Polygons showing USACE Civil Works District boundaries. This dataset was digitized from the NRCS Watershed Boundary Dataset (WBD). Where districts follow administrative boundaries, such as County and State lines, National Atlas and Census datasets were used. USACE District GIS POCs also submitted data to incorporate into this dataset. This dataset has been simplified +/- 30 feet to reduce file size and speed up drawing time.

The US Army Corps of Engineers has been regulating activities in the nation's waters since 1890. Until the 1960s the primary purpose of the regulatory program was to protect navigation. Since then, as a result of laws and court decisions, the program has been broadened so that it now considers the full public interest for both the protection and utilization of water resources. These boundaries represent USACE regulatory districts. Attribute information includes an address, telephone number and url for each district. Updated AUG 2023.

The following permits are administered by the U.S. Army Corps of Engineers (ACOE). A Section 10 permit is required for all work, including structures, seaward of the mean high water line in navigable waters of the United States, defined as waters subject to the ebb and flow of the tide, as well as a few of the major rivers used to transport interstate or foreign commerce. A Section 404 permit is required for activities which involve the discharge of dredged or fill material into waters of the United States, including not only navigable waters, but also coastal waters, inland rivers, lakes, streams, and wetlands. A Section 103 permit is required to transport dredged material for the purpose of disposal in the ocean. Please note: These permits are considered together as they are administered by the U.S. Army Corps of Engineers under a single permit application. The U.S. Army Corps of Engineers, New England District has issued a Programmatic General Permit (PGP) for work in Massachusetts. The PGP provides for three levels of regulatory review: * Category I: Activities of minimal environmental impact that do not require Corps regulatory review and are classified as non-reporting. While no written notification to the Corps is required for these "minor" projects, they must comply with the conditions contained in the PGP. * Category II: Activities likely to be of minimal environmental impact but that have the potential to have adverse effects. A project-specific review and authorization from the Corps in writing are required. Copies of the Massachusetts Chapter 91 application and plans, or the Water Quality Certification application and plans, are usually sufficient for Category II review. * Category III: Activities that have potential to cause adverse environmental impacts. These projects must get an Individual Corps license, and therefore require project-specific review, are available for public review and comment, and may require preparation of an Environmental Impact Statement. Review Process: PGP, applications for projects meeting the PGP criteria must include a brief project description, vicinity map, site plan, and a plan view of the proposed structure. Federal and state resource agencies meet every three weeks to review PGP applications. A PGP is usually issued, with or without special conditions, ten days after the review closes. Individual Permits: Applications for Individual Permits must include site location, a description of the project and its purpose, and related maps and plans. Within 15 days of receiving the required application material, the Corps issues a Public Notice seeking comments from abutters, regulatory agencies and the public. Comments are accepted for up to 30 days. The Corps evaluates comments received, compliance with section 404(b)(1) of the federal Clean Water Act, public interest criteria and issues a permit. If denied, the applicant is informed of the reason(s). Neither a PGP nor an Individual Permit is valid until the applicant has obtained a 401 Water Quality Certification from DEP. Individual permits are not valid until CZM concurs that the project is consistent with state coastal policies. Applicability to Aquaculture: Shellfish culture projects smaller than one acre are generally found to be eligible for a PGP. Larger projects, such as hatcheries, may exceed the thresholds of PGP eligibility, and therefore may be required to obtain an Individual Permit. Any project in or affecting the waters of the United States must comply with the conditions of the PGP or, in the case of larger projects, the conditions of an Individual Permit.

