Proposed Timeline for

Implementation

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.

Within 3 Years Inspect all catch basins at least once

Screen 50% of all outfalls

Complete dry weather screening/sampling of every MS4

outfall/interconnection (except excluded and problem areas)

Complete catchment investigations of 80% of MS4 area served

by problem catchments


Within 4 Years Implement LID practices as part of land use regulations

Complete Measurement of directly connected impervious area to

all outfalls

Commence annual monitoring

Within 5 Years Complete outfall screening

Physically label all MS4 outfall pipes

Complete catchment investigations of 100% of MS4 area served

by problem catchments

Complete catchment investigations of 40% of all MS4 areas

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?

Using GIS to Facilitate

Stormwater Planning

How GIS Helps Municipalities meet

Regulatory Requirements

Connecticuts MS4 Program EBC Stormwater Seminar

March 13, 2015

Erin E. Jacque, GISP

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.


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.


Requirements

Mapping catchment areas (areas that contribute to outfalls).

Estimating Impervious surfaces within catchment areas.

Tracking priority outfalls


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


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!
