02/07/2025 Site Engineering REQUIRES RESUBMIT Comment response letter is from a previous review cycle. The following comments must be addressed:
1. Provide a detail for the 1.25' deep detention basin including side slopes, stabilization method, and inlet/outlet design. Provide drawdown calculations or routing hydrographs and ensure the basin will drain within 12 hours.
2. Per DSSDR 4.13.3: Providing first flush retention underground is prohibited, without prior approval of the Floodplain Administrator. The drainage report states that infiltration is poor in this location. No drawdown calculations have been provided. The proposed retention volume is roughly 4 times the required amount based on the calculations in the drainage report. If you wish to proceed with underground retention, floodplain administration shall be added to the next review cycle and you will need to provide a narrative explaining how the requirements of DSSDR 4.13.1 Underground Storage Standards are fully met. It is strongly recommended to remove underground retention from the plans.

SECOND REVIEW

This plan has been reviewed for compliance with applicable development criteria in the City of Tucson Unified Development Code (UDC) Administrative Manual (AM) Section 2-11 and Technical Manual (TM) Section for landscape, native plants, and water harvesting.

Please resubmit revised drawings along with a detailed response letter, which states how all Landscape/NPPO Review Section comments are addressed.

SITE LANDSCAPE/NPPO SECTION COMMENTS:

1. Color construction documents are not appropriate. Update all of the plans in the CD set to be monochromatic (black, white and gray).

2. Update all notes in the plan set that say to see sheet D1 for future ROW and SVTs. The notes should read see sheet D2.

3. On the rainwater harvesting plan, show simple spot elevations (bold numbers) at the inlets, bottom of WHIAs and outlets for simple reference for the contractors and inspectors.

4. Add drainage flow line arrows on the hardscape and within the WHIAs. Add notation referencing curb cut inlets and outlets, downspouts and splash pads, and associated sidewalk scuppers. All of this information should be shown on the grading plan and needs to be replicated on the rainwater harvesting plan.

5. Double check the subwatershed and WHIA correlation. Example: Subwatershed (S-6) is related to WHIA 5 on the plan and in the water demand spreadsheet subwatershed (S-7) is called out in the column related to WHIA 5. This is occurring in other places on the plan as well.

6. The plan would be easier to read and review if the WHIA and Subwatershed numbering had direct correlation to each other. Example: WHIA 1 and S-1, WHIA 2 and S-2, etc.

7. Check dams or weirs appear to be proposed within the north and south WHIAs. Adjust tree locations so that they are not in the middle of the check dam. Label all check dams on all plans in the set. Provide high point elevations for the check dams and low points at the bottom of the associated WHIAs.

8. The west street landscape border requires 4 trees. Currently the plan only shows 2 trees, and those 2 trees are being double counted as part of the north and south interior landscape borders. There are SVTs to contend with. Maybe add two additional trees in the southwest corner WHIA?

9. The parking lot trees adjacent to the building on the south side are located in a very narrow planting area. Can a tree planting curbed diamond/or curbed triangle be added to give the trees more space to grow.

10. Is section D-D on the east property line? Add the D-D cross-section line on the plan view.

11. Add a unique line type that represents root barriers wherever trees are within 5’ of paved surfaces/hardscape. Add leader call outs or keynotes for the root barrier line work, and in the call out refer to the root barrier detail.

12. Remove the PRELIMINARY stamp that is over the Architects seal on all plan sheets in the set prior to approval. Also, remove the red color.

13. Indicate the poly sleeve in-between the planter areas south of the building parking area.

14. Add irrigation lines and sleeves to the planter islands in the parking area to the north of the buildings.

15. Trees and shrubs require different amounts of water. Trees and shrubs need to be on separate valves, thus requiring a dedicated tree poly line and a dedicated shrub poly line. Add the separate lines to the irrigation plan.

Thank you.
