This app displays a series of general information for an address, location, or where the user clicks in DC. Some information returned are:Municipal Separate Storm Sewer System (MS4) areaCombined Sewer System (CSS) areaWatershed, Subwatershed, HUC12, HUC14, HUC16Ward, ANC, SMD, and the address of the locationCensus Tract and zip code For addresses along the borders of watersheds and sewer areas, further investigation should be taken. For hydrologic calculations and determinations, the USGS Watershed Boundary Dataset (WBD) should be referenced.DC Water operates a "separate" (MS4) and "combined" (CSS) sewers. Since the early 1900's, sewers constructed within the District have been separate systems and no new combined sewer systems have been built. These two independent piping systems: CSS mixes "sanitary" (sewage from homes and businesses) with stormwater while the MS4 is for "stormwater" only. In the District, approximately two thirds of the District is served by the MS4. The remaining one-third is served by the CSS.Areas highlighted in blue are MS4, in orange are CSS, and in green are direct drain areas that drain directly to streams and rivers.The MS4 system discharges into portions of the Potomac, Anacostia and Rock Creek drainage areas. The CSS drains to Blue Plains Advance Wastewater Treatment Facility.Visit DOEE - Water in the District Page or DOEE Environmental Mapping.For the USGS Hydrologic and Watershed Boundary Data for DC, visit this Link.https://dcgis.maps.arcgis.com/home/item.html?id=54da82ed8d264bbbb7f9087df8c947c3

Link to AMAFCA site with stormwater maps and data features are available, including shapefiles and interactive maps.

This layer contains the stormwater system for Lawrence, Kansas, excluding assets for the University of Kansas and Haskell Indian Nations University. It provides essential details such as material, diameter, and condition, enabling municipalities to monitor the integrity of the stormwater network. Data is updated continuously.Stormwater Pipes: This segment of the infrastructure layer provides data on the extensive network of pipes that transport stormwater runoff. Information such as pipe diameter, material composition, installation date, and maintenance history is recorded. GIS mapping allows authorities to visualize the spatial distribution of pipes, facilitating effective monitoring and maintenance planning.Catch Basins: Catch basins, also known as storm drains, are vital components of the stormwater system. GIS technology precisely maps the location of catch basins and includes attributes such as size, condition, and connectivity to the pipe network. This data aids in identifying critical points in the system where debris often accumulates, potentially causing blockages and localized flooding.Culverts: Culverts are structures that allow water to flow under roads, railways, or embankments. GIS mapping of culverts includes parameters like dimensions, material type, and flow capacity. This information helps in assessing the structural integrity of culverts and ensures that they can handle stormwater flow during heavy rain events.Retention/Detention Basins: GIS technology identifies the locations of retention and detention basins, which are designed to temporarily hold stormwater and release it slowly. Attributes such as size, depth, and drainage area are recorded. This data is essential for managing the storage and controlled release of stormwater, preventing downstream flooding and erosion.

This service represents CTDOT’s Stormwater Drainage Network. The data is collected from a collection of resources including completed construction plans, right-of-way plans, permits & field reconnaissance. Not all drainage features depicted on the map accurately reflect the condition of the drainage network that is currently built. Data is updated, modified and added daily by CTDOT to both grow the inventory of drainage structures statewide and to improve accuracy. Drainage data is collected for continued compliance of the CTDOT MS4 Permit and for CTDOT’s Asset Management Purposes.Please refer to the CTDOT Maintenance Guide for definitions of all Drainage Features:ctdot-ms4-gis-database-maintenance-guide-jan-2021.pdf

The Los Angeles County Storm Drain System shows drains, channels, catch basins, and debris basins in the County of Los Angeles using a web-based map viewer. It currently includes facilities owned and maintained by the Los Angeles County Flood Control District (District), the City of Los Angeles, and United States Army Corps of Engineers (Corps). Information on the facilities, such as date built, size, and material can be obtained by selecting them. The plans are also available for the Corps and District facilities.

These maps represent conceptual master storm drainage plans for various areas of the County. They were created as a tool to exact fees from properties within each area that would be deposited into independent Drainage Trust Funds with the purpose of eventually having sufficient funds to build storm drainage facilities. All of these Drainage Trust Fund areas except the following have been eliminated:

• Lockeford
• Escalon
• Manteca
• Woodbridge

Per Frank Sousa (Winter 2009), he would prefer to call this layer "drainage network" because it includes streets flow which may not be considered a watercourse. Started in 1999 it covered the municipal planning area, done in pieces startings with the core of the City. Was densified to make sure there was a line where there was 100 cfs flow or more for regulatory purposes. Streets flow mapping is incomplete. 7/10/2010 - loaded shapefile into EDITSDE geodatabase from Stormwater shapes folder. circa 1999 - Shapefile create by Frank Sousa in City of Tucson Stormwater from aerial photos, topography and ground knowledge.

