Lake, IN: Legal drains and subdivision review in Lake County

The Lake County Surveyor works with the Drainage Board on the legal drain system and reviews subdivisions in unincorporated areas. The office also maintains survey and mapping resources.

Remote plan-based takeoff support; no local office, completed local project or site investigation is represented by this page. Cost, delivery schedule and deliverables depend on the agreed project scope.

What this changes in the bid review

Estimating interpretation: A ditch visible on an aerial image does not establish its legal status, capacity or permission to receive discharge. Measure the designed outfall only after its location and approval responsibility are documented.

Check the project documents

Mark each item after reviewing its supporting document.Ask whether the receiving ditch or tile is a legal drain.Obtain the drain location and any applicable easement record from the responsible office.Separate subdivision drainage review from a proposed connection or crossing detail.

Clarification to request: Is the proposed outlet or crossing within a regulated drain and what approved detail applies?
