(2) 
To prevent inappropriate juxtaposition of industrial uses and residential uses.
(3) 
To provide effective sighting and controls on those uses which, by virtue of their size or external effect (noise, waste discharge, glare, fumes, dust, smoke, traffic generation and parking areas, etc.), could otherwise create nuisances or unsafe or unhealthy conditions.
Permitted uses and those uses requiring site plan review in all districts shall conform to all applicable specifications and requirements. A plumbing permit, building permit, occupancy permit and/or a special use permit shall be required for all buildings, uses and sanitary facilities according to the provisions of this chapter.
A. 
The maximum net residential density (i.e., the number of dwellings per acre, excluding roads) allowable for any division of land or for construction or placement of more than one dwelling unit on a single parcel of land shall be calculated on the basis described in the table below. For example, in developments where sewer service is not being provided, all of the well-drained and moderately well-drained land may be included in the density calculations, plus one quarter of the poorly drained land. Development on divided land shall not occur in percentages greater than those listed in the table below.

B. 
A high-intensity soil survey by a licensed soil scientist may be required by the Planning Board or Code Enforcement Officer.
A. 
Principal building. If more than one principal building is constructed on a single parcel of land, all dimensional requirements shall be met separately for each principal building.
B. 
Visibility at corner lots. All corner lots shall be kept free from visual obstruction for a distance of 25 feet measured along the intersecting street lines.
C. 
Minimum frontage. Must be on a street, an existing deeded right-of-way or a new deeded right-of-way with a minimum width of 50 feet. Lots which abut a street, an existing deeded right-of-way or a new deeded right-of-way with a minimum of 50 feet shall have frontage meeting the requirements of § 140-19 and shall comply with § 140-70H.
D. 
"Mixed use" means the development of a lot, building, structure or portion thereof with two or more different uses which cannot be accurately described as principal or accessory uses because none of the uses is clearly incidental and subordinate to another, or with a single operation, enterprise or activity which combines elements of two or more different uses and cannot be accurately described by one use definition. The determination that a mixed use exists or is proposed shall be made by the Code Enforcement Officer, subject to appeal to the Board of Appeals as an administrative appeal under § 140-76B. Mixed uses are allowed only under the following conditions:
(1) 
Each use must comply with all performance standards of this chapter applicable to that use.
(2) 
Where different dimensional requirements apply to the different uses, the more restrictive requirements shall apply to the entire mixed use.
(3) 
If any of the uses requires site plan approval, the Planning Board shall consider the impacts and effects of the entire mixed use when the Board applies the site plan approval criteria and when the Board determines what limiting conditions, if any, are required.
(4) 
Where there is any conflict or inconsistency between any of the standards of this chapter as applied to the different uses, the more restrictive standards shall govern the entire mixed use.
