Home Browse Search

Excerpts from Plan Commission Minutes of November 5,2009 continued: Mr. Shad Edwards asked Ms. Ashe to explain what the procedure would be for someone who wanted a small turbine at their residence. Ms. Ashe stated staff did a lot of research on wind systems through mock ordinances that the National Government has released. Decatur will be one (1) of four (4) cities in Illinois that has an ordinance if this is approved. The wind energy systems will only be allowed in back yards. If it were to fall no portion of it would be able to fall in neighboring properties. Thirty (30) decibels is the standard set for noise from the property line. Thirty(30) decibels is about normal conversation level. One hundred (100) feet is the limit for height in the residential areas. The foundation must be deep enough to withstand force winds of one hundred and ten (I 10) miles per hour. The color must be neutral and must not reflect light. All FAA regulations must be taken into consideration. Chairman Smith asked what the process would be for a citizen who is interested in putting a wind energy system in their back yard. Ms. Ashe said they would need to apply as they would any other permit. A structural engineer seal would be needed if the system would generate over 20 kilowatts. Civil engineer site plans will be required for all systems. Mr. Edwards asked if the wind systems such as Sam's Club sells would be able to be attached to a resident's roof. Ms. Ashe said yes and they would have to apply for a permit. Mr. Dave Anderson asked if the maximum allowed tower height included the blades. Ms. Ashe said yes. The definitions page has the definition for extended height which is the length of the tower plus the length of one blade. Mr. John asked if City staff has been approached by anyone wanting information on this. Ms. Ashe said a couple of people have called and are waiting for the ordinance to pass. There were no objectors present. It was moved and seconded (Edwards/Anderson) to forward Cal. No. 09-52 to the City Council with recommendation for approval as presented by staff. Motion carried unanimously.
