The data illustrates the “Urbanized Area” for the Municipal Separate Storm Sewer System (MS4) program from the 2010 census. "Urbanized area" means a place and the adjacent densely populated territory that together have a minimum population of 50,000 people, as defined by the United States bureau of the census and as determined by the latest available decennial census. The data is provided to the Michigan Department of Environment, Great Lakes, and Energy (EGLE) by the United States Environmental Protection Agency. The urbanized area is the regulated area for municipalities that are regulated under the MS4 program, including but not limited to cities, township, and villages."2020 Census Populations of 50K or more" and "Automatically Designated Areas" was provided by US EPA in July 2023 and combined with Michigan Open GIS Data (Minor Civil Divisions: Cities, Townships and Villages) using ESRI's ArcGIS Pro Software. Tools used include Pairwise Intersect, Merge, Pairwise Erase, and manual editing to combine the two layers.Please contact the individuals below with any questions.Christe Alwin: ALWINC@michigan.gov (point of contact)Patrick Klein: kleinp3@michigan.gov (creator)

1m Contours derived from the 2023 1m DEM for the urban areas. The 1m DEM was generated from LiDAR data that was captured at the request of Porirua City Council by Landpro between 08/01/2023 and 16/04/2023 using the projection NZTM NZGD200 and vertical projection of NZVD16. The dataset was calibrated and classified by Landpro using automated and manual processes from which surface features were removed generating in a 1m bare earth DEM. The DEM provided by Landpro was smoothed by Porirua City's GIS team using a 3x3m grid with a neighborhood moving average prior to running the contour tool. Any contours less than 5m in length were removed. To reduce loading times, contours were clipped using the Pairwise Intersect tool and a 500m fishnet layer.
