Located in West Lake Hills, Sundown Office Park is a two-story office building with a parking garage on 1.55 acres on the south side of Bee Caves Road at Sundown Parkway, approximately a mile East of Loop 360. The building contains 12,500 SF of office space. Doucet was the civil engineer for the project and was involved with zoning, platting and full civil design. The design included grading, paving, drainage, water quality and detention pond, water and sewer. Doucet was involved from conceptual planning through design and construction administration.

Doucet provided planning and civil engineering services for the Washington Mutual Bank Brach/Financial Center at 300 East Whitestone Boulevard in Cedar Park, Texas. The 4,000 SF free-standing branch bank is part of a larger retail development with other pad sites. Doucet helped coordinate this project with the adjacent development. Doucet incorporated the site plan with the existing site and survey information and processed construction documents, including grading, drainage and utility plans, for permitting, bidding, and construction. Doucet also designed an erosion/sedimentation control plan and an Edward's Aquifer contributing zone plan to meet the City of Cedar Park and the Texas Commission for Environmental Control requirements.

Whitestone Market is a three-phase retail development on property adjacent to FM 1431 between Parmer Lane and Vista Ridge Boulevard. It is a part of the Silverado Springs Master Plan in Cedar Park, Texas. Phase I consisted of the planning, engineering design, and permitting of 23 acres along the south side of FM 1431 between Parmer Lane and Market Street. A 78,000 SF H-E-B grocery store, approximately 30,000 SF of in-line retail, an H-E-B Fuel Station and one bank pad site currently occupy the site. The use of local limestone and sensitivity to the natural environment make this site special. Doucet’s knowledge of local materials and methods led to the use of limestone retaining and pond walls, a cost effective measure that added to the local character of the site. Doucet achieved fifty percent tree preservation through careful coordination with the city urban forester and performed an Endangered Species Habitat Investigation for Birds and Karst (cave) Invertebrates. In addition to Phase I, a 1500-foot-long commercial collector roadway, Market Street, was designed and permitted. Coordination was required with the Phase II design engineer and with the Silverado Springs developer’s engineer on the off-site street and utility work within the Silverado Springs development. Phase II consisted off the area along FM 1431 between Market Street and Phase III; work included planning, conceptual site planning, subdivision processing and engineering review of infrastructure plans on developer’s behalf. Phase III consisted of the design, permitting, and construction administration for a joint-use driveway to serve lots 1, 2, 3, and 4 as well as utility extensions to provide service to each lot. Doucet performed a Floodplain Determination Study and inundation easement delineation for easement on adjacent property. TCEQ Edward’s Aquifer Contributing Zone Permitting was also required.

Windsor Retail Park is an approximately 125-acre mixed-use redevelopment project to include retail, residential, commercial, office and hospitality elements. Doucet provided conceptual design and preliminary platting for this property which part of the property eventually became Rackspace headquarters.
