09/26/2007 MATT FLICK ENGINEERING REVIEW Approv-Cond T07BU01363, T07OT01454

The grading plan and drainage report have been reviewed and are conditionally approved. The following comments are offered:

1. The hydrology for the tributary channels appears to neglect the culverts beneath the Interstate Highway that allow flow from east of the Interstate to pass onto the Tucson Spectrum property and, thence, into the tributary channels.

2. The watershed map identifies a substantial area in the northern part of the Spectrum as being tributary to Airport Wash. Under existing conditions, much of the area does not contribute to Airport Wash flows.

To avoid further confusion as to what flows should be used for the channel design, it seems logical that those flows would be the calculated flows from the Tucson Spectrum project. If the consultant reviews the flows from the project, and is in agreement with the discharges, those flows could be used in the design of the tributary channels. A statement indicating agreement with the calculated flows would need to be inserted into the drainage report. It is not necessary to recreate the hydrologic data and watershed maps from the previously-approved reports. The flow rates can be given in a table. Hydraulic data related to the tributary channel and culvert design must be included.

The grading plan and floodplain permit will be approved following resolution of the tributary drainage design.

10/04/2007 ANDREW CONNOR NPPO REVIEW Approv-Cond Grading is approved subject to compliance with PIA plans and any provisions for native plant preservation. LUC 3.8

Grading is to be consistent with the plans for the linear park and revegetation associated with the modifications proposed for the Santa Cruz River.

The plans are subject to the following rezoning conditions: C9-05-23

The owner/developer shall design and construct the Santa Cruz River bank protection and lineal park amenities from Irvington Road to Drexel Road, as directed by the Tucson Department of Transportation and the Tucson Parks
and Recreation Department as stated in the pre-development agreement approved by Mayor and Council.

The owner/developer shall construct a segment of the Santa Cruz Riverpark on the east and west banks of the Santa Cruz River extending from Irvington Road to Drexel Road. The Riverpark segment shall be constructed to the City/County Riverpark standard, to include a twelve foot
wide paved path, an eight-foot wide meandering trail, landscaping with native trees and shrubs, and an irrigation system. Specifications for the paved path is two-inch thick asphalt with three-inch thick compacted ABC base. Specifications for the trail are two-inch thick decomposed
granite compacted to 95% over native sub-grade compacted to 95%. The specific design of the Riverpark shall include appropriate signage and lighting as determined in consultation with the City and County Parks
Departments.

The owner/developer shall construct a rest area with a ramada, picnic table seating, landscaping and access to the Riverpark near the existing parking area on the west bank of the Santa Cruz River on the south side of Irvington Road. Specific design of the improvements of this area shall be
subject to consultation between the owner/developer and the City and County Parks Departments.

Paths and trails shall be protected from wash flows, erosion, slope wash downs, drainage from adjacent streets and properties. Drainage shall be diverted away from paths and trails to designed culverts or pipe drainage
under paths. Flows from the street or other collection areas shall be designed away from and underneath paths and trails.

All Riverpark, rest area and trail improvements shall be constructed according to City and County standards.
