Grinnell College Improvements | Grinnell, Iowa - Clapsaddle-Garber Associates

CGA recently had the honor to assist Grinnell College with several improvement projects.

We partnered with EYP architects to complete the design and construction of the new $90 Million HSSC complex. The project included a 3-story addition to joining the historic Alumni Recitation and Carnegie Halls on the west side of campus. CGA assisted in the design of a green roof and stormwater reclamation tank for use in flushing toilets and reducing stormwater runoff.

CGA teamed with ASG Architects on the new Admissions and Student Financial Services Building including a new pervious paver parking lot for stormwater management. CGA assisted the college with the relocation of existing historic student housing in order to accommodate the new construction.

In addition, the ASG/CGA team completed the design and construction of the Phase I Campus Landscape plan. Phase I design began in 2016, with construction beginning in 2017 and scheduled to continue through 2019 in conjunction with a new Admissions and Visitors Center and a 1-acre building addition connecting two historic buildings on campus.

Plans include a new pervious paver parking lot, sidewalks, city street improvements, pedestrian crossings, multiple bioretention cells, storm sewer including pedestrian trench drains, snowmelt systems, plazas, seating, outdoor classrooms, covered bike storage, pedestrian and vehicular lighting, pedestrian ramps, improved building staircases and ramping, landscape plantings, and underground utility services and relocations. CGA has completed the final layout and grading of all improvements completed on site to date.
