All persons engaged in construction activities must implement Best Management Practices (BMPs) for preventing and/or controlling erosion, sedimentation and other construction related impacts to water quality and the environment. A Land Drainage and Alteration Permit (LDAP) is required prior to any disturbance for constructions activities that:
- Disturb an area one acre or greater in size.
- Disturb an area greater than 500 square feet within a sensitive area.
- Disturb 50 cubic yards or greater.
- Disturb any amount of soil for the purpose of supporting a structure.
Sites that are exempt from the permit requirements identified above must achieve the same outcomes and are subject to the same enforcement action as permitted sites.
LDAP Standard Requirements
- No deposit or discharge of sediment onto adjacent properties or water features.
- No degradation of water features due to removal of streambank vegetation.
- No deposit of mud, soil, concrete, or other material into streets or storm drains.
- No exposure of soil or stockpiles to stormwater runoff without containment.
- No earth slides or mudflows shall leave the property.
