1) New Survey Cost on a Vacant Ono Island Lot

• Boundary survey (standard residential lot): $1,200 to $3,500
• Boundary survey (waterfront, irregular, dense vegetation, or complex corners): $2,500 to $6,000
• Boundary + topographic survey (most common for build planning): $3,500 to $9,000
• Elevation certificate (if needed for financing or flood documentation): $150 to $600

• Lot size and whether corners are readily accessible
• Waterfront features, bulkheads, and shoreline complexities
• How much brush-clearing is needed to shoot lines
• How clear the deed history and prior pins/monuments are
• Whether you need topo contours, tree shots, or a buildable-area overlay
• Turnaround time, rush fees, and required signatures or certifications

If the lot is being purchased for new construction, I usually recommend a boundary + topo survey so your architect, builder, and permitting team are all working from the same “ground truth” data.

2) Water Distribution Plan Pricing

This can mean anything from a simple utility layout for a single home (meter location and service line routing) to a stamped civil engineering plan showing waterline sizing, tie-in points, valves, backflow, fire flow considerations, and coordination with the utility provider. The price depends on how complex the site and connection are.

• Simple single-lot water service layout: $1,500 to $4,000
• Stamped civil “utility plan” for permitting (water, and sometimes sewer): $4,000 to $12,000+
• If the lot requires extending or upsizing a main line: planning and engineering can move higher, and construction costs are separate

• Distance to the nearest main and complexity of the tie-in
• Whether the plan must be stamped by a licensed engineer
• Whether fire flow or hydrant spacing must be addressed
• Coordination requirements with the utility provider and permitting office
• Need for combined water + sewer drawings, grading, and erosion-control sheets

Many single-home builds only need a clean site plan that shows utility locations and service runs. If an engineer-stamped water distribution plan is required, it’s typically because of connection complexity or permitting standards tied to the scope of work.
