Xeriscape Landscaping:
1. 
Xeriscape landscaping is an innovative, comprehensive approach of landscaping to promote water conservation. Xeriscape landscaping incorporates seven basic principles: planning and design, soil analysis, appropriate plant selection, practical turf areas, efficient irrigation, use of mulches and appropriate maintenance. These principles are explained below in the order a landscape planner or property owner would consider installing the best possible landscape. Each principle must be considered during the planning and design phase, as the sequence of installation is also very important is assuring a successful xeriscape.
a. 
Planning & Designing:
To get the look and function wanted while conserving water, create a landscape design. Draw the yard, including the locations of existing structures, trees, shrubs, and grass areas. Then, consider parts of the yard, how it should look, the amount of maintenance desired and the associated budget.
b. 
Evaluate soil and improve if necessary:
Soils can vary within a given site; an analysis based on random sampling can provide information for plant selection and soil amendments. The soils in North Texas range from clay to sand, and both are low in organic material. Whether clay or sand, the soil in your landscape will benefit from the addition of sphagnum peat moss, compost, aged manure or other decomposed organic materials. This will improve root development and water penetration and retention. Consult with a local nursery or County Extension Office on how to improve the soil before planting and installing the irrigation system.
c. 
Use appropriate plants:
Most plants have a place in xeriscape even those that have high water needs. Plant selection should be based on the plant's adaptability to the existing conditions present at the landscaped area and native plant communities particularly considering appropriate hardiness zone, soil type and moisture conditions, light, mature plant size, desired effect, color and texture. Plant species that are drought and freeze tolerant are preferred. Use of more plants with low water needs and native plants will allow the maximum water conservation. A list of approved plant material can be found in Appendix L in the "Tree Technical Manual: Arboricultural Specifications & Standards of Practice."
d. 
Create practical turf areas:
The type and location of turf areas should be considered a major design element of the landscape. The selection and location of turf should be decided on the same basis as other plantings, such as your purpose and function of the landscape. The reduction or elimination of high water use turf areas and locating them separately so that they may be watered more efficiently, can result in significant reductions in water use. Turf grass areas shall be consolidated and limited to those areas on the site that receive pedestrian traffic and provide for recreation use.
e. 
Water efficiently:
If an irrigation system is to be installed, it should be well planned and well managed. Turf areas should be watered separately. Group plants with like water needs, and water each group on separate zones. Not all plants need the same amount of water. Irrigation needs change with the season and the weather. Irrigate according to the needs of the plants rather than watering on a fixed schedule. Even plants used in xeriscape will require supplemental irrigation until they become established, which can take between two to three years.
f. 
Use organic mulch:
Mulch minimizes evaporation, reduces weed growth, slows erosion and helps prevent soil temperature fluctuations. Organic mulch such as wood chips or bark is best and although this mulch will decompose slowly over time, it will improve the soil by adding nutrients. The use of plastic is not recommended because it will cause organic mulch to slide or shift in location, preventing air and water from filtering into the soil, causing increased water runoff. Inorganic mulch, such as rock, should be used sparingly. Surrounding a home with rock will increase the temperatures, making the environment too warm for plants and people.
g. 
Maintain appropriately:
Proper pruning, weeding, and fertilization, plus attention to the irrigation system, will preserve and enhance the quality of xeriscape. A landscape adapted to the environment will require less maintenance, less fertilizer and reduce the use of pesticides and other chemicals.
*
Develop a general maintenance schedule
*
Reapply organic mulches once a year.
*
Mow when your grass is at the appropriate height, removing no more than one-third of the blade.
*
Learn best practices for mowing turf grass.
*
Fertilize your lawn, shrubs, and trees at the proper times and use the correct amount.
*
Check your irrigation system periodically to ensure it is operating efficiently.
*
Maintain your yard tools.
2. 
Any planned and maintained area that contains xeriscape plants must have visible physical borders around the boundaries of the permitted use accent areas. The physical borders of the permitted use accent areas must be sufficient in depth and height to maintain separation of xeriscape plants and turf grasses. It will be the responsibility of the land owner to keep xeriscape plants from growing or hanging over the borders in a manner that prevents visibility of the borders.
3. 
In order to reduce excessive water use, Xeriscape landscaping is encouraged. The total square footage of the required landscape area may be 100% xeriscape landscaping, if all landscaping materials are from the xeriscape landscaping approved list attached as Appendix L [not printed herein].
(c) 
Distance from overhead electric distribution lines.
(1) 
Large and medium trees must be planted a minimum of 30 feet (30') from the closest point of an overhead electric distribution line.

A landscape plan showing the plan of the street on both sides of each proposed drive/street to the proposed development with the grades, curb elevations, proposed street/drive locations, and all items (both natural and man-made) within the visibility triangles as prescribed below shall be provided with all site plans, if they are not on engineering plans that are submitted at the same time. This plan shall show no horizontal or vertical restrictions (either existing or future) within the areas defined below.
(b) 
Visibility Triangles–Defined.
No fence, wall[,] screen, billboard, sign face, tree or shrub foliage, berm, or any other item, either man-made or natural shall be erected, planted, or maintained in such a position or place so as to obstruct or interfere within the following minimum standards; however, on non-residentially zoned lots, a single pole for mounting a sign may be placed within this area provided the pole does not exceed 12 inches (12') in diameter, and provided every portion of the sign has a minimum height clearance of 9 feet (9'):
(1) 
Vision at all intersections which intersect at or near right angles shall be clear at elevations between twenty-four inches (24") and nine feet (9') above the top of the curb elevation, within a triangular area formed by extending the two curb lines from their point of intersection, for the following minimum distances for the applicable intersection, and connecting these points with an imaginary: line, thereby making a triangle. If there are no curbs existing, the triangular area shall be formed by extending the property lines from their point of intersection for a distance as prescribed below, and connecting these points with an imaginary line, thereby making a triangle as shown below.
(2) 
Intersection of Two Public Streets - the minimum required distance from the curb shall be 30 feet (30') and the minimum distance from the property line on streets without a curb shall be 20 feet (20').
(3) 
Intersection of a Public Street and an Alley - the minimum required distance measured from the property line shall be 15 feet (15'), or 25 feet (25') from street curb.
(4) 
Intersection of Private Drive and Public Street - the minimum required distance from the curb shall be 15 feet (15') and the minimum distance from the property line on streets without a curb shall be 10 feet (10').
