Description
Request to authorize the City Manager, or the City Manager's designee, to enter into a license agreement with Envision Dobbins, LLC for the construction, operation, and maintenance of a private stormwater pipe to be placed in the City’s right-of-way.
Report
Summary
Private development is responsible for providing on-site retention to meet the 100-year 2-hour storm event, per City Code Chapter 32C and the City of Phoenix Storm Water Policies and Standards Manual. During the developer's on-site construction, it was discovered that the water table is higher in this area of the City. As a result, the designed private underground retention system could not function, and an alternate design was necessary. The limited size of the development parcel to provide surface retention basins, and the inability to enter into a private agreement with adjacent parcels to establish a shared retention system, forced the developer to seek an off-site alternative method to capture and discharge stormwater. The developer obtained approval from the Arizona Department of Transportation (ADOT) to privately discharge stormwater into an ADOT-controlled stormwater basin. The developer requests to install 990 linear feet of private pipe in the right-of-way to convey onsite stormwater from the subject property to the South Mountain Freeway ADOT basin.
In conformance with City Code Section 31-40, the agreement will include a clause to indemnify and hold harmless the City of Phoenix against all liability, loss, and damage that results from the installation, maintenance, and repair of any private facilities related to this agreement.
Financial Impact
There is no financial impact to the City. Licensee will pay an annual fee based on the linear footage.
Location
Generally, within the south half of Dobbins Road, located approximately 700 feet east of 65th Avenue to the limits of the shared jurisdiction line between the City of Phoenix and the ADOT (South Mountain Freeway).
