Final answer:
To meet Basic Rule #3 in a riverine AE Zone with a base flood elevation, a developer must demonstrate that they are maintaining the current level of the water table, which is critical to the ecosystem.
Step-by-step explanation:
In order to demonstrate that a developer is meeting Basic Rule #3 in a riverine AE Zone with a base flood elevation, they must show that they are maintaining the current level of the water table, which is critical to the ecosystem.
This can be achieved by taking measures to minimize the impact of the development on the water table, such as implementing stormwater management strategies, using permeable surfaces, and properly managing groundwater withdrawal from wells.
By effectively addressing these concerns, the developer can ensure that they are meeting Basic Rule #3 and minimizing negative impacts on the environment and the surrounding ecosystem.
