Tobias Terrace Apartments is a new 56-unit, four-story multifamily residential housing development in Van Nuys, Los Angeles, CA. From the project’s conception, Meta Housing Corporation’s intent was to design a project that utilized the maximum of Low Impact Development and sustainable design principles. The original target was for the project to achieve a LEED® (Leadership in Energy and Environmental Design) for Homes Gold certification.

An Integrated Development Plan was initially developed in order to target the highest possible levels of energy efficiency. Some of the sustainable features in the plan included a solar hot water system, efficient lighting/appliances and low-flow plumbing fixtures that would decrease water and thermal energy consumption.

While performing civil engineering services for the project, KPFF Consulting Engineers needed to continue to provide sustainable design solutions. KPFF chose to utilize the combination of a CDS® system and perforated HDPE (High Density Polyethylene) pipe for the project’s stormwater management system, products offered by Contech Engineered Solutions. The two firms had worked successfully on a variety of past projects, and KPFF knew Contech was experienced both with providing sustainable design solutions and in winning approvals from local agencies.

The CDS® system uses continuous deflective separation to effectively screen, separate and trap debris, sediment and oil from stormwater runoff. Using the system can contribute to helping a project achieve a variety of LEED credits, including those involved with stormwater quality control, water efficiency, water efficient landscaping and use of recycled content and regional materials.

The project has actually exceeded its original expectation of pursuing a LEED for Homes Gold certification and is now pursuing a Platinum certification, the most prestigious level of LEED certification that a project can achieve.
