SITE PLAN REVIEW
A Site Plan Review is a formal evaluation process used by municipal planning departments to ensure that a proposed land development or construction project complies with local zoning codes, environmental regulations, and community design standards.
Unlike a building permit, which focuses on the structural safety of a building, a site plan review focuses on how the development impacts the land and its surrounding environment.
Key Objectives of a Site Plan Review
Towns and cities conduct these reviews to protect public health, safety, and community welfare. The process ensures that:
Zoning Compliance: The project respects building heights, setbacks, and density limits.
Safety & Access: Fire trucks, police, and ambulances can safely access the property.
Environmental Protection: Stormwater runoff, erosion, and wetlands are properly managed.
Neighborhood Harmony: The layout minimizes negative impacts (like glare from lights or loud noise) on neighbors.
What Does a Site Plan Include?
As a property owner, you will need to hire professionals (such as civil engineers, architects, or surveyors) to draft a highly detailed map of your property. A typical site plan features:
Element What It Shows
Property Boundaries Exact lot lines, easements, and current rights-of-way.
Structures Dimensions and locations of existing and proposed buildings.
Access & Parking Driveways, parking spaces, loading zones, and sidewalks.
Utilities Connections to water, sewer, electric, gas, and fire hydrants.
Grading & Drainage Elevation contours, stormwater retention ponds, and drainage pipes
Landscaping & Lighting Tree preservation, new plantings, buffers, and outdoor lighting positions.
The Step-by-Step Review Process
While exact timelines and rules vary by municipality, the general process follows these steps:
1. Pre-Application Meeting
Before submitting a formal application, you meet with planning staff. They will review your conceptual ideas, highlight potential deal-breakers, and explain exactly which local ordinances apply to your project. Skipping this step often leads to costly design revisions later.
2. Formal Submission
You submit the official application, the required number of site plan sets, environmental assessment forms, and the municipal review fees.
3. Inter-Departmental Review
The planning department forwards your plans to various municipal entities for specialized technical reviews:
Engineering: Checks stormwater, grading, and utility connections.
Fire & Police: Verifies emergency vehicle turning radii and hydrant access.
Highway/Traffic Department: Assesses traffic impact and driveway safety.
Water & Sewer Districts: Confirms system capacity to handle your project.
4. Public Notice and Hearing (If Required)
For larger commercial projects or multi-family residential developments, neighboring property owners are notified by mail. A public hearing is scheduled before the Planning Board or Zoning Board, allowing neighbors to voice support or concerns regarding traffic, noise, or privacy.
5. Decision and Conditions
The reviewing board or planning director will issue one of three decisions:
Approval: The plan is accepted as submitted.
Conditional Approval: The plan is approved only if you make specific changes (e.g., adding a specific fence type, planting more trees, or altering a driveway).
Denial: The project violates fundamental local laws and cannot move forward without a variance.
When Do Property Owners Need One?
You generally do not need a site plan review for minor cosmetic changes or simple interior renovations. However, you will likely need one for:
New commercial, industrial, or multi-family residential construction.
Major expansions or additions to existing commercial buildings.
Significant changes in land use (e.g., converting a residential home into a retail office).
Substantial changes to parking lots, grading, or clearing of large wooded areas.
