'� , • � � 1. A floodplain permit is needed for the structures (gazebo and picnic shelter) that are to be built in the floodplain. I have completed much of the permit for you (see attached). Please attach to the permit a drawing that shows that these structures are not enclosed. Therefore they do not need to be elevated. Please complete the blanks marked with an "x". Make sure to fill in the flood elevation information at the upstream side of each structure. A copy of the floodplain use permit is enclosed. The application fee is waived fo� City departments. 2. Please include on the plat the floodplain and floodway Iines for the fully developed eondition hydrology. 3. On the drainage plan, the floodplain line near the western edge of the property does not appear to match the Anderson fully developed condition report. Please review and revise as necessary. 4. The dumpster in the parking lot will need to either be relocated out of the floodplain or anchored at all times so that it will not float during a flood. The dumpster enclosure is not considered secure enough for flooding purposes. We strongly recommend moving the dumpster out of the floodplain.. 5. Please secure fhe bike racks, picnic tables, etc. that will be placed in the floodplain so that they will not float during a flood. Please make a note in the drainage report that this has been done. 6. Drainage report, P.1. Please describe in more detail the floodplain analyses that were done for this project.

They now show what I guess is an envelope, but they haven't labeled it. Also; they've shown the distance from buildings to lot lines, but haven't shown dimensions of the envelopes.

But it's nofi elear to me from the landscape plan that there is more than 1 phase. If there are going to be multiple phases, need to make sure phase lines are shown on landscape plan.
