Mobile Businesses and Stormwater Source Control

Presenters – James Packman, Aspect Consulting, Alison Schweitzer

This presentation will cover the progress, challenges, and initial findings from a current Stormwater Action Monitoring(SAM) Study that is a deep dive into stormwater source control and mobile businesses. As a subset of commercial enterprises, mobile businesses have unique challenges related to stormwater and pollution prevention due to their mobile nature and providing services at dispersed sites in multiple jurisdictions. The Study is developing and testing new tools and guidance to support municipal stormwater permittees, including best practices for defining, identifying, and inspecting mobile businesses of interest to stormwater source control, and providing resources for municipal coordination across jurisdictional boundaries.

GIS-based Tools for Prioritizing Pipe Repairs

Presenters – Meiring Borcherds, City of Mukilteo, Erin Nelson, Altaterra Consulting

The use of GIS-based tools to assess stormwater pipe risk and collect and track pipe cleaning and condition assessment status in the field will be demonstrated. These tools are useful for directing limited funding to the highest priority infrastructure repair needs based on risk and potential consequences of pipe failure.

Planning for and Implementing a Phase II Source Control Program in Western Washington

Presenters – Meiring Borcherds, City of Mukilteo, James Packman, Aspect Consulting

This presentation will share City Mukilteo’s approach to preparing for and implementing its source control program, how it managed the challenges to get there, and how the program has been going so far three months since it began.

Resources for Implementing Source Control Inspection Programs

Presenters – Rebecca Dugopolski & Mindy Fohn, Herrera

The Source Control (Business/Site) Inspection Program Guidance Manual funded by the Stormwater Action Monitoring (SAM) program provides resources, templates, and strategies developed based on research, input, and experiences of jurisdictions that have developed similar programs. The 8-chapter hybrid manual is posted on the Washington Stormwater Center website and includes a variety of resources for starting a new inspection program or enhancing an existing program. Four in-person source control inspection trainings were conducted as part of this project in October 2022. This presentation will provide an overview of the collaborative process, manual content, supplemental resources, and training resources (including an online training module).

Real-Time Maintenance Sensing in Stormwater Control Measures

Presenters – John Pedrick, Contech Engineering Solutions

The presentation includes sensor component specifications and sample system output, proposals for integration into stormwater geographic information systems, as well as cost modeling to demonstrate the scalability of the technology. When integrated into a municipal asset management system, this approach can improve the efficiency of inspection and maintenance operations, yielding cost savings and better reliability for effluent water quality.

Pipe Rehabilitation: How to Replace or Rehab 1,000,000 Feet of Pipes

Presenters – Le Nguyen, WSDOT

In the Washington State Department of Transportation, we have miles and miles of aging pipes that need to be replaced or rehabilitated. So far, we have been focusing on upgrading existing culverts to fish-passable culverts. Until recently, we have dealt with many urgent problems due to sinkholes popping up here and there along the highways. I have been studying pipe rehabilitation, the pros, and cons of it, the cost, technical issues, etc., but knowing about pipe rehabilitation alone does not solve the real issue that we need to replace or rehabilitate these pipes as quickly as possible before more and more sinkholes popping up. How are we going to do it as a state agency? Funding is one of the challenges, but it is not the only one. How we identify which pipes to be replaced or rehabilitated, and how we create a mechanism to rehab these pipes effectively in terms of cost, schedule, and impact on the traveling public, just to name a few.

City of Wenatchee Asset Management used to Track Inspection and IDDE

Presenters – Kelsey Grover, City of Wenatchee

The City of Wenatchee uses the Elements Asset Management software to track IDDE, facility inspections, and maintenance. Elements is a web-based, GIS-integrated program that allows staff to record inspections, and maintenance, insert attachments, request follow-up work, and generate reports for both private and publicly owned facilities. This study will focus on using the asset management software for IDDE tracking and follow-up, event-based facility inspections and clean-up, and improved record keeping for Municipal Stormwater Permit compliance. This case study highlights multiple user groups and communication between groups. Additionally, this case will discuss important lessons learned in developing an asset management program.

Asset Management Success for Operation and Maintenance Programs

Presenters – Cory Olson, Snohomish County

Snohomish County implemented Cartegraph OMS in 2016 as its asset management system, used to track work and activities and play a key role in demonstrating compliance with its Municipal Phase I Stormwater permit (NPDES). Our presentations will use examples to show you how to maximize your asset management system, highlight the importance of quality controls, and demonstrate the capacities and benefits of developing and utilizing asset management software to best benefit your organization and meet your program goals.

Using ArcGIS FieldMaps to Conduct Catchbasin Inspections

Presenters – Dave Kangiser, City of Tumwater

The City of Tumwater’s Operation and Maintenance Team recently deployed a catch basin inspection program that utilizes ArcGIS Field Maps. The inspection form was born from a collaboration between the Stormwater Team, Operations and Maintenance Leads, and the GIS Team at the City. Through a modified Value Stream Mapping collaborative process, the teams identified a desired inspection process and created a user-friendly system that simplifies the inspection process and provides visual cues for catch basin maintenance needs. This presentation will review the modified Value Stream Mapping collaboration and demonstrate the Field Maps inspection process for other jurisdictions that are considering alternatives to their current catch basin inspection program.

City of Tacoma: Stormwater Inspections

Presenters – Kevin Brennan, City of Tacoma

The City of Tacoma has a Phase I municipal stormwater permit and is a medium MS4 with a population of approximately 220,000. Tacoma has an established stormwater inspection program that manages a diverse inventory of businesses and SW treatment systems. The following inspection topics are talking points that are great for anyone new to inspections. I hope to share productive and cost-effective inspection approaches that can benefit the inspectors and the businesses they interact with.

Managing a Municipal Stormwater Inspection Program through ArcGIS Online

Presenters – Amber Shows, GHD

This presentation summarizes the manual to the digital transition of the City of Carson’s commercial stormwater inspection program. GHD developed an inspection program that included staff training, and mobile and desktop GIS tools. Of these, the two most important developments were 1) pre-populated digital inspection forms accessed on mobile devices, and 2) a real-time dashboard of program progress and inspection notes and photos.

Management Strategies for Beavers in an MS4

Presenters – Dave Kangiser, City of Tumwater

Tumwater has used several different strategies to successfully keep beaver habitat intact while allowing for stormwater treatment and conveyance. This presentation will explore some of the strategies that are recommended to successfully live with beavers and the many ecosystem benefits that they provide.
