a. Requires a permitted plan; andb. Changes the natural cover or topography and which may cause erosion or contribute sediment and alter the quantity or quality of stormwater runoff.
(1) Classification 1. Developed residential properties, which shall include all single-family detached units and all duplexes and developed agricultural properties.(2) Classification 2. Developed nonresidential properties, which shall include but not be limited to triplexes; apartment buildings and complexes; condominiums, boardinghouses; commercial properties; industrial properties; parking lots; recreational, institutional, and governmental facilities; hotels; offices; schools and other educational facilities; theaters and other facilities for performance; and churches and other religious institutions and facilities.(3) Classification 3. Undeveloped residential properties and agricultural properties.(4) Classification 4. Undeveloped nonresidential properties.
a. Impervious surfaces shall mean those hard surfaces which either prevent or retard the entry of water into the soil and include such surfaces as roof tops, asphalt or concrete paving, driveways, parking lots, walkways, sidewalks, patio areas, storage areas, graveled areas, or other surfaces which affect the natural infiltration.b. The city engineer shall determine the amount of impervious area on each developed nonresidential property. The determination will be made using information derived from digital and other photographic data, Greenville County and Spartanburg County Geographic Information System (GIS) data, and other additional information, if available, to supplement such data. Upon written request to the city engineer, an owner, or lawful occupant obligated to the owner for payment of the stormwater fee shall be provided with a written determination of the amount of impervious area for which the stormwater fee was charged.c. The city engineer shall determine the mean average amount of impervious surface on all developed residential properties in the city using a statistical process. This mean average shall constitute the equivalent residential unit (ERU) that shall be used to calculate the fee for residential and nonresidential parcels.d. The ERU shall be the billing unit used in the formula for calculating the stormwater fees for each parcel. The number of ERUs for all developed and undeveloped residential properties shall be one. The number of ERUs for all developed nonresidential properties shall be determined by the amount of impervious area on the property divided by the ERU and rounded up to the nearest whole integer. The number of ERUs for all undeveloped nonresidential properties shall be one.
a. Classification 1. The stormwater fee for all developed residential properties shall be calculated by multiplying one ERU by the applicable developed residential property rate.b. Classification 2. The stormwater fee for all developed nonresidential properties shall be calculated by multiplying the number of ERUs calculated in subsection (1)d of this section by the applicable developed nonresidential property rate.c. Classification 3. The stormwater fee for all undeveloped residential properties shall be calculated by multiplying one ERU by the applicable undeveloped residential property rate.d. Classification 4. The stormwater fee for all undeveloped residential properties shall be calculated by multiplying one ERU by the applicable undeveloped nonresidential property rate.
(1) The fee ERU shall be $21.60 per ERU annually.(2) For all classification 2, the fee shall be calculated based on the amount of impervious surface on the property.(3) For classifications 1, 3, and 4, the fee shall be calculated on one ERU.
