Protecting People, Property and Our Way of Life

Valentine-East

The boundary is the area enclosed by a polygon beginning at the intersection of the Bayou Lafourche and Company Canal in Lockport. The boundary continues generally north and east along the Company Canal to the intersection of the Company Canal and the Lafourche Parish Line in Lake Salvador. The boundary then continues east along the Lafourche Parish line to the intersection of the Lafourche Parish Line with the GIWW. The boundary then runs along the north bank of the GIWW generally to the west and south to the intersection of the GIWW and Bayou Lafourche in Larose. The boundary then meanders up the east bank of Bayou Lafourche to the point of beginning at the intersection of the Company Canal and Bayou Lafourche in Lockport. The 2010 Census shows a population of 2,389 in this Project Area which represents a 12% increase in population over the last 20 years with a 6% increase in the last 10 years.

 

Backwater Flood Protection Levees:  This broadly defined project would include making improvements to various existing backwater flood protection levees within the project area.  This broadly scoped project is assigned the following COA and estimated funding is primarily for overall development of projects

Project COA 6800.50Z, Estimated Cost: $100,000.00

            Targeted areas include the following:

McLeod Pump District: This 450 acre forced drainage system along LA Highway308 east of Lockport protects 30 residences, a future school site and other infrastructure. The system has no traditional levees being isolated from adjacent drainage areas by the old railroad embankment, a road bed that parallels the Company Canal to the north and a headland road to the south.  Forced drainage of the area is accomplished with a single pump station with 1-24” diesel fueled, engine driven pump and 1-20” electric motor driven pump. Overall, the ring “levees” are adequate in elevation except for portions of the northern border. Proposed improvements would include re-capping and re-shaping the entire northern border, clearing and widening an internal drainage channel / culverts, and making improvements to the existing pump station.

Project COA 6800.52Z, Estimated Cost: $1,052,000.00

            Old Valentine Pump District: This 6,186 acre forced drainage system along LA Highway308 west of Lockport protects 201 residences, several businesses and other infrastructure. The system has approximately 29,000 feet of ring levees providing backwater flooding protection.  Forced drainage of the area is accomplished with a single pump station with 3-48” diesel fueled, engine driven pump and 1-24” electric motor driven pump. Overall, the ring levees are insufficient in height and profile. Hurricane Isaac did not top the levee system; but, it was threatened in several locations. The levee adjacent to the collection canal has culverts through it which limit its ability to serve as a backwater flood protection levee.  This can be rectified by changing the alignment of the existing levees to exclude the oxidation bond areas (re-routing its drainage), using and improving portions of the Giosha Ridge as part of the boundary and making improvements along the existing levee as well as adding / enhancing additional levee sections. Proposed improvements would include re-capping and re-shaping the entire ring levee as described above, clearing and widening an internal drainage channel / culverts, and making improvements to the existing pump station. An additional new pump station at the northern end of the system is proposed and already funded. (See COA 6800.61Z below)

Project COA 6800.53Z, Estimated Cost: $2,050,000.00

            Humble Pump District: This 867 acre forced drainage system along LA Highway308 west of Lockport protects 1 residence, and other infrastructure. The system has no traditional levees being isolated from adjacent drainage areas by a remnant ridge, and a road bed / berm the north and south.  Forced drainage of the area is accomplished with a single pump station with 1-36” diesel fueled, engine driven pump. Overall, the ring “levees” are adequate in elevation except for portions of the northern border. Proposed improvements would include re-capping and re-shaping the entire northern border, clearing and widening an internal drainage channel, and making improvements to the existing pump station.

