12.4.2.1 Nonstructural Practices Since the number of potential nonstructural BMPs to
be implemented is very large, initial screening is useful before the final selection process.
The regulatory and source control BMP descriptions contained later in this chapter focus
on the most commonly implemented practices; other, less commonly used practices, how-
ever, also could be considered. In addition, each practice (e.g., solid waste management)
can be divided into numerous subpractices (e.g., management of leaf litter, rubbish,
garbage, and lawn clippings). In an urban runoff management plan for the Santa Clara
Valley, for example, the consultants identified more than 100 separate potential nonstruc-
tural BMPs used throughout the country. Municipalities, therefore, have to screen regula-
tory and source control BMPs based on their particular watershed.
