The debate over green and gray technologies for stormwater management is a heated one. Designers, developers, municipalities, regulatory agencies; everyone is asking the same question - Green, Gray or a mix? Current sustainable infrastructure selection criteria include: effectiveness, installation, construction costs, and lifecycle costs, including planning, design, operation and maintenance, and replacement.

This presentation will discuss the options available for green and gray infrastructure evaluation and cost analysis. There will be three expert speakers as part of this webinar. Case studies will be presented to demonstrate how these tools were applied for green-gray infrastructure analysis, and what the real world impacts could be for each case study. 

This presentation is designed for designers, developers, municipalities, and regulatory agencies.
