention role
What can I do now?

What is GIS?
A geographic information system is a computer
system capable of assembling, storing, manipulating,
and displaying geographically referenced information
GIS data is created and
stored in thematic layers
Municipalities use and combine GIS Data
for a variety of purposes.
How does GIS work?
GIS Data combines both
spatial
and tabular information
Each spatial feature corresponds to a record in the attribute table
How do Municipalities Use GIS?
Tax Maps - Parcels
Water System
Sewer System
Stormwater
Public Works
Planning and Development
Conservation
Schools
Trails and Open Space
Disaster Planning/ Emergency Response
Planning/Zoning Stormwater System Management
How GIS supports Municipalities MS4
Requirements
Documents stormwater infrastructure
A tool for staff/contractors to find, inspect, maintain, and repair structures.
A GIS Inventory is a more reliable, efficient and organized method for Operation and Maintenance of stormwater Infrastructure.
GIS Data will be developed from a variety of sources
Base Map
Information/Photo-
grammatic
Mapping Anecdotal Information
Survey/CAD
Data
Field Data
Collection
Asset Inventory
Stormwater Inventory
2. Create GIS data from existing record plans
3. Identify data and accuracy gaps
1. Review available record plans,
documents and data sources.
This may include survey plans
from DPW Department, or
anecdotal information from staff.
4. Capture
missing
information
with field
verification
Mapping Methods
GIS Tools
There are many
programs and
applications
available to
municipalities to aid
in the collection,
viewing and
maintenance of
information.
How GIS supports Municipalities MS4
Requirements
Identifying, Labeling and Mapping Stormwater Structures and
Outfall locations.
Identifying and Mapping Impaired Waterbodies.
Identifying and Mapping Watersheds and Sub Watersheds.
Identifying and Mapping Impervious surfaces.
How GIS supports Municipalities MS4
Requirements
Mapping catchment areas (areas that contribute to outfalls).
Estimating Impervious surfaces within catchment areas.
Tracking priority outfalls
How GIS supports Municipalities MS4
Requirements
Identify and Map appropriate designated Snow
Storage Areas
Map Management Areas (Parks, Buildings,
Facilities)
Provide mapping to the public as a form of Public
Outreach and Education
How GIS supports Municipalities MS4
Requirements
Data compiled in GIS is used in conjunction with Asset
Management Systems to assist in managing inventories,
inspections, and repairs.
GIS Mapping is used for reporting purposes to document progress
and compliance.
GIS is used in the office on a desktop or in the field on a smart
phone, tablet or GPS unit to collect, document, update inventory.
GIS is used to store and inventory supporting documents like
scanned surveys, drawings, photos, and field inspection forms.
Isn't GIS Awesome?
Keep your community compliant with the
New Regulations! Use GIS!
