When Green Turns to Blue: Integrating Roof Stormwater Management Solutions
Strategies and Design Considerations for Successful Implementation
Sponsored by GAF | Siplast | Presented by Rick Kile and Tim Clepper, RRC, RRO

Large scale storm events are becoming increasingly common. Local municipalities are tasked with implementing stormwater management requirements into their codes to help reduce the impact of large precipitation events on their communities. The challenges are twofold for the design team: understanding the local stormwater management code and what strategies can be implemented to meet both retention and detention-based requirements. This presentation will explore how to identify projects that may be good candidates for on-structure or rooftop stormwater management, tools that can help meet water management challenges and how they can be incorporated into the overburden assemblies we already specify. Finally, we’ll review a few projects which have successfully employed these methods to help meet their stormwater management requirements.
