This blog post provides an in-depth overview of the new SCM-Design workbook, which replaces the UD-BMP workbook. It discusses the changes, similarities, and functionalities of the workbook, including site assessment, layout, and examples of stormwater management practices.
Welcome to the exploration of the new SCM-Design workbook, a significant update that replaces the previous UD-BMP workbook. This post will delve into the enhancements, features, and functionalities of the workbook, which aims to streamline the design process for stormwater management practices.
The webinar, hosted by Candice Owen and Derek Rapp from Peak Stormwater Engineering, provided insights into the capabilities of the new workbook. The session included a detailed agenda covering changes, similarities, and practical examples of using the workbook effectively.
The SCM-Design workbook was developed in response to substantial updates in the Urban Storm Drainage Criteria Manual, specifically Chapter 4. This chapter had not seen a major update since 2010, necessitating a comprehensive revision to incorporate new practices and technologies in stormwater management.
Some highlights from the updated chapter include:
Despite the updates, many elements from the UD-BMP workbook remain intact:
Several significant changes enhance the workbook's functionality:
The SCM-Design workbook consists of several key components:
The site assessment tab encourages users to consider physical site characteristics, existing amenities, and potential constraints. It includes open-ended questions that help streamline the design process and facilitate communication with reviewers.
The site layout worksheet is where users define outfalls, tributary areas, and select design standards. It allows for multiple outfalls and SCMs, enabling complex designs to be evaluated within a single workbook. Users can also track runoff reduction credits from upstream SCMs.
The webinar included a practical example demonstrating how to modify an existing site with multiple outfalls. The example illustrated:
The new SCM-Design workbook represents a significant advancement in stormwater management design tools. By incorporating user feedback and aligning with updated criteria, it enhances the design process for engineers and reviewers alike. The webinar concluded with an invitation for questions, emphasizing the collaborative nature of this tool's development.
As stormwater management practices continue to evolve, tools like the SCM-Design workbook will play a crucial role in ensuring effective and sustainable designs. Engaging with these resources will help professionals stay informed and equipped to tackle the challenges of urban drainage and water quality management.
