Survey
The Study Group has contracted Jack Myers from DuFresne-Henry to do the neighborhood survey and come up with alternative designs for stormwater management. The engineer has started his work. We will be reporting his progress on these pages.
Step 1.
For this area there is high-resolution, remote sensing information called LIDAR. Based on LIDAR data and visual analysis of the surveyed area, Jack came up with this dilineation of the neighborhood area into sub-catchments. The red lines show areas in the watershed that collect water and drain at one particular point. In some cases the drain is an artificial pipe (marked in yellow). In some cases it drains naturally into another sub-catchment. The topo lines are shown in blue (not very well seen on the jpg images - download the full pdf file to see them). Along each line the elevation is the same. So where you see the lines densely packed, we have a steep slope. Areas with no lines are almost flat.

By simply looking at this image we can already identify certain possible problems and solutions.
