10/01/2010 ELIZABETH EBERBACH ENGINEERING REVIEW Approv-Cond DATE: October 1, 2010
TO: Chelsea Marshall L.A., Wheat Scharf Assoc.
SUBJECT: Sentinel Peak Regional Natural Resource Park improvements
LOCATION: 1501 W SENTINEL PEAK RD, T14S R13E Secs14 & 15, Ward 1
REVIEWER: Elizabeth Leibold, PE
ACTIVITIES: T10CM02603 (site plan), T10BU01448 (grading plan)
FLOODPLAIN: Balanced Basin Management Plan, FIRM 2855K

SUMMARY: The subject property and proposed phased improvements include ramada structures, removal of some existing park features, pedestrian drop-off area, shaded rest areas, check dams and micro basins, and other park features to accommodate for the proposed Sentinel Peak Regional Natural Resource Park. Engineering Division of the City of Tucson Development Services Department has received and reviewed the submittal package and recommends conditional approval.

SITE/GRADING CONDITIONAL APPROVAL:
1) DS Sec.11-01: Address the following comments on next submittal:
a) Designate construction/stockpile/staging areas on grading sheet plan views. Or, at minimum, add a note stating that staging areas will be designated prior to commencement of construction and shall not exceed X square feet. (X is the amount of area that, when added to the disturbance area of phase 1 improvements, the total does not exceed one acre, otherwise a SWPPP would be required).
b) Provide total disturbance area in square feet on cover sheet or grading plan sheet for each phase (at minimum provide phase 1 data). Assure the disturbance areas used for construction/stockpile/staging are included in total disturbance area.
c) Any proposed slopes that exceed 2:1(H:V) grades can not be accepted without a geotechnical report. Revise details or provide a copy of a geotechnical statement with project recommendations including slope stabilization recommendations.
d) On detail 1 on sheet L1.5, address the following:
i) Label existing grade line on uphill side of detail, unless this line is something else - clarify.
ii) Dimension minimum depth of interceptor side swale.
e) Correct check dam detail on sheet L1.5. Contour lines need to be perpendicularly drawn; contour lines need to be parallel to check dam length. A note may need to be added clarifying that the check dams are to be placed within existing small rivulets where stormwater collection for natural looking water harvesting can be accomplished.
f) Resin stabilized DG path detail and signage appears acceptable for Mission View Trail. Add note to grading plan sheet on the sheet L1.2 that as-builts for this section of the improvements will be submitted after this trail is completed to assure no more than 5% slopes are constructed.
2) Update grading permit application activity number T10BU01448 on the sheet L1.2.

Submit 2 copies of the plans, one copy of geotechnical statement if applicable, and response letter. Once all items above have been addressed Engineering can stamp the plans for approval. I can be reached at 837-4934 if you have questions or if you would like to set up a meeting to go over comments or resubmittal.
