Along with the Construction Certification Package, the Philadelphia Water Department (PWD) requires that Record Drawing(s) be submitted at the close of the project to ensure that the stormwater management practices (SMPs) and their elements were constructed in general accordance with the Approved Post‑Construction Stormwater Management Plan (PCSMP), and to document any field changes. Record Drawing(s) are required for SMP verification and are a key component of PWD’s compliance reporting and post-construction inspection procedures. Samples demonstrating how Approved PCSMP plan sheets should be marked-up in order to prepare Record Drawings are provided in Appendix K.
