In addition, no erosion or discharge of silt or larger particles from erosion control measures, surface runoff, or construction dewatering shall occur onto adjacent properties, or into sewers or drains.

c. Construction of dewatering sumps and connecting dewatering trenches as necessary for construction operations. These sumps and trenches shall be of size, configuration and elevation as necessary to draw groundwater below the excavation subgrade levels.

Special siltation control details may have to be submitted to the Engineer for approval.

d. Damaged or loose siltation fence shall be replaced as necessary to maintain their function of controlling erosion siltation. Damaged or broken down stone check dams

Massena, New York

Site Clearing 311000 - 5 and filtration dams shall be replaced immediately.
