Understanding Sewer and Water Concurrency: A Comprehensive Guide
In real estate development and property acquisition, "concurrency" refers to the legal requirement that the necessary public infrastructure—specifically water supply and sewage treatment capacity—is available to support a proposed development or property use at the time the impact occurs. Verifying concurrency is a critical due diligence step; failure to confirm that a property has adequate utility service can result in stalled projects, denied building permits, or significant additional costs to extend infrastructure to your site. This article outlines the essential steps to verify sewer and water concurrency for residential and commercial properties.
Steps to Verify Utility Concurrency
- Consult the Local Utility Provider: The most direct method is to contact the local municipal water and sewer department or the private utility company serving the area. Request a "Letter of Availability" or a "Utility Capacity Verification." These documents formally confirm whether the existing lines serving the property have the capacity to handle your intended use.
- Review Zoning and Comprehensive Plans: Municipalities often have long-term plans that dictate utility expansion. Reviewing the local government’s comprehensive plan can help you understand if the property is located within a planned service area or if you are responsible for extending infrastructure, which is a major capital investment.
- Check for Existing Tap Fees and Impact Fees: Even if a line runs in front of the property, you must determine if those utilities have been "paid for" via impact fees. If a developer or previous owner never paid the connection fees for a vacant lot, you may be liable for substantial impact fees before you can pull a building permit.
- Assess Infrastructure Condition: For older properties, verify the current state of the lines. Sometimes a property is "concurrency-approved" based on older municipal standards, but the physical pipes may require an upgrade or replacement to meet modern building codes.
- Engage a Civil Engineer: For complex projects or vacant land acquisition, hire a civil engineer to perform a feasibility study. They can provide a detailed analysis of the flow requirements versus the current capacity of the municipal system and identify any necessary off-site utility improvements.
Expert Tip: Always ask the utility provider for a "Will Serve" letter. This is a formal, written commitment from the utility company stating that they have the capacity to provide water and sewer services to the site. Having this document in hand is often a requirement for securing construction financing and final building permit approval.
Key Takeaways
- Due Diligence is Mandatory: Never assume that because a utility line exists in the street, you have the right to connect to it. Capacity limits are real and enforced.
- Verify Fees Early: Impact fees for water and sewer can reach tens of thousands of dollars. Include these costs in your initial pro forma or budget.
- Documentation Matters: Always secure written verification from the utility provider; verbal confirmation from a representative is generally not legally binding.
- Proximity Isn't Capacity: A main line may be close to your property, but if the downstream treatment plant or pump station is at maximum capacity, your project could face a moratorium.
