What should Flower Mound homeowners know before building a backyard?
Flower Mound has real elevation change on a lot of its lots. Grade is the first thing we solve — retaining and drainage, then the pool, then everything that sits around it.
This is Cross Timbers ground — sandier loam sitting on clay. It digs more kindly than the black prairie further east, but the sand drains onto clay that does not, so grading and drainage get solved before a single stone is set.
In Flower Mound the job is reviewed by the Building Inspections Department, and we file and follow the permit through that office ourselves. Flower Mound requires a permit for any in-ground pool, for an above-ground pool deeper than 24 inches, and for hot tubs and spas.
Longhorn has built across Denton County and the wider Metroplex since 1984. We prepare the drawings an HOA typically asks for, and every project starts with a free design visit and a firm price.
