MARGARET CREEK SUBDISTRICT

OF THE HOCKING CONSERVANCY DISTRICT 

ASSESSMENT METHODOLOGY RULES

The total assessment levied upon each parcel is based upon an estimate of the total runoff from each property which will be determined as follows: 

80% of the total annual assessment based upon the impervious area of the parcel, plus,

20% of the total annual assessment based upon the remaining pervious parcel area. 

A Statistical Sample (95% Confidence Level with 5% Confidence Interval), or approximately 336 out of 2,664 non-vacant residential parcels, were measured to determine the typical impervious area for each residential parcel which will represent one (1) ERU (Equivalent Residential Unit).  

All Single Family Residential (SFR) will be charged one (1) ERU plus the remaining non-impervious area of the parcel times the rate for pervious area. 

All Two Family Residential and larger have had the impervious area measured and the ERU's for each computed along with the rate for pervious area. 

Condos with individual lot numbers will have the impervious area measured and each parcel assessed individually.  Common areas will be measured and prorated across each individual condo unit along with the rate for pervious area. 

Condos without individual lot numbers for each unit will be measured as a group and the underlying parcel assessed.

Each individual Condo unit in a multi-story building will be subject to assessment.  The apportioned assessment will equal one-half ERU.

Manufactured home parks will be considered as one parcel, the impervious area measured for the entire parcel and the mobile homes counted and multiplied by an average impervious area per unit.  

All vacant parcels will be assessed one ERU. Vacant parcels with pervious area greater than 26.5 acres will be charged one ERU plus the rate for the pervious area in excess of 26.5 acres. 

All non-vacant Agricultural Parcels will be charged one ERU plus the rate for pervious area.

All non-vacant Commercial and Industrial properties will have the impervious area measured and ERU determined along with the rate for pervious area.

All US Government and State of Ohio Parcels will be considered exempt from this assessment based on current State and Federal law.

All State owned College or University parcels (LUC 670) would be considered exempt in accordance with State Law.

All other 600 Class Tax Exempt parcels are subject to assessment.

Public and Privately owned graveyards or cemeteries will not be assessed.  However, churches adjoining cemeteries will be assessed.

All 800 Class Public Utility parcels will be subject to assessment.

Any parcel with a computed assessment less than $2.00 will be assigned an assessment of zero ($0.00) in accordance with State Law.

The total annual assessment for any parcel, or two or more contiguous parcels with the same owner of record, shall not exceed $2,000.00.

Those parcels with no Auditor assigned Land Use Code, an estimated 319, are exempt from assessment unless it is determined that such parcels contain buildings or impervious area that should be included under this assessment.

All Streets and Highways are considered part of the stormwater drainage system and as such are not subject to assessment.

All gravel parking lots and driveways will be considered pervious area and not included in impervious area measurements.  Gravel piles associated with aggregate mining areas will not be measured.

Because the Auditor's "Acres" file for all parcels is not complete, the computed GIS polygon area for the parcel will be used to compute the assessment.   For those parcels for which the impervious area is measured, the difference between the recorded parcel acreage and the polygon area will be computed and if this difference exceeds 10%, the area will be reviewed. 

Parcels completely outside the Margaret Creek Watershed boundary, but within the Subdistrict boundary, will not be assessed. 

Parcels that straddle the watershed boundary or Subdistrict boundary will be assessed based upon the entire parcel area.   

Note: "Impervious Area" being defined herein as that part of a developed parcel that has been modified to reduce the land’s natural ability to absorb and hold rainfall. It includes hard surfaces, which cause water to run off the surface in greater quantities or at an increased rate of flow from the flow that existed under natural conditions prior to development. For example, common impervious areas include, but are not limited to, rooftops, walkways, patios, courtyards, driveways, parking lots, storage areas, and any concrete or asphalt paving. 

         "Pervious Area" being defined as the remainder of the parcel area.
