Site Engineering Review Comments:
1. This site is bounded by Houghton RD. This road can be found on the Major Streets & Routes plan and identified as a Scenic Corridor. As such, this site is covered by the Scenic Corridor Zone (SCZ). It is acknowledged that the General note required by this is provided:
a. Per UDC 5.3.4.A.1 and 3., “A buffer area 30 feet wide, adjacent to the MS&R future right-of-way line, is required and shall be preserved and maintained in its natural state…” and “The buffer area shall be restored as closely to its natural state as possible In areas where public safety or the delivery of public services precludes preservation of existing vegetation…” Draw, dimension, and label the 30-foot SCZ setback area on the site/grading plan.
b. UDC 5.3.4.C, describes permitted improvements within the SCZ setback area, Driveways or access lanes, if their area does not exceed 20% of the Scenic Routes Buffer Area (Buffer Area). In this instance, the width of the Buffer Area is 30 feet in accordance with Section 5.3.4.A.1. For the purposes here, the Buffer Area is calculated as follows: Multiply the distance of the property’s along the measured at the by 30 feet. If, due to topographical or engineering constraints, the or exceeds 20% of the Buffer Area, the width of the Buffer Area shall be increased to accommodate the square footage resulting from the following calculation: (Distance of the along the measured at the - total width of or ) x 24 feet = Required Buffer Area in square feet.
c. Ensure to update/revise all applicable details that show encroachment into the Scenic Buffer area.
2. ADA Grading note – Revise the keynote provided, the City of Tucson adopted The IBC 2024 with ICC A117.1 2017 edition at the beginning of 2026. This will need to be addressed across the plan set where IBC 2018 w/
3. Site plan and grading plan sheets – revise the plans to show and dimension the setback distance of the existing electric infrastructure from the proposed basin at the Northeast portion of the proposed development. This setback will have to be compliant to ensure no adverse impacts from the proposed infiltration area in regard to affecting the established towers and structures.
4. Regarding the CMU wall proposed directly north of water harvesting basin and west of the Lot 1 - When a wall is proposed within 5 feet of the horizontal location of the 100-year water depth, a report from an engineer registered in the State of Arizona shall be provided prior to approval of the construction permit that contains at least the following: a. The appropriate minimum setback from the top of slope; and b. Specific structural design requirements with details.
5. Revise/Update keynote 19 on sheet 8 – the clearance space for a double enclosure is required to be a minimum of 28ft X 40ft.
6. Pedestrian circulation is required to connect all buildings, dumpster areas, common areas, and the sidewalk on all the street frontages [TSM 7-01.3.3]. Demonstrate how this requirement is addressed for connecting the site to the proposed trash enclosure at the NE corner of the proposed site for lot 1.
7. Sidewalks shall be flood free for all storm discharges of up to and including a ten-year frequency flood event. Drainage flowing across all pedestrian circulation paths shall be conveyed under the path for up and including the ten-year frequency flood events, except at street intersections, pedestrian crossings, and PAAL pedestrian crossings [TSM 7-01.4.1.E]. This will need to be addressed regarding the SW side of proposed building on Lot #1 – a downspout (Keynote #34) is shown to be directly discharging on the concrete sidewalk at this section. Revise accordingly.
8. Provide a complete trash enclosure construction details in compliance with TSM 8-01.5.0. Details must address wall materials, wall height, gate type and swing, foundation, and enclosure dimensions. It is strongly encouraged that the figures presented in TSM 8-01.9.0 be used as the minimum basis for the enclosure and dumpster layout details shown on the plans.
a. If it is desired to proceed with the “Modified Dumpster Enclosure” as shown - Environmental services approval will be required in regard to accepting that they will have no issues with the proposed modified requirements. The current proposal shows the enclosure with finalized dimensions that differ from the standard double enclosure detail. The contact to reach out to at ES will be Andy Vera at Andy.vera@tucsonaz.gov. Please submit the approval provided for the resubmission of this development package.
b. If approval is provided, it will be necessary that a Technical Standards Modification Request (TSMR) be included in resubmission.

THE PROPOSED PLANS HAVE BEEN REVIEWED FOR COMPLIANCE WITH APPLICABLE DEVELOPMENT STANDARDS FOR SITE LANDSCAPE, NATIVE PLANTS, AND RAINWATER HARVESTING, PER-THE-CITY OF TUCSON UNIFIED DEVELOPMENT CODE (UDC), TECHNICAL STANDARDS MANUAL (TSM), AND ADMINISTRATIVE MANUAL (AM).

RESUBMIT REVISED DRAWINGS ALONG WITH A DETAILED RESPONSE LETTER, STATING HOW ALL SITE LANDSCAPE AND NPPO SECTION REVIEW COMMENTS HAVE BEEN ADDRESSED.

SITE LANDSCAPE/NPPO SECTION COMMENTS:

1. COMMENT: UDC 5.3.4 SCENIC BUFFER AREA: The 30-foot scenic buffer area is supposed to be revegetated with only native vegetation and laid out in a way that looks like the natural desert. With that being said per a conversation with site zoning, and similar projects along the same scenic buffer corridor, the scenic buffer can’t be used for drainage basins. An option would be to move the basin to the east 30 feet and leave the scenic buffer relatively flat with the naturalized plantings and hydroseeding. As always, I’m open to having a conversation about this issue. Please don’t hesitate to reach out to myself and/or the site zoning reviewer if you would like to discuss the Scenic Corridor Zone further.

2. On the rainwater harvesting plan, include a few of the spot elevations and drainage flowlines within the hardscape areas as shown on the grading plan for quick schematic reference.

3. Include a note on the rainwater harvesting plan to see the civil grading plan for drainage scheme and drainage structure implementation, e.g. curb cut detail.

4. Include a quick schematic detail or cross-section of one of the WHIA for general information. Mimic detail 1/grade transition and include plant placement, maximum slope, screened rock depth, depth of WHIA from hardscape flowline to top of screened rock, and anything else that you see fit for clarity for contractor and inspector quick reference during construction.

5. The irrigation pipe sleeves and the asphalt hatch are the same gray color, making the sleeves hard to see. Please update the line type or change the color of the asphalt hatch for clarity.

6. Prior to site landscape approval, ensure that Site Zoning and Site Engineering comments are fully addressed.

7. Include the Activity Number TD-DEV-0324-00092 on all sheets in the plan set.

Thank you.