A scope of work was developed in response to a request by the U. S. Army Corps of Engineers, Philadelphia District. The request was to perform a topographic change grid analysis for the Frankford 7.5-minute quadrangle, 1:24,000-scale topographic map, which includes the Wissinoming neighborhood, and the Germantown 7.5-minute quadrangle, which includes the Logan and Feltonville neighborhoods of the City of Philadelphia. The following tasks were performed under this scope of work: A GPS-corrected GIS grid analysis for each quadrangle was completed and is accompanied by documentation that describes procedures and provides metadata of the informational content of the GIS. A high-resolution global positioning system (GPS) survey was conducted for each topographic quadrangle in order to evaluate and correct systematic discrepancies in elevation between the modern and historic surveys. Prior to release, the fully documented GPS-corrected GIS grid analysis for each quadrangle was reviewed for (1) com-pleteness of documentation and for (2) appropriate analysis and discussion of uncertainties. The following report is in fulfillment of the tasks outlined in this scope of work and was performed by the U. S. Geological Survey for the U. S. Army Corps of Engineers, Philadelphia District under MIPR agreement number: W25PHS93358288.

This part of DS 781 presents data for bathymetric contours for several seafloor maps of the Offshore of Gaviota Map Area, California. The vector data file is included in "Contours_OffshoreGaviota.zip," which is accessible from https://doi.org/10.5066/F7TH8JWJ. These data accompany the pamphlet and map sheets of Johnson, S.Y., Dartnell, P., Cochrane, G.R., Hartwell, S.R., Golden, N.E., Kvitek, R.G., and Davenport, C.W. (S.Y. Johnson and S.A. Cochran, eds.), 2018, California State Waters Map Series—Offshore of Gaviota, California: U.S. Geological Survey Open-File Report 2018–1023, pamphlet 41 p., 9 sheets, scale 1:24,000, https://doi.org/10.3133/ofr20181023. Bathymetry contours of the Offshore of Gaviota map area in southern California was generated from acoustic-bathymetry data collected largely by the U.S. Geological Survey (USGS) and by Fugro Pelagos Inc. Acoustic mapping was completed between 2007 and 2008 using a combination of 400-kHz Reson 7125, 240-kHz Reson 8101, and 100-kHz Reson 8111 multibeam echosounders, as well as a 234-kHz SEA SWATHplus bathymetric sidescan-sonar system. In addition, bathymetric-lidar data was collected in the nearshore area by the U.S. Army Corps of Engineers (USACE) Joint Lidar Bathymetry Technical Center of Expertise in 2009 and 2010. These mapping missions combine to provide continuous bathymetric data from the shoreline to beyond the limit of California's State Waters. Bathymetric contours at 10-m intervals were generated from a modified 2-m-resolution bathymetric surface. The most continuous contour segments were preserved; smaller segments and isolated island polygons were excluded from the final output. Contours were smoothed using a polynomial approximation with exponential kernel algorithm and a tolerance value of 60 m. The contours were then clipped to the boundary of the map area.

This data reflects areas with a risk of storm tide flooding from hurricanes, based on potential storm tide heights calculated by the National Weather Service's SLOSH (Sea, Lake, and Overland Surge from Hurricanes) Model. The SLOSH Basin used for mapping was Chesapeake Bay (CP5), released in 2014. This data was prepared by the U.S. Army Corps of Engineers, Baltimore District, Planning Division in January 2016. SLOSH storm tide elevations used for this mapping are based on the Maximum of Maximums (MOM) SLOSH output dataset. The MOM output elevations represent the highest calculated storm tide values based on thousands of SLOSH simulations using different combinations of approach direction, forward speed, landfall point, astronomical tide, and intensity (Category 1 through Category 4). Categories 1 through 4 refer to the Saffir-Simpson scale of hurricane intensity. This map does not reflect the expected storm tide flooding for every hurricane, or for any one particular type of hurricane. This map shows the overall footprint of the area that has some risk of storm tide flooding from hurricanes, based on the MOM output dataset.

This map covers most of the Prudhoe Bay Oilfield on the North Slope of Alaska that was under development in 1980, covering 145 km^2. The map synthesizes work done for the US Army Corps of Engineers CRREL, the International Biome Program, and the UNESCO MAB Project 6. The mapping was based on aerial photographs taken in 1973 at a scale of 1:6000. The maps are thus a static representation of a type of arctic tundra at a time when only relatively minor terrain disturbance had occurred. It can be used as a baseline against which further natural and human-induced changes to the landscape can be measured. A geoecological approach was used in the mapping of landforms (12 units as well as linear mapping of steep embankments, undercut river banks, excavated areas and streams), soils (7 units) and land cover (29 natural vegetation units and 8 disturbed units).

