  § 18-63. Surface water management.  

Latest version.

  • (a)

    All subdivisions shall comply with the city's surface water management plan dated August 2006, which is incorporated herein by this reference.

    (b)

    In accordance with the city's surface water management plan as a condition of subdivision approval, subdividers shall pay a water quality and water quantity connection charge. The charge shall be based upon the gross area of the subdivision less the area to be dedicated to the city for ponding, parks and wetland, and right-of-way for state highways, county roads, and local arterial roadways. The connection charges per acre for water quality and water quantity are outlined in subsection 4-30(c)3. The subdivision will be given a credit for on-site stormwater quality improvements that are designed to treat runoff from the subdivision to NURP standards. The credit will be calculated using the following formula: The per acre water quality connection charge will be multiplied by the on-site drainage area for water quality treatment facilities. This value will then be multiplied by 50 percent. The subdivision will also be given a credit for on-site stormwater quality improvements that are oversized to treat runoff from property outside the subdivision to NURP standards. The credit will be calculated using the following formula: The per acre water quality connection charge will be multiplied by the off-site drainage area for water quality treatment facilities. This value will then be multiplied by 50 percent. Credit will not be granted if the stormwater from contributing off-site areas is already treated to NURP standards. The water quality connection charges that correspond to the land uses that contribute to the stormwater ponds will be used to calculate credits.

    The charge for lots oversized due to individual on-site sewage disposal and water systems will be reduced to the charge that would be imposed on a one-half-acre lot. An additional charge will then be imposed if the lot is further subdivided less a credit for the charge previously paid. The charge shall be paid in cash before the subdivision is approved by the city unless the city and subdivider agree that the charge may be assessed against the property. Property being subdivided shall be exempt from the water quality and water quantity connection charges imposed by this section if the charges were paid or assessed in conjunction with a previous subdivision of the property and if the property is not being zoned to a classification with a higher charge.

    (c)

    Within the Bluff Creek Overlay (BCO) District, meet the additional purpose, intent and standards of the BCO District.
