This surface provides the topo data of the embankment as well as intake and discharge canals Surfaces:

IP-1 Lake N Coffer Dam.dtm:

Designed lakeside earthen cofferdam plug. This is built on existing grade (“13-078_USACE.dtm”) to elev. 22.0’ to 23.0’, top width of 10’ with 1:3 lakeside slopes and 1:3 landside slopes.

IP-1 Lake S Coffer Dam.dtm Designed lakeside earthen cofferdam plug. This is built on existing grade (“13-078_USACE.dtm”) to elev. 22.0’ to 23.0’, top width of 10’ with 1:3 lakeside slopes and 1:3 landside slopes.

IP-1 Land Coffer Dam.dtm This is to be used as an access road around construction site. It has a width of 12’ along the ramps and a bottom with of 16’ to accommodate temporary concrete barriers. 1:3 side slopes interior and exterior.

1on3 Excavation with Ramp1on4.dtm:

This surface design excavates the existing Herbert Hoover embankment surface to elevation 2.2 using 1:3 side slopes. This will allow the removal of existing Culvert IP-1 structures and barrels and replace with new. Modeled to intersect “13-078_USACE.dtm” This surface also provides two ramps with 1:4 slopes 16’ wide allowing access into and out of excavated pit. Adjacent to the landside driven pile cofferdam and within the area of excavation there is a bench elevation of 5.0 and bench width of 10’. The side slope begins at 1:4 intersecting the excavation surface or elevation of 2.2, and then slope is steepened to 1:2 after dewatering is completed.

IP-1 Restoration.dtm:

Designed to restore the excavated Herbert Hoover embankment after the construction of new S-292 structure. Crest Width is 16’ wide (12’ Lime rock, 2’ sod each side of lime rock) approaching the structure and 49’ wide at the structure (45’ Lime rock, 2’ sod each side of lime rock). Embankments having a maximum slope of 1V:4H.

IP-1 Lake Channel.dtm:

Lakeside approach channel at the finished grade or the top of riprap. 9’ wide elevation at structure 6.5 out to match existing.

IP-1 Land Channel.dtm:

Landside approach channel at the finished grade or the top of riprap. 9’ wide elevation at structure. Elevation 6.5 at structure sloping to match existing.
