Green Infrastructure and Regional Stormwater Capture Project Concept Designs
DEVELOPING IMPLEMENTATION-READY CONCEPT DESIGNS FOR LID, GREEN STREET AND REGIONAL STORMWATER CAPTURE PROJECTS
End Client: City of Alhambra, CA
Paradigm created multiple concepts to support funding applications for low impact development, green street and regional stormwater capture projects. Paradigm coordinated with the city to identify available parcels and appropriate streets for project implementation. LID projects include a public parking lot and two pocket parks where stormwater could be intercepted. The green street concept identified a site where runoff from relatively large areas could be intercepted (see rendering below). Each site was evaluated for its potential to capture stormwater, based on footprint and drainage area, to maximize cost effectiveness. Hydrology analysis was used to identify project sizing requirements based on a design storm of approximately 1-inch rainfall in 24 hours.
Paradigm closely collaborated with the city to deliver messaging that is relevant to the community and potential funding organizations. Each project received a compact fact sheet with illustrations on the sizing analysis, layout, cost estimation and 3-dimensional rendering. AutoCAD and Infraworks360 were used for drawings and renderings, which will be key elements of future funding applications. A clear analysis was presented to illustrate how the projects will address the City’s regulatory requirements for TMDL implementation. The developed concepts will be key to the moving forward the City’s stormwater program, allowing them to efficiently apply for access potential funding sources while demonstrating progress to regulatory agencies.
