City public works personnel have begun construction on the first of three projects that will take place along the 600 block of East Grandview Avenue in Sierra Madre over the next few months.
Project No. 1
The first project consists of constructing a new, permanent entry to the spreading basin facility. The new gate will replace the existing entry that’s adjacent to Sycamore Place. The project includes removal of a portion of the old rubble perimeter wall around the facility and the construction of new entry pilasters using the wall materials, according to the city. The first project is designed to facilitate the next two projects.
Projects No. 2 and Traffic Detours
The second project will begin on Feb. 4, when staff from the Metropolitan Water District (MWD) will arrive at the spreading basins and begin to make preparations for the construction of a point of connection to the 9.5-foot MWD Upper Feeder pipeline that traverses Sierra Madre along Grandview. Actual construction in the street will begin Feb. 14. The project will require the complete closure of Grandview between Feb. 21 and Feb. 28, along with around-the-clock construction activity during that period. The project will continue with intermittent traffic interruptions through April 21, according to the city. (Inclement weather may lengthen the project duration, beyond the current schedule.)
While traffic will be detoured around the work area along Foothill Avenue, residents are urged to use Sierra Madre Boulevard instead of the Foothill detour, out of courtesy to the residents of that neighborhood. Please assist MWD and the city in minimizing the impact on the project’s neighbors.
Project No. 3
The third project will be the construction of a 12-inch pipeline from the new MWD point of connection along the east side of the city’s spreading basin property to connect directly with the city’s water system at the maintenance yard. This project is not expected to have traffic impacts.
The MWD connection for Sierra Madre is being constructed in order to provide an emergency water supply for the city. The project is timely in light of one of the city’s four wells being damaged and out of service indefinitely, and in light of the decline in water levels in the City’s aquifer.
Both water projects are wholly funded by the San Gabriel Valley Municipal Water District.
