A. 
In order to maintain the high quality of Clayton's residential neighborhoods and commercial districts and assure the compatibility of new development, a site plan review process is hereby established. A site plan is an accurate, legible drawing which is drawn to scale and clearly depicts the dimensions and angles of the lot boundary lines, landscaping, contours, drainage flow, location of trash and HVAC units, impervious coverage and any existing and proposed improvements to the property.
B. 
The purpose of the site plan review process is to provide for a review of:
1. 
A project's compatibility with its environment and with other land uses and buildings existing in the surrounding area.
2. 
The quantity, quality, utility, size and type of a project's required open space and proposed landscaping improvements.
3. 
The ability of a project's traffic circulation system to provide for the convenient and safe internal and external movement of vehicles and pedestrians.
4. 
The type and location of parking provisions.
5. 
The quantity, quality, utility and type of a project's required facilities, where applicable.
6. 
The location and screening of a project's air-conditioning units and other associated equipment.
7. 
The location, adequacy and screening for trash.
8. 
The location and adequacy of a project's provision for drainage and utilities.
9. 
The promotion of public safety and benefit to the general welfare, as evidence that the project is in compliance with good planning practices and principles.
10. 
A project's impact will not overtax public utilities, services or other municipal facilities.
[Ord. No. 5814 §1(10.2), 4-27-2004; Ord. No. 6191 §5, 2-28-2012; Ord. No. 6802, 1-24-2023]
A. 
The requirements of this Section shall apply to the review of all site plans meeting the following parameters:
1. 
Principal Uses — Residential. Site plan review will be required for all new residential construction within all residential zoning districts. Site plan review is also required for large residential additions within residential zoning districts, where the total square footage of the proposed addition is fifty percent (50%) or greater than the total square footage of the existing principal structure. Site plan review may also be required for conditional use permits and other residential additions within residential zoning districts when, in the judgment of the Director of Planning and Development Services, the location of the property and/or character of the proposed conditional use or addition are such that site plan review would be advisable.
2. 
Principal Uses — Commercial. Site plan review approval shall be required as a condition to receiving a building permit involving new construction or substantial renovation to buildings or structures over ten thousand (10,000) square feet for all principal uses permitted by right in all commercial zoning districts located in the City of Clayton. Site plan review may also be required for conditional use permits and other commercial additions within commercial zoning districts when, in the judgment of the Director of Planning and Development Services, the location of the property and/or character of the proposed conditional use or addition are such that site plan review would be advisable.
3. 
Accessory Structures. Site plan review may be required, at the discretion of the Director of Planning and Development Services, for all (commercial and residential) accessory structures whenever such structures exceed twenty-five percent (25%) of the total square footage of the existing principal structure.

4. 
Accessory Uses. Site plan review may be required, at the discretion of the Director of Planning and Development Services, for accessory uses, such as accessory dwelling units, whenever such uses occur within a detached accessory structure.
5.
