§ 25-243. Parish-wide land use overview.

Within the hurricane protection levee system, unused land (thirty-nine and ninety-five hundredths (39.95) percent) and residentially developed land (thirty-two and seventy-two hundredth (32.72) percent) accounted for almost seventy-three (73) percent of all land use in Jefferson Parish. General sales or service was next at six and nineteen hundredths (6.19) percent, followed by manufacturing and wholesale trade at four and sixty-two hundredths (4.62) percent.

Counting only land inside the levees, the West Bank has nearly seventy-one (71) percent of total land in Jefferson Parish. Comparing the parish wide distribution of development, the East Bank has slightly more than half of the residentially and commercially developed land in Jefferson Parish, while the West Bank has the majority of developed land in all of the remaining land use classifications. Almost all, ninety-six and eighty-eight hundredths (96.88) percent, of the unused land within the hurricane protection levee lies on the West Bank.

The following table indicates land use within unincorporated Jefferson Parish.

* Does not include land outside of the Hurricane Protection Levee.

Parish-wide, nearly ninety (90) percent of all residential development is single-family. Multi-family is second with four and nine tenths (4.90) percent, two-family at three and twenty-eight hundredths (3.28) percent, and four-family with one and eight tenths (1.80) percent. The remaining residential classes each account for less than one (1) percent of residential land use. Comparing the East and West Banks, residential development accounts for fifty-nine and twenty-six hundredths (59.26) percent of East Bank development, while on the West Bank just under twenty-three (23) percent of land is developed residentially. Counting only the developed land on both the East and West Banks increases the West Bank residential ratio to forty-eight and twenty-two hundredths (48.22) percent of developed land.

Table 4.2: Residential Land Uses and Density—Unincorporated Jefferson Parish

	Acres	% of Parish	Units	Net Density
Single-Family	15.867.73	89.66%	94,036	5.93
Single-Family Townhouse	56.53	0.32%	740	13.09
Two-Family	580.02	3.28%	7,660	13.21
Three-Family	41.25	0.23%	534	12.95
Four-Family	285.15	1.80%	6,280	22.02
Multi-Family	866.88	4.90%	28,504	32.88
Total	17,697.56	100%	134,659	7.61

 

Looking at net residential density, the East Bank is developed at an average of eight and sixty-nine hundredths (8.69) units per acre, while the West Bank is developed at six and eight tenths (6.80) units per acre. Single-family has the lowest density parish wide, with multi-family having the highest. Single-family densities are similar on both the East and West Banks; however, the more intense residential uses, four-family and multi-family, have significantly higher densities on the East Bank.

(Ord. No. 21939, § 1, 8-6-03)

Note— Net density for residential land was calculated by dividing the total number of acres devoted to that use. Since the amount of land used for roads, drainage, or any other public rights-of-way were not included, the calculation yields the net density for each use.
