PROJECT BACKGROUND

Reconstruction of the Mill Creek water control structure (WCS) is a key part of the 1100-acre Herring River Restoration Project (HRRP), a high-profile project with many federal, state, and local partners.

PROJECT BACKGROUND

Mill Creek Water Control Structure

The WCS will allow control of tidal exchange within the Mill Creek subbasin and thereby

• Prevent tidal flooding of nearby private properties

• Restore approximately 60 acres of Mill Creek salt marshes.

• Allow higher tides, and a greater degree of restoration, throughout the remainder of the 1100-acre project area.

PROJECT SCOPE

• Erosion & sediment control measures, including turbidity curtain

• Site clearing, vegetation removal

• Cofferdam construction

• Dewatering basin, diversion piping

• Gravel access road construction, including wetland crossing

(articulated concrete block matting)

• Water control structure construction

• sheet pile wall with concrete cap

• precast modular concrete block retaining wall

• 5 water control gates and power control system

• Tidal channel dredging – Offsite disposal

• Tidal channel dredging – Beneficial reuse*

• Reseeding disturbed areas

*In accordance with NPS soil handling protocol, testing

SITE CONDITIONS/CONSTRAINTS

Work in Tidal Environment
