  • Atherton Town Center | Town of Atherton

    Atherton Town Center | Town of Atherton

    Recognizing the need for a functional and welcoming space for civic activities and community engagement, the Town of Atherton created plans for a new $60 million Civic Center Complex, complete with council chambers, a library, and facilities for town administration and police department.

    Though planning for the Town Center began in 2012, the project broke ground in 2019. It was crucial to the Town to have complete stakeholder buy-in and community involvement. Plans were drawn and changed several times to ensure that the project properly represented the vision of Town Leadership, reflected and preserved the rich cultural heritage of the Town, and respectful of concerns expressed by adjacent neighbors and Town stakeholders. Interwest Project Manager, Marty Hanneman, has effectively and successfully formed important partnerships and wonderful relationships with Town residents and vocal stakeholders as he responded to their questions and found solutions to their concerns throughout the planning, design, and construction of the project.

    Once the plan was agreed upon and construction started, the project faced an unexpected and unanticipated challenge: the COVID pandemic. Like so many construction projects this year, the Town Center was put on hold for several months as the Town adopted and implemented health and safety best practices. Eventually the project was allowed to proceed, as the Town Center will be an essential service building; even so, moving forward remained difficult as several of the required suppliers and tradesmen were not considered to be essential workers. Even though months of productivity were lost, it is a testament to the team’s determination and dedication that the project is still on schedule. Limited staff are expected to move in under a temporary certificate of occupancy in July 2021 with the rest following shortly thereafter in October.

    Interwest has served the Town of Atherton since 2011 providing Municipal Engineering, Building and Safety, GIS, and IT services, as well as technical assistance and support to the Town Manager, Town Council, appointed Committees, and the community on programs, policies, activities and projects.

The building contains a dispatching center, administrative offices, meeting rooms, driver rest areas, and our vehicle maintenance shop. The facility yard is equipped with a drive-thru bus wash and fueling depot that dispenses unleaded gas, diesel fuel and Compressed Natural Gas (CNG). Additionally, there are four 80-kWh electric bus charging stations used to charge electric buses.
  • Limonite Interchange | City of Eastvale

    Limonite Interchange | City of Eastvale

    In 2018 the County of Riverside approved a contract to improve the Limonite Interchange on Interstate 15 (I-15). The $39 million dollar improvement project consist of a new 8-lane overcrossing, 3 through lanes in each direction plus 2 turn lanes, widening of the off-ramps from 2 to 4 lanes, the addition of 2 new loop on-ramps, and the widening of Limonite Avenue to 4 lanes in each direction between Hamner Avenue and Wineville Avenue. With the continued development and growth in the city of Eastvale, and in the inevitable increase in traffic that will result of said growth, the I-15/Limonite Interchange improvements are designed to accommodate the existing and future traffic associated with the planned development.
  • Grand Avenue Bike Lanes, Phase I & Phase II | City of Wildomar

    Grand Avenue Bike Lanes, Phase I & Phase II | City of Wildomar

    Our team prepared and secured competitive grant applications for the City of Wildomar for Phase I and II of their Grand Avenue Bike Path projects. These projects provided approximately 5 miles of Class II and Class III bike lanes along a major corridor running the entire span of the City. Improvements allowed for connectivity and alternate modes of travel for residential communities, school children, commuters, and recreational activities that will also result in improved air quality and traffic congestion relief for the community. The project's cost of $2,999,131 was funded by $500,000 in MSRC money, $1,360,400 in CMAQ funding, $567,800 of SB821 money, $30,000 in AB2766 funds, and $570,931 in Local Funds.