Project COA 6800.54Z, Estimated Cost: $1,257,000.00

            New Valentine / Ludevine Pump District: This 2,523 acre forced drainage system along LA Highway308 west of Lockport protects 25 residences, and other infrastructure. The system has approximately 24,900 feet of ring levees providing backwater flooding protection. Forced drainage of the area is accomplished with two pump stations. The New Valentine Pump station has 1 – 36” diesel fueled engine driven pump. The Ludevine Pump Station has 1-24” and 1 – 36” diesel fueled, engine driven pump. Overall, the ring levees are insufficient in height and profile with multiple encroachments and many trees and roots in the levees.  Hurricane Isaac topped the levee system in multiple locations and threatened in additional locations. Re-capping and re-shaping the entire levee system is part of the Valentine East – Lockport to Larose Levee Project (See COA 6800.51Z below) and is not part of this project scope. Proposed improvements would include clearing and widening an internal drainage channel, and making improvements to the existing pump stations.

Project COA 6800.55Z, Estimated Cost: $2,412,000.00

            T-Bois Pump District: This 736 acre forced drainage system along LA Highway308 east of Larose protects 351 residences, multiple businesses and other infrastructure. The system has approximately 6,130 feet of ring levees providing backwater flooding protection. Forced drainage of the area is accomplished with one pump station with 3 – 36” diesel fueled engine driven pumps. Overall, the ring levees are insufficient in height and profile with multiple encroachments and many trees and roots in the levees.  Hurricane Isaac did not top the levee system; but was threatened  in multiple locations. Re-capping and re-shaping the entire levee system is part of the Valentine East – Lockport to Larose Levee Project (See COA 6800.51Z below) and is not part of this project scope. Proposed improvements would include clearing and widening an internal drainage channel / culvert, and making improvements to the existing pump stations.

Project COA 6800.56Z, Estimated Cost: $1,457,000.00

            Rita Pump District: This 63 acre forced drainage system along LA Highway308 east of Lockport protects 100 residences, several businesses and other infrastructure. The system has approximately 1,950 feet of levees providing backwater flooding protection. Forced drainage of the area is accomplished with a single pump station with 1-20” diesel fueled, engine driven pump and 1-12” electric motor driven pump. Overall, the levees are insufficient in height and profile. Hurricane Isaac did not top the levee system; but, it was threatened in several locations. Proposed improvements would include re-capping and re-shaping the entire levee and making improvements to the existing pump station. The NLLD has engaged an engineer (Leonard Chauvin, Inc.) to provide some survey work to address some internal drainage issues and the current levee heights. A project has been framed up which involves clearing the levee banks and in-house resources to establish an improved levee along the south bank of the Company Canal.

Valentine East Lockport to Larose Levee Project:  In the very early stages of development, this project would be similar to our west side Lockport to Larose Levee Project. The project would re-construct the existing drainage levees from Lockport to Larose into storm protection levees simultaneously improving internal drainage for the entire project area. We recently received an appropriation of $300K from State Capital Outlay to begin some planning for this project. However, that appropriation was not converted to a cash line of credit. The NLLD is working to assign this project to an Engineer for project design, development and permitting.

Industrial Ave. Floodwall: This project involves building a floodwall along Industrial Ave. north of Larose along the GIWW. The project intent is to prevent storm water in the GIWW from encroaching into adjacent neighborhoods. Currently LPG is seeking funds for this project and the NLLD remains in a technical support roll.

Company Canal Pump Station: Currently, the Lafourche Parish Government has received State funding to complete a new Pump Station that will take water from the 40 Arpent canal east of Bayou Lafourche, south of Lockport and discharge into the Company Canal on the Northern end of the Old Valentine Pump District (see above). Additional funding from Lafourche Parish Drainage District #1 as well as an NLLD contribution of nearly $1,000,000.00 of cash and in-kind services will be provided for this project. (See Company Canal Project COA 6700.51Z in Gheens PA.)  NLLD remains in a technical support roll for this project.

Project COA 6800.61Z, Estimated Cost: $100,000.00

 

Bayou Lafourche Closure: This project would include installing a storm water prevention deployable closure in Bayou Lafourche at a future determined location near the Freshwater District intake in Lockport. The closure would prevent salt water from backing into Bayou Lafourche circumventing backwater levees. This project may are may not include involvement with a similar structure planned by the Parish to prevent salt water intrusion.
