In contrast, the Tide gate can EH DGMXVWHG WR DOORZ RZ LQWR WKH FXOYHUW thereby feeding essential tide waters to the channel or marsh behind the dike. Because the Tide gate is located on the outfall or WLGDO VLGH RI WKH KHDGZDOO LWV RDW V\VWHP responds to any tidal change allowing the predetermined amount of water in and closing to incoming water when the tide reaches the design high water level. With the storm tide water elevation, the Tide gate closes early thereby preserving a relatively large volume of potential water storage capacity behind the dike should it be needed for detention of upland runoff associated with the coastal storm.

Frame width and height shall be no larger than the outside dimensions of the Box Culvert. gate shall include neoprene compression seals between the gate and gate frame. Provide all components shown on the Contract Drawings and those needed for proper gate actuation All 316 stainless steel mounting hardware shall be included. Side-hinged Tidal Actuated Control gate shall be initially opened using a hydraulic cylinder, crank arm, hydraulic lines, and hydraulic control box as shown on the Contract Drawings.

4 Normal operation Hydraulic controls shall be housed in a locking, NEMA 4X stainless steel tamper-proof box. Upper and lower gate hinge bearings shall be Gar-Max or equal. Side-hinged Tidal Actuated Control gate shall connection to the hydraulic control box as shown shall result in release of hydraulic system pressure to components such that gate closure will occur on hinge tube mounting shall be orientated in an to facilitate gate closure when the gate hydraulic system pressure is released. gate opening swing shall provide for a maximum gate opening angle of 70 degrees prior to hydraulic cylinder actuation. Operating Principles gate start position is fully closed ( gate seated point. In this condition the gate prevents the intrusion of salt water upstream of the closed gate . of tide elevation; this allows drainage during high the degree of open position and continuously locks-out gate closure for every increment of increased degree of opening to a maximum of seventy degrees.)

As the tide elevation increases there is an exchange through the gate of tidal and creek (stream, river, hydraulic cylinder and allows free movement of the gate in the closing direction.
