  1. South West Study AreaIntroduction • Summary of Study Area • Unified Development Code Amendments • Points of Interest • Staff Recommendation • Review Schedule of Meetings

  2. South West Study Area • Area generally bounded by Highway 59, Hwy 36, Hwy 190 the Tchefuncta River, the Tangipahoa Parish Line and Lake Pontchartrain • From the eastern edge of Mandeville to Abita Springs to Goodbee to Madisonville • Four quadrants created by I-12 and the Tchefuncta River

  3. South West Study Area

  4. Points of Note • The South West Study Area has undergone similar pattern of development but on three different timelines • Older areas of the southeast and northeast quadrants have long established development patterns • The southwest quadrant underwent a dramatic increase in development pressures in the late 1990’s • The northwest quadrant has undergone an increase in development pressure in the last 5 years

  5. Points of Note • The northwest quadrant has undergone an increase in development pressure in the last 5 years • Each distinct growth period has had different standards of development and infrastructure requirements • This ordinance and other recently adopted standards are an attempt to improve on the previous requirements

  6. Existing Land Use

  7. Points of Note • Density should be assigned to areas where infrastructure can be constructed without having a significant impact upon the adjacent communities • Higher density development should be placed in areas which are less susceptible to catastrophic impacts of tropical storm events. • Due to an increase in elevation, I-12 is the traditional line of evacuation for St. Tammany Parish

  8. Elevation

  9. St. Tammany Greenprint

  10. Commercial Centers and Town Centers should be separated so as not to strip out commercial corridors • Industrial or Heavy Commercial centers must be placed where adequate highway infrastructure can be built if not already available

  11. Commercial and Town Centers

  12. Proposed Zoning Pattern

  13. South of Interstate 12 • South of I-12 is either heavily developed with established development patterns or undergone considerable developmental review in the last ten years • These existing developments have established a relatively consistent pattern of development both east and west of the Tchefuncta River • Environmental issues and physical barriers limit the developmental capacities of the southern half of the South West Study area • The threat of tidal inundation by storm events suggest that concentrations of higher density should be avoided

  14. South of Interstate 12 • Commercial activities should be located concentrated at existing centers at Mandeville, Madisonville, and interstate intersections. • While some concentrations of density exist, any additional residential development south of US 190 should be of lower density. • Some small scale existing commercial will remain, particularly along Louisiana Highway 22.

  15. Staff RecommendationSouth of I-12 • Approximately 79% of property designated residential (A or E Districts). • Approximately 21% of property designated commercial, institutional or mixed use. • Density of all Residentially Zoned Property (A or E Districts) is 1.40 units per acre. • Density of all property is 1.11 units per acre.

  16. Southeast Quadrant

  17. Southwest Quadrant

  18. North of Interstate 12 • The relative lack of development would normally permits planning and construction of transportation, drainage and other infrastructure. • However, environmental issues and physical barriers limit the developmental capacities of the northwest quadrant of the South West Study area . • Towns, crossroad communities and the interstate intersections form the “Commercial and Town Centers” in this area. • Existing centers should be developed with growth focused around these existing centers.

  19. North of Interstate 12 • Areas along the Tchefuncta River and west of Louisiana Highway 1077 (north of U.S. 190 and Bedico Creek (between U.S. 190 and I-12) are particularly sensitive. • Significant acreage of environmentally sensitive property located north of I-12 should be designated as lower density districts. • While concentrations of higher density are more appropriate north of I-12, these must be located within relatively limited areas which are not as environmentally sensitive.

  20. Staff RecommendationNorth of I-12 • Approximately 80% of property designated residential (A or E Districts). • Approximately 20% of property designated commercial, institutional or mixed use. • Density of all Residentially Zoned Property (A or E Districts) is 1.20 units per acre. • Density of all property is .96 units per acre.

  21. Northeast Quadrant

  22. Northwest Quadrant

  23. Staff Recommendation • Approximately 79% of property designated residential (A or E Districts). • Approximately 21% of property designated commercial, institutional or mixed use. • Density of all Residentially Zoned Property (A or E Districts) is 1.31 Units per acre. • Density of all 95 square miles is 1.04 units per acre.

  24. Review Schedule of Meetings • Special Public Hearings • October 21, 2008 • November 18, 2008 • Presentation to Council in December for additional hearings as needed by Parish Council prior to adoption
