iw" ..L S/2& 19 7 . �lj'll)iday Point 570 - Glenn Kinderman, Kevin Conners, Mary Napier , and I walked over this lakefront community with a water problem . A 1 /4-square mile watershed drains through the area. Prior to o the lake horiie construction, there was no problem since the water could flow in a natural open channel to the lake. Now, a street and a row of homes effectively blocks the flow of the runoff to the lake. An attempt has been made to force the runoff through a low head culvert system with very little capacity. Part of the culvert is built above the natural ground level and higher than the driving head elevation west of the street. The result is flooding west of the street until it overf lows into the homes along the lake causing a lot of problems . One way to correct the problem is to re-establish the ripen channel to the lake with enough designed capacity to handle the desired design storm. This would be difficult to do now without removing a home or two. Also, the road culverts would need to be enlarged to handle more flow . .The best method that I see now is to develop more storage capacity west of the street. This could be done in conjunction with the planned apartment development in the area. This would require some innovative landscaping and engineering to balance the discharge and storage through the system. Professionals need to be retained for these tasks . I see apartments around a multi-purpose, pleasant pond that provides temporary flood storage, sediment trapping, and recreational and visual benefits . For this to happen, it will take a cooperative effort of the entire community to express their problems and needs . A group approach is needed with a will iness for everyone to pay their fair share based on benefits derived . A leader should be selected to explore ways of financing capital improvements . An engineer with landscaping expertise should be retained to assist with the planning and final designs . Operation and maintenance need to be provided for so that the system is long lasting. If this scenario can be fulfilled, I see the creation of a pleasant community with most of its water problems solved . If not, I suspect the area west of the street will still be developed, possibly causing more water problems for the lake owners . With our present workload, I do not expect that further planning and design assistance will be available from us . We are always available to answer questions that their selected consultants might have in our area of expertise . Joseph H.
