This project involves the evaluation and design of a new drainage system and pavement rehabilitation within Yachthaven Estates and the
northern portion of the Yellow Banks Grove neighborhood, which is located directly to the south of Yachthaven Estates. Many drainagerelated problems are experienced by residents during and after rainfall events in these neighborhoods. These neighborhoods are located in
the southwestern portion of the City, just east of the intercoastal waterway, and include the area bounded by 145th St N to the west, 143rd St
N to the east, Starboard Lane to the north, and 122nd Ave N to the south.
The existing drainage system of Yachthaven Estates is made up of three-sided open concrete ditches, which are both dangerous and
insufficient to handle the stormwater runoff within the neighborhood. The existing open concrete ditches are located along the edge of
the pavement and create a drop-off condition for vehicles and bicyclists. In addition, the concrete ditches are undersized and provide no
environmental benefits. Very narrow rights-of-way within this neighborhood will pose a potential design constraint. Additionally, insufficient
infrastructure within the northern portion of the Yellow Banks Grove neighborhood contributes to flooding. Engineering staff recommends a
coordinated approach with evaluating these two adjacent areas together, as a redesign of the drainage system spanning these two areas is
anticipated. Detailed surveying and geotechnical consultant services will be required.
The evaluation and design services would consider sustainability and resiliency with regard to the proposed drainage system. This project's
cost estimate does include construction administration costs but does not include the construction costs for these improvements. Based
on the design recommendations, the construction of various improvements would need to be planned and prioritized in the future with
additional phases. Final Construction costs would be inclusive of pavement rehabilitation. This project's cost estimate does include property
acquisition costs, if necessary, to be determined during evaluation phase of project. The project is include in the city's 2024-2028 Capital Improvement Program (CIP)
