Landscape architecture is the planning, designing, and managing of outdoor spaces to enhance both the natural and built environment.

Our landscape architects work with you to understand your wants and needs while considering existing site conditions such as topography, climate, vegetation, and accessibility in the overall design process. This process is applied to jobs of all sizes and scope, from residential and commercial development to streetscapes, parks, and campuses.

We specialize in:

  • Land Development Plans - Commercial and Residential

  • Park and Playground Design


  • Commercial Landscape Plans


  • Stormwater Management


At McMillen Engineering, our team of landscape architects and civil engineers work together to create well-designed and sustainable landscapes. Our landscape architects integrate aesthetics to site design while our engineers provide technical support with structural design and infrastructure design. This partnership ensures a final design that is technically feasible, accessible, safe, beautiful, and ready for construction. 


Whether you have a residential garden, a public park, or a commercial outdoor space, we have the expertise to create an inviting area that meets your specific needs and preferences. Our innovative approach and attention to detail will bring your vision to life and create outdoor spaces that look beautiful and function purposefully. 


We are committed to addressing all legal and regulatory aspects of our clients’ projects. Our extensive knowledge of zoning requirements, environmental regulations, local regulations, and building codes will guarantee the proper design and implementation of your project. We can navigate through potential challenges that may arise to provide a smooth and successful project execution.

Civil Engineering Design


When preparing land development plans our landscape architecture team considers factors such as site topography,  climate, pedestrian and vehicular accessibility, drainage, and vegetation to ensure the successful integration of landscapes with the built environment.

By integrating thoughtful design, sustainable practices, and collaboration, our landscape architects establish land development plans that create appealing and functional outdoor spaces while enhancing the overall environment and user experience.


Our landscape architects’ approach to designing parks and playgrounds focuses on the needs and preferences of different user groups to optimize functionality and fun. Our attention to detail when designing for various ages and levels of abilities ensures that we mitigate potential hazards and minimize safety risks.  We consider the needs and developmental stages of the users and incorporate play equipment and activities that support physical, cognitive, and social development. By strategically organizing the elements of recreational spaces, we can create a cohesive and user-friendly environment for everyone.

One of the distinguishing features of landscape architecture is its emphasis on the integration of nature into the built environment. Our landscape architects incorporate green space with trees, shrubs, and flowers into our park and playground design. These elements provide shade, enhance aesthetics, create a sense of tranquility, and foster a connection with the natural world. By immersing park and playground users in nature, landscape architects contribute to the overall well-being and enjoyment of the space.


We approach every park and playground project by prioritizing the needs of the community and the environment. The result provides outdoor spaces that promote physical activity, social interaction, and a deeper connection with nature.


Our commercial landscape planning involves designing and developing outdoor spaces for commercial properties. The goal is to create attractive and functional landscapes that enhance the overall experience for employees, customers, and visitors.


By performing a site analysis and considering key factors like functional layout, plant selection, and sustainability, our landscape architects can create landscapes that meet the needs of the property and provide an inviting atmosphere.


By carefully designing outdoor spaces, landscape architects can implement strategies to effectively manage stormwater runoff and reduce the impact of urbanization on the natural water cycle.

Our landscape architects design and incorporate various techniques to reduce the volume and velocity of stormwater runoff and control the quantity and timing of stormwater release. The goal is to prevent erosion, reduce the risk of downstream flooding, and ease the burden of stormwater infrastructure.


By integrating these and other stormwater management techniques into landscape design, our landscape architects can help mitigate the impacts of urban development and create more sustainable and resilient outdoor spaces.


When you work with McMillen Engineering on a landscape architecture project, you can be sure that it will exceed your expectations and meet all necessary regulations. We will carefully evaluate every aspect of your project to guarantee its compliance with local, state, and federal requirements. Additionally, we will work closely with you to understand your specific vision and objectives, then incorporate them into the design to create a customized solution for you.

McMillen Engineering, Inc. is committed to delivering exceptional results that meet regulatory standards and reflect unique preferences for your outdoor space. We can transform your outdoor spaces into aesthetically pleasing and functional places.