Description for i03_DAU_county_cnty2018 is as follows:

Detailed Analysis Unit-(DAU) Convergence via County Boundary cnty18_1 for Cal-Fire, (See metadata for CAL-FIRE cnty18_1), State of California.

The existing DAU boundaries were aligned with cnty18_1 feature class.

Originally a collaboration by Department of Water Resources, Region Office personnel, Michael L. Serna, NRO, Jason Harbaugh - NCRO, Cynthia Moffett - SCRO and Robert Fastenau - SRO with the final merge of all data into a cohesive feature class to create i03_DAU_COUNTY_cnty24k09 alignment which has been updated to create i03_DAU_COUNTY_cnty18_1.

This version was derived from a preexisting “dau_v2_105, 27, i03_DAU_COUNTY_cnty24k09” Detailed Analysis Unit feature class's and aligned with Cal-Fire's 2018 boundary.

Manmade structures such as piers and breakers, small islands and coastal rocks have been removed from this version. Inlets waters are listed on the coast only.

These features are reachable by County\DAU. This allows the county boundaries, the DAU boundaries and the State of California Boundary to match Cal-Fire cnty18_1.

DAU Background

The first investigation of California's water resources began in 1873 when President Ulysses S. Grant commissioned an investigation by Colonel B. S. Alexander of the U.S. Army Corps of Engineers. The state followed with its own study in 1878 when the State Engineer's office was created and filled by William Hammond Hall. The concept of a statewide water development project was first raised in 1919 by Lt. Robert B. Marshall of the U.S. Geological Survey.

In 1931, State Engineer Edward Hyatt introduced a report identifying the facilities required and the economic means to accomplish a north-to-south water transfer. Called the "State Water Plan", the report took nine years to prepare. To implement the plan, the Legislature passed the Central Valley Act of 1933, which authorized the project. Due to lack of funds, the federal government took over the CVP as a public works project to provide jobs and its construction began in 1935.

In 1945, the California Legislature authorized an investigation of statewide water resources and in 1947, the California Legislature requested that an investigation be conducted of the water resources as well as present and future water needs for all hydrologic regions in the State. Accordingly, DWR and its predecessor agencies began to collect the urban and agricultural land use and water use data that serve as the basis for the computations of current and projected water uses.

The work, conducted by the Division of Water Resources (DWR’s predecessor) under the Department of Public Works, led to the publication of three important bulletins: Bulletin 1 (1951), "Water Resources of California," a collection of data on precipitation, unimpaired stream flows, flood flows and frequency, and water quality statewide; Bulletin 2 (1955), "Water Utilization and Requirements of California," estimates of water uses and forecasts of "ultimate" water needs; and Bulletin 3 (1957), "The California Water Plan," plans for full practical development of California’s water resources, both by local projects and a major State project to meet the State's ultimate needs. (See brief addendum below* “The Development of Boundaries for Hydrologic Studies for the Sacramento Valley Region”)

DWR subdivided California into study areas for planning purposes. The largest study areas are the ten hydrologic regions (HR), corresponding to the State’s major drainage basins. The next levels of delineation are the Planning Areas (PA), which in turn are composed of multiple detailed analysis units (DAU). The DAUs are often split by county boundaries, so are the smallest study areas used by DWR.

The DAU/counties are used for estimating water demand by agricultural crops and other surfaces for water resources planning. Under current guidelines, each DAU/County has multiple crop and land-use categories. Many planning studies begin at the DAU or PA level, and the results are aggregated into hydrologic regions for presentation.

