Utilities Focused Asset Management
& Mapping for Parks

Muskingum Watershed Conservancy District (MWCD) Background
Largest watershed in Ohio (8,000 sq. miles / 20% of state)Spanning five counties and portions of 22 othersEstablished in 1933 for flood control after the Great Flood of 1913, Ohio's greatest natural disaster with nearly 500 deathsSystem of 16 dams and reservoirs (all dry dams planned prior to Dust Bowl era)Provided Public's Works projects during depression$8 Billion in flood damage preventedPark system started in 1960's
Atwood Lake ParkCharles Mill Lake ParkPleasant Hill Lake ParkSeneca Lake ParkTappan Lake Park
What is the problem?
Parks are over 50 years old and have endured a variety of modificationsInconsistent record keeping - Information in variety of formats and locationsUnknown utility locationsExcavations can lead to “surprises”Unsafe conditions for construction crews Interruption of utility serviceUnhappy campers

Avoid Expensive ExcavationSimple projects turn into BIG
problems!
Lack of utility knowledge creates additional expenses for future projects
Employee safety and Utility interruption

Current Location Methods
MEMORY?
Current Location MethodsPrints and historical documentsOhio Utilities Protection Service (OUPS) Not for private utilities
Utility Locator (metal only)Utility Camera
Sewer Cam!
Existing Data TypesHistorical data: hand drawings on linens and mylar (1960's-1980's)
CAD design files from expansions (1980's- present)
Misc. field survey data from in-house survey (2001)
Existing in-house CAD engineering drawings
Institutional knowledge - MEMORY
Scanned historical documents
Existing CAD documents
Where is the data?MWCD Engineering Department has majority of plans at Main Office in New Philadelphia, OhioConservation Department has limited amount of plans from easements and projects not directly affecting parksParks keep miscellaneous maps and notes in Maintenance buildings
Additional data stored in off-site location

Goals
Develop a system in which multiple departments can easily access utility dataMaintain data in one location and make available to all staff via the InternetIncrease the amount of sharing of data district-wideIncrease efficiency for Utilities and Construction CrewsMake the information not typically available to field staff by implementing tablets/handheld GPS units, allowing problems to be resolved faster and generating a self- sufficient environmentUncover potential problems
CREATE AND IMPLEMENT A GEOGRAPHIC INFORMATION SYSTEM (GIS)
What is a Geographic Information System or GIS?
GIS combines graphic (maps/CAD data) and non-graphic (dbase/tabular)data
A picture is worth a thousand words…right?!
GIS
How to get data into GIS?
Scan historical drawings and aerials
Georeference & digitize historical data
Georeference past projects and surveys created during construction projects
NEW SURVEY!
Horizontal and Vertical Survey Control
Use standardized local system
Ohio State Plane System – North Zone (NAD83 US Survey Feet-FIPS 3401)
Elevation Datum (NGVD29)
Well monumented for future use
A CORDINATE SYSTEM IS NECCESSARY!!
Permanent MonumentationAll future surveys to utilize new control monuments on
Ohio State Plane Coordinate System
10” Diameter by 42” deep with aluminum cap and
witness post. 10 placed throughout campground
Field survey of the current conditions
Locate ALL utility componentsManholes
Culverts
Water valves/boxes
Electrical boxes
Power Poles
Structures
Field survey environment
4 Day work week: 10 hr. days: Monday-Thursday to minimize disruption to visitors
Signage and safety gear (vests, cones)
Communication with Park Manager & Park Rangers
Field survey - QC/QA
Walk-through of entire project by surveyor with field collected data
Walk-through of first set of deliverables by MWCD staff
Video of area provided for additional checks from office
Contour Video
Contour Video (similar to GoPro) linked to Google Earth
Develop Database Standards and Schema
Review with end-users
Engineering
Water/Waste-water maintenance
Park Managers
Park Maintenance staff
Recreation Management
Database Standards and domains for consistency
Database also to include method of data collection for each entity to determine level of “trust” for each actual location. i.e. Survey Grade, Aerial, CAD, Handheld GPS, Scanned Document, etc.
Database consistency
Create forms for field staff to populate. Use with tablet. Internet service not required for entire duration of task.

Merge historical plans by using the new survey data
End Users - Field Staff
Smart Phone (Android or iOS)Mobile options for quick reference of utility locationsHandheld GPS (Trimble GeoExplorer or Juno) with ArcPAD for improved accuracy IMAGE: http://www.trimble.com/mappingGIS/geo-7-series.aspx
Survey crew to stake-out locations prior to excavation similar to Ohio Utilities Protection Service (OUPS)
End Users - Office StaffArcGIS Desktop for Survey / GIS staff for updates and maintenanceArcGIS ONLINE for non-technical staff in Recreation and Conservation DepartmentsEmbed in MWCD website for construction updatesCreate web applications for MWCD staff as needed
Public – MWCD Website
GIS Desktop & Tablet Demo
Future Maintenance
Future projects and utility installs documentedWork-flow document be createdUtility planning (Project Engineer)Construction (Const. & Utility Crews)As-built survey (Survey Technician)GIS updates (GIS Specialist)MWCD Engineering Dept. consists of Survey and GIS staff to fulfill this need
Benefits of GIS in Park Management
Limit duplication of data capture and maintenance
Consistency with multiple parks
Education/transfer of knowledge
Managing Facilities with current information
Discover or verify suspected problems (I&I)
Simplified Cost Analysis based around
Inflow and Infiltration (I&I)

Lessons LearnedConsultant Communication: Survey staff needs to have understanding of final product
Internal Communication: Maintain constant communication with end-users (primarily park staff)
Project Schedule: Perform fieldwork in off season with less traffic and obstructions
Marathon, not a sprint
