ACTIVITY: DP17-0095
SUMMARY: Engineering Division of Planning and Development Services Department has received and reviewed the proposed Development Plan Package. The following items need to be addressed:
1) Per AM 2-06.4.3 please add the case number (DP17-0095).
2) Grading note 7 on sheet 1 calls out the need for grading compliance with Development Standard 11-01.10. The current grading standard that governs grading is TSM Section 2. Please update as appropriate.
3) Keynotes 11 and 12 on sheet 2 call out existing retaining walls that appear to be retaining fill from the Cushing Street Roadway. The proposed grades show a grading slope away from the low side of these walls. Please verify that the structural stability of the walls and/or roadway is not adversely impacted by proposed grade changes proposed on the low side of these existing retaining walls.
4) There is a 5:1 slope callout adjacent to the section callout E/3 that shows a 4:1 slope. Please be consistent.
5) There is line work for existing riprap being shown at the southwest corner of an existing shared use path access point that is being impacted by proposed changes in grade. Please evaluate the need to reestablish this rip rap at a new location and/or provide notes regarding the disposition of such.
6) Per UDC 7.14.4, Section 10.3, Item 9 public storm drains shall be RCP. Please clarify the temporary nature of the proposed CMP, including when it will be removed and/or replaced with RCP on this publicly owned site. Section 3.1 of the drainage report states, "A temporary 18" CMP will be installed to outlet flow into the Santa Cruz River to help facilitate a smooth construction Schedule." There is a callout at the outlet of this CMP on sheet 2 that states, "Tie outlet into bank above asphalt path- Remove and replace bank protection as needed." Please clarify that bank protection to be restored to its original or better condition as required when CMP is removed and prior to Certificate of Occupancy is issued.
7) Per AM 2-06.4.8I please show 100 year water surface elevations at intervals not exceeding 200 feet. Please include the line work used to designate the water surface elevation in the legend.
8) Per the last paragraph of Section 3.3 of the drainage report, the existing bank protection has resulted in the erosion hazard setback not affecting the future building. Please verify this is correct or update this section accordingly. See the last paragraph of section 8.5.1 of the City of Tucson Drainage Standards Manual which requires the lining of protected channels to extend to the elevation required to include the freeboard requirement. Spot grades for existing or proposed bank protection should be included when the Development Package is submitted for review with the building shown.
9) Cross Section C/3 is being called out on sheet 2 where the new 2:1 side slope is shown within the 100-year City Floodplain per LOMR. Per the last paragraph of section 9.3.3.1 of the Drainage Standards Manual channel side slopes steeper than 3:1 may not use dumped rip rap. It must be wire tied such that the rip rap will not slip through the wire tied openings. Rock material provided by Caterpillar is acceptable for this bank protections. Please note plans to install bank protection per drainage standards manual prior to issue of certificate of occupancy. Design engineer to verify compliance based on appropriate rock sizing.
10) Add floodplain use permit number to plans.
