HCGUG Data SIG

  • To assist Hennepin County in creating an accurate primary key field that will always be up to date.
  • To accurately display all addresses on parcels.
  • To help create common county wide data sets.
1. How to eliminate or, at least, minimize the time it takes for a proper PID to appear on a parcel once it has been created or altered.

Currently, a parcel in transition at the County is given a PID of 0. This weakens the potential of the PID to serve as the primary key for parcels since many parcels then have a PID of 0. Possible solutions might include speeding up the assignment of PIDs, or assigning a temporary unique PID.

2. How to eliminate instances of multiple PIDs for residential parcels with the same address.

In some cases, a normal residential parcel with one single-owner structure and one address may be divided and assigned two different PIDs. This can occur when a property is bisected by a school district (as shown in the illustration) or watershed boundary. Solutions might include having the resident apply to the school district for inclusion in one district only, or making the developers aware of this issue before they plat a new subdivision.
3. How to handle multi-addresses on single-owner properties (such as duplexes).

In situations where one individual owns a property with two addressed units, such as a duplex, the parcel file typically lists only one address. There currently is little done to adequately track these addresses. Some information is maintained at the both the city and county level.

4. How to handle multi-addresses on single-owner lots (such as strip-malls or apartments).

Similar to the duplex situation above, some property is owned by one entity, but there are many valid addresses located on the property. The parcel file from the county would typically only show a single parcel address. Any solution to this issue is likely to have numerous issues to resolve, and efforts are already underway at MetroGIS to create a GIS point layer of all valid addresses in the seven-county metro area. The Data SIG will look at ways for HCGUG to partner with MetroGIS to find a viable solution for Hennepin County.
