Large developments can affect roads, utilities, taxes, schools, and the environment. This page explains the basic record residents should look for.
A civic briefing from PennYanCitizens.com — applies to any large-scale development proposal in New York State.
When a large residential development is proposed, the approval process moves through multiple boards, multiple public hearings, and hundreds of pages of technical documents. Key studies are sometimes delayed, incomplete, or hard to find in the public record. Residents sometimes do not realize what is missing until late in the process — after key votes have already happened.
This page is a checklist. It lists the 16 types of studies and analyses that a complete public record should contain before a major project is approved. It is not a legal requirement that every project produce all 16 in the same form — but each one addresses a real question that affects residents, and the public should be able to find clear answers in the record.
This framework applies to large-scale projects (roughly 250 or more units), but most of these items — especially traffic, stormwater, utility capacity, and fiscal impact — are equally important for mid-size developments of 40 to 100 units. The scale changes; the questions do not.
Use this page as a checklist, not a verdict.

Knowing what to look for is only useful if you know when to look. Development review in New York typically moves through three stages. If you ask for a completed stormwater plan during the sketch plan phase, you will be told it is premature. If you wait until final approval, it may be too late to change anything.
Stage 1
The developer presents the general concept to the Planning Board. At this stage, the public record should show the basic project scope, site plan, proposed density, and the SEQRA environmental classification (Type I, Unlisted, or Type II). This is when the Board decides whether a Full Environmental Impact Statement is needed.
Stage 2
The substantive review phase. This is when the infrastructure studies, environmental analyses, traffic studies, and fiscal impact work should be completed, submitted, and available for public review. Most of the 16 items on this page belong at this stage. Public hearings typically happen here.
Stage 3
The Board votes to approve, deny, or conditionally approve. By this point, all studies should already be in the public record. If a study is still missing at final approval, residents should ask whether the Board voted to waive that requirement — and if so, what justification is on the record.
Residents sometimes direct questions to the wrong board. Here is which body typically has authority over each category of review in a New York village or town.
| Category | Typically Reviewed By | Why |
|---|---|---|
| Infrastructure & Utilities | Village/Town Board + DPW | Water, sewer, and electric capacity are municipal service questions — the governing board and public works department control them. |
| Site Plan & Traffic | Planning Board (+ NYS DOT for state roads) | Site plan review authority under Town Law §274-a or Village Law §7-725-a. Traffic on state highways requires DOT highway work permits. |
| Environmental (SEQRA) | Lead Agency (usually Planning Board) | The board designated as SEQRA Lead Agency makes the environmental determination. Often the Planning Board, sometimes the Village/Town Board. |
| Zoning Variances | Zoning Board of Appeals (ZBA) | If the project needs a variance from zoning code (setbacks, density, use), only the ZBA can grant it. |
| Fiscal / Tax / PILOT | IDA Board + Village/Town Board | Tax abatements and PILOT agreements are IDA actions under GML Article 18-A, but the affected taxing jurisdictions should review the fiscal impact. |
| County Review | County Planning Board (GML §239-m) | Projects within 500 feet of a municipal boundary, county road, state highway, or county-owned land must be referred to County Planning for advisory review. |

If you only have time to check three things, these are the ones with the most direct impact on your daily life, your taxes, and your commute.
1. Your utilities
Can the water and sewer systems handle hundreds of new households without overloading, raising rates, or requiring expensive upgrades that existing residents pay for?
2. Your commute
Has anyone studied what hundreds of new cars on the road will do to traffic, intersections, and road conditions — especially on state highways?
3. Your taxes
Will the project generate enough tax revenue to cover the new services it requires — roads, schools, police, fire, utilities — or will existing taxpayers absorb the difference?
The full 16-point framework is below. Each card explains what the study is, why it matters to you, and where the legal requirement comes from.
These studies answer: can the existing systems handle this project, or will it cost existing residents more?
