04/22/2013 JASON GREEN ENGINEERING REVIEW Denied SUMMARY: Engineering Division of Planning & Development Services Department has received and reviewed the Site Plan (T13M02346) for the remodel of the garage into a sleeping quarter for the above referenced property and does not recommend approval of the Site Plan at this time.

The subject property is located within a mapped FEMA Special Flood Hazard Area Zone AE as shown on the Flood Insurance Rate Map (FIRM), Community- Panel No. 040073-04019C-1689L, effective date 06/16/2011. 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. Please note that as per the Substantial Improvement & Substantial Damage Rule: A Guideline for Permitting, dated October 2003 only one 3-foot wide doorway may be provided between the common wall of the existing structure and the new improvement. If more than one 3-foot wide linking doorway is proposed for the new improvement, and/or the improvements are determined to be substantial, then the entire existing structure and improved portions of the structure must be brought into compliance by elevation of the floors 1-foot above the regulatory flood elevation. In order to help you permit the addition we will need the following information from you.

1) Provide a Floodplain Use Permit Application with fees in order for PDSD to create conditions and track this improvement within the SFHA.

2) Provide a cost estimate, prepared by a licensed contractor or professional construction estimator, for the carport enclosure 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.

3) 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.

4) 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.

5) 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.
