SECTION 01 57 23.00 12 Page 11 material within the Bonnet Carre spillway and hauling to a stockpile site located within St John the Baptist Parish, LA on prior used agricultural lands adjacent to Hwy 61.

(b) Activity sequence. Clearing, grubbing of stockpile sites, placement of silt fence at stockpile sites, excavation from the borrow sites and stockpiling at the stockpile site.

(c) Disturbed area. Multiple borrow sites will be excavated and one sites will be cleared and used for stockpile for a total of approximatley 105 acres combined.

(d) Runoff coefficient. The runoff coeffecient will not be changed substantially over existing coeeficient at the stockpile areas. There will be no change to runoff coefficient within the Bonnet Carre Spillway.

(e) Location. The location of excavation is within the Bonnet Carre Spillway. The locations of stockpiling are as shown in the contract drawings.

(f) Associated discharges. There are no expected discharges.

(g) Name of receiving waters / wetlands / special aquatic sites.

Excavation work takes place within the Bonnet Carre Spillway.

Stockpiling work takes place within agriculutural land.

(h) Permit requirements. Permit requirements are described in the copy of Permit No. LAR050000 attached at the end of this section.

(i) Endangered or Threatened Species Concerns. Construction activities are not likely to adversely affect threatened and endangered species. There is no critical habitat for any threatened or endangered species found in proximity to the construction activity. Colonial nesting wading birds (including but not limited to herons, egrets and ibis) and bald eagles may be found in proximity to construction activity and should be avoided to reduce the risk of injuring birds.

The nesting activity period generally extends from February 15 through September 15 for wading bird and September to May for bald eagles.

Presence of nesting wading birds or nesting bald eagles must be immediately reported to Patrick Smith at (504) 862-1583. Coordination by New Orleans District personnel with the U.S Fish and Wildlife Service may result in work related restrictions depending on the species of birds found nesting and its proximity to the work site.

(j) Borrow Pits are in southern part of Bonnet Carre Spillway. The Kugler cemetery (16SC51) is east of Stockpile Contract 1 (Easting 748094, Northing 3322021). The Kenner Cemetery (16SC50) is near the east boundary of the Spillway property (Easting 746683 northing 3321781). Both sites were listed on the National Register of Historic Places as the Kenner and Kugler Cemeteries Archaeological District in 1987. The boundaries for both cemeteries have been marked with stakes. Several cultural resources investigations have been conducted throughout the Spillway and no additional historic properties are deemed eligible for the National Register of Historic Places.

Access Road to the Hwy 61 stockpile area crosses the Mississippi River Sugar Belt Railroad south of Stockpile 1. Stockpile 1 has been modified to avoid the MRSBRR. In a 6 January 2020 letter regarding the WSLP, the State Historic Preservation Office determined that the MRSBRR

SECTION 01 57 23.00 12 Page 12 is eligible for the National Register of Historic Places. However, construction of Road J will have no adverse effect on the MRSBRR.

What measures would be allowed to separate the drainage area from the Barbars Canal during high tide to mitigate the repeated flooding of Borrow Pits 1 and 2?

Government Response: Diking around the perimeter of the pits.

* There is a canal/drainage ditch within and along the west side of Borrow Pits 1 and 3 that also rises with the tides. What measures, if any, are not allowed in that area to prevent flooding during high tide?

Government Response: The contractor is responsible for water management within the borrow pits. Operations shall not impact adjacent contractors and shall not alter the drainage within the Spillway.

* Is the ditch around the Option Work stockpile part of the Base Bid or the Option Work?

Government Response: Optional Work 1.

* The access road width to the Stockpile shown on the new typical section (B3 on C-04) shows 24 feet wide with shoulders without the need for grading but the existing road is less than 24 feet in many places: is the necessary grading of the road, shoulders, and ditches to be incidental to what other items of work?

Government Response: Grading of all areas to receive surfacing is included in CLIN Item 0010, “Surfacing – OW2”, as stipulated in specification section 32 15 00.00 12.

* In Amendment 005, at Paragraph 52.236-4 PHYSICAL DATA, subparagraph (c), third sentence, it says: Only right turns into and out of the stockpile access road to and from Hwy 61 are allowed for all vehicles. Is it the intention that traffic returning to the Spillway must turn right (or west) into LaPlace to find a place to turn around?

Government Response: Yes.

* If traffic may go east on Airline, there is a partial curb island and no center turn lane on Airline Highway for trucks exiting the stockpile road turning left onto Highway 61. Is it acceptable to install lane drops and flagmen in each direction on Highway 61 to facilitate trucks entering the highway?

Government Response: No left turns will be allowed. Left turns are in violation of the approved project access permit from LaDOTD.

* Alternatively, in order to get trucks onto Airline/Hwy 61 from the stockpile access road would the installation of temporary signals be allowed?

Government Response: No.

* Will light plants and security guards be allowed at the stockpile site at night?

Government Response: Yes, provided any plan for lighting is submitted to the COR for approval.
