It is possible to build and maintain a home with little or no impact on the environment. Landscaping and green lawns are not necessary or appropriate in the vicinity of a lake. Many waterfront homeowners understand this and act accordingly. Unfortunately some people don't have a clue or don't care.

Unless the house allows water to pass completely through the structure from roof to dirt, than it is impervious surface. This includes decks, even if they have 1/8" or more spacing between the deck boards.
Just because water can run under the house, does not mean that it is not affecting the run-off of your lot. A house consentrates rain water into specific areas (drip lines) when it hits the roof and runs off. Unless you capture all the water from your roof and any decks, then dump it all into a leaching system, but I doubt that.
Having a house on piers does not count and make sure you do not have any gravel or crushed stone for anything on the property as those materials also do not count for a pervious surface.
