Index of drainage maps in the City.

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.

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) area-Combined Sewer System (CSS) area-Watershed, Subwatershed, HUC12, HUC14, HUC16-Ward, ANC, SMD, and the address of the location-Census Tract and zip codeFor 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.Created with the Information Lookup Template from ESRIhttps://dcgis.maps.arcgis.com/home/item.html?id=54da82ed8d264bbbb7f9087df8c947c3

CSO attributes and location information are from a variety of datasets for each state: Connecticut: Beginning with GIS data compiled by the Connecticut Department of Energy and Environmental Protection (“CT DEEP”) and displayed on their CSO Right-to-Know site (https://portal.ct.gov/DEEP/Municipal-Wastewater/Combined-Sewer-Overflows-Right-to-Know), EPA filtered the data for the purposes of this map and made corrections based upon updated information available in EPA’s files. EPA’s map only displays municipalities with CSO outfalls, whereas CT DEEP’s map includes municipalities with CSO-related bypasses at their Wastewater Treatment Facilities (but no Combined Sewer Collection System CSO outfalls). EPA’s map only displays CSO outfalls – the point at which CSOs are discharged to the receiving water - whereas CT DEEP’s map includes CSO regulators (the structure through which wastewater and stormwater exits the conveyance pipe towards the Wastewater Treatment Facility). Maine: Service containing both facility and outfall locations permitted under the Maine Pollution Elimination System (MEPDES) and administered by the Maine Department of Environmental Protection (MEDEP). The data has been collected using multiple methods over 2 decades under the direction of the Maine DEP GIS Unit. All location data was quality checked by MEDEP MEPDES Inspectors and GIS Unit staff in 2018. Massachusetts: Attribute and location information from a combination of MassDEP CSOs(https://mass-eoeea.maps.arcgis.com/apps/webappviewer/index.html?id=08c0019270254f0095a0806b155abcde) (metadata - https://mass-eoeea.maps.arcgis.com/home/item.html?id=0262b339c2c74213bdaaa15adccc0e96) and NPDES permits(https://www.epa.gov/npdes-permits/massachusetts-final-individual-npdes-permits). New Hampshire: Active CSO outfalls collected from NH NPDES permits(https://www.epa.gov/npdes-permits/new-hampshire-final-individual-npdes-permits). EPA made corrections based upon updated information available in EPA’s files. Rhode Island: RI CSO Outfall Point Features. The outfalls managed by the Narragansett Bay Commission are downloadable from a GIS file through RIGIS (Rhode Island Geographic Information System https://www.rigis.org/datasets/nbc-sewer-overflows/explore?location=41.841121%2C-71.414224%2C13.57&showTable=true).

City of Cambridge, MA, GIS basemap development project encompasses the land area of City of Cambridge with a 200-foot fringe surrounding the area and Charles River shoreline towards Boston. The basemap data was developed at 1" = 40' mapping scale using digital photogrammetric techniques. Planimetric features; both man-made and natural features like vegetation, rivers have been depicted. These features are important to all GIS/mapping applications and publication. A set of data layers such as Buildings, Roads, Rivers, Utility structures, 1 ft interval contours are developed and represented in the geodatabase. The features are labeled and coded in order to represent specific feature class for thematic representation and topology between the features is maintained for an accurate representation at the 1:40 mapping scale for both publication and analysis. The basemap data has been developed using procedures designed to produce data to the National Standard for Spatial Data Accuracy (NSSDA) and is intended for use at 1" = 40 ' mapping scale. Where applicable, the vertical datum is NAVD1988.Explore all our data on the Cambridge GIS Data Dictionary.Attributes NameType DetailsDescription TYPE type: Stringwidth: 50precision: 0 type of drainage (ditch, sewer or drain crossing, ect)

This feature class represents current stormwater conduits within the City of Los Angeles. This conduit is used in conjunction with a pumping station. 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.For a complete list of attribute values, please refer to (TBA Stormwater data dictionary).Stormwater conduit lines layer was created in geographical information systems (GIS) software to display the location of stormwater drainage pipes. The layer consists of spatial data as line features and attribute data for the features. The lines are entered manually based on stormwater maps, and information about the lines is entered into attributes. The Stormwater Network dataset is a geometric network, with a collection of conduit lines and inlet points having a connectivity relationship. Thus, editing the location of an conduit line affects the location of the connected inlet point, and vice versa. Conduit plans and specifications proposed under private development are reviewed and approved by City of Los Angeles, Department of Public Works, Bureau of Engineering. For more information on conduit materials and structures, look at the Bureau of Engineering Manual, Part G, Storm Drain Design, G 600 Storm Drain Structures section, and a copy can be viewed at http://eng.lacity.org/techdocs/stormdr/g600.pdf, or at http://eng.lacity.org, click Technical Info, click Technical Document Center, click Storm Drain Design Manual Part G, click G 600 Storm Drain Structures.

Stormwater Pipe/Conveyance Lines in Fuquay-Varina. Please note that many of the stormwater line features represent privately owned and maintained pipes, and these are essential for mapping and understanding the stormwater drainage network sub-systems at the neighborhood level. Please pay attention to the Subtype field to identify the different categories of public vs. private and culvert type stormwater lines. Directionality (start vs. end vertices) of these line features reflects real world flow direction. The GIS data in the area of Downtown Fuquay-Varina has a lot of old and erroneous stormwater features. A project is currently underway to correct much of this inaccurate stormwater data. Please note that ALL public utility data layers can be downloaded in a single .mpkx (ArcGIS Pro map package file), updated every Friday evening. This .mpkx file can be opened directly with ArcGIS Pro version 3+. Alternatively, you can extract the file geodatabase within it by renaming the file ending .mpkx to .zip and treating it like a zip archive file, for use in any version of ArcGIS Pro or ArcMap software. You can also use QGIS, a powerful, free, and open-source GIS software.The Town of Fuquay-Varina creates, maintains, and serves out a variety of utility information to the public, including its Potable Water System, Sanitary Sewer System, and Stormwater Collection System features. This is the same utility data displayed in our public web map. This utility data includes some features designated as 'private' that are not owned or maintained by the Town, but may be helpful for modeling and other informational purposes. Please pay particular attention to the terms of use and disclaimer associated with these data. Some data includes the use of Subtypes and Domains that may not translate well to Shapefile or GeoJSON downloads available through our Open Data site.

Status: NOT MAINTAINEDContact: GIS_IT, City of Tucson Information Technology GIS Services, 520-791-4747, GIS_IT@tucsonaz.govIntended Use: For map display and provides finer level of detail than Pima County GIS library data layer WASHES.Supplemental Information: DATA QUALITY IS QUESTIONABLE because it has not been regularly maintained. 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.

More MetadataHistoric drainage is used in agricultural and farm plans, stormwater management, comprehensive planning, floodplain management, and facility planning to provide a better understanding of what previous drainage was like for a given area. Soils were originally shown at the scale of 1:15840 and then redrafted to 1:20000; the data were redrafted a final time to fit Loudoun County's base map standard of 1:2400. Although the current data rely heavily on the original soil survey, there have been extensive alterations. The data are updated as field site inspections or interpretation changes occur. This is a copy of the drains layer as it exists on 20010208. It is meant to provide the county with a historical base for drainage.Photogrammetric updates will not occur to this layer. Data are stored in the corporate ArcSDE Geodatabase as a line feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN (vertical datum, if applicable, NAVD88), US Survey foot units.
