a) Admin Man Sec.2-06.4.9.N: In report, explain how the revised, proposed disposal system prevents contamination due to flooding. Also, discuss in report how the potential pollution of the groundwater supply is minimized with this design.
b) Tech Man Sec.4-04.2.3.1.2.F: State in report that any documentation and all necessary permits are to be obtained from state and federal agencies.
c) Admin Man Sec.2-06.4.9.N.2: State how there will be appropriate containment and/or diversionary structures to prevent discharged petroleum products from reaching drainageways.
d) As a permanent stormwater issue for this project, the plans and report shall clearly demonstrate how contaminants from site areas are kept out of the drainageways and other downstream drainage infrastructure.
e) Admin Man Sec.2-06.4.9.N.2: Show how there will be separated watersheds; show how parking area will be regraded to direct onsite parking area runoff away from fueling center and diesel fueling area, toward acceptable runoff areas / existing channels. The layout for the site may need to be revised to accommodate area before discharging treated runoff to existing channel or stormdrain system.
f) Tech Man Sec.4-04.2.3.1.2.E: Regarding long-term maintenance responsibility, specify in the drainage report the name, address, and telephone number of the person(s), firm(s), agency or agencies responsible for the ownership, operation, scheduled and unscheduled maintenance, and liability of drainage improvements within the parcel boundary (i.e., oil separator retention structure or system, drainageways, catch basins, or other drainage facilities/improvements).

City Engineer is to be notified if watershed conditions have changed to the extent that drainage systems no longer satisfy the requirements of the Floodplain Regulations. Specific guidelines should be included to discuss how maintenance shall be performed for both drainage structures (engineered basin that may be used in conjunction with a stormceptor or other oil separator device).
h) Tucson Code Sec.26-11.2.f(4), Tech Man Sec.2-01.4.C, Admin Man Sec.2-06.4.9.M: On grading sheet, revise and more clearly delineate subwatershed where stormwater runoff is to be conveyed to a oil separator type of infrastructure or stormceptor structure. Add additional spot elevations, and add grade breaks and subwatershed delineation to the grading and drainage sheet. Revise proposed pavement elevations at different points within the parking and fueling area to provide reference to revised grading and site drainage per the above comments.
i) Admin Man Sec.2-06.4.9.N.7: Label subwatershed flowrates on drainage report exhibit for fueling areas.
j) Admin Man Sec.2-06.4.9.M.1, Tech Man Sec.4-04.2.3.1.5.G: Label Grading/ disturbance limits on planview sheet. Keep in mind, any offsite construction may require offsite temporary grading construction or other easement.
k) Admin Man Sec.2-06.4.8.I.3: A symbol identical to that used to represent the water surface contour intervals on the development package planview sheets should be included in legend.
l) Tech Man Sec.2-01.4.C: Provide additional spot elevations at western entrance, to clarify/assure that stormwater runoff is contained within offsite ROW and does not enter site.
10) Admin Man Sec.2-06.4.7.B.2.b: Please provide a floodplain use permit application in next submittal for processing with this project.

STORMWATER POLLUTION PREVENTION PLAN COMMENTS:
13) Tucson Code Chap.26 Art.2: Stormwater Pollution Prevention Plan (SWPPP) does not meet minimum requirements of AzPDES Construction General Permit (CGP). Revise SWPPP according to the following comments:
a) Show, label, and provide leader line for the receiving waters either on location map on a planview on first sheet of SWPP, on vicinity map on exhibit, or on other planview.
b) Revise SWPP control planview to match any revised layout for stormwater runoff for oil separator.
SOILS/GEOTECHNICAL REPORT COMMENTS:
14) Tucson Code Sec.26.11.2(a)(2): Regarding section 4.1 of Geotechnical Engineering Evaluation report, due to clayey sands at site, consider adding notes that may be particular to this site, such as the requirement for over-excavation of existing fill at the site (up to 4-ft) to be replaced with engineered fill under structural areas.
Submit a copy of geotech/soils report in next submittal.
