How to Draw a Residential Site Plan for Yuma Az
§ 154-20.04 Required Landscape Areas.
(A)Single-family unit residential requirements.

(3) When the single-family residence is next to a tree chugalug with a width of at least eight feet, a minimum of ane street tree is required to be planted in the tree belt, and provided with a permanent irrigation arrangement.
(B)Requirements for all other zoning districts. Required landscape is classified into iv categories: perimeter, off-street parking, other areas, and retention basins, every bit outlined herein. Multiple categories tin apply to one property or parcel.
(a)Streetscape zone (including all streets surrounding a subdivision). Abutting all public street rights-of-mode shall exist a streetscape zone maintained exclusively as landscape areas with vegetation and hardscape materials measured from the back of curb for the first 20 anxiety or until the vertical plane of the building, whichever is less. The streetscape zone shall be calculated regardless of public rights-of-way or setback delineations. In residential districts, the streetscape zone is required for all streets surrounding a subdivision and any not-residential uses within the subdivision.
FIGURE 4: Streetscape Zone Examples
1.Trees. Street trees are required to be planted every 35 linear feet along the street right-of-way, as measured from the center of the trunk. Street trees shall be planted in accordance with the distribution and placement requirements of this article.
two.Shrubs. Along arterial and collector streets, shrubs are required at a rate of iv per required tree, except in certain pedestrian-oriented streetscape zones where shrubs may exist reduced.
iii.Groundcover. For all mural areas within the streetscape zone, colored landscape rock shall exist used as top dressing. Vegetative groundcover is permitted, but non required. For whatever area to be defended to the City of Yuma, no vegetative groundcover is permitted, just artificial turf is immune.
4.Building frontage/location.
i. If a building or structure is located ten feet or less from the back of adjourn, no trees are required and all areas located between the buildings and the back of curb must be either landscape or hardscape.
ii. If a edifice or structure is located at to the lowest degree ten feet from the dorsum of adjourn, trees are required along that street right-of-manner.
5. Special landscape treatment, may be required for Gateway and Historic/Scenic Routes every bit recommended in plans referenced in the General Plan.
(b)Medians. Median width is measured from the back of median curb to back of median curb. The minimum width for a landscaped median is eight feet.
one.Trees. Copse are allowed simply in medians with a width of 15 anxiety or greater, shall be planted at a charge per unit of one tree per 35 linear anxiety, and shall be located a minimum of five feet from the back of median adjourn. Species shall exist selected from the Recommended Plants List as approved for medians. Trees shall be located so that the expected mature tree canopy does not ultimately extend into the street right-of-way. Maintenance access shall also be considered in relation to traffic movement.
2.Shrubs. Shrubs shall not be required for medians, simply may be planted, with the approval from the city, within medians with a width of eight feet or greater. Mature size of the shrub shall be carefully considered to avoid eventual encroachment into the street.
3.Ground cover. Colored landscape rock shall be used as meridian dressing in all medians eight anxiety or wider. No vegetative footing cover or living grass is permitted, but artificial turf is allowed. Any portion of whatever median fewer than eight feet in width may exist treated with stamped concrete or other approved inert material.
(c)Screening between zoning districts. Required screening setbacks between residential districts and adjacent uses shall provide sufficient screening in order to mitigate the furnishings of potential nuisances such as dirt, litter, noise, heat, and glare of lights. The screening shall be equanimous of plant cloth and, depending on the zoning district, a vii foot loftier solid masonry wall.
ane.Trees. One per 35 feet (on center) of solid perimeter screening or subdivision wall; 15-gallon container (not-deciduous).
two.Shrubs. Ane shrub per 8 linear feet on center.
3.Rear, service side, and/or loading docks. Shall be screened from view by a masonry screening wall vii feet in acme.
iv.Screen row. A screen row of 15-gallon trees (non-deciduous) planted 25 feet on centre (or major fraction thereof), shall be provided along any lot line for a lot on which a residential structure greater than one-story in elevation is located with a lot line adjacent to any other residential construction.
(two)Off-street parking. Incorporating copse and shrubs in parking lots provides shade for people and cars, reduces the urban estrus isle effect, intercepts stormwater, improves aesthetics, improves air quality, provides visual screening, and creates a habitat for wild fauna.
(a)Mural within parking lots.
ane.Trees. For parking lots with eight or more spaces, 1 shade tree is required for every eight spaces or major fraction thereof. Trees shall be evenly distributed within the parking lot in tree wells with a minimum of fifty foursquare anxiety of pervious expanse, or, when tree wells are not possible, located within four anxiety of the perimeter of the parking lot. At a rate of one and a half per required tree, trees may be planted within five feet of the outer perimeter of the parking lot to meet this requirement. Trees required for other mural areas cannot exist double-counted to fulfill this requirement. Trees planted outside the perimeter of the off-street parking lot simply intended to count towards the requirements for off-street parking areas shall be conspicuously identified every bit such on the plan. Required trees may be eliminated for spaces located direct nether a covered parking canopy.
Effigy 5: Parking Lot Pattern Options
(b)Screening for off- street parking. On the exterior edge of an off-street parking lot containing xv or more spaces, a planting strip not less than five feet in width shall be provided parallel to whatsoever street rights-of-manner and planted with shrubs as specified below to achieve 80% visual screening with a minimal height of three and one-half feet at maturity. This screening may likewise include walls, but in no case shall a structure or shrub be placed within whatsoever visibility triangle for driveways or streets.
1.Shrubs. Minimum of i per eight anxiety (on center) of parking lot next to a public right-of-way.

Choose at least one choice from each category shown in Figure vi. These requirements apply just to basins not landscaped under some other requirement set forth in this code. For any portion of the memory basin that is side by side to a street, the landscape requirements for the streetscape zone shall exist applicable in addition to the requirements of this section.
