Report
Summary
The Federal Emergency Management Agency’s (FEMA) Pre-Disaster Mitigation (PDM) and Flood Mitigation Assistance (FMA) Grant programs are administered by DEMA on an annual basis. The City and the FCDMC propose to construct:
(1) Mandan Street Flood Mitigation Project: a floodwall behind several residential structures adjacent to Phoenix Mountain Preserve. This project will help prevent flood hazards to several residential structures in the area. The FCDMC will be the lead agency for project construction, and the grant application will be submitted in collaboration with the FCDMC.
The proposed flood mitigation project will have minimal impacts within the Phoenix Mountain Preserves boundary adjacent to the affected residential properties. Because of the impacts, which is allowed in accordance with Phoenix Charter Chapter XXVI, City of Phoenix Mountain Preserves, Section 3(c)4, the proposed flood mitigation project received approval from the Parks and Recreation Board on April 28, 2016.
(2) Palm Lane and 30th Street Storm Drain: A storm drain will be constructed along Palm Lane from 28th Place to 32nd Street. The new storm drain will connect to an existing 57-inch storm drain in 32nd Street. This project will mitigate flooding along Palm Lane and along 30th Street. The City will be the lead agency for project construction, and the grant application will be submitted in collaboration with the FCDMC.
Both project grant applications are dependent on when the application process is opened, and how much federal funding is available for the projects.
Financial Impact
(1) Mandan Street Flood Mitigation Project: The total estimated project cost is $923,200. Of this amount, the FEMA PDM/FMA Grant program will reimburse the City up to 75 percent of the estimated costs or $692,400, if awarded. The required local match of up to 25 percent will be shared between the FCDMC and the City, who will each provide up to 12.5 percent or $115,400 each. The required City local match is available in the Street Transportation Department’s Capital Improvement Program budget.
(2) Palm Lane and 30th Street Storm Drain Project: The total estimated project cost is $2.1 million. Of this amount, the FEMA PDM/FMA Grant program will reimburse the City up to 75 percent of the estimated costs or $1,575,000, if awarded. The required local match of up to 25 percent will be shared between the FCDMC and the City, who will each provide up to 12.5 percent or $262,500 each. The required City local match is available in the Street Transportation Department’s Capital Improvement Program budget.
Concurrence/Previous Council Action
The Parks and Recreation Board approved the proposed project for City Council authorization on April 28, 2016. The City Council adopted the proposed project on May 4, 2016, Ordinance S-42514.
The City Council adopted the proposed project on April 20, 2016, Ordinance S-42476. The proposed project was scheduled to be completed under the FCDMC's Small Project Assistance Projects (SPAP) program with an estimated cost of $1,261,000. Since that time, the estimated project cost has escalated as the project has been further defined. It is now too large for the SPAP program. Therefore, staff is pursuing additional DEMA and FCDMC funding sources based on the revised estimated cost.
On May 9, 2017, the Transportation and Infrastructure Subcommittee recommended approval of this item by a vote of 4-0.
Location
The proposed floodwall will be constructed in the vicinity of Mandan Street and Sacaton Street. The Palm Lane Storm Drain Project is located west of 32nd Street and north of McDowell Road.