Why it matters to you:
If the wastewater treatment plant is already near capacity, adding hundreds of new connections could trigger mandatory upgrades — paid for through higher sewer rates for everyone.
What it is:
An engineering analysis of whether the municipal sewer system and treatment plant can absorb the new flow without exceeding permitted discharge limits.
What to look for:
Current plant capacity vs. current flow (in gallons per day), projected new flow from the development, and whether the SPDES permit allows the increase.
Who produces it / who reviews it:
Produced by the developer's engineer. Reviewed by the municipal DPW and NYS DEC (which holds the SPDES permit).
Legal basis: NYS ECL Article 17; 6 NYCRR Part 750 (SPDES permits); Clean Water Act §402.
Why it matters to you:
If water pressure drops below fire-flow minimums, fire protection for the entire service area is compromised — not just the new development.
What it is:
Hydraulic modeling showing whether the water system can deliver adequate pressure and volume for both daily use and emergency fire suppression at the new site without degrading service elsewhere.
What to look for:
Fire flow rates (typically 1,000-1,500 GPM minimum), peak daily demand projections, and whether new storage tanks, pumps, or mains are required.
Who produces it / who reviews it:
Produced by the developer's engineer. Reviewed by municipal water department, fire department, and NYS DOH (which regulates public water systems).
Legal basis: NYS Public Health Law Article 11; 10 NYCRR Part 5 (public water supply); Ten States Standards; NYS Fire Code.
Why it matters to you:
Municipal electric utilities often have fixed low-cost power allocations (such as NYPA hydropower). If new demand exceeds those allocations, the municipality must buy power at market rates — and everyone's rates go up.
What it is:
An analysis of whether the local electric distribution system and power supply contracts can serve the new load without triggering rate increases or requiring infrastructure upgrades.
What to look for:
Current load vs. capacity, NYPA/NYMPA hydropower allocation limits, projected new demand in kW/kWh, and whether substation or distribution upgrades are needed.
Who produces it / who reviews it:
Produced by the developer's electrical engineer. Reviewed by the municipal electric utility and the governing board.
Legal basis: NYS Public Authorities Law (NYPA); NYMPA allocation agreements; local municipal utility charter.
Why it matters to you:
Hundreds of new households mean hundreds of new cars on roads that may already have congestion, sight-line issues, or substandard intersections. Every commuter on that corridor is affected.
What it is:
A Traffic Impact Analysis (TIA) modeling the effect of new vehicle trips on surrounding roads and intersections, including level-of-service ratings and any needed road improvements.
What to look for:
Projected daily and peak-hour trip generation, intersection level-of-service grades (A through F), and whether turn lanes, signals, or road widening are required.
Who produces it / who reviews it:
Produced by the developer's traffic engineer. Reviewed by the Planning Board and NYS DOT (for state highways — a highway work permit is required under Highway Law §52).
Legal basis: NYS Highway Law §52; SEQRA (6 NYCRR 617.2(b) — Type I thresholds); ITE Trip Generation Manual (industry standard).
Why it matters to you:
More households mean more collection runs, faster wear on DPW trucks and roads, and potentially higher tipping fees at the transfer station or landfill.
What it is:
An analysis of the solid waste and recycling impact — collection capacity, hauling frequency, transfer station throughput, and whether existing contracts or municipal services can absorb the increase.
What to look for:
Projected weekly tonnage, collection route impact, equipment depreciation, and whether the development will use municipal pickup or private hauling.
Who produces it / who reviews it:
Produced by the developer or their planner. Reviewed by municipal DPW and the governing board.
Legal basis: NYS ECL Article 27 (Solid Waste Management Act); 6 NYCRR Part 360 (solid waste regulations); local solid waste management plans.
These studies answer: what will this project do to the land, water, air, and character of the surrounding area?
Why it matters to you:
SEQRA is the single most important environmental protection in the process. If the review is incomplete or if the project is improperly split into pieces to avoid a full review (called "segmentation"), the entire approval can be legally challenged.
