STORM WATER REGULATIONS · Storm Water Phase I program has been in place since 1990 and was a result of the 1987 Amendments to -- the Federal Clean Water Act. · The Phase I program applies to storm water discharges for industrial activities and construction sites over 5 acres and medium to large cities with populations over 100,000. STORM WATER REGULATIONS I I I I I I I I I I I I I I I · Storm Water Phase II Rule was ~mplemented in 1999 by the Environmental Protection Agency (EPA), but is being phased in from 1999 to 2003. · The Phase II program applies to storm water discharges for construction sites over 1 acre and small cities with populations over 10,000. STORM WATER REGULATIONS I I I I I I I I I I I I I Il · Purpose of the new regulations is to reduce and prevent sediment & pollutants from entering the streams and rivers from the mumcipal storm water systems. · The City of Iowa City must submit a Storm Water Management Plan in March 2003 to the Iowa DNR that contains six m~nimum control measures.

Pollution Prevention & Good Housekeeping Municipal staff training and programs Set goals on pollution prevention techniques including: street sweeping cleaning of intakes leaf pick-up accidental spill containment These services cost money I I I I I I I I I I I I I I I We are going to manage storm sewer and storm water as we have water and samtary sewer as a separate utility The annual cost of these services is estimated at $800,000. Includes $150,000 for storm sewer replacement and/or new STORM WATER UTILITY FEE I I I II I I I I I I I I I I 1 The allocation of storm water and storm sewer costs to those that contribute. Fee will be proportional to the amount of storm water a property contributes. The amount of storm water that runs off a property is proportional to the amount of impervious surface on the property. STORM WATER UTILITY FEE Impervious surface is any hard surface that doesn't allow rain water to penetrate or soak in such as a building roof or a surface constructed of concrete or asphalt pavement such as driveways, parking lots and sidewalks.

STORM WATER UHLITY FEE I I I I I I I I I I I I I I I The second step is to measure all of the commercial and industrial properties. These properties each have to be measured rather than using an average because the amount of hard surface vanes more than on residential properties. STORM WATER UTILITY FEE The next step is to measure some of the multi family residential units, and calculate the average hard surface of a 4-plex, 8-plex, 12- plex, and anything above a 12-plex. STORM WATER UTILITY FEE I I I I I ~ I I I1 I I I I I The aerial photography and mapping is essential to creating a storm water utility fee. We can determine the amount of hard surface from site plans or field measurements but it will take at least twice as long if not longer. You can zoom in with computer software to measure.the building and driveway areas quickly and accurately.
