FOR THE CITY OF AMES,IOWA
WHEREAS, the Water Pollution Control Facility(WPCF) is being converted to a nutrient
removal treatment technology. Additionally,watershed-based nutrient reducing improvements are
being performed by the City, banking credits with the Iowa Nutrient Reduction Exchange (NRE)
toward any future, more stringent nutrient reduction regulations imposed on the WPCF; and,
WHEREAS, in partnership with the Iowa Department of Agriculture and Land
Stewardship (IDALS), Ducks Unlimited, and Story County Conservation, a 20.9 acre constructed
wetland is being designed northwest of Ames near the Prairie Valley subdivision. Referred to as
the Dotson Wetland, it will be located at the outlet of a large county drainage district that currently
discharges directly into Ioway Creek. The wetland will ultimately treat subsurface drainage from
over 2,200 acres of farmed land. The modeled nitrogen mass removal rate of the wetland will be
approximately 22,000 pounds per year, which will be entered into the NRE annually to receive
nutrient reduction credit; and,
WHEREAS, the total cost of construction for the wetland will be covered by IDALS and
the wetland will be constructed on property owned by Story County. IDALS will contract for the
construction of the wetland. Following construction, the City will own and maintain the
infrastructure associated with the pump station. Story County will provide vegetation maintenance
as needed for the wetland. In the event of catastrophic damage, such as by significant flooding,the
City and the County will share the cost of repairs.