What it is:
The State Environmental Quality Review Act requires every government action — including development approvals — to assess environmental impact. Projects above certain thresholds (typically 250+ residential units, 10+ acres of disturbance) are classified as Type I, which carries a presumption that a full Environmental Impact Statement (EIS) is required.
What to look for:
The Environmental Assessment Form (EAF), the SEQRA classification (Type I vs Unlisted), the Lead Agency designation, the Positive or Negative Declaration, and — if required — the Draft and Final EIS. Also check whether the project was reviewed as a single action or broken into pieces.
Who produces it / who reviews it:
The applicant submits the EAF. The Lead Agency (typically the Planning Board) makes the determination. If an EIS is required, the developer prepares it and the Lead Agency reviews it.
Legal basis: NYS ECL Article 8; 6 NYCRR Part 617 (SEQRA regulations); 6 NYCRR 617.4(b)(5)(iii) — Type I threshold for 250+ residential units; 6 NYCRR 617.3(g) — prohibition on segmentation.
Why it matters to you:
Paving over farmland or open land eliminates natural absorption. Without proper engineering, stormwater runs off faster, causes flooding downstream, and carries pollutants into lakes and streams.
What it is:
A Stormwater Pollution Prevention Plan (SWPPP) showing how the development will manage runoff during and after construction to prevent flooding and water pollution.
What to look for:
Pre- and post-development runoff calculations, detention/retention basin design, erosion control measures, and compliance with the NYS SPDES General Permit for stormwater.
Who produces it / who reviews it:
Produced by the developer's civil engineer. Reviewed by the municipal engineer, NYS DEC, and — if in an MS4 area — the local stormwater management officer.
Legal basis: NYS ECL Article 17; SPDES General Permit GP-0-24-001; 40 CFR 122.26 (federal stormwater rule); local MS4 programs.
Why it matters to you:
If you live near a lake, reservoir, or classified stream, new development upstream can increase nutrient loading (phosphorus, nitrogen), harm water quality, and affect drinking water sources and recreation.
What it is:
An analysis of how additional wastewater discharge, stormwater runoff, and land disturbance will affect nearby water bodies — especially those classified as AA or A (drinking water sources).
What to look for:
Nutrient loading projections, water body classification (AA, A, B, C), proximity to public water supply intakes, and any watershed protection overlay zones.
Who produces it / who reviews it:
Produced by the developer's environmental engineer. Reviewed by NYS DEC and any applicable watershed protection commission or county health department.
Legal basis: NYS ECL Article 15 (Water Resources); 6 NYCRR Parts 700-706 (water quality classifications); Clean Water Act §303(d); local watershed protection ordinances.
Why it matters to you:
Converting farmland to housing is permanent. If the land is in a certified Agricultural District or classified as "Prime Farmland of Statewide Importance," the loss is not just local — it affects regional food production and the agricultural economy.
What it is:
A review of whether the parcel is within a NYS-certified Agricultural District, whether it carries a USDA farmland classification, and what notice requirements apply before converting agricultural land.
What to look for:
Agricultural District inclusion (Yates County Ag Districts are certified under AML Article 25-AA), USDA soil classification, NYS Department of Agriculture & Markets notice of intent, and any agricultural data statement filed with the municipality.
Who produces it / who reviews it:
Agricultural data statement filed by the applicant. Reviewed by the Planning Board. NYS Ag & Markets may review if the project triggers AML §305-a notice requirements.
Legal basis: NYS Agriculture & Markets Law Article 25-AA (§§300-310); AML §305-a (notice to Commissioner); USDA NRCS soil classification system.
Why it matters to you:
Construction on a large project can last 18 to 36 months. During that time, neighbors deal with noise, dust, blasting vibration, heavy truck traffic, and road damage. A mitigation plan sets enforceable limits.
