Stormwater Goals  Sustain Stormwater Infrastructure  Begin g an Asset Management approach to managing the City’s  g pp g g y

stormwater system. The practice of  managing  infrastructure  capital assets to  minimize the total  cost of owning and  operating them  while delivering the  desired service  levels. 13

The Solution…

 Stormwater runoff must be managed  The City’s stormwater management system is 

a service provided to customers

 An equitable funding source – A user fee 

system based on impervious area relates fee  directly to user’s impact on stormwater  runoff 19

Stormwater Utility Information  Over 1,400 already established in the U.S.  Used in Illinois  17 Cities currently have a Stormwater Utility, including Champaign, 

Urbana, Bloomington, Normal, Moline, East Moline, Rock Island,  Morton, Rantoul and Collar Counties of Chicago and St. Louis  Several other cities are considering it, including Peoria, Danville, 

Springfield & Decatur

 Dedicated Funding Source  ‐ Needed for obtaining State 

Revolving Loan Funds and issuing bonds.

Work Completed – Step 1   Used aerial imagery to determine pervious vs. 

impervious areas. p  Square footage of impervious area for typical residential 

property = Equivalent Residential Unit (ERU)  In Decatur, 1 ERU = 4,500 sf of impervious surface

23

Work Completed – Step 2  Determined the ERU 

amount on the 34 000+  amount on the 34,000+  parcels within the City of  Decatur  Residential Parcels  All parcels with total area of 1 

acre or less will be considered  as having 1 ERU.  h i    ERU  > 1 acre = Calculated based on  Impervious Area

Work Completed – Step 2  Determined the ERU 

4500 sf

amount on the  34,000+ parcels  within the City of  Decatur  For Non‐residential 

Parcels:  Impervious Area ÷

4,500 = # of ERUs

25

Average Properties in Decatur  Commercial:  Average is approx. 36,000 sf of impervious area or 8 ERUs

Average Commercial:

Average Industrial

 Industrial:  Average is approximately 270,000 sf of impervious area or 60 ERUs

Remaining Work  Billing Database  Credit Manual  For residential and non‐residential  customers   Reduce  stormwater impact = Reduced fee  Public input will be sought before complete  Ranging from 5% to 50% discount  Some credits will be available to a property  without any extra effort:  Zero Runoff from Site  Discharge directly out of the City  Include stormwater detention already

required by City   Hold an Industrial NPDES permit

Work Completed – Step 4 Continued  Properties can invest time or resources to obtain even more 

credits:  Reduce the runoff flow or 

volume more than what is  required  Reduce the amount of  erosion and sediment  leaving the site  Use Green Infrastructure,  like rain gardens or rain  barrels   Teach about stormwater  management (Schools  only) 31

Proposed Recommendation & Schedule  Present Stormwater Utility information to the 

City Council in a Study Session  Present Ordinance for the establishment of a  Stormwater Utility  Three months after Establishment: Phase 1 Utility Service Charge  Base Fee of $3/month per parcel only B  F   f  / h    l  l  Provide 12 month grace period for
