Public Works Committee 5. 9. Meeting Date: 09/18/2012 Submitted For: Shane Nelson By: Shane Nelson, Engineering/Public Works Title: Review of Miscellaneous Storm Water Appurtenances in the Vicinity of Lake Ramsey Background: We have observed several large storm water appurtenances in the vicinity of Lake Ramsey. We understand that most of these structures are remnants from the original development. We have completed an inventory (attached) and have determined what items are usable or salvageable and which items should be recycled or discarded. In addition to the pipe, it appears that this area is becoming a dump site for discarding used silt fence, concrete rubble and other miscellaneous items. Notification: n/a Observations: The structures near the intersection of Zeolite and Bunker Lake Blvd are very visible. The large diameter top slabs and bottom slabs are likely salvageable and one of each could possibly be used for the trunk storm sewer on Zeolite. The large diameter manhole structures are in usable condition; however the City does not currently have a use for them and may not have a use for them in the future. The rest of the pipe is somewhat screened by the tree line on the east side of Lake Ramsey. The pipe that is damaged has no real value. These pipes and structures should be crushed with the rubble being removed from the site and recycled. The pipe that is salvageable is only good if the City has a use for it. If the pipe is moved several times, we anticipate that it will get damaged. Most of the pipe is too heavy for the City to move using its equipment. It will be necessary to move the pipe if Lake Ramsey is continued to the east. As the COR continues to develop, we understand that Lake Ramsey will continue to be excavated to the east for fill. Funding Source: We anticipate that the HRA would be the funding source Staff Recommendation: Staff is recommending removing all of the damaged and unusable material from the site to clean it up for future use , so as not to be a concern for future development. We are seeking direction on the salvageable or usable material. These items could be removed or remain in place and made available to future site developer's within the COR. Committee Action: We are seeking a recommendation on what options to explore, if any, for the remnant pieces of pipe and manholes in the vicinity of Lake Ramsey. Inventory Attachments
