RECOMMENDATION:
Staff recommends that the City Council adopt Resolution No. 26-0016 awarding an agreement to CWE in an amount not to exceed $99,996 for the American Martyrs Stormwater Sump Hydrology and Capacity Study.
Body
FISCAL IMPLICATIONS:
Sufficient funds of $100,000 are currently budgeted for this project. Approximately $99,996 will be utilized from the Storm Drain Fund for the American Martyrs Stormwater Sump Hydrology and Capacity Study.
BACKGROUND:
The City's stormwater sump is located at the 700 Block of 15th Street between the American Martyrs School and next to the school gymnasium. It is found in a specific low-lying area, where stormwater runoff from around 50 acres of developed land is directed into the sump and seeps into the soil below, replenishing groundwater. Occasionally, during times of significant stormwater runoff, the sump has exceeded its capacity, spilling over into the neighboring school playground and building zones, raising concerns about possible damage.
In 1999, a hydrology study was conducted to calculate peak runoff flow and volume during three storm periods, aiming to determine flood extents. The hydrologic method identified the 50-year, 4-day storm as the primary consideration for design improvements, reducing flood damage risk. A report was then prepared presenting four remediation options. The study evaluated gravity systems, a pump station, and direct dischar...
