| 07/05/2012 | JASON GREEN | ENGINEERING | REVIEW | Denied | DATE: July 10, 2012 SUBJECT: 1011 N Van Alstine St- Engineering Review TO: Alex Enoch LOCATION: T14S R13E Sec11 Ward 1 REVIEWERS: Jason Green, CFM ACTIVITY: T12CM02749 SUMMARY: Engineering Division of Planning & Development Services Department has received and reviewed the site plan application (T12CM02749) and Floodplain Use Permit (T12OT00991) 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 AO1 per the Flood Insurance Rate Maps 04019C2276L the following information is required prior to site plan review: SITE PLAN: 1) DS Sec.2-01.3.3: Revise the site plan to list the DDO Case # adjacent to the title block in the lower right hand corner of the plan. List any conditions of DDO approval if applicable. 2) DS Sec.2-01.3.7: Clarify the Grading Notes on the site plan, Sheet C1.0. The grading notes reference HDZ conformance for construction and not the required Grading Notes that should apply to this project. Remove all notes that reference HDZ since this property does not fall under HDZ review. Provide the correct notes as referenced in the comments below. 3) DS Sec.2-01.3.7: Call for a Pre-construction meeting prior to start of earthwork. To schedule a PDSD Pre-construction meeting, SWPPP inspection or general Engineering Inspections, call IVR (740-6970), or schedule with a Customer Service Representative at the Planning Development Services Department, or contact PDSD Engineering at 791-5550 extension 2101, or schedule inspections online at: http://www.ci.tucson.az.us/dsd/Online_Services/Online_Permits/online_permits.html 4) DS Sec.2-01.3.7: Provide a general note stating that all proposed fencing and walls will require a separate permit for review and approval by all necessary Planning Development Services Departments. Any proposed walls or fencing will be reviewed for compliance with Chapter 26 Floodplain and Erosion Hazard Ordinance, a separate Floodplain Use Permit will be required for any new wall or fence permit for the subject property. 5) DS Sec.2-01.3.7.B.2.a: Revise the site plan to provide a note that states; "This project is affected by the City of Tucson Floodplain Regulations, subject property is located within a mapped FEMA Special Flood Hazard Area Zone AO1 per the Flood Insurance Rate Maps 04019C2276L." 6) DS Sec.2-01.3.7.B.2.b: Revise the site plan to provide a note that states; "Elevation Certificates are required for the new single family residence and must be returned to the City of Tucson Planning & Development Services Department, Engineering Section for conformance review prior to the pouring of the 1st slab and prior to the final inspection." Both a Prior to Slab and a Prior to Final hold will be placed on this permit for the single family residence until the required Elevation Certificates are returned and show conformance with the set conditions. 7) DS Sec.2-01.3.8.C: Revise the site plan document to include all information regarding the existing public right-of-way for Van Alstine St. Label the width, type and dimensioned width of paving and existing curb (or shoulder), label the center line of the road. 8) DS Sec.2-01.3.8.C: Revise the site plan to label Van Alstine St as a "Public Road." 9) DS Sec.2-01.3.9: Revise the site plan to remove the symbol marked as "Ignore" that references a stair way ramp landing. Remove this symbol from the site plan for clarity. 10) DS Sec.2-01.3.9.M: Revise the site plan to correct the limits of disturbance as shown on Sheet C1.0. The limits of grading should state 1,510 not 1.510, revise. 11) TC Sec.26-5.2.5: Revise the site plan to provide drainage vents within the bottom 1-foot of the proposed CMU wall to prevent encroachment into the SFHA and to alleviate adverse impacts to surrounding properties and right-of-way. Clearly Keynote the vent locations and provide a detail to show construction, the vents must be located in the new portion of the wall every 5-foot off center and must provide a clear 6-inch x 12-inch opening to prevent hydrostatic pressures and encroachment within the SFHA. Or provide a Drainage Report with encroachment calculations and required venting design. 12) TC Sec.26-5.2.9: Since the subject property is located within a mapped regulatory floodplain, it will be required that 2 elevation certificates for the proposed single family residence be filled out by an Arizona Registered Land Surveyor showing that the lowest finished floor of the proposed single family residence and the service facilities are elevated to or above the RFE, and returned to our office. The first elevation certificate must be returned to this office prior to the pouring of the slab. The second elevation certificate must be returned to our office prior to the certificate of occupancy. 13) TC Sec.26-5.3: Revise the site plan and all associated cross sections to clearly label and dimension the method of elevation and all construction aspects for the proposed single family residence. Clearly dimension stem wall design along with the required openings in the proposed crawl space. Per the proposed method of elevation (FFE elevated on a stem wall with a open crawl space under the floor) the Elevation Certificates that are required must reflect a building design in conformance with Building Diagram #8 on the Elevation Certificate Instructions. An "opening" is a permanent opening that allows for the free passage of water automatically in both directions without human intervention. Under the NFIP, a minimum of two openings is required for enclosures or crawlspaces. The openings shall provide a total net area of not less than one square inch for every square foot of area enclosed, excluding any bars, louvers, or other covers of the opening. A window, a door, or a garage door is not considered an opening; openings may be installed in doors. Openings shall be on at least two sides of the enclosed area. If a building has more than one enclosed area, each area must have openings to allow floodwater to directly enter. The bottom of the openings must be no higher than one foot above the higher of the exterior or interior grade or floor immediately below the opening. For more guidance on openings, see NFIP Technical Bulletin 1. GENERAL COMMENTS: Please provide the revised site plan and all associated details that address the comments provided above.
