2020 Webcast Series 

Webcast 1: Climate Resilience   March 18, 2020, 12:00-1:30 PM CST  

Coastal communities are under pressure to protect the health and safety of their residents from storms and other natural disasters. Many of these communities are turning to green infrastructure and natural resources as a potential solution. In this webcast, NOAA’s Office for Coastal Management will present accessible and ready to use resources that planners and natural resource managers can use to build more resilient communities. This includes the newly released “Adapting Stormwater Management for Coastal Floods.” With this tool, communities derive coastal water level thresholds and assess potential impacts on stormwater infrastructure in future flood scenarios.   Participants will also hear about other green infrastructure resources including a green infrastructure effectiveness database, a tool to acquire points for open space in the Community Rating System, as well as data and other training resources. All of these resources are freely available on NOAA’s Digital Coast website, created for the coastal management community in partnership with professional organizations and nonprofits.

Webcast 2: TMDL Planning and Implementation   April 29, 2020, 12:00-1:30 PM CST  

Often, larger regional TMDLs are “nested” with local TMDLs that address local impairments (e.g., for bacteria, biological standards, dissolved oxygen, local pollutants).  The pollutants of concern are often different for the regional and local TMDLs. Several important questions emerge out of these situations.  How do large, regional TMDLs translate to planning and implementation at smaller scales, such as states and local governments?  If TMDLs are nested, how do the TMDLs at different scales “talk to each other,” and how can communities target the most effective suite of BMPs to address TMDLs at all levels.  This webcast will explore the issue of regional and nested TMDLs and how analytical tools are emerging to integrate, and coordinate management practices implemented at the local and regional levels.

Webcast 3: Small Scale BMPs   May 20, 2020, 12:00-1:30 PM CST  

Finding cost-effective stormwater retrofits in urban landscapes can be challenging and demands “staying with the problem.”  In addition to all the usual suspects of limited space, utilities, disturbed soils, and expensive real-estate, it is often hard to design these retrofits with enough storage to capture the desired rainfall depth from the drainage area.  However, these small retrofits are often the only opportunity to provide treatment in more urban landscapes. In this webcast, we will look at innovations to enhance rainfall capture and treatment in practices suited for smaller spaces.

Webcast 4: Source Water Impacts - Urbanization and Protection   June 24, 2020, 12:00-1:30 PM CST  

Protection of surface and groundwater sources is essential to public health protection. Recently America’s Water Infrastructure Act (AWIA) was signed into law. The law requires community (drinking) water systems serving more than 3,300 people to develop or update risk assessments and emergency response plans (ERPs). With this in mind, communities are looking to develop Source Water Protection plans and identify tools to mitigate the effects of development and possible pollutant producing behaviors in drinking water watersheds. This webcast will look at planning level tools and review how some communities have addressed their source water protection requirements.

Webcast 5: IDDE - New Technologies and Techniques   September 16, 2020, 12:00-1:30 PM CST  

Illicit discharges are finally being recognized for playing a major role in contributing to water quality impairments as a substantial contributor of bacteria, nutrients and other pollutants in some watersheds. Recent research has shown that the problems emanating from these sources may be larger than we have imagined. However, controlling these substances through programs such as illicit discharge detection and elimination (IDDE) may be one of the easier, less expensive options for meeting contaminant load reductions. This webcast will look at the recent innovations in best practices to control illicit discharges and gross stormwater solids and provide some case studies to illustrate the quantifiable pollutant load reduction benefits for water quality of these cost-effective stormwater BMPs.

Webcast 6: Watershed Modeling   October 21, 2020, 12:00-1:30 PM CST  

Modeling is frequently used in watershed and stormwater planning to help build an understanding of a problem or calculate possible changes over time when monitoring is not an option. Modeling can also be used to compare courses of action to determine effective strategies for addressing a problem and the potential cost for each strategy. Non-point source modeling tools are an important tool in estimating compliance with TMDL allocations and developing an overall watershed plan to meet water quality. In this webcast, we will look at several tools for estimating pollutant loads, discuss the possible applications, and look at case studies to illustrate how a model was employed to achieve the desired goals.

Webcast 7: Watershed Based Planning Techniques   November 18, 2020, 12:00-1:30 PM CST  

A watershed-based planning approach is effective in tying together multiple community objectives including managing stormwater, improving water quality, protecting high-quality natural resources, and providing for public recreation. A comprehensive watershed plan allows communities to identify watershed restoration priorities, highlight flood mitigation and stormwater retrofits projects to meet regulatory goals such as TMDLs, and achieve compliance with federal and state permits.  Techniques such as Better Site Design (BSD) and environmental site design (ESD), conservation easements, land-use designations, zoning, and PDR or TDR programs can play a role in creating management plans at the watershed scale. In this webcast, we will look at these techniques and learn from some case studies how watershed-level planning has benefitted a community in meeting their restoration objectives.

Webcast 8: Asset Management   December 9, 2020, 12:00-1:30 PM CST  

Asset Management is a popular strategy for maintaining the level of service for Water and Wastewater Systems that has increased its visibility in the stormwater management field as water quality regulations have proliferated. Asset Management provides a structured approach to optimizing life-cycle costs by developing a proactive long-term management strategy of stormwater infrastructures such as pipes, catch basins, and outfalls, as well as green infrastructure practices that require long term maintenance. In this webcast, we will look at how some communities have incorporated an asset management strategy into their stormwater management programs.
