General Project Narrative:
(Description of Minimization of Water
Quality Impacts)
STV Engineers, Inc. is providing engineering services for the bridge replacement project on SR 1654 (Morton Road) over Lanes Creek. The existing bridge is a 135.3'(1 @45'2",
2@45'1") triple -span bridge with a steel plank deck on I -beams and mass concrete abutments and interior bents. The proposed structure will be a 170' long bridge with a span
arrangement of 1 @50' (21" cored slab), 1 @70' (24" cored slab) and 1 @50' (21" cored slab). The proposed roadway alignment over the bridge is the same as the existing bridge
alignment. Overall drainage patterns will be maintained. There are roadside ditches that flow towards the bridge on either side of the structure. The drainage pattern of the
ditches are being maintained and the drainage from the bridge is being discharged into the ditches. Deck drains will be needed for the proposed structure to prevent spreading
inside the travel lane. The deck drains will not discharge directly to the jurisdictional stream. Deck drains will be located over the floodplain bench area as shown in the BSR.
Impervious dikes with special stilling basins shall be used to contain the sediment laden water and prevent it from being discharged into the stream.
