| 08/27/2008 | JASON GREEN | ENGINEERING | REVIEW | Denied | DATE: August 27, 2008 SUBJECT: 802 W Calle Francita- Enclosure of a carport to an existing single-family residence TO: Victoria Aguilar LOCATION: T15S R13E Sec11, Ward 1 REVIEWERS: Jason Green, CFM ACTIVITY: T08CM02643 (Site Plan) and T08OT01838 (Floodplain Use Permit) SUMMARY: Engineering Division of Development Services Department has received and reviewed the Site Plan (T08CM02643) and Floodplain Use Permit (T08OT01838) for the enclosure of the existing carport 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 City of Tucson Flood Hazard Area as shown on the Flood Hazard Maps associated with a tributary of the Mission Park 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. 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 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 attached to the hard copy of this letter and plans. 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.

This letter reflects comments to be addressed. In order to facilitate a shorter back check time, we request that you please provide revised plans and calculations, highlighting any changes, along with a written response to each of the noted items indicating action taken. SCOPE OF REVIEW: The scope of this plan review covers architectural, plumbing, mechanical, energy conservation and electrical. All code references are to the 2006 International Residential Code, 2006 International Energy Conservation Code. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet, conditions and concerns before permit approval.

To avoid delays, ensure that all corrections have been made, are complete, and have been coordinated on all applicable detail and note sheets (clouded revision notation is not necessary for comment changes). All engineers and architects involved in the design of the structure are to seal the related sheets of plans, details and calculations in accordance with the rules of the State Board of Technical Registration. Construction drawing guidelines are available from the residential desk of the Development Services Division. The City of Tucson adopted the 2006 IRC with amendments on 6/12/2007, the 2006 UPC with amendments on 7/10/2007 and effective 1/1/2007 the Inclusive Home Design. All plans should reference these codes.
