1 SAW Grants Effective Approaches for Stormwater AMPs and SMPs Gregory Kacvinsky, P.E. MWEA Annual Conference June 22, 2015 OHM-ADVISORS.COM ARCHITECTS. ENGINEERS. PLANNERS.

2 SAW: Ready, Set, GO! First round of grant recipients have gone more than a full year (less than 2 years left!) A lot of data collection required how can we get it all done in time?

3 Still Waiting? Only two rounds in so far Stormwater AMPs: $116 million Stormwater Mgt. Plans: $26 million Vast majority of SAW work has yet to be awarded or contracted

5 This is NOT a Master Plan Conventional Master Plan Asset Management Plan (SAW) Identify major problems Identifies condition of all assets Develop CIP Develop Cost Structure Represents one point in time Continuous process Static document: sits on shelf Integrated with GIS and CCMMS Updated every 20 or so years Continuously updated

6 Ultimate Goal

7 Key Components Smart, targeted physical evaluation of assets Modeling (optional) Marrying the hard assets (pipes and manholes) with the soft assets (ponds, channels, BMPs) Compelling case for local funding

8 Sewer Televising Strategy Good cross section of sewer ages and sizes County drains (enclosed systems) Adequate sampling of system TELEVISE FIRST strategy

9 Televise to Clean Conventional practice is Cleaning to Televise Most sewers are self cleaning and do not need to be cleaned in order to be televised Televise as much sewer as possible Flag the segments that were unable to be assessed

10 Multi-Sensor Inspection (MSI) Combines conventional qualitative CCTV with synchronized laser and sonar dimension information Provides a unique full 360 quantitative view of the pipeline Uses 3D LIDAR and SONAR data to generate a 3D model of the pipe and associated engineering reports Source: RedZone Robotics ->

12 Manhole Inspections

13 Manhole Inspections

14 Manhole Inspections Plan for about MH/day Cold weather ok, but generally not below degrees (F) MACP compliant coding

15 Field Equipment

16 Old Data Collection and Assessment Methods GPS Unit Tedious Data Transfer Step Pen and Paper Digital Camera Only used for special circumstances Required confined space entry

17 Old Inspection Forms

18 New technology improves the process Verizon MiFi Jetpack Garmin GLO Apple ipad Samsung Galaxy Tab S

19 Data Collection Options Uses a mobile app to collect data from any smart device Trimble cloud based application Cost per license: $250/user per year Uses a mobile app to collect data from any smart device ESRI cloud based application Cost per license: Varies based on credits.

26 Future Funding for Stormwater Reviewing local storm water budgets: Most programs are covered by injections from the General Fund Budgets often cover only major repair projects (i.e. County Drain projects) Little to no funding for preventative maintenance Over-reliance on grants

27 Stormwater Budget: Pre-SAW Stormwater Expense 2015 Salaries & Wages $59,079 Fringe Benefits $27,437 Supplies $1,500 Debt Service $148,504 Other Expenses $11,160 Total $247,680

28 Stormwater Budget: Post-SAW Stormwater Expense 2015 PW Admin & Salaries $100,000 Information Services/GIS $20,000 Storm System Capital Improvements $125,000 Current Stormwater Budget: $248,000 Roadway Sweeping $65,000 REAL Stormwater Costs: $900,000 Stormwater Component of Road Projects $200,000 Collection System Maintenance $180,000 Difference ~$650,000 (3.6X existing budget) Road Bridge Projects $35,000 Other Projects & Programs $25,000 Debt Service $150,000 Total $900,000

29 Future Funding for Stormwater Impervious area measurement Identify key potential ratepayers Establish Equivalent Residential Unit (ERU)

30 Impervious Area (sq. ft.) Future Funding for Stormwater ZONING DISTRICTS R-2,3,4 Impervious Area Parcel Impervious Area Average Impervious Average Impervious Area: 4,024 sq. ft. Confidence: ± 98 sq. ft of 15,159 Parcels Sampled

31 Future Funding for Stormwater Equivalent Residential Unit (ERU) Calculations Top 15 Rate Payers Impervious Area (sq. ft.) No. of ERU's Percent of Total ERU's School District 7,452,670 1, % City-Owned Property 4,851,234 1, % Local University 3,819, % ABC Associates 3,016, % New Plan Hampton Village LLC 2,650, % Mrg Avon LLC & Crest Avon LLC 2,289, % Good Will Co Inc 1,632, % Associate Estates Realty Cor 1,261, % Singh Cider Mill Village LLC 1,226, % First Industrial Realty Trust Inc 1,184, % Ramco-Gershenson Properties LP 1,181, % 1185 River Oaks North LLC 1,158, % Laura K Bradshaw Tucker 1,124, % Wal Mart 1,041, % Meijer, Inc. 1,025, % No. of Lots No. of ERU's Percent of Total ERU's Single Family Residential (R1) 3,810 4, % Single Family Residential (R2,R3,R4) 15,159 15, % Single Family Residential (RE) % Impervious Area (sq. ft.)

32 Future Funding for Stormwater Like wastewater, stormwater needs a long term view of the impact of O&M Without an increase in funding, systems WILL fail Asset Management Plan will visualize this

33 Future Funding for Stormwater

34 Future Funding for Stormwater Source: 2014 Stormwater Utility Survey Western Kentucky University

35 Stormwater SAW Recap Critical to embrace new methods to collect data in field (tablet-to-gis) Televise first (CCTV strategy) Develop a case for dedicated funding, and leverage the Asset Management Plan to make it compelling
