How much does it cost to build a pond in Virginia?

There is no honest single price for a pond in Virginia. We found no current, dated Virginia price source from a government agency, so this page does not quote one, and a figure from a marketplace or blog would not tell you what your site costs. What a pond costs is set by the ground, the size, the permits and the engineering, and the only reliable number is a written quote for your lot.

What drives the cost

How much soil moves. A pond is mostly an excavation job. Depth, surface area and whether the soil is dug out, built up into an embankment, or both set the machine hours. What happens to the spoil matters too: soil spread on site is cheaper than soil trucked away.

Soil and water retention. Some soils hold water well and some leak. If your ground will not seal on its own, the contractor may need to bring in or treat material, which adds cost. A test pit or soil investigation before pricing is a good sign.

The dam and spillway. An embankment pond needs an outlet. For a dam that falls under Virginia's rules, "the spillway capacity shall perform at a minimum to safely pass the appropriate spillway design flood",^[1] and that takes engineering. The regulation says "an impounding structure shall be regulated if the impounding structure is 25 feet or greater in height and creates a maximum impounding capacity of 15 acre-feet or greater, or the impounding structure is six feet or greater in height and creates a maximum impounding capacity of 50 acre-feet or greater, unless it is otherwise exempt".^[1] Most backyard ponds are far smaller, but the larger and deeper the water, the more design the dam needs.

Permits and plans. Fees and requirements are set locally. Montgomery County, for example, says "a land disturbing permit is required when disturbing more than 10,000 square feet of land",^[2] and that "an erosion and sediment control plan must be submitted to the County Engineer for review and approval".^[2] The county also lists ponds among agricultural engineering operations that do not need that permit, but only "ponds not required to comply with the Dam Safety Act".^[2] If the pond affects a stream or wetland, federal permitting can apply as well; see whether you need a permit to build a pond in Virginia.

Access and site. Equipment has to reach the spot. A tight gate, a steep lot, trees to clear or a high water table all add time. Tree and brush clearing is often priced separately; see what clearing a wooded lot involves.

Finish work. Seeding or stabilizing the banks, an overflow channel, inlet piping, fencing and any liner or edging are extras that some quotes include and others leave out.

Getting a quote you can compare

The Board for Contractors advises that "it is advisable to get at least three written bids or estimates using identical plans and specifications so you can compare prices and contractors".^[3] It also warns: "Beware of any bid substantially lower than the others."^[3] On a pond, a very low bid often leaves out the spillway, the erosion control or the permits.

Ask each bidder to state in writing:

• the pond's dimensions, depth and the volume of soil to be moved
• who designs the embankment and spillway, and whether an engineer's drawings are included
• who applies for permits and pays the fees
• how spoil soil, topsoil and the banks are handled
• what happens if the ground will not hold water, and who pays

On deposits, the Board's checklist says: "Limit your deposit to 10% down or $1,000, whichever is less."^[3]

Call before anyone digs

Before any excavation Virginia law is clear that "no person shall make or begin any excavation or demolition without first submitting a locate request to the notification center".^[4] Make sure your contractor does it, and read the 811 rules for digging in Virginia.

When to call a licensed pro

For the whole job. The Board for Contractors says that "if the work you are considering is valued at $1,000 or more, a valid Virginia Contractor’s License is required for the license category in which the contractor is to work".^[3] Class C covers a single contract over $1,000 but less than $30,000, Class B covers $30,000 or more, but less than $150,000, and Class A covers $150,000 or more.^[5] Check the licence before you pay anything, and see how a pond is built so you know what a complete quote covers.
