The District of Columbia (District), like most ultra-urban areas, experiences increased stormwater runoff that results from development. This runoff places a burden on sewer systems and degrades aquatic resources when it is not managed adequately. Recognizing this issue, the District first adopted stormwater management regulations in 1988. These regulations, Chapter 5 of Title 21 of the District of Columbia Municipal Regulations (21 DCMR), established requirements to manage both stormwater quality and quantity. The Department of Energy and Environment (DOEE) envisions a city whose rivers and waters are fishable and swimmable for all. One way in which DOEE aims to achieve this goal is increasing the maintenance frequency of stormwater best management practices (BMP). The Self-Inspection & Self-Reporting (SISR) program, developed in 2018, is an effort to maintain stormwater BMPs more consistently by enlisting their owners to perform necessary inspections of their own facilities.