Digital flood-inundation maps for a 3.4-mile reach of Fourmile Creek at Silver Grove, Kentucky, were created by the U.S. Geological Survey (USGS) in cooperation with the City of Silver Grove and the U.S. Army Corps of Engineers Louisville District. Because the City of Silver Grove is subject to flooding from Fourmile Creek and the Ohio River (backwater flooding up Fourmile Creek), a set of flood-inundation maps was created for each flooding source independently and for combinations of possible flooding scenarios. The flood-inundation maps depict estimates of the areal extent and depth of flooding corresponding to a range of different gage heights (gage height is commonly referred to as “stage,” or the water-surface elevation at a streamgage) at the USGS streamgage on Fourmile Creek at Grays Crossing at Silver Grove, Kentucky (station number 03238785), and the USGS streamgage on Fourmile Creek at Highway 8 at Silver Grove, Kentucky (station number 03238798). Near-real-time stages at these streamgages can be obtained on the internet from the USGS National Water Information System at https://waterdata.usgs.gov/. The USGS streamgage on the Ohio River at Cincinnati, Ohio (station number 03255000) is also important in this study because the National Weather Service (NWS) Advanced Hydrologic Prediction Service (AHPS), at https://water.weather.gov/ahps/, forecasts flood hydrographs for this site (NWS AHPS site CCNO1). The NWS AHPS forecast peak-stage information can be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. Flood profiles were computed for the Fourmile Creek reach by means of a one-dimensional, step-backwater hydraulic model developed by the U.S. Army Corps of Engineers. The hydraulic model was calibrated by using the current stage-discharge relation (USGS rating number 1.1) at USGS streamgage 03238785, Fourmile Creek at Grays Crossing at Silver Grove, Kentucky. The model was then used to compute water-surface profiles for 83 combinations of flood stages on the Ohio River and Fourmile Creek ranging from approximately baseflow to greater than a 2-percent annual exceedance probability event. An additional 50 water-surface profiles were computed for backwater-only flood profiles (from the Ohio River) for flood elevations (referenced to the North American Vertical Datum of 1988 [NAVD 88]) at 1-ft intervals referenced to USGS streamgage 03238798, Fourmile Creek at Highway 8 at Silver Grove, Ky., and ranged from approximately normal pool (460 ft NAVD 88) to greater than a major flood stage on the Ohio River (509 ft NAVD 88). The computed water-surface profile information was then combined with a digital elevation model derived from light detection and ranging (lidar) data to delineate the approximate areas flooded. The digital flood-inundation maps are available through the USGS Flood Inundation Mapper application (https://fim.wim.usgs.gov/fim/) that presents map libraries and provides detailed information on flood extent and depths for selected sites. The flood-inundation maps developed in this study, in conjunction with the real-time stage data from the USGS streamgages on Fourmile Creek at Silver Grove, Kentucky, and forecasted stream stages from the NWS AHPS, are intended to provide information that can help inform the public about potential flooding and provide emergency management personnel with a tool to efficiently manage emergency flood operations, such as evacuations and road closures, and assist in postflood recovery efforts. This metadata record is comprised of shapefiles of the backwater-only (from the Ohio River) flood-inundation maps. Water-surface profiles were computed for 50 backwater-only flood profiles for flood elevations at 1-ft intervals referenced to the USGS streamgage on Fourmile Creek at Highway 8 (03238798). Flood elevations ranged from approximately normal pool (460 ft NAVD 88) to greater than a major flood stage on the Ohio River (509 ft NAVD 88).

