01/25/2022 PIMA COUNTY ENGINEERING REVIEW Reqs Change Review by Pima County. Contact Loren Makus at City of Tucson PDSD for questions about these comments.

Drainage Report Comments:
1. The adjacent "DOCK-HI INDUSTRIAL" development (Chamberlain Group?) has significantly altered the historic drainage patterns entering the project site from the east, and the discharges could be different from what was shown on the tentative plat excerpts included in the report. Obtain the drainage report and plans for this development and discuss their findings in the report. Provide these reports and plans. Any third party drainage reports used in this project's drainage report must be incorporated into this project's drainage report and verified as accurately representing peak flow based on current standards; otherwise prepare an independent hydrologic analysis of offsite conditions.

2. The existing condition watershed delineation for watershed "SOUTH" cannot be used as the allowable outflow for developed conditions (excluding the critical basin 85% adjustment). The northwesterly area of this watershed is not draining to the existing culverts under Commerce Center Place. Revise the watershed delineation, and adjust the allowable outflows used for detention basin analyses.

3. Provide PCHydro analyses for the catchment area map included in the drainage report. There appears to be an issue with the watershed analyses. For example, RD-A north is shown to have a Q100 of 7.68 cfs, however a brief check of PCHydro calculations for this watershed is showing 9.6 cfs, or about 25% more than what is being reported. This increase could be interpreted as small for only this one small watershed, however the total increased flow into the detention basins could increase by 10-15 cfs if the same error was made on all of the watersheds.

4. Provide a culvert analysis of the 2'X8' CBC utilizing any tailwater condition created by the existing downstream culverts under Commerce Center Place. Discuss the headwater condition at the inlet and demonstrate no increases in water surface elevations on the adjacent property.

5. Some of the stage storage discharge tables from PCRoute are missing from the printouts in the report where runoff is routed through outlet structures. Provide additional printouts. Provide printouts of the stage-volume sheet of PCRoute.

6. Provide energy dissipation calculations for all storm drain outlets and culvert outlets, including the 2'X8' CBC. While the CBC capacity must be checked using tailwater conditions, the velocity protection should be checked conservatively as a free outfall. Velocities > 10 fps will require to be wire tied. HEC-14 procedures can be used for sizing energy dissipation.

7. Assess the inlet headwater condition for the existing culverts under Commerce Center Place, and use this headwater as a tailwater condition for the detention basin routing if applicable.

8. Provide overflow weir velocities for the basins or provide erosion protection on the plans.

9. Manholes are required at all junctions, bends larger than 10 degrees, and where pipe diameters change. Provide hydraulic analysis of the storm drain networks using pressure flow calculations, and include tailwater conditions and minor losses at all junction and bends. Check the addition of total flow in the network; it appears that the flow from CB 220 was not added?

10. Provide hydraulic analysis of the capacity of all catch basins and curb openings.

11. Revise all basins to show a maximum retention ponding of 9". Retention depth is defined as retained runoff in the basin from its lowest point to an outlet invert 9 inches above the bottom. Revise the Water Harvesting Area table in the report to show the provided volume is only for 9" depth.

12. Discuss the maintenance and inspection requirements for the stormwater conveyances and detention basins on the project site. Provide an inspection checklist.


Construction Plans comments:

1. Construction note 9 is missing from sheet C2.4. Constriction notes are missing from sheet C1.6. Check all sheets for construction note callouts and revise as necessary.

2. Angle point for 2'X8' CBC has inverts labeled as 24"? Are there storm drain laterals at this location? Provide clarification. The proposed 2'X8' CBC does not provide easy maintenance access. Provide a junction structure at the bend for maintenance access.

3. Label all slopes on basins. Provide erosion protection slope treatment for all basin slopes steeper than 3:1.

4. Check plans for consistency between the report, grading plans and details. For example, the overflow weir for the northeast basin is modeled as 10' wide in report, but shown as 19' wide on sheet C1.1, and 20' wide on detail 5 of sheet 2.7. Revise plans to reflect the drainage report.

5. Provide cross sections of basin overflow weirs to show how they are graded to the top of the basins.

6. Provide detention basin security barriers for any basin with a Q100 water surface elevation deeper than 2 feet.

8. Show the thickness of the underside of the CBC on detail 2 on sheet 2.7 and label the clearance provided between the bottom of the CBC and the top of the 18" storm drain. Label the 18" storm drain pipe material. Clarify structural protection of the 18" storm drain. Label the Q100 and headwater elevation on the profile.

9. Manholes are required at all junctions, bends larger than 10 degrees, and where pipe diameters change. Revise plans.

10. Provide weir elevations on details on sheet C2.7. Show Q100 WSE. Check for discrepancies between the report's HWE and the details. For example, detail 4 on sheet C2.7 shows a water depth of 2 feet, which is accurate for the retention depth, however the 100-year water surface elevation is 2.3 feet per the report, and the freeboard should be revised accordingly. Provide cross section details for all of the basins. Show bottom and top elevation, weir erosion protection if necessary, and tailwater elevation if applicable.

11. Label the Q100 at all structures. Label all basins as private. Provide additional labels on the plans for the basins including the top elevation, Q100 water surface elevation, Q100 in, Q100 out, first flush retention volume, detention volume, and freeboard.
