Excellent spot to build on a quiet cul de sac. Very nice new construction is being built just a few houses down. There is a house next door to this lot and evidence of potential utilities already in place in the cul de sac a couple of lots down. No time limit as to when to build, or no restrictions on who to build with, and you can enjoy the amenities while designing and building your new dream home. Enjoy life by the lake - a small lakeside community with access to Lake Travis, a playground, pool, tennis, and more! The property is approx. 1 mile to Emerald boat ramp, which is private for LVPOA members. Survey available and buyer to verify all build requirements, utilities, floodplain, and restrictions.
