A New Community in Murrieta

Alderwood is a 239-acre master-planned community under development in the City of Murrieta in southwestern Riverside County; the property has also been known as Golden City. The site is bounded by Antelope Road and Interstate 215 to the west, Baxter Road to the south and an open space reserve to the east. The community is planned to feature 495 homes, and it will also include 6 acres of future medical office/commercial space. Providing safety services to area residents is Murrieta Fire Station No. 4 that opened in 2005 on a one-acre site within the community. Occupying a 36-acre site in the master plan is Loma Linda University Medical Center – Murrieta, a 106-bed acute care, adult hospital that opened in 2011. The Alderwood community is being developed by SunCal, one of the largest real estate development companies in the U.S. that specializes in large-scale, mixed-use master-planned communities.

An approximately seven-acre parcel at the corner of Whitewood Road and Baxter Road is the site for Alderwood Park, a new public city park that is open to all Murrieta residents. Phase 1, which includes the western half of the park, completed construction in fall 2017 and is open for use. Phase 1 features two dog parks -- one for small dogs and another for large pets; a small tot lot; a gazebo picnic shelter with tables; and parking. Phase 2, which consists of the eastern half of the park, is anticipated to complete construction by the end of 2019. It will then be turned over to the city and they will determine when it is officially ready for public use. Phase 2 will offer a large kids' playground; open turf areas for play or relaxing; a patio and picnic tables; two half-court basketball courts; two pickleball courts; parking; and a 3,000 square-foot community center. The community center will have a common room, kitchen and bathrooms.

Construction Update

Rock Crushing and Hauling Nearly Finished

October 2, 2019


Rock Crushing Nearly Finished

Since the production blasts to break up the buried rock at Alderwood reached the lowest level required for the project during the last such blast on October 16, 2017, the many tons of rock rubble that resulted have continued since then to be removed, crushed into smaller pieces and hauled offsite. The rock crushing and hauling at Alderwood is nearly finished, and we expect to soon wrap up this stage of our work activity. Following this will be the grading of the remaining development areas and infrastructure installation; then home builders will construct the final neighborhoods in Alderwood.

Saturday Work Activity on Property

To help pick up the pace of rock-clearing, in March 2017 we added Saturday work activity to the schedule. This is in compliance with City permit regulations and activity hours will conform to the existing restrictions.

Rock-crushing Machine

Our crews constructed a 15-foot-high dirt berm around the rock-crushing machine.  The berm’s purpose is to deflect the noise of the rock crusher away from nearby homes.

Rock Hauling

Permits were obtained in summer 2016 from both the City of Murrieta and the City of Menifee to transport rock material off-site from the Alderwood property.

Rock-Breaking Process Overview

Construction involving the moving of boulders, demolition, rock-crushing and grading started the week of May 16, 2016. The involved areas are south of the existing neighborhoods south of Keller Road and will gradually see 500,000 cubic yards of material moved.

A rock-crushing machine is set up several hundred feet southeast of the existing neighborhoods south of Keller. In order to minimize the sound from this operation, we are taking an additional step beyond the City requirements and have built a 15-foot-high sound-attenuating berm to block some of the noise. We are crushing rock onsite to reduce the number of truck trips, and we are also recycling the rock for other uses on and off the property. Large trucks are using the access road that intersects with Keller Road, to the east of the property, and truck operations coincide with the land-shaping work.

We are working closely with the City of Murrieta to ensure that our work conforms to all applicable regulations and restrictions, but there is some unavoidable noise associated with the removal and crushing of the rock.
