San Timoteo Foothill Neighborhood Flood Protection – Moreno Master Plan Storm Drain Lines K-1 and K-4

The San Timoteo Foothill Neighborhood, which is the area generally bounded by Locust Avenue on the north, Juniper Avenue on the south, Pettit Street on the west and Weber Avenue on the east, has experienced frequent flooding during storm events. Repeat flooding has damaged local streets and private properties, disrupted local traffic and school bus routes, and disrupted the delivery of public and utility services to the area. Flooding occurs due to the lack of an adequate surface runoff conveyance system in the area. A storm drain system is proposed within local roads starting from Locust Avenue, along Carrie Lane to Kalmia Avenue, along Kalmia Avenue to Pettit Street, then along Pettit Street heading south to connect to the existing storm drain in Pettit Street just north of Juniper Avenue. This proposed storm drain system is identified as storm drain Lines K-1 and K-4 in the Riverside County Flood Control and Water Conservation District's Moreno Master Drainage Plan. Applicable street improvements will also be necessary to convey the surface runoff into the proposed storm drain system. These improvements will provide a flood protection level up to a 100-year storm event for the San Timoteo Foothill Neighborhood.

The project received federal funding from FEMA with Master Drainage Plan fees to be used as local match. It is anticipated to have the environmental clearance completed by the end of December 2017 and design completed by April 2018.
