Conservation Development

We start with what’s most important – the natural land features.

More Than Open Space

Watching the deer along the tree line at dusk. Strolling through the walking trails past coneflowers and prairie grasses. Sitting on the patio with your coffee while the morning light filters through the oaks. That’s what conservation development actually feels like to live in and it doesn’t happen by accident.

Conservation-style development starts with the land itself. Before a road is drawn or a lot is placed, we walk the property and inventory everything worth keeping: the topography, the tree lines, the wetlands, the natural drainage, the places where wildlife moves. Then we plan the neighborhood around those elements – not the other way around.

Most developers treat open space as whatever’s left over after the lots are placed. We treat it as the starting point.

What Is a Conservation Subdivision?

A conservation subdivision is a neighborhood designed around the land, not around lot counts. Natural features — wetlands, prairies, tree lines, topography — are preserved first; homesites are placed around them. Residents own a smaller private lot but gain shared access to trails, woodlands, and protected open space.

What Makes Our Approach Different

Streets and Lots Last

Where conventional development begins by placing streets and maximizing lot count, we begin by identifying what should be preserved. Homesites are positioned around the natural features of the land, which means fewer lots per parcel and more value in each one.

Water as a Biosystem

Our stormwater management facilities aren’t geometric retention ponds with mowed edges. They’re designed as complete biosystems, managed for ongoing wildlife habitat and natural water filtration, not just drainage compliance.

Managed Vegetation

We don’t just leave natural areas alone and call it conservation. We actively manage vegetation: protecting existing trees, removing invasive species, and fostering the growth of native prairies, wildflowers, and grasses that add beauty and ecological value over time.

Minimal Maintenance

Less manicuring means less chemical application, less cost to the HOA, and more genuinely natural spaces. It’s better for the environment and better for your wallet.

Nature at the Center

Natural features that would be destroyed in a conventional development – a historic farm structure, a wetland edge, a stand of mature oaks – are preserved and integrated into our land plans. Conservation development costs more to do well. We do it anyway.

Community Gathering Areas

Trails, rec centers, playgrounds, and gathering spaces are planned as destinations – accessible, attractive, and maintained. They’re where you’ll meet your neighbors and where your kids will grow up.

What This Means for You

When you buy a lot in a Siepmann community, the conservation space is included in your purchase. You own a half-acre homesite, but you own and have access to dozens of acres of trails, preserved woodland, open prairie, and shared gathering areas. You don’t maintain all of it, you just get to enjoy it.

Less to maintain. More to enjoy. That’s not a tagline. It’s how we’ve been building since 1943.

Our Land Planning Process

Discover the Land

We walk every property and document its natural features: soils, topography, vegetation, hydrology, historic elements.

Plan Open Spaces First

Natural resources are integrated into protected open space before a single lot is drawn.

Plan Amenities

Community amenities are planned around the natural and recreational opportunities the land offers.

Civil Engineering

Roads, utilities, grading, and stormwater systems are designed to work with the land plan, not override it.

Finalize Design

Developer, land planner, and civil engineer align on final homesite placement and landscape design.

Approvals

We navigate the municipal and regulatory entitlement process.

Our Conservation Values

Our goal is to foster relationships with local landowners so that we may develop neighborhoods to be proud of. It’s about respecting a property that has passed down through generations and the hard work that has come with it. When that chapter ends, it’s about embracing the old farm house, silo, or barn in our conservation style of land development. Conserving history, conserving natural areas, and conserving the family legacy are paramount to our land plans.

Ron Siepmann was a founding member of the Waukesha County Land Conservancy, an organization dedicated to protecting environmentally significant land in Waukesha County.

That legacy shapes how we approach every parcel we develop. We’ve voluntarily established conservation easements on lands with significant agricultural, historic, scenic, and wildlife value. It’s not a marketing position, it’s just how we were raised.
