Background
The property is previously received Hillside approval in 2017 and is currently being constructed. The latest update to the design has changed the brick at the south end of the garage to the vintage wood finish, the vintage wood finish at the entryway has changed to stucco, and the brick west of the pool has been changed to the split face stone finish.
Building Materials
Building materials shall include a stucco finish (Sherwin Williams Dovetail, LRV 26), a standard brick thin veneer (Solstice Stone Whinston, LRV 24), a vintage wood finish (Solstice Stone Mist, LRV 13), stone finish (Blue Hot Spur Split Face, LRV 32), a dark slate roof (Boral Roofing Saxony, LRV 10), and a matte black metal roof (Matte Black, LRV unknown). All material shall have an LRV of 38 or less.
Driveway
The driveway has changed from a round shape to a wider form with sharp turns. A driveway gate has been proposed 10’ behind the property line. Driveway materials shall include cobblestone pavers (Charcoal Gray, LRV <38), decomposed granite (Madison Gold, LRV not provided) and exposed aggregate concrete (LRV not provided). The driveway gate shall be powder coated black (LRV unknown) and shall be view fence. The gate columns and mailbox shall match in style. Columns shall have a gray stucco finish (Sherwin Williams Dovetail, LRV 26) with stone finishes (Blue Hot Spur Split Face, LRV 32).
Pool and Water Features
Two water features are provided at the entry to the residence. A side courtyard area includes another water feature, and the pool area shall have a walkway water feature. The pool and spa locations have been reconfigured but are located in the same general location.
Fencing
The applicant has increased the area and length of the pool fencing to create a larger courtyard. The pool fencing now extends across the rear of the property and no longer terminates at the end of the pool. The courtyard area created by screen walls in the rear yard will receive an increase in area. Mechanical equipment on the northeast side of the residence will receive a 4’ tall metal screen wall (Pantina, 38%).
Site Walls
The Grading and Drainage plans indicate that no retaining walls shall extend more than 6” above the grade. The rendered views however show walls extending past the 6” on the northeast and south west corners of the lot. The Hillside Development Regulations state that “walls may be solid walls provided they are of minimum height and length needed to screen the mechanical equipment, garbage cans, or windows of interior bathroom areas, and shall not exceed six (6) feet in height”. (Section 2207.VI.3)
Building Lighting
No new building light has been proposed.
Landscape Lighting
Landscape light shall include eight (8) tree up lights with a maximum output of 127 lumens (150 lumens allowable), ten (10) ground up lights, and twenty-one (21) down/step lights across the property. All light sources shall have a maximum color temperature of 3000K.
Landscaping
The property shall be landscaped with Ironwood, Mesquite, Palo Verde, Texas Ebony, Desert Willow, and Fruitless Olive tress. Shrubs shall include Desert Ruellia, Texas Ranger, Regal Mist, Valentine Emu Bush, Hummingbird Bush, Gold Mound Lantana, Japanese Boxwood, Bougainvillea Vine, and Green Cloud Sage. The remaining vegetation shall include Ocotillo, Agave Des, Blue Glow Agave, Golden Barrell, Red Yucca, Fire Sticks, Lady Slipper, Saguaro, Agave Americana, Green Desert Spoon, Mexican Fence Post, and Bi-Color Iris. All lawn areas shall use artificial turf.
Hardscaping
Hardscaping changes include the new cobblestone pavers (Charcoal Gray, LRV <38) at the driveway entry and front walkway area. The side yard walkway and pool area will receive cray pavers (Lucas Cantia, LRV 32). Trex decking (Gray, LRV 26) will be used in the rear courtyard area. A select amount of light colored pavers (Hot Spur Blue Honed, LRV 38) will be used at the front entryway and fire feature area. Pavers north of the pool area will be gray (Quarzo Gray, LRV 27). All material shall have an LRV of 38 or less.
Land Disturbance
The land disturbance has increased by 85 ft2 (22,519 ft2 - 22,434 ft2) when compared to the previously approved plans. The site will remain below the allowable disturbed area of 22,524 ft2.
Grading and Drainage
Grading and drainage associated with the construction of the property shall be modified to accommodate the newly proposed site layout. The retention basin located at the front of the property will be reduced in size and a larger retention basin in the rear yard shall replace a previously proposed bocce ball court. Two new driveway trench drains are proposed to carry stormwater off of the driveway. One trench drain shall direct stormwater into the smaller retention basin by gravity and the other to the rear retention basin via a sump pump system. Stormwater at the pool area shall be directed towards the southeast corner of the property and will then be carried over to the large retention basin via a sump pump system.
