The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The Address Ranges Feature Shapefile (ADDRFEAT.dbf) contains the geospatial edge geometry and attributes of all unsuppressed address ranges for a county or county equivalent area. The term "address range" refers to the collection of all possible structure numbers from the first structure number to the last structure number and all numbers of a specified parity in between along an edge side relative to the direction in which the edge is coded. Single-address address ranges have been suppressed to maintain the confidentiality of the addresses they describe. Multiple coincident address range feature edge records are represented in the shapefile if more than one left or right address ranges are associated to the edge. The ADDRFEAT shapefile contains a record for each address range to street name combination. Address range associated to more than one street name are also represented by multiple coincident address range feature edge records. Note that the ADDRFEAT shapefile includes all unsuppressed address ranges compared to the All Lines Shapefile (EDGES.shp) which only includes the most inclusive address range associated with each side of a street edge. The TIGER/Line shapefile contain potential address ranges, not individual addresses. The address ranges in the TIGER/Line Files are potential ranges that include the full range of possible structure numbers even though the actual structures may not exist.

The United States Environmental Protection Agency (USEPA) requires Michigan to attain the National Ambient Air Quality Standards (NAAQS) for six criteria pollutants. The data contained in this layer file outlines the statewide nonattainment areas and maintenance areas for the 2015 Ozone NAAQS as designated by the USEPA. The nonattainment areas consist of two partial counties (Allegan and Muskegon) and one full county (Berrien) located on the west side along Lake Michigan. In southeast Michigan there is a seven-county Attainment/Maintenance area. Further information about the six criteria pollutant NAAQS and Michigan’s ozone designation status can be found on EGLE Air Quality Division’s SIP and Attainment webpage.

Stress Analysis used factors that would contribute to uncomfortable situations were aggregated and mapped to show how stressful segments of roads were for walkers and bikers. The different factors were a value and weighted depending on how much the factor attributed to stress. Berrien County Trails Master Plan 2022Online Map

Road Ownership Layer Attributes DescriptionsFederal Aid Status:

Determines if the road is able to use the Federal Surface Transportation Program (STP) funding source. STP is allocated through an MPO, RTF, or small urban program. In Berrien, Cass and Van Buren Counties, the SWMPC manages all of these programs, except for areas within the KATS MPO.

Urban/Rural

Urbanized: A census Designated area with a population of 50,000 or more. All urbanized areas are part of an MPO.

Small Urban – A census defined area with a population between 5,000 and 49,999.

Rural: Any area outside a small urban or urbanized area. Includes cities and villages with a population less than 5,000. Areas within an MPO planning area which are still outside the designated urbanized area are eligible for both MPO and rural funding sources. STP funding in rural areas is distributed through the Rural Task Force.

Metropolitan Planning Organization (MPO)–

An MPO is a federally designated organization which conducts regional transportation planning for urbanized areas with a population of 50,000 or more. The MPO Planning Area covers the entire urbanized area as well as areas which are expected to become urbanized in the next 20 years. For TwinCATS and NATS the boundary includes the entire jurisdiction for jurisdictions that contain urbanized areas. All federal or state funded transportation projects in an MPO must be included in the MPO’s Transportation Improvement Plan (TIP) to receive approval.

There are 3 MPOs which have planning areas within Berrien, Cass, and Van Buren Counties

TwinCATS: Twin Cities Area Transportation Study NATS: Niles Buchan Cass Area Transportation Study KATS: Kalamazoo Area Transportation Study

The Southwest Michigan Planning Commission (SWMPC) staffs the TwinCATS and NATS MPOs.

Act 51 Category

Michigan Public Act 51 governs the distribution of state collected fuel taxes and vehicle registration fees. The Act51 category, also call the ‘legal system’, are set based on which agency is in charge of road maintenance and is used in the road funding formula among other factors. Roads which are not Act51 certified are not eligible to use revenue from the state.

State Trunkline is maintained by MDOT

County Primary and County Local roads are maintained by the County Road Commission

City Major and City Minor roads are maintained by the City or Village the road is located in

National Functional Classification (NFC)
