Remaining Overflows
FY17-20 Planned Overflow Removal
FY13-16 Overflow Removal
FY92-12 Overflow Removal
The initiative to improve water quality and alleviate
many wastewater concerns in the St. Louis region
Long-term effort by the Metropolitan St. Louis Sewer
District (MSD), undertaken as part of an agreement
with the U.S. Environmental Protection Agency and
the Missouri Coalition for the Environment
Will invest billions of dollars over a generation in
planning, designing, and building community
rainscaping, system improvements, and an
ambitious program of maintenance and repair

STORMWATER NEXT STEPS

Proposition S: April 2016
Voters passed Proposition S in April 2016
The issue addressed by Proposition S was unequal
storm sewer operations and maintenance funding
across our service area
Proposition S simplified and equalized these services
with regard to operations and maintenance in the
public storm sewer system
Now, MSD is exploring options to fund District-wide
capital projects addressing erosion and flooding
10
Proposition S Results:
1.Stormwater management throughout the service area:
•Enforcement of rules and regulations for stormwater improvements that
can be made in our community;
•Stormwater complaint investigation and logging;
•Evaluation of all stormwater issues within MSD's boundaries; and
•Water quality sampling and monitoring of area creeks and rivers.
2.Compliance with our area's Phase II Stormwater Permit with
the State of Missouri. MSD is a co-permittee with 59 local
municipalities and St. Louis County, and performs area-wide
services as part of that permit:
•Regular inspection of area creeks for illegal discharges;
•Public education on Phase II requirements; and
•Coordination of all permit-related activities performed by local
municipalities and St. Louis County.
3.Ownership and maintenance of constructed stormwater
infrastructure, which includes stormwater sewers, inlets,
manholes, and concrete channels.
•Now equalized across the service area with the passage of Proposition S
in April 2016. 11

District Funding:
$0.0197 regulatory tax
+ $0.10 stormwater tax
= $0.1197 total tax rate
•Includes regulatory
compliance
•Includes complete
operations and
maintenance
•Includes limited funding
for necessary capital
improvements:
•FY17-20: ~$67M

Unfunded Stormwater Issues
MSD customers have told us they have been
impacted by erosion, localized flooding, and
regional flooding in our area
MSD is not a flood control agency and does not
own creeks or streams, but we do have the power
to address the results of past development
MSD cannot prevent localized flooding and erosion
– but could provide projects that would lessen the
possibility of future localized flooding and erosion
MSD is currently unable to address regional flooding
– but could if MSD had funding for large-scale
property buyouts
Today, as rainfall becomes more intense, we can
no longer try to engineer around Mother Nature

~500 stormwater issues
identified, but unfunded
Total cost: ~$500M

Rainscaping Stormwater Drainage Systems
Should MSD provide full regional
stormwater services?
Key Issues:
Localized Flooding
–Backyard or localized
flooding that may affect
a few contiguous
properties
Erosion
–Erosion of creek or
stream banks along
private property lines
Regional Flooding
–Large-scale flooding of
waterways impacting
streets, properties, and
structures
Potential Solutions:
19
Localized Flooding
–Stormwater drainage
systems
–Property buyouts
–Rainscaping
Erosion
–Natural creek bank
stabilization
–Property buyouts
Regional Flooding
–Only potential solution is
large-scale property
buyouts
Should MSD provide full regional
stormwater services?
MSD could be in a position to do something about the impacts of stormwater, if the public approves the funding and mandate. Key Questions:
Which services, if any, are a priority for the community?
How does the public want to pay for services?
–What mechanism?
•Tax? Fee?
–How much?
–How often?
•Monthly? Annually?
–For how long?
Any additional questions?
