Integrative Stormwater Design & Impacts of Development In the Floodplains

Published on

PRESENTED BY: Joshua Lippert, City of Pittsburgh Planning Department and Claudia Saladin, ASLA, LEED AP BD+C, ND, Strada Architecture LLC

In Pittsburgh, with some of the wettest weather and the most iconic rivers in the country, there’s a need to treat and infiltrate stormwater on site as well as responsibly develop along streams and rivers to mitigate flood hazards, which is an important factor to future development. Oriented to designers and project managers, this training will outline Pittsburgh’s stormwater management requirements and the floodplain overlay ordinance for private property. It will include a case study of the district-wide approach to stormwater management at the Bakery Square 2.0 redevelopment project and highlight the early inclusion of stormwater and floodplain design on small- to large-scale projects.

Additionally, various strategies for managing stormwater will be discussed as well as site conditions that affect facility size and configuration. Information on how to document stormwater plans in a design report will be provided with suggestions on how to efficiently convey stormwater concepts to reviewers. The required Maintenance Plan also will be reviewed. In terms of floodplain ordinance, presenters will cover conditions of different land uses, renovations, and new construction. They also will advise on how to complete the floodplain overlay development permit application.

  26. 26. What is the Special Flood Hazard Area? ‘Living with floods involves two broad activities: better managing the risks and taking steps to reduce our vulnerability, and better managing the land- scape to reduce the magnitude of destructive power of floods. ‘ --Connie Mutel, A Watershed Yean Anatomy oi Iowa Floods of 2008 FLOOD HAZARD AREA 1% Annual Chance Flood Event Flood-prone areas are managed by restricting development in the floodway, but allowing development in the floodway fringe. Rural areas produce flood causing runoff at a slower rate than do urban areas.
