Site Engineering Administrative Comments:
1. Provide the development package case number, TD-DEV-1225-00310, adjacent to the title block on all sheets.
2. Provide the Zoning and Land Use General note: “The developer, any successors and assigns, will hold the City of Tucson, its officers, employees, and agents harmless from any and all claims for damages related to the use of this development as shown hereon, now and in the future, by reason of flooding, flowage, erosion, or damage caused by water, whether surface flood or rainfall.” AM 2-06.4.7.B.1
3. Provide the Zoning and Land Use General Note: “Drainage will remain in its natural state and will not be altered, disturbed, or obstructed other than as shown on this site plan.” AM 2-06.4.7.B.3
4. Provide the Zoning and Land Use General Note: “No structure or vegetation shall be located or maintained so as to interfere with the sight visibility triangles in accordance with Section 10-01.5.0, Sight Visibility, of the Technical Standards Manual.” AM 2-06.4.7.C.2
5. Provide the Zoning and Land Use General Note: “Any relocation or modification of existing utilities and/or public improvements necessitated by the proposed development will be at no expense to the public.” AM 2-06.4.7.D
6. Provide the Zoning and Land Use General Note: “This project is designed to meet the Overlay zone(s) criteria, UDC Article 5.4 Major Streets and Routes Setback Zone (MS&R) and UDC Article 5.5 Gateway Corridor Zone (GCZ) AM 2-06.4.7.A
7. Provide the Zoning and Land Use General Note: “Any wastewater discharged into the public sanitary sewerage system shall meet the requirements of Pima County Ordinance No. 1991-140, as currently amended.” AM 2-06.4.7.E.3
a. I would suggest referring to Administrative Manual 2-06.4.7 General Notes – and going through each required note/detail that may be required for proper formatting/content presentation.
8. Provide a construction detail for the perimeter fencing/wall.
Pedestrian Circulation and Parking Area Comments:
9. Provide dimension call outs for sidewalks on the site plan (G1.0).
14. Provide Accessible parking sign construction detail. Note to show the required minimum height to be 7 feet minimum. This is required when the ADA sign is placed within a pedestrian pathway. TSM 7-01.4.3.B. It can be less when not within a pathway.
10. Wheel stops will be required at all parking spaces adjacent to the sidewalks so as not to reduce the sidewalk path to less than 4 feet. UDC 7.4.6 Sidewalks that are 6 and a half feet or wider will not require adjacent parking spaces to have wheel stops. This will need to be demonstrated for all parking spaces along the Building A’s North side.
11. In reference to Detail 2 on sheet 4 (G2.0), wheel stop curbing must be a minimum of two and one-half feet from the front of the parking space. UDC 7.4.6.H.3
12. Pedestrian circulation is required to connect all buildings, dumpster areas, common areas, and the sidewalk on all the street frontages per TSM 7-01.3.3. Demonstrate how this is achieved to connecting street frontage along Palo Verde RD and Brosius Ave.
13. Provide Sight visibility triangles for all the site entrances, along Valencia RD and Palo Verde RD in compliance with TSM 10-01.5.0. NOTE: Valencia RD is designated as an Arterial RD & Palo Verde RD is designated as a local RD. These designations will be used for Table 5.3
14. On the Site plan (G1.0), provide a keynote and call-out for to clearly show downspouts and sidewalk scuppers. to ensure that stormwater from roof drains, up to and including flow from the ten-year storm event, does not pass over sidewalks per Technical Standards Manual 7-01.4.3E.
15. Portions of certain Land Use Classes which by their nature will not be used for public pedestrian access, such as industrial uses, commercial storage uses, wholesale uses, contractor yards, or similar uses, are not required to have sidewalks constructed in conformance with this standard, provided adequate pedestrian refuge areas are provided. TSM 7-01.3.B.2 This is in reference for both the west and east sides of building A, demonstrate adequate pedestrian refuge areas.

Waste Management comments:
16. Revise Trash enclosure detail A on sheet 6 (G2.2) to be consistent with the standard detail figure found in TSM 8-01.9.0 Figure 3A. This includes showing the required minimum clear space of 24’-8” and 10’-4” respectively as well as proper bollard placement/spacing.
a. 6” concrete slab rather than 5”
b. Revise trash enclosure detail and grading plan (C1.0) to show the ramps slope being 2% away from enclosure as well as the enclosure slab sloping 1% to the gate.
c. If some details are desired to proposed differently from what’s provided in TSM 8-01, a TSMR with ES approval will be required.
17. Where a development is intending to provide centralized storage and collection to serve multiple buildings, tenants, or businesses, a general note must be included within the plan stating, “A single property owner, property management company, or homeowners association (HOA), will be responsible for the management and maintenance of the solid waste collection services and storage area(s) for all development/business occupants.” TSM 8-01.5.1.D
Grading Comments:
18. Provide Total cut/fill quantities on sheet 8 (C1.0).
19. Show the 2-foot minimum grading setback from the property lines on the grading plan TSM 2-01.9.0
20. Provide a descriptor box adjacent to each basin on the grading plan (Includes Stormwater Harvesting basins/landscaping). Include a leader arrow to the basin or provide a label for the basin and reference the label on the top of the descriptor box. Include the following applicable information in the descriptor box: a. Total volume, cubic feet or acre feet; b. If applicable, detention volume, cubic feet or acre feet; c. If applicable, retention volume, cubic feet; d. If applicable, first-flush retention volume, cubic feet; e. If applicable, Q100 in, cubic feet per second; f. If applicable, Q100 out, cubic feet per second; g. Basin top elevation, feet; h. 100-year water surface elevation, feet; and i. 100-year ponding depth, (measured from the lowest elevation of the basin), feet. DSSDR 11.1.3. This can be done through an additional detail sheet or included on current basin detail sheet if the grading plans appears too narrow for such detail.
21. Show that erosion protection is used for all inlet and outlet structures on the Grading sheet and details. The erosion protection shall extend below the finished grade of the basin floor and/or side slope to the appropriate design depth. DSSDR 4.8.1.4 Show this for all inlet & outlet structures.
22. Basins shall have a minimum of 1 sediment level measurement device, which can be incorporated into the weir or the side slope or constructed as a separate stand-alone device. The device(s) shall be located where sediment is likely to accumulate DSSDR 4.4.1.4
Drainage report comments:
23. When stormwater harvesting basins with terraced cells are proposed, internal check dams to pond water shall be provided. a. The minimum freeboard shall be measured from the top of the check dam to the lowest finished grade adjacent to each cell. b. Check dams shall be keyed in a minimum 12 inches into the side of the basin. DSSDR 5.3.1.10
24. An inspection and maintenance protocol including frequency of inspection, a checklist of items to be inspected and recommended maintenance when an inspection identifies a maintenance requirement shall be prepared by an Arizona registrant should be included at the end of the provided drainage report. DSSDR 4.1.1
25. Due to the shear amount of retention required/proposed for this development, it will be required that infiltration (Percolation) testing be done for all four proposed Ret/Det basin locations.
a. Justification – Site consists of Type C & D soils which are associated with slower infiltration rates when thoroughly wetted. This is also due to retention provided exceeding 10,000+ CF

It should be noted that additional Site Engineering comments may be forthcoming in future review cycles as provided comments and development changes may bring forth further callouts.
