Background
The property currently contains a 4,990 ft.² residential property with two access points onto Indian Bend Rd. The home was constructed in 1973 and approximately 92% of the lot has been previously disturbed. This project went before the Hillside Building Committee on April 18, 2018. Residents in the area of the proposed project had concerns regarding potential noise from the negative edge pool and the neighbor directly behind the property had concerns with the overall height of the project.
New Single Family Residence
The proposed project will demolish the existing home and reconstruct the new single family residence consisting of approximately 6,320 ft.² (livable) including a small second level and view balcony. The property will be accessed from a single driveway onto Indian Bend Rd. as shown on the plans.
Pool
A negative edge pool is proposed to be located in the rear patio area facing Indian Bend Rd. Additionally, a patio seating area and fire pit is proposed beneath the pool area as shown on the plans.
Grading & Drainage
There will be grading associated with construction of the property to retain the “pre vs. post” stormwater volumes for the 100 year, 2 hour rainfall event. A retention basin will be located in the front of the house to collect stormwater runoff. A trench drain will be located near the end of the driveway to collect stormwater flows and divert it to a retention basin.
Sewer
The property is currently on a septic system. However, sanitary sewer is located within the vicinity of the property and property will be required to connect to the sanitary sewer if the cost to do so is less than 10% of the overall project cost.
Should the Hillside Committee wish to approve this application, staff suggests the following stipulations:
1. The Applicant shall submit a Construction Staging Plan to the Town per the Hillside Safety Improvement Measures and Process Manual for review and approval prior to being issued a building permit.
2. The Applicant shall submit a liability insurance policy for the proposed project in the amount of $2 million per occurrence and $5 million aggregate naming the Town of Paradise Valley as an additional insured prior to being issued a building permit.
3. The applicant shall submit a minimum of two quotes to run an 8”sanitary sewer across the length of the property frontage prior to being issued a building permit.
4. All construction parking shall be located on the property as much as possible. Any offsite parking shall be confined to the adjacent streets along the immediate property frontage. No construction materials will be allowed to be stored on the Town’s right-of-way;
5. No final approval or certificate of occupancy shall be issued until all hillside stipulations and all Town Code requirements are complied with, including, but not limited to, landscaping, fire flow, fire safety and all onsite and offsite improvements;
6. The limits of construction and proposed disturbed areas shall be clearly staked in the field, with visible roping, prior to and during construction and shall conform to the approved individual site analysis plan.
7. Noise from construction that can be heard off-site, including, but not limited to, hydraulic ram hammers, equipment used to cut through rock, machinery with audible back-up warning devices, powered machinery, truck delivery and idling, constant and persistent hammering, shall comply with Article 8-10, Nuisance Noise, as set forth in the Town Code.
