| 10/07/2015 | JASON GREEN | ENGINEERING | REVIEW | Reqs Change | DATE: October 7, 2015 SUBJECT: 309 N Medford Dr- Photovoltaic system to an existing nonconforming SFR REVIEWERS: Jason Green, CFM SUMMARY: Engineering Division of Planning & Development Services Department has received and reviewed the Site Plan and Floodplain Use Permit for the addition to the existing structure for the above referenced property and does not recommend approval of the Site Plan or Floodplain Use Permit at this time. The subject property is located within a mapped 100-year floodplain associated with the tributary of the Robb Wash. Any improvements to the existing structure are considered a substantial improvement to an existing floodprone structure if the value of the new improvement is 50% or more than the assessed/appraised value of the existing structure. In order to help you permit the PV system we will need the following information from you. 1) Provide a cost estimate, prepared by a licensed contractor or professional construction estimator, for the pv system showing fair market value of the material and labor. Please refer to the relative portions of the Handbook for Arizona Communities on Floodplain Management and the National Flood Insurance Program. 2) Provide an assessed or appraised value of the existing single family. The assessed or appraised value is for the structure only (excluding land value). The assessed value can be provided by the latest assessment rolls of the county assessor prior to the improvements being started or from a licensed appraiser. 3) If the cost estimate provided exceeds the 50% threshold then a hydraulic analyses performed by an Arizona Registered Civil Engineer is required to calculate water surface elevations and flow velocities during the 100-year flood event. The analysis must evaluate channel and over bank flow depths and velocities, and scour depths. The lowest finished floor elevation of the proposed enclosure and the single-family residence must be a minimum of one foot above the computed 100-year water surface elevation of the adjacent wash, evaluated at the upstream end of both of the structures. A site plan drawn to scale is needed showing the proposed building location, vertical datum used for calculating the water surface elevation, locations of hydraulic cross sections, floodplain limits, the lowest finished floor elevation for the proposed enclosure and single-family residence, and a detail of the foundation demonstrating that it is founded below the maximum scour depth. The site plan must be sealed by the engineer. 4) Cumulative values shall be accounted for the building structure, so that tracking of the 50% status is current. No person shall repair or alter property in a piecemeal manner so as to avoid the provisions of Section 26-4.1.a.3, Chapter 26-Floodplain and Erosion Hazard Management. GENERAL COMMENTS: Please provide a cost estimate and the assessed or appraised value of the structure that address the comments provided above. Include a comprehensive response letter addressing in detail responses to all of the above comments. If you have any questions, I can be reached at 837-4929.
