TRANSMITTAL DATE: August 9, 2021

COMMENTS: Please resubmit revised drawings and any redlined plans along with a detailed response letter, which states how all Zoning Review Section comments were addressed.

The proposed use is two (2) unit single family residential, which is permitted in the R-1 zone (minimum 10,000 sf lot size required), with use-specific standards 4.9.7.B.1 - .9, .11 applicable (UDC, Table 4.8-2).

01. COMMENT: Provide a site plan with the following information - https://www.tucsonaz.gov/files/pdsd/forms/Residential_Plot_Plan_Requirements.pdf

02. COMMENT: Provide the setback dimensions, both required and proposed. The required setbacks for the north, east and west parcel boundaries are 6' or 2/3 the height of the adjacent wall, measured from the property line to the exterior wall of the adjacent structure, the greater will apply. The required setback for the south parcel boundary is 25' per the subdivision plat (M&P, Book 7, Page 92).

03. COMMENT: It appears the casita is not meeting setback requirements. If this is the case, a neighbor waiver sign-off will be required to reduce the setback requirements. Copy the following language onto the site plan with the adjacent neighbors' signatures in the direction where the setbacks are not being met (2550 E La Madera Dr. and 2543 E Monte Vista Dr.)

"My Name is ________________ and I am the owner of the property located at ___________. I have reviewed the site plan and I have no objection to the structure being located or constructed ______ feet from the property line as depicted on the site plan."

04. COMMENT: The gross size of the lot is incorrect. Based on the subdivision map plat and the dimensions provided in this plan, the size of the parcel is 10,125 square feet or 0.23 acres, please correct this on the plans.

05. COMMENT: Provide a lot coverage calculation including all buildings, storage areas, and vehicular use area as a percentage of the total site.

06. COMMENT: Provide building elevations of the additions and the casita to determine setback requirements. The setback is based on the maximum height of the adjacent wall measured from grade.

07. COMMENT: Indicate all existing or proposed easements - there is a 5' utility easement along the northern parcel boundary per the subdivision plan (M&P, Book 7, Page 92).

08. COMMENT: Please submit the plans as one document for the next submittal.

City of Tucson Residential Plan Review
09/08/2021 SBLOOD1 ENGINEERING REVIEW Reqs Change 1. Until Floodplain Use Permit is issued engineering can't approve the building permit.
Outstanding issue on FUP:

This project site is mapped within a city of Tucson Estimated Flood Hazard Zone.
As per city code for a substantial improvement if a project site is within the floodplain - the sum of all improvements within any ten year period is limited to 50% of the value of the structure or the structure must be improved to floodplain standards (or verified that it is up to floodplain standards). According to pima county assessor's records the market value of the existing house is $ 152,750 (65% of most recent sale value of $235,000). That puts the proposed work of $90,000 at 58.9% which is over the 50% and therefore is classified as a substantial improvement. So you can either reduce the scope of the project, provide a higher appraisal of the house, or bring the house and proposed work to floodplain standards.
If you have any questions don't hesitate to reach out to me.
