Ecological Suitability of the Site 3.1

Historical Site Conditions

The Mangrove Bayou Coastal Marsh Mitigation Bank, located within the Cameron-Creole Watershed, consisted, historically, of densely vegetated brackish marsh as evidenced by aerial photography. In 2005 these marshes suffered severe impacts due to Hurricane Rita and again in 2008 due to Hurricane Ike. In addition to impacts from hurricanes and as a result of damage due to hurricanes, the project area has been affected by surface erosion and the exportation of organic matter as well as compaction of soils due to loss of vegetation and root material resulting in decreases in elevation. Prior to Hurricane Katrina, mean elevation within the project area was found to be 0.784, as determined by available LIDAR data. Following Hurricanes Katrina and Ike, in 2009, mean elevation was determined to be -0.090, based upon contour data provided by the United States Department of Agriculture Natural Resources Conservation Service within the 2

Cameron-Creole Freshwater Introduction Project (CS-49) Vegetative Plantings Preliminary Design Report dated September 2009. Although much of this change in elevation is due to impacts associated with these two hurricanes, surface erosion, exportation of organic matter, and subsidence are actively occurring within this area. Prior to 2005, mean salinity within the project area was determined to be 8 ppt. Due to storm surge, severe and persistent flooding within the project area occurred following Hurricane Rita and continued through the beginning of 2006. Once storm waters receded, it became apparent that a large portion of the marsh located within the project area had fragmented and many areas had become mudflats with little to no vegetation. Again in September of 2008, due to Hurricane Ike, the marsh located within the project area sustained additional damage resulting in additional loss of marsh and vegetation within the project area. In addition, salinities had risen significantly to a mean of 11 ppt. following the storm and receding of storm waters. By June of 2012, salinities were documented to be between 14-17 ppt. and water levels were found to be 0.2 feet. Within only a few months of very low regional rainfall and scheduled monthly openings of the control structures within the Cameron-Creole Watershed, it was documented that salinities had increased up to 21 ppt. and the water level had risen up to +1 foot at which it remained throughout the remainder of 2012.

3.2

Current Site Conditions and Characteristics

The majority of the project area, approximately 101.58 acres, is now shallow open water which contains little to no living vegetation. The remaining 35.17 acres consists of fragmented emergent brackish marsh. As of June of 2014, as noted within the United States Department of Agriculture Natural Resources Conservation Service Trip Report via Email, water levels within the project area were documented to be 0.4 feet and salinities were found to be 18-20 ppt. Subsidence rates within this area are 1-15 mm/year as documented within Louisiana's Comprehensive Master Plan for a Sustainable Coast. CURRENT VEGETATION Vegetation is present within the approximately 35.17 acres of emergent brackish marsh located within the project site. Vegetation located within the emergent brackish marsh consists entirely of Spartina alterniflora and Spartina patens. No vegetation is present within the approximately 101.58 acres of shallow open water. CURRENT SOILS The project site, in its entirety, is mapped as Bancker muck according to the current USDA NRCS Custom Soil Resources Report for Cameron Parish, Louisiana (Figure 3). Bancker muck, typical of Cameron Parish, Louisiana, consists of very poorly drained, very slowly permeable, slightly saline, mucky mineral soils located within brackish marshes. These soils are generally flooded with several inches of water; however, these soils may be flooded with up to 10 feet of water during intense storms due to extreme tides. This soil is listed as hydric within the National 3

Lists of Hydric Soils; All States (U.S. Department of Agriculture Natural Resources Conservation Service, 2014). PROPERTY CONSTRAINTS Mangrove Bayou Coastal Marsh Mitigation Bank project site is located South of Grand Lake within an area of land known as "The Island" within Calcasieu Parish, Louisiana. The project site and adjacent property are located within unincorporated land, absent of zoning regulations. The site is connected to and surrounded by both natural and man-made tributaries and emergent brackish marsh. JURISDICTIONAL DETERMINATION A Jurisdictional Determination was issued by CEMVN on September 26, 2014, stating that the Mangrove Bayou Coastal Marsh Mitigation Bank project site, in its entirety, is a wetland and subject to U.S. Army Corps. Of Engineers jurisdiction. A copy of the Jurisdictional Determination is included within Appendix A.

