Q. What is a 100-year floodplain?
A. It is the area of land inundated by floodwaters from a storm that has a 1 percent probability of being equal to or exceeded in any given year.
Q. How do I know if my house is in the floodplain?
A. Visit the FEMA Map Service Center https://msc.fema.gov/webapp/wcs/stores/servlet/FemaWelcomeView?storeId=10001&catalogId=10001&langId=-1&userType=G and search for your address. If you have additional questions, contact Engineering Services at (972) 292-5400.
Q. What is the difference between FEMA-designated zones A, AE and X?
A. Zone A is an area of the 100-year floodplain that has not been studied in sufficient detail to determine the water surface elevation of the 100-year flood. Zone AE is the area of the 100-year floodplain with the elevation of the 100-year flood available and the floodway designated. Zone X is an area inundated by the 500-year storm or areas outside of land inundated by the 500-year storm.
Q. I have an easement on my property, what is it for?
· General utility easement - this is for any underground or above ground utility such as gas, electric, water, sewer, etc.
· Specific utility easement (such as electric easement or water easement) – this is for that specific utility only. (A gas line cannot be in a water easement.)
· Access easement – grants access across the property to serve another property.
· Drainage easement – this is for anything stormwater-related, including the following:
• Underground storm sewer including inlets and outfalls.
• Above ground drainage, such as a channel or a flume.
• Floodplain – As property is developed, a drainage easement is dedicated to protect the floodplain.
• Detention/retention – A drainage easement is dedicated to cover detention ponds and underground detention structures.
