SUBURBAN RES Team 19187 Competition Submittal

  1. 1. team<br />19187<br />Low Impact Development Design Competition<br />Suburban Residential Design Challenge<br />
  2. 2. What if Ventana Lakes <br />became<br />
  3. 3. Project Overview<br />Fundamental Principles<br />Walkable — To create a walkable, livable suburban community that celebrates the boulevard as an activity center, rather than just a vehicular path to residents’ personal garages. <br />Main Street/Boulevard — Schools, community centers, and a town square punctuate the boulevard, or “Main Street,” at prominent locations.<br />Site/Rain water prominence — Embrace the native plant species and enhance the natural drainage on the site by designing rain gardens or bioswales that lead to a larger, central waterway, also an activity node.<br />Early analysis of the typical suburb indicated to us that the model of winding streets and cul-de-sacs was not conducive to creating a pleasant neighborhood. So in designing Waterleaf, we borrowed key planning concepts from some of Houston’s oldest neighborhoods such as the Heights, Tanglewood and West University, as successful examples of Livable Communities.<br />Some of the elements Waterleaf borrowed from these neighborhoods include gridded street patterns organized around boulevards and avenues that become activity centers and the concept of schools and community centers at prominent locations within the grid.<br />We quickly found that the efficiency of the gridded layout allowed for large areas of open space that could be used for parks. These boulevards and the central park area also became integral to our concept of runoff micromanagement and Integrated Management Practices. Our diagrams clearly show a system of shallow grassy swales at the smaller streets that lead to rain gardens or bioswales at the esplanades then to the detention areas – the lake features - and then to the regional drainage way, all meant to minimize impact on the regional floodplain.<br />Limitations of the site — namely two diagonal pipe easements — are turned into positives by lining them with grand boulevards and walking and jogging trails. The commercial sites are relocated from corners of the site to a consolidated central Main Street feature at the entrance to the development.<br />The Blue Waterleaf is indigenous to the coastal prairie<br />

  5. 5. Ease of travel within community
  6. 6. Increased feeling of community
  7. 7. Grids are less prone to traffic accidents</li></ul>The Heights<br />West University Place<br />
  8. 8. Planning Concepts<br />Esplanades become parks for recreation and socialization<br />Drainage easements become parks and organize the development<br />
  9. 9. Planning Concepts<br />Lot A: 70 X 125 – 209<br />(15 extra)<br />Lot B: 60 X 115 – 664<br />(2 extra)<br />KISD Site<br />Lot C: 50 X 115 – 315<br />(1 extra)<br />Central Park is a connective recreational water retention area<br />KISD Option Tract<br />Esplanades in boulevards are 50 ft wide and contain rain gardens and jogging paths<br />Bayou Park, containing drainage easement with surrounding street, becomes an “Allen Parkway “ like recreational area<br />Major east-west street follows and minimizes pipeline’s affect<br />Major north-south street is more direct and is the major entry going through the Town Center<br />Internal perimeter street becomes buffer, as house lots do not front or back up to surrounding streets<br />Town Center is the main entry to the development and heart of the community<br />Recreation Center and Elementary School are part of the Town Center<br />KISD Option tract is contiguous and more valuable for future sale <br />KISD Detention pond is in a better location for connection to drainage<br />

  13. 13. A Form Based Code for WaterLeaf<br /><ul><li> Form-based codes foster predictable built results and a high-quality public realm.
  14. 14. These codes use physical form rather than separation of uses as the organizing principle for the code.
  15. 15. They are adopted into city or county law as regulations, not mere guidelines.
  16. 16. Form-based codes are an alternative to conventional zoning.</li></ul>Link to Form Based Code<br />
