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.
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?
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
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
Ultimate Goal
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
Sewer Televising Strategy Good cross section of sewer ages and sizes County drains (enclosed systems) Adequate sampling of system TELEVISE FIRST strategy
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
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 -> http://www.redzone.com/redzone-products/

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
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
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

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