In 1995, the U.S. Geological Survey (USGS) began a series of studies to monitor several major creeks and rivers that discharge freshwater into northeastern Florida Bay and the southwest coast of Everglades National Park (ENP). These studies provide water-level, flow, salinity, and temperature data for model development and calibration and also serve as a long term data set to assist in detecting change in hydrology, as well as other physical, biological and chemical studies being conducted in these areas. These studies are being done as part of the USGS Greater Everglades Priority Ecosystems Science program (PES), which is an effort by the USGS to provide earth science information needed to resolve land-use and water issues. Additional support is provided by the U.S. Army Corps of Engineers and Everglades National Park (ENP) for PES. As part of these studies, a network of 34 hydrologic monitoring stations is already in place and historical data is currently available through the USGS South Florida Information Access (SOFIA) web page at URL: http://sofia.er.usgs.gov/. Real time information is available at the USGS National Water Information Systems URL: http://waterdata.usgs.gov/fl/nwis/rt. In 2003, CERP MAP funding through the South Florida Water Management District established 10 monitoring stations as part of the Coastal Gradients Network, Map Activity 3.1.3.3. The purpose of this MAP project with the USACE is to continue operation of these 10 stations for those MAP activities. Future funding for the northeastern Florida Bay and southwest coast estuarine studies is expected to continue from the USGS PES program in order support the larger integrated monitoring network. The MAP funding of monitoring stations within the Coastal Gradients network is a direct benefit to the overall integrated network and supplies critical hydrologic information where none previously existed.

Purpose and Scope

The purpose of this project is to operate and maintain ten (10) established hydrologic and water quality data collection platforms (DCP’s) in the coastal and fresh water marsh environments of the Everglades in order to support a larger integrated monitoring network (Fig. 1). The hydrologic and water quality information from this network is available for the development and calibration of hydrodynamic and water quality models of the Everglades, Florida Bay, and adjacent marine systems. Data will also provide information to evaluate impacts from project level CERP activity such as the C-111 Spreader Canal, the Combined Structural and Operational Plan (CSOP), and ModWaters.

The network of DCP’s collect information at points of interest along transects that represent major flow paths from the Everglades wetlands to the southern estuaries. The continuous data collected from surface and ground water along with nutrient loading computations is summarized in subsequent sections of this report. This long-term monitoring network spans the major flow paths from the Everglades wetlands to the southern estuaries which help provide a system-wide understanding of the ecosystem responses seen in the Everglades due to changes in water management practices and climatic variability. This data set contributes to the success of CERP by: a. Providing pre-CERP (baseline) and concurrent data on hydrologic and water quality parameters available for comparison during and after CERP modifications from projects such as the C-111 Spreader Canal, CSOP, and ModWaters. b. The ability to perform scientific investigations with physical data in order to increase ecosystem understanding. c. Having real-time and historic data available to detect unexpected responses within the ecosystem due to CERP activities.

These datasets were acquired from the U. S. Fish and Wildlife Service (USFWS) for use in State Programmatic General Permit (SPGP) assessment by district staff. U.S. Army Corps of Engineers permits administered by the district SPGP V-R1 On December 31, 2018, the U.S. Army Corps of Engineers (USACE) issued a revision to the State Programmatic General Permit (previously SPGP V, now SPGP V-R1) that authorizes the Florida Department of Environmental Protection, and any water management district that enters into a coordination agreement with USACE, to issue a permit on behalf of USACE for certain types of projects with relatively minor impacts to wetlands or surface waters. This authorization is limited to the following types of projects: (1) shoreline stabilization, (2) boat ramps, (3) docks, piers and other minor piling supported structures, (4) maintenance dredging of canals and channels, and (5) minor transient projects (such as marine debris removal, scientific surveys, and aquatic habitat enhancement projects). On December 19, 2018, the St. Johns River Water Management District (District) entered into a coordination agreement with USACE that allows the district to grant federal authorization on behalf of USACE under the SPGP V-R1.These data have been projected from the originating agencies specifically for geospatial analysis by SJRWMD staff for USACE State Programmatic General Permit (SPGP) V-R1 permit review. FDEP has published its own web map and feature service for SPGP review. USFWS has published many of the data they are stewards of. If for other purposes than SPGP V-R1 permit review at SJRWMD, please defer to the originating agencies for their authoritative GIS data.For additional information:https://floridadep.gov/water/submerged-lands-environmental-resources-coordination/content/federal-permits-and-coordinationhttps://www.saj.usace.army.mil/SPGP/Permitting documents for St. Johns River Water Management District (sjrwmd.com)
