Raptor Civil Engineering is proud to be part of the project team behind Ellery at Sloan’s, a new 27-townhome development bringing additional housing and thoughtful infill development to Denver’s Sloan’s Lake area.
Developed by Thrive Colorado, the project transforms a long-vacant property into a coordinated five-building residential community. Raptor Civil Engineering provided engineering expertise as part of a multidisciplinary team working to bring the development from planning toward construction.
27 New Townhomes Near Sloan’s Lake in Denver
Ellery at Sloan’s consists of 27 three-story townhomes distributed across five buildings. The homes incorporate garages and rooftop decks alongside site improvements designed to create a cohesive residential community.
The overall development includes:
27 new three-story townhomes
Five residential buildings
Private garages and rooftop decks
Organized internal circulation and site access
Alley improvements
Utility infrastructure upgrades
Landscaping and site lighting
Site planning coordinated with Denver zoning and development requirements
The redevelopment increases housing capacity on an underutilized Denver property while contributing to the continued pattern of medium-density infill development around Sloan’s Lake and West Denver.
Civil Engineering for Denver Infill Development
Urban infill projects present a unique set of civil engineering challenges. Unlike development on previously undeveloped land, project teams must coordinate new construction with existing streets, alleys, utilities, drainage systems, neighboring properties, and established municipal infrastructure.
For projects like Ellery at Sloan’s, effective civil engineering and site development design are essential to creating a site that works both on paper and during construction.
Raptor Civil Engineering works with developers, architects, contractors, and other project stakeholders to help address these considerations through services including land development engineering, site development design, grading and drainage, utility coordination, and construction surveying.
Our goal is to develop practical engineering solutions that account for municipal requirements while keeping constructability and the overall development objectives in focus.
Supporting Denver's Continued Infill Development
Projects such as Ellery at Sloan’s demonstrate how vacant and underutilized properties can become new housing within established Denver neighborhoods.
Adding density to existing urban areas requires careful coordination between architecture, civil engineering, construction, utilities, landscaping, access, and municipal requirements. Raptor Civil Engineering is proud to contribute its experience to projects helping shape the next generation of development throughout Denver, Colorado.
