PART 1: GENERAL INFORMATION

1. GENERAL:

This is a services contract to provide US Fish and Wildlife Service (USFWS) high resolution digital orthophotography, topographic and bathymetric Light Detection and Ranging (LiDAR) acquisition and processing, with topographic, planimetric, and the database development, for approximately 40 square miles including the U.S. Fish and Wildlife Service (USFWS) Bitter Lake National Wildlife Refuge (NWR) and surrounding areas, located in Roswell, Chaves County, New Mexico. The project also includes field survey for data collection of hydraulically significant infrastructure and for establishing aerial survey control with the potential for permanent control monumentation in select locations.

The LiDAR data will be processed by the Contractor to prepare a refined and detailed point cloud dataset and digital elevation model (DEM). Contracted work will generally focus on gathering topographic data to support future analyses and design for construction to repair damages to waterbird/waterfowl and threatened and endangered species (T&E) habitat from the August 2022 flood.

The Contractor should provide a written proposal outlining methods and approaches they intend or may use to meet the objectives described below.

The Government shall not exercise any supervision or control over the contract service providers performing the services herein. Such contract service providers shall be accountable solely to the Contractor who, in turn, is responsible to the Government.

1.1 Description of Services/Introduction:

The services required will include providing accurate aerial topographic and bathymetric LiDAR and imagery of Bitter Lake NWR as well as field survey. The contractor shall provide all personnel, equipment, supplies, facilities, transportation, tools, materials, supervision, and other items and non-personnel services necessary to perform the duties as defined in this Performance Work Statement (PWS) except for those items specified as government furnished property and services. The contractor shall perform to the standards in outlined in this document and follow the specifications in USGS 3DEP LiDAR Base Specifications 2022 rev. A (USGS LBS) and USGS standard for National Hydrography Dataset.

1.2 Background:

Bitter Lake NWR was established in 1937 as a refuge and breeding ground for migratory birds and other wildlife, and the protection of threatened and endangered species. It is recognized as a Globally Important Area, offering vital habitat for over 350 species of birds, including many species of shorebirds, ducks, snow geese, and lesser sandhill cranes. Bitter Lake NWR is home to 11 threatened and endangered species, with all but one is dependent on the unique hydrological features and wetland habitats. There are 3 fish species, 3 wetland plant species, a crustacean, 3 aquatic snails, and a butterfly.

Six of these federally-listed species have critical habitat designated on the refuge. In addition, the refuge has five species that are state-listed as threatened or endangered.

https://www.usgs.gov/ngp-standards-and-specifications/lidar-base-specification-online https://www.usgs.gov/ngp-standards-and-specifications/lidar-base-specification-online https://www.usgs.gov/ngp-standards-and-specifications/hydrography-standards-and-specifications

The refuge plays a crucial role in the conservation of wetlands in southwestern desert where the Chihuahuan Desert meets the Southern Plains. The refuge supports a unique hydrological mixture that includes approximately 1,200 acres of wetlands, more than 70 sinkholes, moist-soil units, riverine habitats, ciénegas, an alkaline playa lake (Bitter Lake), and fresh to brackish springs. Bitter Lake NWR is a National Natural Landmark and Research Natural Site designated by the National Park Service, and is a Ramsar International Wetland of Importance. Vegetation in the area is mainly composed of saltgrass, four-wing saltbush, alkali sacaton, creosote bush, iodine bush, salt cedar, and mesquite. Terrain is variable from flat grasslands to sloping terrain to red bluffs composed of gypsum, limestone, clay and sand.

Bitter Lake NWR consists of three tracts; the North Tract north of highway US 70 is 12,269 acres, Middle Tract is 11,279 acres, and the South Tract is 1,186 acres. The North Tract contains the Salt Creek Wilderness Area, the Middle Tract is where the refuge Visitor Center, auto tour loop and wetland units are located, and the South Tract is the refuge farmland with the capability of flood irrigation with 3 wells. The project area will include all three tracts, as shown on Attachment 1.

In August 2022, a large flood event occurred on the Pecos River where 8-11” of rain fell in northern Chaves County then flowed into the Pecos River basin. USGS gage 08386000 on the Pecos River near Acme, NM along the US 70 bridge showed a peak river height of 17.4 feet. Bank height is 10 feet and flood stage is 13 feet. Spatial analysis provided by National Weather Service indicated that the widest extent of the flooding was at least 1.74 miles wide, which occurred on Bitter Lake NWR and Bureau of Land Management (BLM) Overflow Wetlands to the south of Acme, NM.

During the normal low flow timeframe in the summer, the Pecos River typically flows at 40 cubic feet per second (cfs). Seasonal block releases on the Pecos River move 1,000 cfs of water from Sumner Dam to Brantley Dam and down through Texas. During the August 2022 flood event, the Pecos River flow was estimated to be over 20,000 cfs.

The flood caused damage to refuge wetland units and infrastructure, scouring approximately 28 miles of wetland levees, roads, and firebreaks; and damaging water control structures and a submersible pump.

The levees range from 40- to 100-foot-wide bases to 20- to 30-foot-wide tops.

The LiDAR collection must be completed in November 2026 – February 2027 with the actual flight time selected by the Refuge based on site conditions. Areas of significance include Bitter Creek which is impacted by algae growth and regularly covered with tumbleweeds. As these will impact the bathymetric LiDAR collection, the Refuge will clear Bitter Creek prior to collection. The flight must occur within two weeks of clearing to limit the impacts of vegetation. Aerial LiDAR acquisition will occur with close coordination between the Contractor, Project Manager, and Refuge Point of Contact.

• Rain, snow, fog, smoke or similar environmental conditions shall be avoided.

• Project AOI(s) shall be fully and sufficiently covered with no data voids or data holidays (i.e. gaps between flightlines).

No points shall be deleted from the LAS file and classification codes will follow the ASPRS Standard LiDAR Point Classes conforming to the USGS LBS minimum data classification scheme standard with U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX) classes for bathymetry:

1 Processed, but unclassified 2 Bare earth ground 3 Low vegetation 4 Medium vegetation 5 High vegetation

6 Buildings, other man-made structures 7 Low noise (low or high; manually identified, if necessary) 9 Water (topographic sensor)

17 Bridge deck 18 Water (topographic sensor) 20 High noise (high manually identified, if necessary) 21 Ignored ground (typically breakline proximity) 22 Snow (if present and identifiable) 40 Bathymetric Point, Submerged Topography (e.g., seafloor or riverbed)

Water Surface (sea/river/lake surface from bathymetric or topographic-bathymetric lidar; distinct from Point Class 9, which is used in topographic-only lidar and only designates “water,” not “water surface”)

Derived water surface (synthetic water surface location used in computing refraction at water surface)

Submerged object, not otherwise specified (e.g., wreck, rock, submerged piling)

44 IHO S-57 object, not otherwise specified

No-bottom-found (bathymetric lidar point for which no detectable bottom return was received)

64 Submerged Aquatic Vegetation

Denotes bathymetric bottom temporal changes from varying lifts, not utilized in bathymetric point class

• Special attention must be applied to the classification process due to the geographic nature of the project area. Dense vegetation data voids must also be minimized by the automatic removal process and “over smoothing” due to aggressive classification must be avoided.

• The collection plan should be made to minimize voids in bathymetric LiDAR.