What it is:
A plan specifying how the developer will manage construction impacts — hours of operation, truck routing, dust suppression, blasting protocols, erosion fencing, and a complaint resolution process.
What to look for:
Permitted work hours, designated haul routes (avoiding residential streets), noise and vibration limits, dust control commitments, and a named site contact for complaints.
Who produces it / who reviews it:
Produced by the developer's general contractor or project manager. Typically made a condition of site plan approval by the Planning Board.
Legal basis: Site plan approval conditions under Town Law §274-a / Village Law §7-725-a; SEQRA mitigation measures; local noise ordinances.
These studies answer: who pays, who benefits, and was the process followed properly?
Why it matters to you:
A development that sounds like growth can actually cost more in new services (roads, water, sewer, police, fire) than it generates in new tax revenue. Without a fiscal study, no one knows whether existing taxpayers will subsidize the project.
What it is:
A fiscal impact analysis comparing projected new tax revenue against projected new municipal service costs over 10 to 20 years.
What to look for:
Net fiscal impact (positive or negative), assumptions about assessed value, projected service costs by category (DPW, police, fire, schools), and whether the analysis accounts for any PILOT or tax abatement.
Who produces it / who reviews it:
Produced by the developer's fiscal consultant or economist. Should be reviewed by the municipal comptroller or finance officer and the governing board.
Legal basis: No single NYS statute mandates this, but SEQRA requires assessment of "growth-inducing aspects" and fiscal impact is a standard component of EIS scoping. Planning boards may require it as a site plan submission item.
Why it matters to you:
A project marketed as solving a housing shortage only works if the units are priced for people who actually live and work in the area. If the housing is priced above local wages, it does not serve the stated need.
What it is:
A market study analyzing local housing demand, wage levels, and whether the proposed units match the affordability profile of the local workforce.
What to look for:
Median household income vs. projected rent or sale price, vacancy rates, absorption rate (how fast units will fill), and whether the developer has made any workforce-housing commitments.
Who produces it / who reviews it:
Produced by the developer or their market analyst. May be reviewed by the IDA (if tax incentives are requested) or the Planning Board (if housing need is cited to justify the project density).
Legal basis: GML Article 18-A §858(4) (IDA must consider community benefits); HUD fair housing guidance; SEQRA population and housing impacts (6 NYCRR 617.2).
Why it matters to you:
New housing generates new students. If the school district is already at capacity, the additional enrollment can trigger facility expansions, staffing increases, and higher school tax levies — which affect every property owner in the district.
What it is:
A student generation analysis projecting how many new school-age children the development will produce, and whether existing school facilities and budgets can absorb them.
What to look for:
Projected student count (using standard multipliers by unit type), current school enrollment vs. building capacity, estimated per-pupil cost, and projected school tax levy impact.
Who produces it / who reviews it:
Produced by the developer's planner. Should be shared with the school district superintendent and board of education. The school district itself is not a reviewing agency for site plan approval, but its input matters.
Legal basis: NYS Education Law; SEQRA (student generation is a standard EIS component); Rutgers University student generation multipliers (industry standard).
Why it matters to you:
If the site contains buried archaeological resources or is near a historic structure, construction can permanently destroy irreplaceable heritage. State and federal law require investigation before ground is broken.
What it is:
A Phase IA (literature review and sensitivity assessment) and, if warranted, Phase IB (field investigation) archaeological survey, plus a review for proximity to National Register-listed or eligible historic structures.
What to look for:
OPRHP (Office of Parks, Recreation and Historic Preservation) correspondence, SHPO clearance letter, Phase IA/IB survey reports, and any determination of National Register eligibility.
Who produces it / who reviews it:
Produced by a qualified archaeologist (must meet Secretary of Interior standards). Reviewed by NYS OPRHP/SHPO and the SEQRA Lead Agency.
Legal basis: NYS SHPA (Parks, Recreation and Historic Preservation Law §14.09); National Historic Preservation Act §106 (for federally funded/permitted projects); SEQRA (cultural resources are a required review area).
