Trinity Horizons – An Exciting Dream Moves to Reality

What is Trinity Horizons?

For many years, Trinity dreamed of building additional church space and affordable housing on what was once the north parking lot of the church on the southeast corner of Mapleton & Broadway in downtown Boulder. This project became Trinity Horizons. Our dream became a reality in 2019! The shared space supports many community needs:Trinity Horizons

  • Provides 16 permanently affordable, one bedroom, senior housing units. Named Trinity Commons, this serves a senior housing need in Boulder’s vibrant downtown core with the potential to build up to 8 more in the future.
  • Provides a shared parking structure that offers downtown parking to the public as well as church members. This was built in conjunction with CAGID, the City of Boulder’s Central Area General Improvement District that manages downtown Boulder parking.
  • Provides 5,000 square feet of new church space. The bulk of the space is the Fellowship Hall, a multi-purpose space that will be used for the various church and community ministries and programs we support.


How does the community benefit from Trinity Horizons?

Trinity has worked for over 40 years to make the dream of Trinity Horizons a reality and we’re Trinity Horizons Project is Building Communityexcited about this shared space. This project enables Trinity to further our work to serve as “a mission outpost in a troubled world” and benefit the community at the same time. In addition to providing additional gathering space for our church community, Trinity Horizons provides the following benefits to the broader community:

HouseIconTrinity Commons: Senior Affordable Housing – Affordable housing continues to be difficult to find within Boulder city limits, and was non-existent in downtown Boulder. Trinity Commons provides 16 much-needed one bedroom affordable housing units for seniors. This housing meets community goals of providing affordable housing within Boulder’s walkable, active downtown core. Seniors must be 62 or older and must not exceed 60% of the median household income in Boulder County. The housing is being managed by Mock Property Management. For housing inquiries call Margaret Flaherty with Mock Property Management at 3O3-497-0668.

CarIconBoulder Parking Garage – As the Boulder downtown density grows, parking becomes more challenging in the downtown core. The new parking structure allows us to maximize the space and utilization of parking in our downtown location. Public parking is owned and managed by the City of Boulder’s CAGID.  With access off the alley between Pine and Mapleton, CAGID leases 56 spaces out monthly during the business day and moves to hourly operation in evenings.  Trinity has exclusive use of the lot on Sundays and limited access during the week for church evening activities through a validation system. Additionally, there is a Trinity-owned garage with 26 parking spaces with access off Mapleton. Trinity leases out 16 of the spots to residents of Trinity Commons Housing or area businesses with the remaining 10 spots designated for church staff and volunteers.

ChurchIconTrinity Fellowship Hall: MultiPurpose Space – In addition to church activities, this new large multi-purpose space allows us to continue to serve and provide additional meeting room for various community groups. We host self-help groups such as Alcoholics Anonymous, mental health support groups, those who are homeless or hungry in our community, music groups, and other not-for-profit organizations. The expanded facilities provide additional capacity that is easily divisible. The facility includes a commercial kitchen, church offices, and additional restrooms.

We offer free parking to our congregants and visitors, however as the structure is managed by the city we have some rules to follow.

Monday – Saturday Parking: Click here for a detailed parking plan for all days of the week.


How much did Trinity Horizons cost, and who funded the project?

The project cost over $11 million to build, including the land for the project which has been donated outright by Trinity Lutheran Church along with the church’s capital campaign funds.

Interesting finds:

Since Trinity is receiving federal dollars from Disaster Relief funds, we had an archeologist on site during excavation. The archeologist found glass bottles (a few incredibly nice ones), ceramic vessel pieces (likely from a chamber pot or a spittoon), a full eyeglass kit, and a daguerreotype photo. Our archeologist is most excited about the Daguerreotype, as it is complete and in its frame.  He found most of these things in what he thinks was a well that likely went dry and then things were thrown into it. Read the Daily Camera’s article about our excavation findings.
