19 ALTERNATIVE NO. 5 Stormwater Credits for Existing Commercial Developments Recent Citizen Complaints (related to Resolution No ) The following property owners have requested at least partial relief from the stormwater assessment The Villages at DeBary (Mildred Piper) American Legion Post 259 (Gene Farrell) American Auto Salvage and Recycling (Kenny Patterson) Evaluate Potential Stormwater Credits Page 19

20 ALTERNATIVE NO. 5 (continued) Stormwater Credits for Existing Commercial Developments Stormwater credits should only be considered for those parcels that provide significant on-site retention volume Pursuant to the City s criteria for landlocked basins (100-year, 24-hour retention volume) Pursuant to the SJRWMD criteria for landlocked basins (25-year, 96-hour Pre versus Post retention volume) What Others are Doing Approximately 50% of communities responding to the FSA Stormwater Utility Survey provide a stormwater credit for private retention and detention facilities The average stormwater credit is approximately 28% Page 20

21 ALTERNATIVE NO. 5 (continued) Stormwater Credits for Existing Commercial Developments Minimum requirements for considering a potential stormwater credit The property owner should be responsible for initiating the request and supplying the requisite information to confirm that the on-site stormwater system is in full compliance with applicable codes and approved permits. Requests should be limited to on-site stormwater systems designed by an engineering professional and permitted through the City and/or State agencies. An inspection report should be prepared to confirm that the on-site stormwater system is ingood operational condition. Additional inspection reports should be provided perpetually and at least biennially. Inspection reports must be signed and sealed by a professional engineer registered in the State of Florida.

22 ALTERNATIVE NO. 5 (continued) Stormwater Credits for Existing Commercial Developments Commercial Parcels (146) Industrial Parcels (103) 249 Total Page 22

23 ALTERNATIVE NO. 5 (continued) Stormwater Credits for Existing Commercial Developments A stormwater credit has been discussed for the commercial and industrial parcels located north of Dirksen Drive and east of the railroad Commercial Improved 29% Residential Vacant 5% Commercial Vacant 1% Residential Improved 65% An across the board stormwater credit of 50% was assumed for the 249 commercial and industrial parcels in this area New assessment rates are required to compensate for the fiscal shortfall resulting from this stormwater credit Page 23

24 ALTERNATIVE NO. 5 (continued) Stormwater Credits for Existing Commercial Developments Commercial parcels generate $587,827 per year (29% of annual revenue) Assume 50% of parcels qualify for a stormwater credit Assume a 25% stormwater credit is allowed for qualified parcels Potential Lost Annual Revenue = $587,827 x 50% x 25% = $73,478/year Page 24

25 ALTERNATIVE NO. 5 (continued) Stormwater Credits for Existing Commercial Developments Suggested Revised Residential Rates to Offset Lost Revenue Categories Current Rates (per year per parcel) Proposed Revised Rates (per year per parcel) Developed Residential Property Accessed by Public Roadways $ $ Developed Residential Property Accessed by Private Roadways $96.00 $ Page 25

26 SUMMARY OF STORMWATER ASSESSMENT ALTERNATIVES #1: Maintain the current ERU based Stormwater Assessment Pros: Adequately funds the entire stormwater program costs Cons: Rate does not take into account the value of the home or the amount of total impervious area #2: Roll-Back the ERU based Stormwater Assessment to Pre-2015 Annual Rates Pros: Lowers the annual assessment by 65% Cons: Eliminates critical items necessary to maintain the existing stormwater infrastructure Page 26

27 SUMMARY OF STORMWATER ASSESSMENT ALTERNATIVES (continued) #3: Roll-Back the ERU based Stormwater Assessment and Increase the Millage to Offset the Reduced Revenue Pros: - Maintains revenue and funds stormwater program costs - Some homeowners will experience a reduction in annual costs Cons: - Homestead-exempted parcels will not pay their fair share - Some homeowners will experience an increase in annual cost Page 27

28 SUMMARY OF STORMWATER ASSESSMENT ALTERNATIVES (continued) #4: Implement an EBU based Stormwater Assessment Tiered Approach for Residential and Commercial Pros: - Maintains revenue and funds stormwater program costs - Some homeowners will experience a reduction in annual costs Cons: - Difficult to administer - Some homeowners will experience an increase in annual costs Page 28

29 SUMMARY OF STORMWATER ASSESSMENT ALTERNATIVES (continued) #5: Implement Stormwater Credits for Commercial Development and Increase the Residential Annual Rate to Offset the Reduced Revenue Pros Will benefit a few commercial and industrial parcels Cons Residential homeowners will experience an increase to offset the lost revenue Page 29