3.3

General Watershed Characteristics

WATER SOURCES AND LOSSES The primary sources of water for the Mangrove Bayou Coastal Marsh Mitigation Bank are precipitation, flow from adjacent properties due to tidal influence, or ingress from Calcasieu Lake due to management of the Cameron-Creole Watershed through the use of water control structures. Average annual precipitation within the vicinity of the project area is approximately 57 inches per year. June is the wettest month of 2014 with average precipitation of 14.54 inches, while April is the driest month of 2014 with average precipitation of 0.85 inches. Water levels within the Mangrove Bayou Coastal Marsh Mitigation Bank project area are somewhat tidally influenced from Calcasieu Lake; however, water levels within this area are managed through the use of the water control structures located along the eastern shore of Calcasieu Lake. During high water events, water flows into the Mangrove Bayou Coastal Marsh Mitigation Bank project area from the levee borrow canal bordering the western side of the project area, from Lake Shore Canal bordering the northern side of the project area, from the PPG Ditch to the east, and from the marsh bordering the southern portion of the project area. Water from within the project area then drains back through all of those areas at varying water levels. By implementing the hydrologic restoration plan as detailed within Section 4.1, the project area elevation will be increased such that ponding within the area will be decreased allowing for growth of emergent vegetation. Drainage will then occur from west to east such that water drains exclusively through gaps within the containment placed along PPG ditch and through adjacent marsh located south of the project area (Figure 5).

HYDROPERIOD The presence of hydric soils indicates that prolonged conditions of saturation and/or inundation have occurred historically within the area. This site is composed entirely of Bancker muck, a hydric soil, which consists of very poorly drained, very slowly permeable, slightly saline, mucky mineral soils. Bancker muck is located within brackish marsh and is generally flooded with several inches of water; however, these soils may be flooded with up to 10 feet of water during intense storms due to extreme tides. During periods when Bancker muck is not flooded, the water table exists 1.0 foot above to 0.5 foot below the surface.

3.4

Congruence with Local Action Plans

The Mangrove Bayou Coastal Marsh Mitigation Bank is in line with the goals and objectives of the Cameron-Creole Watershed Management Plan that was developed to assist in restoring the Cameron-Creole Watershed to the approximate 1972 conditions by restoring the vegetative communities and salinity regimes within the watershed. CWPPRA project CS-49 is located within the vicinity of the project area. CS-49, otherwise known as the Cameron-Creole Freshwater Introduction, will introduce freshwater to restore the function, value, and sustainability of approximately 22,247 acres of marsh and open water within the Cameron-Creole Watershed. A portion of CS-49, the vegetative planting portion, was completed within the Mangrove Bayou Coastal Marsh Mitigation Bank project area in June of 2012; however, all vegetation planted within the project area has since died and the United States Department of Agriculture Natural Resources Conservation Service has recommended, as of July 2014 within a Trip Report via Email (Appendix B), that no additional plantings occur within this area at this time. Instead, it is suggested that there are numerous marsh nourishment projects needed within this area which would result in increases in elevation thereby providing conditions more conducive to supporting vegetation. Therefore, creation of the Mangrove Bayou Coastal Marsh Mitigation Bank will restore an area that was intended to be restored within CS-49, making this project in line with the goals and objectives set forth by CWPPRA for this area. Southwest Coastal Louisiana Feasibility Study project 3c1 is also located within the vicinity of the project area. 3c1 includes beneficial use of dredge material, obtained from the Calcasieu Ship Channel, to restore approximately 1,765 acres of brackish marsh located adjacent to the eastern rim of Calcasieu Lake within the Cameron-Creole Watershed. The Mangrove Bayou Coastal Marsh Mitigation Bank does fall within the proposed marsh restoration area and is in line with the proposed project as beneficial use of dredge material would be used to restore marsh.

3.5

General Bank Need

There are currently no brackish marsh mitigation banks located within the proposed primary service area of the Mangrove Bayou Coastal Marsh Mitigation Bank, the Chenier Plain including HUC 08080206, HUC 08080202, and a portion of HUC 08080103. The Mangrove Bayou Coastal Marsh Mitigation Bank will provide mitigation for oil and gas exploration and production, as well as industrial development which is currently ongoing within 5

this area of the state. In addition, mitigation will be available for residential and commercial development.

