Description: Part 323, Shorelands Protection and Management, of the Natural ResourcesEnvironmental and Protection Act (NREPA), 1994 Public Act 451, as amended,provides protection from the natural hazards of coastal erosion and flooding as well asenvironmental protection of our fragile coastal areas. Part 323 identifies and regulatesHigh-Risk Erosion Areas (HREA), Environmental Areas (EA), and Flood Risk Areas (FRA) within the Great Lakes coastalzone. Recession rate studies of coastal shorelines defined HREAs in many counties during the 1980s. According to R 281.22 (22) the department shall update the recession rate studies every 10 years to reflect varying lake levels and changes in erosion rates. Of 29 counties currently designated 12 counties have not been updated since designation. Counties in the Lower Peninsula on Lake Michigan were last updated in the mid-1990s except for Berrien which was updated in 2007.

Description: This Ecoregion database was delineated by Dennis Albert for Michigan. Hierarchial units include Section, Subsection, and Sub_subsection. Ecosystem components used to distinguish major landscapes are macroclimate, physiography, soil and vegetation. In Michigan, long-term climatic records were a primary component in delineating the larger hierarchical units - sections and subsections. Physiography was used in conjustion with climatic data to refine section and subsection boundaries. At the sub-subsection level, the primary determinants of boundaries were physiography and soil conditions.
Description: This layer reflects all MDEQ recognized Sections that encompass waters and wetlands under Corps permit authority as of the October 1, 2012 Navigable Waters of the United States within the Regulatory Jurisdiction of the United States U.S. Army Corps of Engineers Detroit District.
Description: The shapefile provides the general locations and information for historic landfills in Michigan, which are not currently regulated as "Active" (active means accepting waste or in post-closure monitoring under Part 115 of Act 451). These historic landfills are usually pre-regulation (Act 87, Act 641 or Part115 of Act 451) or regulated under an early law such as Act 87. Active landfills are mapped with a seperate shape file.

Description: Rule 98(R 323.1098) of the Part 4 "Water Quality Standards" designated certain waters (contained in this shapefile) as protected from degredation. These waters include those that pass through National Parks or Shorelines, and designated Wild Rivers. This shapefile was created using high resolution NHD flowlines and the State of Michigans hydrology lines files (where no NHD existed on islands), using the descriptions found in Rule 98.This file is in the coordinate system GCS_North_American_1983. Stream lengths (in miles) were measured using the high definition NHD lines, so may not precisely match the mileage length descriptions in Rule 98.The field "OSRW_type" is either "Designated OSRW" or "Tributary to OSRW". Tributaries to the OSRW are those upstream of the designated OSRW as described in the Rule, and recieve protections as described in the Rule.
Description: This data set is part of the Michigan Geographic Framework. The framework serves as the digital base map for State of Michigan government. Specifically, this Michigan base map will consist of an Arc Info coverage which includes features and attributes based on the current TIGER/Line Files, base map features based on both the Michigan Department of Natural Resources (MDNR) Michigan Resource Information System (MIRIS) Files and an enhanced linear referencing system built from the Michigan Department of Transportation (MDOT) Michigan Accident Location Index (MALI). The Geographic Framework will serve as a common and standardized infrastructure on which all GIS users of 1:24,000 scale map data can build their applications. At the heart of the Geographic Framework will be the ability to administer programs that use location-based information and need to relate one database to another geographically. Version 14a replaces Version 13a as the current version of the Michigan Geographic Framework (MGF). A primary driving force in the creation of Framework Version 14a was the continued reconciliation of the road network and city/village boundaries with current information.

Description: Watersheds (load allocation (LA) and waste load allocation (WLA) area) of Michigans 102 USEPA approved TMDLs. Updated on: 11/6/2014"All_TMDLs_merged" feature class contains all 102 TMDL watersheds, which often are nested inside one another. Because of the spatial overlap, the individual feature classes for each TMDL (TMDL_1 through TMDL_102) should be used when overlap occurs for display and verification purposes.

Description: Determining the location and extent of protected habitats is the first step in developing conservation plans for the Great Lakes and prioritizing additional habitat for protection. All current Great Lakes habitat management plans include protection goals. However, there is no comprehensive database that can display and analyze habitats that are currently protected within the Great Lakes. A comprehensive GIS database of protected lands in the Great Lakes will be utilized by conservation organizations for conservation planning, public accountability and project collaboration. This layer will enable organizations to work more efficiently and collaborate with other organizations that could potentially leverage additional funding from a variety of sources including, but not limited to: GLFWRA, GLRI, NAWCA, FWS GLCP, and private foundations. DU and TPL have been developing protected lands layers (both fee and easement) for over 10 years through the development of a Conservation and Recreation Lands (CARL), Conservation Almanac, and National Conservation Easement Database. Through this project, we have added an additional 13,680 protected lands to the database and corrected numerous attribute and spatial errors. While the actual acreage of protected land decreased by 217,173 acres, this was due mostly to mistakes in the early version of CARL by including federal lands that were identified as acquisition areas, but were not actually protected. In addition to the CARL layer developed for this project, two additional projects were benefited. Easement data collected as part of this project was also included in the National Conservation Easement Database (NCED, www.conservationeasement.us) and the Conservation Almanac (TPL, http://www.conservationalmanac.org).
Copyright Text: Funding for the development of the Protected Land layer (CARL) was provided by a grant from the U.S. Fish and Wildlife Service’s Great Lakes Fish and Wildlife Restoration Act (GLFWRA). Matching funding was provided by the U.S. Endowment for Forestry and Communities for the National Conservation Easement Database development in the Great Lakes. Past grants for the CARL project were provided by the Saginaw Bay Watershed Initiative Network (WIN), U.S Fish and Wildlife’s Great Lakes Coastal Program, and the Michigan Department of Environmental Quality’s Coastal Program.
Ducks Unlimited (DU) would also like to acknowledge and thank the many organizations that willingly gave us the data for the development of this Great Lakes CARL layer. As part of this project, The Trust for Public Land (TPL) was subcontracted to work on the public lands, while Ducks Unlimited focused on the private lands.
