SAW Grants Effective Approaches for
Stormwater AMPs and SMPs

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
Identify major problems
Develop CIP
Represents one point in time
Static document: sits on shelf
Updated every 20 or so years
Asset Management Plan (SAW)
Identifies condition of all assets
Develop Cost Structure
Continuous process
Integrated with GIS and CCMMS
Continuously updated
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

Manhole Inspections
Plan for about 20-25 MH/day
Cold weather ok, but generally
not below 25-30 degrees (F)
MACP compliant coding
Old Data Collection and
Assessment Methods
• Digital Camera
• Only used for special circumstances
• Required confined space entry
GPS Unit
Pen and Paper
Tedious Data Transfer Step
Data Collection Options
• Uses a mobile app to
collect data from any smart
device
• ESRI cloud based
application
• Cost per license: Varies
based on credits.
• Uses a mobile app to
collect data from any
smart device
• Trimble cloud based
application
• Cost per license:
$250/user per year
Terraflex Applications
• Data Inventory
• Streambank Assessment
• MACP Compliant Manhole Assessments
• Retention/Detention Pond Inventories
• Culvert Inspections
• Dam Assessment
• Bridge Inventory/Inspections
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

Future Funding for Stormwater
• Impervious area
measurement
• Identify key potential
ratepayers
• Establish Equivalent

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
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