Why it matters to you:
When an Industrial Development Agency (IDA) grants a PILOT (Payment in Lieu of Taxes), the developer pays reduced property taxes for a fixed period — often 10 to 20 years. The difference is revenue that local taxing jurisdictions (village, town, county, school district) do not collect. Residents should know how much is being given up and what the community gets in return.
What it is:
An analysis of the PILOT agreement terms, the total foregone tax revenue over the PILOT period, and the cost-benefit justification the IDA used to approve the incentive.
What to look for:
The PILOT schedule (year-by-year payments vs. full-tax equivalent), total foregone revenue, the IDA's cost-benefit analysis, the public hearing record (required under GML §859-a), and whether affected taxing jurisdictions were consulted.
Who produces it / who reviews it:
Produced by the IDA staff or the developer's financial advisor. The IDA board votes on the agreement after a public hearing. Affected taxing jurisdictions (village, town, county, school district) should review but do not have veto power.
Legal basis: NYS GML Article 18-A (§§850-888); GML §859-a (public hearing requirement); GML §874 (PILOT agreements); NYS Authorities Budget Office (ABO) reporting requirements.
Why it matters to you:
Even if every technical study checks out, the approval can be overturned in court if the legal process was not followed — improper SEQRA classification, skipped public hearings, failure to refer to County Planning, or segmentation of the environmental review.
What it is:
A process integrity check verifying that the reviewing boards followed the required procedures at each step — proper notice, proper environmental classification, proper referrals, and proper public hearing conduct.
What to look for:
Was the project classified correctly under SEQRA (Type I vs Unlisted)? Was it reviewed as a single action or segmented into pieces? Were public hearings properly noticed? Was the GML §239-m County Planning referral made? Were all required findings adopted in writing?
Who produces it / who reviews it:
This is not a document the developer produces. It is the reviewing board's own procedural record. Residents can verify it through meeting minutes, resolutions, and FOIL requests.
Legal basis: 6 NYCRR 617.3(g) (segmentation prohibition); GML §239-m (County Planning referral); Town Law §274-a / Village Law §7-725-a (site plan procedure); CPLR Article 78 (judicial review of agency action).
Important note about waivers
Planning boards have the legal authority to waive certain submission requirements if they determine a study is not necessary for a particular project. If you cannot find one of these studies in the public record, the first question to ask is: "Did the Board vote to waive this requirement, and if so, what is the justification on the record?" A waiver is not automatically wrong — but it should be documented, voted on, and justified in the meeting minutes.
You do not need to be a lawyer or an engineer to use this checklist. Start with the basics and work from there.
What is being built? Where? How many units? Who is the developer? Which board is reviewing it? You can usually find this on the Planning Board agenda or in the public notice for the hearing.
Go through the 16 items above. Which ones can you actually find in the public record — on the municipal website, in meeting minutes, or in documents available at the clerk's office? Mark what you can find and what you cannot.
Missing is not always a problem — some studies may not apply, or the Board may have granted a waiver. But a missing study is a signal to ask questions, not to ignore.
If something important is not publicly available, you have two options: file a FOIL request with the municipal clerk, or ask the reviewing board directly at a public meeting where it can be found.
At the microphone — what to say
If you attend a public hearing and a study you expected to find is not in the record, you can put this on the official transcript:
"I respectfully request the Board hold open the public hearing until the [name of study] is completed and available for public review."
This is a polite, procedurally appropriate request. It creates a record entry that the Board must respond to. You do not need to be an expert to say it.
We applied this 16-point framework to the proposed 500-unit development on Route 14A in the Town of Milo and Village of Penn Yan. The result is a card-by-card audit showing which studies the public record contains — and which it does not.
See the Route 14A development review →Under New York's Freedom of Information Law (FOIL), you have the right to request any record held by a government agency. If a study referenced on this page is not available on a municipal website, you can request it by name from the clerk's office.
