Runoff and BMP expectations by site type

Office towers often drain to public way and storm systems with strict expectations about what leaves the site. Plan berms, intake protection, and diversion early.

Hotels add porte cochere and sidewalk guest flow. Wash water that looks fine on a loading dock is a problem under a canopy at checkout time.

Campuses and portfolios want repeatable BMPs so the third visit looks like the first. Standardize the notes: drain map, collection method, chemistry log.

When local rules are unclear, escalate before mobilization. Guessing on wash water is more expensive than a phone call to the property’s EHS contact.