This pipe feature class represents current wastewater information of the mainline sewer in the City of Los Angeles. The Mapping and Land Records Division of the Bureau of Engineering, Department of Public Works provides the most rigorous geographic information of the storm drain system using a geometric network model, to ensure that its storm drains reflect current ground conditions. The conduits and inlets represent the storm drain infrastructure in the City of Los Angeles. Storm drain information is available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works.Associated information about the wastewater Pipe is entered into attributes. Principal attributes include:PIPE_SUBTYPE: pipe subtype is the principal field that describes various types of lines as either Airline, Force Main, Gravity, Siphon, or Special Lateral.For a complete list of attribute values, please refer to (TBA Wastewater data dictionary). Wastewater pipe lines layer was created in geographical information systems (GIS) software to display the location of sewer pipes. The pipe lines layer is a feature class in the LACityWastewaterData.gdb Geodatabase dataset. The layer consists of spatial data as a line feature class and attribute data for the features. The lines are entered manually based on wastewater sewer maps and BOE standard plans, and information about the lines is entered into attributes. The pipe lines are the main sewers constructed within the public right-of-way in the City of Los Angeles. The ends of line segments, of the pipe lines data, are coincident with the wastewater connectivity nodes, cleanout nodes, non-structures, and physical structures points data. Refer to those layers for more information. The wastewater pipe lines are inherited from a sewer spatial database originally created by the City's Wastewater program. The database was known as SIMMS, Sewer Inventory and Maintenance Management System. For the historical information of the wastewater pipe lines layer, refer to the metadata nested under the sections Data Quality Information, Lineage, Process Step section. Pipe information should only be added to the Wastewater Pipes layer if documentation exists, such as a wastewater map approved by the City Engineer. Sewers plans and specifications proposed under private development are reviewed and approved by Bureau of Engineering. The Department of Public Works, Bureau of Engineering's, Brown Book (current as of 2010) outlines standard specifications for public works construction. For more information on sewer materials and structures, look at the Bureau of Engineering Manual, Part F, Sewer Design, F 400 Sewer Materials and Structures section, and a copy can be viewed at http://eng.lacity.org/techdocs/sewer-ma/f400.pdf.List of Fields:STREET: This is the street name and street suffix on which the pipe is located.PIPE_LABEL: This attribute identifies the arc segment between two nodes, which represents the pipe segment.

River hydraulic geometry is an important input to hydraulic and hydrologic models that route flow along streams, determine the relationship between stage and discharge, and map the potential for flood inundation give the flow in a stream reach. Traditional approaches to quantify river geometry have involved river cross-sections, such as are required for input to the HEC-RAS model. Extending such cross-section based models to large scales has proven complex, and, in this presentation, an alternative approach, the Height Above Nearest Drainage, or HAND, is described. As we have implemented it, HAND uses multi-directional flow directions derived from a digital elevation model (DEM) using the Dinifinity method in TauDEM software (http://hydrology.usu.edu/taudem) to determine the height of each grid cell above the nearest stream along the flow path from that cell to the stream. With this information, and the depth of flow in the stream, the potential for and depth of flood inundation can be determined. Furthermore, by dividing streams into reaches or segments, the area draining to each reach can be isolated and a series of threshold depths applied to the grid of HAND values in that isolated reach catchment, to determine inundation volume, surface area and wetted bed area. Dividing these by length yields reach average cross section area, width, and wetted perimeter. Together with slope (also determined from the DEM) and roughness (Manning's n) these provide all the inputs needed for establishing a Manning's equation uniform flow assumption stage-discharge rating curve and for mapping potential inundation from discharge. This presentation will describe the application of this approach across the continental US in conjunction with NOAA’s National Water Model for prediction of stage and flood inundation potential in each of the 2.7 million reaches of the National Hydrography Plus (NHDPlus) dataset, the vast majority of which are ungauged. The continental US scale application has been enabled through the use of high performance parallel computing at the National Center for Supercomputing Applications (NCSA) and the CyberGIS Center at the University of Illinois.

Licensed agricultural tile drainage contractors create plans for numerous agricultural tile drainage systems and install thousands of feet of agricultural drainage tile each year. As a requirement of their license, each contractor must report to the Ontario Ministry of Agriculture, Food, and Rural Affairs (OMAFRA) the location of the area where they installed drainage tile. These areas are represented as polygon features.Legislated or Legal Authority for Collection: Agricultural Tile Drainage Installation Act (Regulation 18)Additional Time Period Information: The legislation was official as of 1983 but some the data holding may contain data that was installed prior to 1983. The legislation is still in effect therefore the data holding is still currently receiving information.Additional Metadata Location: Ontario Ministry of Agriculture and Food, Ontario Ministry of Rural Affairs website This class has related tables.
