Town of Moraga Storm Drain O&M ProgramDeveloping a Storm Drain GIS

Outline

• Part I – Storm Drain Mapping – Morning– Town of Moraga – Data collection, equipment, procedures– Field – storm drain mapping

• Part II – Create Final GIS – Afternoon – Demo

• Download data• Data processing and analysis• GIS web map

Case Study – Town of Moraga

Aging Infrastructure

Key Questions

• How do we prioritize resources (dollars and staff time) – Maintenance, repair, and 

capital improvement projects• Information needs

– What do we have?– Where are they located?– What condition are they in?– How is the system 

connected?

Desired Outcomes

• Evaluate existing storm drain system GIS • Develop prioritized list for maintenance, repair, and capital investment

• Establish procedures for O&M Program including developing a web GIS

Existing SD System

• 85% spatially complete

• 50% attributes populated

• Existing data had limited field verification

• Need to complete an asset inventory!!!

What we did:

• Project Development Plan– Proposed Geodatabase to answer

Key Questions– Field data collection preparation 

and procedures– Data Management– Quality Control Procedures– Features Guide– Health and Safety Plan

What we did:

• Office and Field Training:– Features Guide– Data collection procedures– General Safety Procedures– Practice day in field with all crews together

What is ArcGIS Online

• ArcGIS Online is ESRI’s web based GIS system

• Data can be managed and edited• Can share data with the public• Can perform elementary tools and analysis that local governments need

Why ArcGIS Online

• There are many different options when it comes to GIS

• ESRI is the industry standard– Students are trained in it– Very versatile– Great for data collection– Lot of resources to help

• After this do this with other fields like pipe condition and pipe depth

• You are going to want to make a whole new feature layer for nodes

• Now the last step is to make a new map and connect the feature layers to the map 

• Collector then connects to the map to start collecting field data

How Data is Brought Back From the Field

• I collected my data, where is it now?

What a Finished Web Map/App Can Look Like

• Finished web maps has the capabilities for– Editing data– Knowing existing data– Sharing with the public and with people in your organization 

What a Finished Web Map/App Can Look Like

• Pop‐ups– Provide data for each feature

– Can be edited to show maintenance updates
