PHILADELPHIA, PA (STORMWATER MANAGEMENT) - Rodriguez Consulting LLC (Rodriguez) teamed with Paulus, Sokolowski & Sartor (PS&S) was retained by the Philadelphia Zoo (Zoo) to provide general engineering services to the Zoo to assist with various stormwater management issues including the replacement of antiquated storm/sanitary sewer infrastructure and increase the capacity of the system by re-circulating Bird Lake through a wetland.  This reduces the amount of water in the storm sewer system by approximately 200,000 gallons per day.

Rodriguez's survey crew performed a site survey and field investigation of two areas within the Zoo in order to gather topographic and existing conditions information regarding drainage features.
  • McNeil Avian Center – Rood Drain Design – Rodriguez created design plans proposing solutions to manage flooding problems at the McNeil Avian Center due to deficiencies with roof drains.  Designs proposed to disconnect drains from the combined sewer system and discharge rain water into the adjacent Bird Lake via an outfall pipe and rip rap apron.
  • Children's Zoo – Inlet and Storm Sewer Design – Rodriguez coordinated with the Philadelphia Water Department to video inspect the existing combined sewer and stormwater inlets to determine the source of the flooding problems.  Design plans were created that proposed the construction of three new stormwater inlets and new 18” RCP storm drain that would improve drainage at this area and would be Philadelphia Water Department standards.

Estimated Cost

  • Design Services: $10K
  • Construction Services: $55K
