Happy owners. Happy developers. Happy users. Increased ROI.
Throughout our careers, we’ve found these things to be the root of success when it comes to land development design. Although there are many different types of land development – single family, multi-family, retail, commercial and industrial to name a few – all projects have fundamental commonalities. Regardless of development type, we at SEH live by the following principles.

Below, 10 land development design rules to consider before building.
Even the best development plans need engineering adjustments. Without master engineering, concepts that appear ready for platting may prove to be unworkable in construction. Master engineering validates the feasibility of the plan and incorporates infrastructure (sewer, water, transportation, storm sewer, gas, electric, telephone and fiber), earthwork (grading), lot configurations (lot width), trails and amenities. All too often a master plan looks great on paper, but can have inherent technical flaws and doesn’t consider the engineering challenges. The goal of a good land development engineer is to work with the master plan, tweaking and revising with the planner/developer as necessary to better incorporate infrastructure and cost efficiencies. Making small adjustments to the plan can mean big positive changes to the return on investment (ROI) and to the owner.
When a bid for the grading and storm sewer work at a single-family home project in Omaha, Nebraska came out higher than anticipated, the developer faced a much reduced return on investment. With the help of SEH, the developer was able to to consider an alternative – "master engineering." Through master engineering SEH tweaked the site layout, grading, and storm sewer design, which resulted in significant savings for the developer. The grading changes reduced the project cost by $225,000. The storm sewer changes reduced the project cost by $275,000. Along with reduced costs, the project team was able to add more premium lots to the development which could be sold at more than $10,000 per lot.
Listen to what the land has to offer, carefully take in the surroundings and visualize what your additions will offer. Walk the entire property – this may seem old-school to some but will pay dividends later.
In every development, we walk the site with the owner. It is amazing how many times we pick up on small details that become amenity features or we identify elements that will prove challenging and costly and may need to be reimagined.
Eliminating and/or anticipating challenging conditions early in the process has a direct cost-benefit which, in our experience, can be significant and ultimately impacts a project’s ROI. Design a development that suits the land’s natural shape and form. Are there unique features? Can they be enhanced to create an amenity or corridor view that helps increase marketability and ultimately ROI?
For example, in the Bridgeport development in Nebraska, the development team created a network of connecting trails and a boardwalk across a wetland channel. The boardwalk allowed the team to circumvent costly earthwork while adding an element to the development. By listening to the land at the onset, the developer was able to better connect the different public areas of the development and create a nice walking feature for residents to enjoy.
Look at ways to be efficient in design. Often, designs seem efficient but are littered with wastes of space. Here are three common examples:
People. People. People. They can make or break a successful land development. Put the right people in the right role on the right projects and you’re virtually guaranteed to succeed. Be careful, even the best people are not enough without clearly defined roles and integrated communication. Also, pay attention to the market — even the best talent can’t change market conditions. Make sure the developer, contractor, and city officials are in sync, as they all have different priorities. Gaining an understanding of where the other parties are coming from enables a more seamless project. Developing a relationship, asking the right questions, being professional – it all helps in executing the project.
This is the low hanging fruit! The two largest areas to influence development costs are earthwork (grading) and stormwater management. For single family and multi-family developments, start with the homes first. From here, design back yards to the property boundaries and front yards to the street. This reduces the need to move dirt and efficiently manages stormwater. Earthwork (grading) is an iterative process. We typically have several iterations included in a design. This also balances and reduces grading, each time reducing costs by as much as 20 percent.
Beginning with street design is an easy mistake to make. Municipal engineers often design the street layout, then fit the houses around it. But people don’t live in streets, they live in homes on lots. “Happy end-users” hinges on designing the homes and the lots first, while saving the streets for last – this is how successful land development engineers work. This way, you’re keeping the focus on the people who will be most impacted by your design. Often times, we can increase the lots per acre while also increasing the green space, creating a more livable neighborhood. It may seem counterintuitive, but it’s true. Challenge yourself to reduce street length while increasing density and/or green space.
There's an old saying among engineers, “stuff doesn’t run uphill.” What appears to be an efficient design for the first phase of a multi-phase project may not suit future phases. Topographic maps are essential for learning the geologic and hydrologic characteristics of a property. Combine them with assessment photos and it can help you determine how the property has changed over time. Don’t be afraid to incorporate new technologies to make the best use of your space. Drones can help you see and understand every inch of your property. Three-dimensional mapping technology shows you the property from a completely different perspective – and helps you guarantee you’re putting your buildings in the right place. In addition, nothing beats drone photography for marketing the amenities a neighborhood has to offer.
Take a holistic approach to land development design. Integrate stormwater by turning stormwater conveyance into amenities while minimizing piping. Connect residents to features and destinations by planning pedestrian flow. Lay out your lots to maximize view corridors. Home placement is crucial – don’t block the views of another, or it will impede on the enjoyment of the area.
Everything should add up to a perfect whole. Be intentional about seeing the forest through the trees, which sometimes requires adjustments. Think about adding trail systems, parks or other shared elements. People like feeling part of a group. Reinforce that sense of community. Use visualizations to attract prospects. Show people what they’ll get. Experiencing the space before purchasing can help pull in buyers. At the same time, visualizations can help turn detractors into supporters.
Routines are great for efficiency, and often play an important role in getting a project done quickly. But we can’t forget to think outside the box. Every land development is unique, each with its own challenges. If we fail to incorporate these nuances into the design, we can miss opportunities to change the status quo, and increase ROI. Consider the following when selecting products and projects: community amenities such as pools, party rooms and playgrounds may be just the thing to lure in a prospective group of buyers.
Don’t forget about Fido. According to the American Veterinary Medical Association, nearly 40 percent of homeowners are dog owners. Create friendly places to walk and play. Consider community areas around dog amenities to help create that neighborhood feel. Aging populations may be looking for amenities like snow removal, lawn care and other services. How might these impact design? How does it affect the long-term sustainability and operation of the development?

Even with the best-laid plans, there will be challenges. If a challenge arises it’s an opportunity to reach out to professionals for help. Engineers are problem solvers by nature. Also, listen to what the market is saying. Is the current housing trend to have homes without stairs and at minimum three-stall garages? This affects the design — specifically lot width. Share market data with project teams. Projects can move forward easier when everyone is in sync.
The market, housing trends, interest rates and consumer preferences – among other things, are often out of our control in the world of land development. If we remember the fundamentals and stick to the rules, we can positively impact what we do control, give ourselves the best chance for success, increase ROI, and achieve happiness for everyone involved.
