This model layer represents the combined local Engineering Firms drainage studies for each drainage basin in displaying the 100 Year Flood Limits by polygon boundaries. This model layer defines the areas that will be subject to development restrictions referenced in the 2018 Field Drainage Prevention Ordinance. This model layer is to provide assistance in identifying specific local areas of problematic drainage resulting from a 100 Year 24 hour storm event. CITY ZONE 'M' - means an area defined through hydraulic modeling or other standard engineering analysis as described in Article B, Section 8-70 of the Stormwater Field Drainage Prevention Ordinance. |