3.6

Technical Feasibility

The Mangrove Bayou Coastal Marsh Mitigation Bank has a high degree of technical feasibility. The project is located within the Cameron Creole Watershed, an area that is extensively studied and, once again, extensively controlled for fisheries, vegetative communities, and salinity regimes. This degraded/fragmented/deteriorated brackish marsh, the project site, is surrounded by areas of existing emergent brackish marsh at elevations conducive to support and that do support emergent brackish marsh. It is expected, due to the increased elevation of the marsh and the salt tolerant species (0-30 ppt.) to be planted, that the success of the project will not be completely dependent upon strict adherence to the Cameron-Creole Watershed Management Plan, although strict adherence would be preferred. Periodic fluctuations in water level and salinity are to be expected and were considered during preliminary design and engineering. The Mangrove Bayou Coastal Marsh Mitigation Bank shall be a success once elevations within the project site are increased, hydrology is altered such that shallow open water is not located on site year round, and salinities are lowered. In addition, the CWPPRA project, the Cameron-Creole Freshwater Introduction Project (CS-49), once complete, will provide for additional freshwater input which will assist in sustainability and increases in organic productivity within this area.

Bank Establishment 4.1

Management Summary

HYDROLOGIC RESTORATION The primary sources of hydrology of the proposed Mangrove Bayou Coastal Marsh Mitigation Bank include rainfall; groundwater; and surface inundation due to flooding events, tidal fluctuations, or opening and closing of water controls structures associated with the CameronCreole Watershed Management Plan. Rainfall is estimated to be approximately 57 inches per year according to National Oceanic and Atmospheric Administration National Weather Service Weather Forecast Office. Water levels, from the Cameron-Creole Watershed Management Plan, are expected to remain between 2" above and 6" below marsh elevation; however, within the project area, mean high water is 0.7506 and mean low water is -0.0276. In order to create marsh and enhance existing marsh within the project area, containment will be constructed along the borrow canal and PPG Ditch. Dredge material, approximately 321,420 cubic yards, will then be placed within the containment at a post construction target elevation of +1.5' NAVD 88 elevation over the entirety of the project area designated for marsh creation. In order to enhance existing marsh, dredge material will be placed within the degraded areas within the project area designated for marsh creation at a post construction target elevation of +1.5'NAVD 88. Based upon expected settlement rates for this area, marsh elevation is expected 6

to stabilize within the MHW and MLW levels. Following dewatering, containment along PPG Ditch will be gapped in order to allow for drainage of the project area. Drainage will also occur through the southern end of the project area as containment will not be constructed within this area. Figures 6 and 7 present typical cross-sections for creation and enhancement construction activities. DRAINAGE AREA Once the Mangrove Bayou Coastal Marsh Mitigation Bank project is completed, water will enter the project area via rain water accumulation, from the south via sheet flow through marsh bordering the southern portion of the project area, and through gaps located within the containment along PPG Ditch. Water will then drain into PPG Ditch through those same gap and through the marsh located south of the project area. VEGETATIVE RESTORATION Vegetation restoration will include planting Spartina alterniflora and Spartina patens within the approximately 101.58 acres of created emergent brackish marsh and where necessary within the approximately 35.17 acres of enhanced emergent brackish marsh. Spartina alterniflora can tolerate water with salinities ranging from 0 ppt. to 35 ppt. Spartina patens will tolerate irregular inundations of water with a salinity of 0 ppt. to 35 ppt. INVASIVE SPECIES CONTROL During both short-term and long-term success monitoring, invasive plant species growing within the planted areas will be treated using herbicidal treatment, if necessary. MONITORING Monitoring shall begin 30 to 60 days after completion of placement of dredge material and shall then occur during active growing season of years 1, 3, and 7. Monitoring reports shall be prepared following monitoring activities and reports shall be submitted by no later than December 31 of that monitoring year. If additional dredge material is required in order to meet elevation requirements, then required monitoring shall be based on the new dredge material completion date. If additional plantings are required, then required monitoring shall be based on the new planting completion date.

4.2

Proposed Service Area

The Mangrove Bayou Coastal Marsh Mitigation Bank is located in the Lower Calcasieu Watershed, HUC 08080206. Miami Corporation proposes the Chenier Plain including HUC 08080206, HUC 08080202, and a portion of HUC 08080103 as the Primary Service Area of the Mangrove Bayou Coastal Marsh Mitigation Bank.
