Public Works Stormwater Summit Day Two: Operations & Maintenance

Stormwater Operations and Maintenance

The presentations on Day Two of the Public Works Stormwater Summit feature case studies on best practices for the operation and maintenance of stormwater management programs.

Greening the Los Angeles Public Right-of-Way by Prioritizing Green Stormwater Infrastructure
The City of Los Angeles estimates that it is looking at roughly $20 billion in stormwater compliance costs. In an effort to employ a more targeted and comprehensive approach that goes above and beyond the minimum MS4 permit regulations, the City is developing an inter-departmental strategy for green stormwater infrastructure (GSI) and low impact development (LID) within the public right-of-way. 

Learning Objectives: At the conclusion of this session, you will be better able to:
1.Establish guidelines and processes for GSI/LID with the public right-of-way.
2.Develop a sustainable framework for public works construction projects using green stormwater infrastructure (GSI) principles.
3.Build infrastructure that provides heat island reduction and minimizes flood risk to ensure these assets are more resilient.

A Green Infrastructure Framework for Metro Kansas City
The Mid-America Regional Council (MARC) Green Infrastructure Framework provides a regional strategy, which expands the definition of green infrastructure (GI) to incorporate the use of integrated nature-based solutions. The framework uses an integrated systems approach to address ecological services across sites, stakeholder interests, communities and ecological conditions. 

Learning Objectives: At the conclusion of this session, you will be better able to:
1.Encourage creative approaches to green infrastructure planning.
2.Apply network design principles to green infrastructure design.
3.Use green infrastructure design principles for multiple contexts and stakeholder groups.

Design and Construction of Green Infrastructure (GI) in Historic Industrial Areas The City of Kansas City, Missouri’s Central Industrial District (CID)
West Bottoms was established in the mid-1800s at the confluence of the Kansas and Missouri Rivers and served as an industrial hub until multiple catastrophic floods and economic downturns sent the area into decline over the last half of the Twentieth Century. In the last 10 years, there’s been a resurgence of development. The City’s CID green infrastructure (GI) project aims to foster more redevelopment by implementing GI solutions to reduce the total volume of stormwater entering the Santa Fe Pump Station which drains most of the West Bottoms to the Westside Wastewater Treatment Plant and the Missouri River.

Learning Objectives: At the conclusion of this session, you will be better able to:
1.List the differences between stormwater management for combined sewer system overflows (CSOs) and single system sewer overflows (SSOs).
2.Discuss the challenges of design and construction of green infrastructure in historic combined sewer system overflow (CSOs) areas.
3.Engage the public and stakeholders to support a green infrastructure project. 

Innovative Structural BMP Management
The City of San Diego, California, is using three innovations for structural BMP inspection and maintenance: 1) Infiltrometers to inspect porous pavement and bio-retention areas, 2) power washing to unclog porous pavements, and 3) setting up an effective sweeper schedule or porous pavement.

Learning Objectives: At the conclusion of this session, you will be better able to:
1.Identify the steps for unclogging porous pavement.
2.Evaluate porous pavement and bio-retention PMP functionality using an infiltrometer.
3.Develop an effective sweeper schedule for your porous pavement assets.

Make It Count: Private Stormwater Facility Maintenance Inspection Program
The City of Vancouver, Washington’s Water Resource Protection Program began a private stormwater facility inspection and maintenance program in 2016. The City used existing asset management software and GIS mapping systems to facilitate a consistent, transparent inspection process and tools to communicate with facility owners and property managers.

Learning Objectives: At the conclusion of this session, you will be better able to:
1.Implement an asset management-based approach for private stormwater facility inspection program.
2.Identify the most common and most costly private stormwater facility deficiencies.
3.Recognize the value of including the maintenance perspective into design and engineering processing and permits. Q&A with Water Resources Management Committee
