Before moving a downspout in the City of Vicksburg, settle what will receive the water. A pipe below ground is not necessarily a storm drain, and an outlet that leads away from the house is not automatically an authorized destination.

The City sewer code distinguishes sanitary sewers, designated storm or combined sewers, and approved natural outlets. LSL’s decision path below turns those distinctions into questions for the proposal; it does not identify a private pipe or design a drainage system.

If the receiver is confirmed sanitary

Do not propose a roof-runoff connection to it. Section 23-123 prohibits roof downspouts and other listed surface-water sources from connecting to a building sewer or drain that reaches a public sanitary sewer, directly or indirectly. Section 23-137 separately prohibits roof runoff and other listed unpolluted water from discharge to a sanitary sewer.

For an existing suspected connection, ask the City and an appropriately qualified professional to establish what is actually connected and what correction is required. This article does not prescribe disconnection or excavation.

If nobody has identified the pipe or inlet

Mark the recipient unverified. A grate, curb opening, buried extension or low spot does not establish a sewer classification.

The MEMA/City flood guide, printed page 3, directs residents to ask public works whether their area has a combined or separate system. Take that question one step further for the proposal: ask which actual receiving feature the proposed outlet reaches and which records establish its classification. An area-wide answer alone does not trace a particular private pipe.

Use existing plans, records and safely visible surface features. Do not remove covers, enter a ditch or culvert, follow moving water, or open an unknown line to investigate. A missing record is a reason to resolve the proposal—not to guess.

If records identify a storm, combined or natural destination

Section 23-138 distinguishes sewers specifically designated as storm or combined from a natural outlet approved by the approving authority. Section 23-61 defines that authority as the City engineer or public-works director, or the designated representative described in the code. Ask the City who is acting in that role for the proposal.

Keep designation, ownership and any needed connection permission distinct. A ditch or creek can fit the code’s natural-outlet definition without establishing approval for this discharge. This guide does not settle easement rights, neighboring-property permission, capacity or additional project review.

The flood guide’s advice to direct downspouts away from the house is useful household context, not a separate approval of the nearest alternative outlet.

Make the destination part of the estimate

A quote ending at a downspout elbow and one including a buried route are different scopes. Compare bids on these terms:

  • Name the proposed endpoint and identify any unresolved receiving-system question.
  • State who will obtain the applicable classification, permissions or project review.
  • Separate included excavation/restoration from gutter work and explain what changes if the assumed destination cannot be used.

LSL’s proposal question is: “This price assumes discharge at [identified feature]. What confirms that recipient, what remains subject to approval, and what happens to the scope and price if it cannot receive this water?” Fill the brackets with actual information, not an invented approval.

At completion, retain the accepted route and relevant City response, and obtain safe surface photographs if useful. A later rain without visible ponding is not a capacity test or proof of legal permission.

Checked September 13, 2026: the cited code provisions in the August 14 online compilation, plus the flood guide’s cover and relevant checklist. The former March reference concerned the earlier compilation; LSL has not identified a new runoff rule merely from the version change. No outlet was inspected, flow calculated or connection approved.
