Allen, IN: Allen County regulated drains are not only open ditches
The Allen County Surveyor describes regulated drains that include open ditches, tile drains and urban drains under the Drainage Board. The office also reviews drainage, plats and erosion-control matters for unincorporated development.
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 buried tile conflict can add a crossing structure or change a utility profile even when no ditch appears on the site plan. Keep unresolved drain locations in the clarification register rather than assuming uninterrupted trench runs.
