  • 6th Avenue Corridor

    November 21, 2014

    Confluence is developing pedestrian friendly, artistic and sustainable corridor improvements to revitalize this historic area of Des Moines.

    · view full ·
    • Confluence, together with the City of Des Moines and the non-profit 6th Avenue Corridor, recently presented the conceptual design for the 6th Avenue streetscape to area residents, stakeholders, and the public. Participants viewed renderings and plan graphics for the corridor and also offered thoughts about the progress to date. In the coming weeks and months, Confluence will continue to refine the design in preparation for a joint effort with the City of Des Moines to develop a series of phased documents to begin construction in the corridor.

      Design components include:

      • Implementation of a “road diet” to better suit multiple modes of transportation, including walking, biking, and vehicular traffic. Currently a 5-lane roadway within 60-66’ right-of-way, the diet proposes to reduce the number of lanes to three (including one two-way-left-turn lane) to widen pedestrian space on both sides of the corridor.

      • Integration of green infrastructure at intersections to capture and filter storm water prior to entry into a newly updated storm sewer system.

      • Installation of public art at intersections and other key areas to tell a cultural or historical story of 6th Avenue and the surrounding neighborhood.


  • Kettlestone Design Guidelines

    August 19, 2014

    Confluence is currently developing Design Guidelines for Waukee, Iowa’s new Kettlestone District.

    · view full ·
    • After developing the Kettlestone Master Plan, Confluence has been retained to assist Waukee in the preparation of development guidelines and standards to guide development of approximately 1,300 acres of development known as “Kettlestone”. The project is intended to add 7,000 new homes, apartments and townhomes; 5.5 million square feet of office space and 3.8 million square feet of retail space to the area.

      In addition to the design standards, Confluence will assist the City in review of development proposals for plan compliance as they are received. Confluence has also been retained to assist in the formation on overlay zoning districts and to provide suggestions as necessary for development plan submittals to maintain the vision set forth in the master plan.

      This summer, downtown Sioux Fall’s Main Avenue is going on a diet to improve the pedestrian experience. One driving lane and the parallel parking stalls have temporarily been converted to diagonal parking stalls. This reconfiguration adds 80 parking spaces, shortens pedestrian crossing distances and creates space for pedestrian amenities including benches, planters, public art, trees, and more. Midblock platforms also have been installed to provide additional public seating and dining spaces.

      This pilot project is the first of its kind in Sioux Falls and is, in part, in response to recent public input. Throughout the installation, the City will seek public input on the “road diet”. Depending on the results, permanent changes could be implemented in the future.
