In addition to the new streets and alleys for the residential development, the redevelopment had very few available utilities. New sewer mains, water mains, electrical services, and telecom lines were routed throughout the site to feed the future residences. The improvements also included new street lighting, updated accessibility ramps and sidewalks, and landscaped parkways.
The land development project consisted of individual residential lots that would typically not require detention due to the size of each of the properties. In an effort to protect residents from flooding or other problems stemming from a sewer system at near capacity, and recognizing the potential offend by the porosity of the underlying soils TERRA proposed providing detention for the individual residences in a proposed green alley system. The system is ultimately maintenance free for the city and requires only minimal maintenance for the residences. While protecting the City from liability, the system reduces the capacity stress of the sewer, and provides superior protection for each resident by reducing flow to the combined sewers; the concept also reduces the City’s treatment costs.
