[Ord. No. 849 § 415.2, 10-16-2007]
Maximum density is measured as the number of dwelling units per acre of land and is measured by dividing the number of dwelling units on a lot or parcel by the parcel's net area (in acres), except in Town House Residential District which shall utilize the gross area of the lot or parcel.
[Ord. No. 849 § 415.3, 10-16-2007]
In general, intersecting streets, determining block lengths, shall be provided at such intervals as to serve cross traffic adequately and shall not exceed six hundred (600) feet in cul-de-sac neighborhood. Pedestrian ways and/or easements through the block may be required to serve nearby public facilities. Such pedestrian ways shall have a minimum width of six (6) feet and paved full width.
[Ord. No. 849 § 415.4, 10-16-2007]
Lot area is measured as the net amount of contiguous land area (except for Town House Residential) contained within the property lines of a lot or parcel, not including streets or rights-of-way, floodways, wetlands, ponds or slopes in excess of twenty percent (20%) for new lots. No zoning or building permit or development approval shall be issued for a lot that does not meet the minimum lot requirements of these regulations except that the minimum lot area standards of these regulations shall not prohibit the construction of a detached dwelling unit on a lot that was legally platted or recorded before the adoption of these regulations, provided that the dwelling unit is constructed in compliance with all applicable dimensional standards and meets the minimum health and safety standards for water and wastewater facilities and private sewage disposal systems.
[Ord. No. 849 § 415.5, 10-16-2007]
Lot width is measured between side lot lines along a line that is parallel to the front lot line at the front setback.
[Ord. No. 849 § 415.6, 10-16-2007]
Street or lot frontage is measured between side lot lines along the front lot line.
[Ord. No. 849 § 415.7, 10-16-2007]
A. 
The Board of Aldermen, upon recommendation of the Planning and Zoning Commission, is authorized and empowered to establish, regulate and limit and amend, by ordinance, building or setback lines from the existing or planned future right-of-way for streets, stream corridors or public improvement as shown on the major street plan and to prohibit any new structure being located within such building or setback lines.
B. 
Setbacks are measured between the furthermost projection of a structure and the nearest property line of the lot on which the structure is located. Setbacks must be unobstructed from the ground to the sky except as specified in this Chapter. The setback of the structure from front, side and rear lot lines shall be measured at right angles from the lot line to the nearest point of the adjacent structure wall. The following features may encroach into the required setbacks of residential districts:
1. 
Landscaping and light fixtures;
2. 
Flagpoles, fire escapes, mailboxes, fences or walls, driveways, curbs and sidewalks;
3. 
On-site sewage disposal (septic) systems, and underground utilities;
4. 
Signs not greater than four (4) square feet in area and authorized under these regulations;

[Ord. No. 849 § 415.8, 10-16-2007]
A. 
A structure shall not be constructed across the property line(s) of two (2) or more contiguous lots. However, if the placement of a proposed structure would otherwise cross the property line of two (2) or more contiguous lots held by the same owner, prior to the issuance of a building permit, the property owner must apply for and receive a voluntary lot merger or lot line adjustment to move or eliminate the property line in question. The lot line adjustment process only may be used if the resulting parcels will comply with lot development standards of the land use district in which the parcels are located.
B. 
Lots that are adjoining and held in common ownership, or under the control of the same owner, shall be treated so as to conform so far as possible with the minimum area requirement of the zoning district in which they are located. No lot so merged, or portion thereof, may be changed or transferred in any manner that will increase the degree of non-conformity unless a special permit has first been obtained from the Board of Adjustment. No such special permit may create any additional buildable lot(s).
[Ord. No. 849 § 415.9, 10-16-2007]
For any building on a lot or parcel abutting a single-family residence, the building setbacks must be increased by at least one (1) foot for each foot of height in excess of thirty-five (35) feet.
[Ord. No. 849 § 415.10, 10-16-2007]
All structures hereafter designed or erected and existing structures which may be reconstructed, altered, moved or enlarged shall not exceed the maximum structure coverage regulations of the district in which they may be located. Lot coverage is measured as the percentage of the total lot area covered by structures and other impervious surfaces. It is calculated by dividing the square footage of impervious surface by the square footage of the lot.
[Ord. No. 849 § 415.11, 10-16-2007]
All buildings or structures shall comply with the height regulations pursuant to these regulations.

2. 
Values in Exhibit 415-B are subject to the correction factors listed in Exhibit 415-C. If the noise is not smooth and continuous, one (1) or more of the corrections which follow shall be added or subtracted from the applicable decibel level given in Exhibit 415-B.
