Land development and construction of new homes, shopping center, industries, and roads removed vegetation and uncovers soils.
Regrading the site may make the soil even more susceptible to erosion if not properly stabilized. After development, there
are more buildings, roads and lawns. This increase in impervious surfaces causes more stormwater runoff and NPS pollution
of the Codorus Creek.

BEST MANAGEMENT PRACTICES
Rain gardens infiltrate and treat stormwater onsite
Urban BMPs are designed to prevent pre- and post-construction NPS pollution. They include:
* Adopting effective municipal ordinances
* Open space preservation
* Stream corridor protection
* Erosion & sediment controls
* Stormwater management
* Low impact development
* Conservation by design
* Good housekeeping practices
