2-5-2 Example Project Descriptions By Application Type:

A. Access Channel:

1. An access channel will be excavated along the (north) bank of the river to provide access for a proposed marina development. The channel will be approximately 300' long, 100' wide and will be excavated to a depth of 15' below the existing grade. It will have 2:1 side slopes which will be stabilized with end dumped riprap placed over a geotextile fabric and filter layer. Fill removed from the excavation will be hauled to a disposal site located outside of the floodway where it will be graded and seeded. The construction will require the excavation of 11,700 yd³ of material followed by maintenance dredging on an as needed basis. During construction an earthen plug will separate the river from the channel. Once the excavation has been completed and stabilized, the plug will be removed and the channel flooded. Plans, specifications and color photographs are enclosed in the application package.

B. Construction In A Floodway:

1. Bank Protection - Riprap (view example bank stabilization plan) | (view example steel piling or vinyl seawall plan for streams)

Approximately 250' of Eagle Creek's eroded streambank will be stabilized with end dumped riprap placed over a geotextile fabric to protect the bank from further erosion. The riprap will be keyed into the streambed at its base and will conform to the existing bank at the project limits. It will have a maximum height of 5', a maximum streamward projection of 2' beyond the existing bank, and 1:1 sideslopes. Plans, specifications and color photographs are enclosed in the application package.

2. Bank Protection - Seawall

An existing, deteriorated, wooden seawall will be replaced with a new steel sheet piling seawall along 150' of the riverbank to deter bank erosion. The new wall will be approximately 4' high, as measured from the riverbed, will have the same alignment as the existing wall, and will tie into existing seawalls located on adjacent properties located to the east and the west. The piling will be driven approximately 10' into the riverbed and will be anchored with deadmen spaced at 15' intervals. A whaler will be placed across the face of the wall to further stabilize the sheet piling. Clean fill will be brought onsite to backfill the area landward of the new seawall. The fill will be leveled with the top of the wall at the river and will be tapered back to existing ground elevations within the project site. Plans, specifications and color photographs are enclosed in the application package.

3. Bridge - New (view example bridge project plan)

A new bridge will be constructed over Indian Creek to carry the extension of Oakmont Avenue across the stream. The new structure will be a single span continuous prestressed concrete I-beam bridge with span length of 70'. The structure will have an out-to-out length of 80' and a clear roadway width of 35'. The spill through abutments will have 2:1 sideslopes armored with limestone riprap placed over a geotextile fabric. The abutments and piers will be skewed 10° to align with streamflow. The approach roads will be elevated a maximum of 3.5' above the existing grade. A temporary construction access crossing will be placed within the right-of-way on the downstream (west) side of the proposed bridge. It will be completely removed from the floodway upon completion of the bridge. The project is entirely federally funded. Plans, specifications and color photographs are enclosed in the application package.

4. Bridge - Replacement (view example bridge project plan)

The existing steel truss bridge carrying County Road 650 North over Bean Creek will be replaced with a new structure on essentially the same alignment to improve traffic flow. The new structure will be a single span continuous composite girder bridge with span length of 70’. The structure will have an out-to-out length of 80' and a clear roadway width of 35'. The spill through abutments will have 2:1 sideslopes armored with limestone riprap placed over a geotextile fabric. The abutments and piers will be skewed 10° to align with the streamflow. The new approach roads will not be raised above the existing approaches. The existing structure will be completely removed. The project is partially federally funded. Plans, specifications and color photographs are enclosed in the application package.

5. Bridge - Widening (view example bridge project plan)

The superstructure of the existing 2-span bridge carrying State Road 135 over Buffalo Creek will be widened to 4 lanes to reduce traffic congestion. The 41'-6" deck will be increased by extending both the abutments and piers upstream and downstream 10'-11" thereby increasing the out-to-out width to 63'-4". The approach roads will not be raised and there will be minimal work in the channel. Color photographs and plans are enclosed in the application package.

6. Channel - Realignment or Reconstruction

Approximately 1,450' of the Ransfield Creek channel will be realigned and straightened to reduce residential flood damage. The new channel will be approximately 890' long. It will be 3' deep, with an 8' bottom width and 2:1 sideslopes. A sediment trap will be constructed at the downstream end of the new channel. The trap will be 1½' deep, 50' long and as wide as the new channel bottom. The channel will be excavated "in the dry" and will not be connected to the existing channel until the excavation has been stabilized. Material excavated from the construction of the new channel will be stockpiled for later use as fill for the old channel. If additional fill material is required it will be brought onsite from an outside source. Additionally, approximately 1,230' of existing channel immediately upstream of the realigned section will be cleared of brush and debris. Plans, specifications and color photographs are enclosed in the application package.

Both the culverts and headwalls will be skewed 12° to align with streamflow. Minor channel shaping will occur both downstream and upstream of the crossing to provide a better flow transition into and out of the culvert system. The shaping will be confined to the construction right-of-way. The shaped areas will be lined with an 18" thick layer of limestone riprap placed over a geotextile fabric. The approach roads will be constructed on fill placed to a maximum height of 5' over the existing elevations. The crown of the roadway over the culverts will be at 776.5 ft, NGVD.
