Progress on the Permanente Creek Flood Protection Project continues with notable construction of improved baseball fields at McKelvey Park. The new baseball field will double as a place to contain floodwaters when Pemanente Creek overflows. This construction is happening simultaneously with channel widening work along Permanente and Hale creeks which started this spring. Work on the streams is expected to be completed at the end of the year.

McKelvey Park is scheduled to be completed in spring 2019.  The community highlights for this portion of the project include new and improved baseball fields with terraced bleachers, a mini-park facility with playgrounds, concession and scorekeeper’s booth, storage, restrooms and a community room.

By serving as a flood basin, the new ball fields will reduce flood risks for neighboring homes and businesses by catching overflow from Permanente Creek and reducing the amount of water flowing downstream. The detention area will be approximately 4.5 acres and 18 feet deep. Once the storm passes through and creek flows recede, captured water from the flood basin will be redirected into the creek. Flood flows would inundate the site very rarely and the detention area would drain out in one to four days.

The challenges with designing flood protection projects in urban areas are existing land limitations to widen, deepen or install high floodwalls at existing channels. A flood basin is another way to protect neighborhoods and businesses from flooding. The Permanente Creek Flood Protection Project will provide flood protection for approximately 2,200 properties in Mountain View and Los Altos.

Check out a brief construction update from project manager Lotina Nishijima.



  1. Is there a way to use the water running through the creeks for drinking, irrigation or other purposes? Or does the Bay need it the most? I’m concerned we’re possibly wasting a valuable resource.


    1. arbrody,
      Thanks for your question. Valley Water has a three-fold mission: to provide safe, clean water; to protect the environment; and to provide flood protection. The water flowing through creeks is an essential component of this mission. We use the water in many creeks as one way to replenish our groundwater basins. The water in creeks throughout the county also supports the natural environment, including fish and wildlife and their habitat. We understand the desire to conserve this precious resource, and encourage everyone to do their part. For more information on our water supply, visit and click on “Your Water.”



    1. Just drove by McKelvey baseball park and I am guessing that it will not be open till next baseball season. Are they going to have a dedication of the new park? What about the plakes that where dedicated for Freddy Glenn the original care taker back when the park first opened?


      1. Thank you for the questions.
        We are planning a dedication event upon completion of the project at McKelvey Park. We anticipate construction to be concluded by the end of September; however, there may be follow-up work that could take one to two months.
        We anticipate McKelvey Park will be ready for the 2020 baseball season.
        Our team at Valley Water is not aware of previous dedication plaques. We are attempting to find an answer for you regarding the plaques.
