TTF Ethel Jordan Park

Project details

  • Project Name: TTF Ethel Jordan Park
  • Project Client: Tookany/Tacony-Frankford Watershed Partnership
  • Project Location: Abington Township, Montgomery County, Pennsylvania

A.D. Marble provided stream restoration design services for approximately 50 linear feet of Jenkintown Creek immediately downstream of the culvert under Cadwalader Avenue on the northwest corner of the Ethel Jordan Park property. In order to properly size the stream restoration techniques, the U.S. Geological Survey (USGS) StreamStats Application was used to determine peak flows for various storm events. The stream restoration design focused on stabilizing the stream bank by utilizing a combination of rock toe protection, grading, native plantings, and live willow stakes. Given the surrounding residential neighborhood and the current use as a public park, all efforts were made to keep the stream design aesthetically pleasing as well as functional.

The proposed stormwater management concept had two areas of concentration. The first area was a rain garden designed immediately adjacent to Cadwalader Avenue. The second area was a bioswale located along Osceola Avenue. The best management practices (BMPs) were designed to meet the Rev, WQv, and channel protection volume requirements, but were not specifically designed to meet the flood control requirements outlined in the Act 167 Plan. A.D. Marble performed infiltration tests for the rain garden and bioswale. The plan set included an existing conditions plan, grading plan, general notes, typical details, cross sections, and erosion and sediment pollution control plans. In addition to the plans, a brief stormwater management narrative was prepared to outline the benefits from the proposed BMPs.
