LPV-02.1 - Reach 3 Lakefront Levee (3rd Lift)- Phase 1
Levee - Bring to authorized level of protection

This segment of the HPS consists of approximately 2.3 miles along the East Jefferson lakefront from the east end of the tie-in floodwall on the east side of Pump Station #3 (Suburban) to the west end of the tie-in floodwall on the west side of the Pump Station #2 (Elmwood). This earthen levee has a 7 foot wide crown with a design elevation of +16 NAVD88 and 1 vertical on 3 horizontal side slopes. At present the crown of this levee reach is approximately 1 foot below design grade on average. This contract provides for accelerated construction completion to the authorized level of protection of a levee lift to an elevation of +17 NAVD88, thus providing one foot of overbuild in anticipation of further levee subsidence.
