The basin entry drains are at the corner of Rancho Aldea and Valle de Costa (south-eastern corner). They are part of a two-system drainage system emptying water into the seepage pits of the water detention basin. They do not empty into a city sewer system drainage system.
The photos exhibit the deterioration of the drainage system, the crack in one pit, and the separation from the curb/basin and the drains.
The curb separation and the crack in one of the pits are a concern and need addressing.
