Mineral
Springs - The Complete Story
"The design for Mineral Springs is an effective example of how flexibility
in an otherwise conservative land-use tradition can provide for more efficient
development and preserve the public’s investment in a Wild and Scenic
River."
(Quote from Minnesota Land Trust
& University of Minnesota Study)
Mineral
Springs is a unique residential community consisting of 160 acres of river
bluff and prairie along the north shore of the Cannon River in Central
Minnesota. A "Wild and Scenic" designation by the Minnesota Department
of Natural Resources (DNR) pays homage to the natural beauty of this site
which includes nearly one and a half miles of shoreline and a small island.
This designation also means stringent regulations to protect Minnesota's
rivers. Regulation like "cluster development" has been adopted by the
DNR in Wild and Scenic districts as an attempt to protect large areas
of the natural landscape. Developers are allowed to group houses close
together (closer than county zoning ordinances generally allow in rural
areas) in exchange for a promise to provide large protected plots of undisturbed
land. Seen as cutting edge sustainable design limiting low density suburban
sprawl, the cluster approach in reality seemed to us little more than
a miniature version of traditional town growth. We kept asking ourselves,
"isn't there another way to protect the natural setting without clumping
everyone together? Is there really a dichotomy between pristine nature
and ugly human settlement?" These questions began to haunt us while working
extensively with the DNR and Goodhue County to explore the possibilities
for the project. Surprisingly, after voicing our concerns both agencies
encouraged us to challenge their ideas of "cluster" development and residential
growth. Ultimately we developed a community plan that broke some rules
even though it respected the philosophy behind the cluster development
concept.

In our solution human settlement is interwoven with, and co-exists with
nature. Small privately owned lots of approximately 2 acres are sprinkled
throughout a large permanently protected open space. Over 80% of the property
is held in trust allowing residents to live immersed in a game preserve.
Responding to the diverse natural topography, Mineral Springs is composed
of three distinct "topographic clusters", Prairie, Hill, and Forrest.
All provide distinctly different environments that building sites must
respect. The Prairie for example is a large flat river bench restored
from cornfield to indigenous prairie grass. To keep this prairie intact
we envisioned it as a lake, all building sites sit around its perimeter.
Roads are not allowed within the prairie either. Throughout the development
care was taken to impart a low-impact attitude towards the land. Home
sites were placed in existing clearings to avoid tree cutting and earth
moving. In addition, each site has a unique sense of place oriented towards
the river and natural context. Roads avoid separating homes from the river
or primary views. All sites have southern exposures. We took great pains
in situating the roads to reduce earth moving and tree removal. Initially
the county wanted a pre-defined layout until we convinced them that would
not allow us to be light on our feet. Only 18 feet wide, these roads were
narrowed below the county minimum of 24 feet (established for agricultural
purposes) to reduce hard surfaces, improve storm water runoff, and provide
a lower visual profile. Storm water is not concentrated into a water containment
system like most developments. In dispersing storm water the restored
prairie plays a significant role. The indigenous but specially formulated
prairie grass not only preserves top soil but expires significant amounts
of moisture into the air. Additional storm water percolates through granular
river bench soils.
