Sensitive Design

Nilles Associates, Inc. (NAI) takes great pride in being at the forefront of sensitive design by applying the concepts of green infrastructure and low-impact design to several residential, commercial and municipal projects. 

These concepts have been used as guides during project planning to protect valuable resources such as mature trees, open spaces, wetlands, or sensitive watersheds.  They have also been used to develop designs to improve storm water runoff volume and quality control.

Sensitive Design Services include:
Master Planning:
Several steps are involved in using conservation or
low-impact design concepts in master planning efforts:
● Identification of key natural resources and sensitive
    areas to protect 
Existing creeks, streams, lakes, rivers, wetlands, etc.
● Designation of buildable area where construction
    can occur
● Project construction access area where construction
● Develop master plan for buildable area
● Consider terrain, soils, other information to develop
    a plan that provides desired design goals while
    limiting impact to site and surrounding

Storm Water Design:
The principles of conservation design have many benefits, including:
● Reduction of storm water runoff peak flows and
● Increase of storm water infiltration and ground
    water recharge
● Improvement of storm water quality through
    interception of pollutants conveyed by storm water
● Limitation of erosion, sedimentation, and other
    damage caused to receiving waters
NAI used these principles in the design of several residential and commercial sites.  Detailed plans for these sites have included design of features such as rain gardens, stone weepers, level spreaders, bioswales, and other best management practices (BMPs). These practices demonstrated quantitative benefits of their inclusion through use of advance computer storm water modeling software based on NRCS TR-55 method.
