In 1987, a new house was built on 525 Orchard Park Road and there has been speculation that <br /> the draintile system may have been damaged during the driveway construction. However,we do <br /> not have any positive proof that the draintile was damaged at this time. The Pinnacle Report <br /> alleges that in 1994 the property owner of 615 Orchard Park Road did work that impacted the <br /> drainage in this area. In my recent phone conversation, this property owner stated that he has not <br /> done anything impact the drainage in this area. Since this area is all private property, any <br /> drainage projects would require easements from the property owners, and this property owner is <br /> not interested in granting any easements for a drainage project. <br /> Conclusion and Recommendations <br /> This area was draintiled in the 1950's,the exact location and type of system installed is unknown <br /> along with how good the system actually did function. Common practice at that time was to <br /> install short lengths of clay pipe for draintile systems. This system is 50 years now, and the fact <br /> that it is not functioning properly anymore is not surprising. There have been differing opinions <br /> and allegation presented regarding this situation which does not provide any conclusive proof of <br /> exactly what has transpired in this area. This area is all private property with almost all of water <br /> draining off private property,with only a very minimal amount of water draining from City or <br /> County Roads. The acquisition of easements would be required in order to complete a drainage <br /> project and obtaining cooperation from all of the property owners could be difficult. <br /> The City's policy for selecting drainage projects over the past several years has been to rank <br /> projects in the following priority order. <br /> • Projects to prevent flooding of structures. (No buildings are being threatened by the water <br /> levels in this area.) <br /> • Projects to prevent or correct erosion problems. (There is no existing erosion or the <br /> potential for future erosion in this area.) <br /> • Projects to correct wet areas with no structure damage or erosion are the lowest priority <br /> In addition,the City funded drainage projects selected over the past several years were in high <br /> density developed areas with substantial drainage from City streets. This project is in the low <br /> density 5 acre zoning area with virtually no public road drainage causing problems. <br /> Another consideration is the high value the City places on wetlands and ponds to reduce peak <br /> flows and improve water quality, so the completion of a project to drain a wetland and convey <br /> stormwater flows downstream faster is not in conformance with Orono's values and policies. <br /> The City's long term plan is for more ponding to treat stormwater. <br /> Also before the 1950's draintile installation to'allow farming this area was wetlands, and with the <br /> draintile failure is reverting back to the previous natural conditions. <br /> The staff recommendation is that this drainage issue is a low priority in terms of the City's <br /> overall goals and policies for wetland protection, stormwater treatment, drainage goals, and the <br /> current drainage situations. <br />
