A. All improvements and site information, such as adjacent rights-of-way and property lines, shown on the landscape plan will be identical in size and location to those shown on the base plan (site plan or tentative plat). Should amendments be required to the base plan through the review process, the same amendments will be made to the landscape plan which will then be resubmitted along with the base plan.
B. The landscape plan will contain the following identification in the lower right corner of each sheet:
1. Legal description and address of site;
2. Cross-reference to:
a. Rezoning case;
b. Subdivision case;
c. Board of Adjustment case;
d. Design Development Option case;
e. Development Review Board (DRB) case; and/or,
f. Any other relevant case number for reviews or modifications that affect the site.
C. The name, address, and phone number of the individual who prepared the landscape plan.
Landscape plans submitted for review do not necessarily have to be complete working drawings ready for contractual work. However, all required landscaping and screening will be clearly shown in sufficient detail as to readily convey the intent to comply. Plans will include a planting plan, an irrigation plan, a grading plan, and construction details, each with applicable legend, key, symbols, sizes, quantities, and notes.
The following information must be provided on the plans. Information may be combined on one sheet if the combination of information does not obscure other details.
A. Planting Plan
1. Vegetation Plan and Schedules
a. The location of individual plants one gallon or larger in size and areas to be seeded, turfed, or planted from flats;
b. Sizes of plants indicated in boxes, gallon cans, or flats or by height (palms), number of canes (ocotillo), or number of pads (opuntia);
c. Ultimate size of plants indicated by the spread of canopy, circumference of shrubs, or spread of ground cover;
d. Both the proper and common name of each type of plant material. They should be included for any proposed seed list, if applicable;
e. Location, size, and name of existing vegetation to remain in place;
f. The location of oasis allowance area; and,
g. Material and areas of inert ground cover.
2. Calculations
a. Square footage of the site;
b. Square footage of the oasis allowance area and calculation;
c. Square footage of the vehicular use area; number of parking spaces, including the required and provided parking space calculations; and the calculation of the required number of canopy trees;
d. A shadow pattern and calculation are required in certain cases (see Section 7.6.4.B, Vehicular Use Area, of the UDC). Provide these, if applicable;
e. Minimum width and square footage measured from the inside edge of tree planters in vehicular use areas;
f. Length and width of landscape borders and landscape transition borders and number of canopy trees per length; and,
g. Square footage of all landscaped borders and calculation of the percentage of vegetative coverage, when applicable.
3. Screening
a. Location of screening elements;
b. Height of screening material and reference point for measurement;
c. Nature of screening material (e.g., permanent or temporary as in phased development); and,
d. Type of screening material (e.g., masonry wall, wood fence, species of plant material).
4. Maintenance Schedule
a. Pruning schedules to show that plant material will maintain pedestrian and vehicular clearances or that the material will establish opaque hedge screens, if required;
b. Replacement criteria, should plant material not survive;
c. Replacement or upkeep maintenance schedules for inert ground cover materials;
d. Upkeep maintenance schedules for exterior hardscape materials; and,
e. Maintenance and replacement schedules for irrigation systems.
B. Grading Information
1. Grade changes across the site indicated by one-foot interval contour lines or by spot elevations;
2. Percent slope across the site and the direction of the slope of paved areas;
3. Existing grades on adjacent rights-of-way and adjacent sites. If an adjacent right-of-way or site is under construction, show the proposed finish grades;
4. Extent of grading boundaries if a portion of the site is to be kept in its natural undisturbed state. Indicate natural contours of undisturbed areas;
5. Areas of detention/retention, depths of basins, and percentage of side slope;
6. The methods by which water harvesting or storm water runoff is used to benefit the oasis allowance area and other planting areas on the site; and,
7. Percent side slope of berms.
C. Irrigation Plan
1. Type of water conserving irrigation systems proposed and differentiation between systems for the different water use zones on the site;
2. Source of irrigation water;
3. Indicate potable or reclaimed water use. Reclaimed water system specifications, if used;
4. System specifications and system design and layout (Section 4-01.4.2, Irrigation , of the Technical Standards Manual);
5. Extent of supplementary irrigation in each planting area, provided by water harvesting methods;
6. Point of drainage off roof areas, amount of flow, and disposition of flow;
7. Temporary systems proposed to establish native seeded areas;
8. The length of irrigation duration (e.g., for native plat material, automatic drip for two years or until established); and,
9. The extent to which systems are proposed within the public right-of-way.
D. Construction Details
1. Materials and methods used to construct landscape planters;
2. Materials and methods used to construct plant guards and water diverters, such as curbs, bollards, or walls;
3. Materials and amounts necessary for inert ground cover;
4. Outdoor light fixtures;
5. Street furniture, outdoor art/sculpture, and water features;
6. Materials used for walkways and paving;
7. Grills or tree grates; and,
8. Planting details, method of caliche penetration, soil amendments, mulch cover, staking methods, and root barriers, if used.
E. Additional Information
1. Purpose and location of utility easements and facilities; and,
2. Locations of existing solar collectors on adjacent property.
This standard is established to assure that proper techniques are used in all aspects of conforming with the Section 7.7, Native Plant Preservation, of the Unified Development Code (UDC).
In accordance with Section 7.7.4.A, Submittal Requirements, a Native Plant Preservation Plan is required as provided herein.
Requests for exceptions from the Native Plant Preservation requirements in accordance with Sections 7.7.3.D.3 and .4 of the UDC are reviewed by the Planning and Development Services Department (PDSD). Submittals are required to document that the site does not contain, or the proposed project does not impact, Protected Native Plants. Submittal requirements shall consist of one or more of the following items:
3.1 An aerial photograph, taken within a maximum of three years of submittal, of the site at a minimum one inch equals 100 feet that delineates the site boundaries and clearly shows the absence of plants within those boundaries or a site plan that clearly shows that construction will not impact any plants. Any aerial photograph submitted, which was taken more than one year prior to submittal, shall be accompanied by a letter stating that the site is substantially unchanged from the date of the aerial photograph;
3.2 A signed statement from one of the plant professionals listed in Section 7.7.4.D, Professional Expertise, of the UDC who has visited the site and verified that Viable Protected Native Plants are not located on the subject site; or
3.3 Other documentation, acceptable to the PDSD Director, which clearly indicates that the site does not contain, or the project will not impact, Protected Native Plants. Such documentation includes, but is not limited to, photographs of the site taken from all sides of the property and a signed statement from the property owner that Protected Native Plants are not located on the subject site.
