Background
The property previously contained a 2,600 ft2 residential property with an attached carport constructed in 1960. The structure was demolished in 2019.
New Single Family Residence
The proposed project shall construct a new single-story residence with approximately 5,000 ft2 of livable area. Existing disturbed areas are also proposed to be revegetated to blend in with the natural desert.
Pool
A pool and water feature are proposed in the north side of the property. A tall water feature (accessory structure) is proposed at the end of the pool.
Materials
Proposed exterior finishes are stucco and block with natural earth tones. Pavers and tiles are proposed for the hardscape surfaces (driveway, walkways) and the water feature. The provided dark gray paver (LRV 12), light gray paver (LRV 25), and “silver” tile (LRV 35) samples meet Hillside requirements. Stucco walls shall be painted tan (Dunn-Edwards, Ash Gray, DEC 751, LRV 35). CMU walls, veneers, and a water feature shall consist of gray blocks (integral color, LRV <38). The standing seam roof, metal fascia, trellis structures, metal garage doors, guardrails, and gates shall be painted black (Dunn-Edwards, “Custom” Black, LRV 10). All material shall have an LRV of 38 or less.
Building Lighting
The building light includes five (5) proposed wall sconces with a maximum output of 1000 lumens (750 lumens allowable) and 16 recessed can lights with a maximum output of 630 lumens (150 lumens allowable). All light sources shall have a maximum color temperature of 3000K.
Landscape Lighting
Landscape lighting will include five (5) up lights with a maximum output of 135 lumens (150 lumens allowable) and six (6) step lights with a maximum output of 240 lumens (250 lumens allowable). All light sources shall have a maximum color temperature of 3000K.
Landscaping
Areas west of the residence shall be revegetated with native desert plants. An existing palm tree shall be removed, and an existing Saguaro shall be relocated to south of the residence. The site will include new plants including Silver Torch Cacti, Golden Barrel Cacti, Firestick Cacti, Deegrass, and Ocotopus Agave. All lawn areas shall use artificial material.
Land Disturbance
The building pad slope of 6.00% allows a disturbance of 60.00% of the lot. The applicant has proposed a disturbance of approximately 81.35% (33,724 ft2), which is less than the existing 94.32% (39,100 ft2). The original driveway off of N Lauretta Lane will be removed and the area will be restored back to natural grades.
Grading and Drainage
There will be grading associated with the construction of the property in order to properly retain the “pre vs post” storm water volumes for the 100-year, 2-hour rainfall event. The property will be graded in a fashion that all onsite stormwater will ultimately flow towards a retention area on the northeast corner of the lot. Offsite flows will be routed to Lauretta Lane and the natural wash located on the northeast corner of the property.
Sewer
A new septic system is proposed for the property. No sanitary sewer exists in the near vicinity of the property.
Hillside Safety Improvement Plan
The Applicant submitted a Hillside Safety Improvement Plan in accordance with the Hillside Safety Improvement Measures and Process Manual per Section 5-10-9 of the Town Code. The plan completed 45 days without any public comment. Staff commented on the placement of the retention basin and routing of offsite drainage.
