Morrisville Unified Development Ordinance - June 2017

Article 11: Interpretation and Definitions Section 11.4. Measurement, Exceptions, And Variations of Intensity and Dimensional Standards 11.4.1. Measurement

E. Lot Coverage Lot coverage (expressed as a percentage of lot area) shall be determined by measuring the total horizontal land area (in acres or square feet) covered by all solid surfaces (hard surfaces and buildings) on the lot, dividing that coverage area by the lot area, and multiplying the result by 100.

F. Structure Height The height of a structure shall be determined by measuring the vertical distance from the mean elevation of the finished grade at the base of the front of the building up to:

The highest point of the deck line for a flat roof; The mean height level between eave and ridge for a gable, hip, cone, gambrel, or pyramid roof;

The deck line of a mansard roof; or

The highest point of a shed roof. (See Figure 11.4.1.F: General Height Measurement.)

(Ord. No. 2015-002, 04/29/2015)

G. Setback

Generally Front, corner side, side, and rear setbacks on a lot shall be determined by measuring the horizontal distance along a straight line extending at a right angle from the lot’s front, corner side, side, or rear lot line (as appropriate) to the foundation of the nearest structure on the lot. (See Figure 11.4.1.B: Lot Dimensions.) The area defined by a minimum setback and the lot line from which it measured is a required front, corner side, side, or rear yard (as appropriate). Allowable encroachments into required yards shall be ignored when measuring setbacks (see Section 11.4.2.D, Allowable Encroachments into Required Yards).

Front and Corner Side Setbacks

a. Corner Lot (1) On a corner lot, the front and corner side setbacks shall be measured—and the minimum front and corner side setback requirements applied—from the front or corner side lot line, as appropriate. (2) On a corner lot where the intersecting right-of-way boundaries are defined by a radius, the front and corner side setbacks shall be measured—and the minimum front and corner side setback requirements applied—from the front or corner side lot line, as appropriate,
