Windler Homestead is an active lifestyle retirement community located in the City of Aurora, Colorado.  The site consists of approximately 400 acres, on which sits 1400 homes, a 20,000 SF clubhouse, recreation center, pool and spa, tennis and bocce ball courts, walking trails, and more.  Easements included 15 separate parcels. Parking included 140 spaces. Calibre planned and designed over 4 miles of major water and sanitary sewer lines, ranging in size from 8 – 36” and multiple borings of E-470 of over 500-feet.


Calibre’s design specifically preserved the unique mountainous views of the south-Denver area, ensuring the dignity of the project.  Calibre provided the contextual site plan, grading and erosion control, construction management, platting, parking lots, roadway, water, sewer, and storm utility improvements,  preliminary and final drainage plans, SWMP, water and sanitary sewer design, due dil+igence, design survey, traffic report, master drainage, easements, preliminary and final grading, and 80-acre ALTA plans.  Calibre was also responsible for design and improvements to several arterial roadways and major roadway intersections including Gun Club Road, 48th Avenue, 56th Avenue, and Harvest Road.


Calibre performed master planning analysis and modeling of sanitary drainage basins and coordinated with City and adjacent landowners on potential pumping options. Construction document preparation for the trunk and interceptor lines was fast-tracked to provide plans for the Client’s preferred construction timing. E-470 permitting and coordination was critical in securing the permits at the same time the City permits were received.


Calibre was brought in after initial submittals had been made by others and was able to correct and regenerate construction documents in two months and close the gap on the ultimate project infrastructure schedule by one month.


Calibre identified infrastructure redundancies and oversized facilities in previous designs and reduced the overall construction budget from $5M to $4.5M. This infrastructure savings also reduced the maintenance cost for the City.
