Spring Garden hears CS Davidson on costly Oakridge 3M sewer plan

Feb 12, 2025

CS Davidson presented a DEP‑ordered Act 537 "3M" plan for the Oakridge area affecting 134 lots, estimating total project costs of $6.9M–$8.9M and potential per‑household front‑foot assessments of roughly $44,000–$70,000; the township will seek more time from DEP and hold a public hearing April 1.

CS Davidson engineer Chris Toms told Spring Garden Township commissioners that a DEP order requires an abbreviated Act 537 ("3M") sewage facilities plan for the Oakridge area and that the study shows the project would be expensive and complex. The plan covers roughly 134 residential lots, many of which have cesspools or holding tanks and soils or slopes that preclude new on‑lot systems, Toms said.
