Flood Plain Determinations & Resolutions

Flood Plain Determinations & Resolutions

Flood insurance costs are determined by the National Flood Insurance Program which is a federally backed program. Lane S. Bishop & Associates Land Surveying can help you through this process.

One of that main determinations of the flood risk is the information on the relation between the elevation of the lowest floor of a structure and the base flood elevation which is found on the Elevation Certificate.

Elevation Certificates

An Elevation Certificate documents your building’s elevation. If you live in a high-risk flood zone, you will need an Elevation Certificate before you can obtain an accurate flood insurance policy quote.

Whether you’re being asked for elevation certification by a lender, or whether you are requesting it on your own, it’s important to have accurate results so that you are aware of the risks in purchasing the property, as well as to keep your insurance premiums as low as possible.


Letter of Map Amendment (LOMA) is an official amendment, by letter, to an effective National Flood Insurance Program (NFIP) map. A LOMA establishes a property''s location in relation to the Special Flood Hazard Area (SFHA). For More info: Click Here

Wetland Determination

The boundary of the wetlands is determined by observing the soil colors, vegetation, erosion patterns or scour marks, hydrology, and morphology. Typically colored flags are then placed in key locations to denote the boundary of the wetlands.

A survey is done to collect the data on the locations of the placed flags and a plan is drawn to reference the boundary of the wetlands against the boundary of the surrounding plots or parcels of land and the construction work proposed within.

Drainage Basin Mapping

A drainage survey is also commonly known as a drainage inspection and its purpose is to inspect the pipes in your home in order to see if there are any problems with them.  Drainage surveys are done before buying a home to see if there are any problems with the pipes that could cost you serious money or when you just can’t work out why water is not draining away as it should.

Surface Water Mapping

Environmental changes and their impacts on natural systems and human societies are topics of research in a wide range of scientific fields. Surface water is among the most vital earth resources undergoing changes in time and space as a consequence of land use/cover changes, climate change and other forms of environmental changes in many parts of the world. The ecological, social, health and economic effects of surface water changes have been the subject of academic study for many years.

Changes in surface water may result in disasters such as flooding, outbreaks of waterborne disease and water shortage in dry tropical areas, which may involve loss of lives. Timely monitoring and delivery of data on the dynamics of surface water are, therefore, essential for policy and decision making processes
