Staff Consensus Recommendations:
1. For all vacant lots north of 51 st Street which abut wetlands or ponds, the lowest floor elevation would be
953.5.
2. For existing homes without COs, lowest opening cannot be lower than 953.5, except Lot 7, Block 2 which
can stay as is.
3. Lots 8 and 9, Block 2 would need to be slab homes at an elevation of at least 953.5.
4. The Developer wouid need to provide a modified drainage plan for approval by the City.
5. The City Engineer will evaluate the modified drainage plan as to the homes south of 51st Street.
6. We are proposing to modify the PUD to provide for these elevations.
7. If approved by the City Council, the Developer will need to procure all necessary signatures to amend the
PUD.
