TND WITH A TWIST: TRADITIONAL DESIGN MEETS SUSTAINABILITY ![]()
SUSTAINABLE SITE DESIGN: STORMWATER MANAGEMENT, STORMWATER QUALITY AND LANDSCAPE ARCHITECTURE General Capital will team with National Survey and Engineering, a division of R.A. Smith & Associates to serve as lead civil engineer for our project. National Survey is one of Wisconsin’s leading civil engineering firms, with in-depth expertise across disciplines including LEEDTM certified professionals. The National Survey team of landscape architects, land development engineers, planners and technical staff will design, engineer and supervise the implementation of a cutting edge sustainable site design for our project. The Madison Environmental Group, our Green Development consultant, will also contribute to the final site design. From a technical perspective, our approach to sustainable site design includes three elements: stormwater management, stormwater quality and landscape architecture. STORMWATER MANAGEMENT Sound stormwater management is critical both during construction and throughout the life of the development. As a site located in the City of Milwaukee, the 2.8 acre parcel must comply with Milwaukee Metropolitan Sewerage District (MMSD) stormwater run-off regulations as well as City of Milwaukee stormwater quality regulations. The development must also be designed to comply with federal and state stormwater pollution prevention rules (NR 216 and NR 151 are applicable sections of the Wisconsin Administrative Code that cover Construction Site Stormwater Discharge Permits through the Wisconsin Department of Natural Resources). We will use a series of Best Management Practices (BMPs) to create an effective stromwater management plan for this site. We will integrate BMPs to reduce erosion and sedimentation in runoff during construction. In addition, we will address long-term considerations for maintaining stormwater quality in a post-construction plan. Ongoing stortmwater management will include the use of devices such as bio-infiltration, reduction of impervious areas and underground detention. Techniques to be applied during construction include:
Working in concert with ARCADIS on the environmental side, our team will explore the following techniques to address stromwater runoff on an ongoing basis:
STORMWATER QUALITY Effective stormwater quality is a site design priority. Milwaukee stormwater quality regulations state, “For redevelopment, by design, reduce the maximum extent practicable, the total suspended solids (TSS) load by 40%, based on an average annual rainfall.” There are multiple devices available that can achieve this TSS removal rate including: below-ground sedimentation traps, mechanical devises (typically known as stormceptors) and bioretention devices. While all of these options will be considered, a bioretention devise is our preferred method to achieve a sustainable site. A bioretention system consists of a soil bed planted with native vegetation above a sand layer. Stormwater run-off entering the system is filtered first through the vegetation and then the soil/sand layers before being conveyed downstream through an underdrain system. These systems are designed to hold a shallow pool of water to allow for infiltration over time. Small overflow systems are often installed to limit ponding depth during large storm events. This design allows us to retain water on site while recognizing that environmental conditions may not allow us to practically install underground detention systems. A possible location for bioretention systems would be along property lines between the garages. Run-off from the rear two-thirds of each parcel, along with roof drains, would be directed into these areas. The alley could be crowned in the middle and designed to direct runoff into these systems. An underdrain system would be constructed to convey the treated water parallel to the alley way and into an underground detention facility, if ultimately installed. We recognize that an in-depth study of the most effective location and configuration must be performed. It is likely that the final design will involve a hybrid of systems, offering a higher degree of water quality assurance than a traditional system, but recognizing that a contaminated site offers its own challenges. LANDSCAPE ARCHITECTURE National Survey’s landscape architect will work closely with the civil engineer to ensure appropriate plant species are specified to achieve the project’s sustainability goals. For the initial construction, appropriate grass mixtures (low water mixes such as blue gamma, fescue and “no mow”) will be specified for all disturbed areas. Working in concert with ARCADIS and the Madison Environmental Group, the landscape architect will also specify appropriate species for all permanent features such as the bioretention system and phytoremediation zone shown on the site plan. In addition, to ensure continuity after the sale, a prototypical landscape plan and a list of preferred plant species will be developed and distributed to property owners. This plan will encourage the use of sustainable landscaping and establish the following:
Taken as a whole, our approach to site design will produce a high-quality, sustainable development that will serve as an excellent example and prototype for the City, JCI and the Riverwest neighborhood. APPROACH TO ENVIRONMENTAL REMEDIATION:
Our design addresses this issue by eliminating development on the most contaminated portion of the property (southwest corner) and creating a phytoremediation zone along the alley (see appendix). Soils excavated from the development areas will be placed on the reserve quadrant, which already contains the highest concentrations of constituents. This area will then be used as a small public pocket park with raised planting beds, a community tool sharing facility and additional phytoremediation area. |
SUMMARY RECOMMENDATION While detailed study and analysis must occur, ARCADIS has suggested the following plan for initial discussion purposes: ![]()
In summary, the environmental conditions can be managed under either a traditional or innovative residential site plan. However, the use of our innovative plan will provide opportunities to reduce the cost associated with the environmental conditions while still allowing the development to fit well into the Riverwest neighborhood. We are prepared to handle the Remedial Action Plan and necessary documentation through case closure in concert with JCI. Given our previous experience with brownfield redevelopment, Johnson Controls and the City can be assured that they will be working with a responsive, professional counter party that has done this before. We are committed to working with JCI to minimize the ongoing environmental liabilities associated with this site. GREEN DEVELOPMENT PRINCIPLES: THE GREEN BUILT HOME AND BEYOND Green building, eco-home, earth-friendly, sustainable. All compelling catch phrases. While the green building movement continues to catch on in Wisconsin, it should be clearly understood that “sustainable development” means different things to different people. Importing expensive recycled materials from Italy may appear “green,” but is certainly not sustainable. Our intent is to examine our project from as many angles as possible, then make responsible and sustainable choices. We will look at the project’s site design, solar orientation, building materials, building systems, construction process, ongoing lifestyles of the residents and ultimately how the project can contribute to Riverwest as a neighborhood. As a point of departure, we are committing to producing homes that will, at a minimum, receive the Green Built Home stamp of approval. This program, currently implemented by the Wisconsin Environmental Initiative and the Madison Area Builders Association, produces a baseline certification program specifically targeting residential development. Unlike LEED, the Green Built Home initiative is relatively simple to track, provides specific checklists relevant to residential construction and produces a certification that pushes the sustainable building and energy standards of new construction. We have included the checklist in the appendix of this document. To maximize the sustainable objectives of our project, Madison Environmental Group, Inc., will provide green development consulting services throughout the process. The following framework will be used to finalize civil and architectural plans, create construction documents and build a “guide book” for future residents of our project:
Our goal is to create a model development for JCI and the City of Milwaukee. We believe that this project can raise environmental and community awareness on a number of levels. We are committed to working with the City to further enhance our green development strategy as appropriate. |
