Subject: Roseberry Ridge Estates, Addition # 1
Lot 6, Block 2 & Tracts A, B, & C
Number of Pages: 1 + Subdivision Plat
Lots on the subject subdivision have ample room for on-site wastewater disposal systems
placement. General boundaries have been drawn on the included preliminary plat. Future soil test
results may limit some of the useable area, if for instance high bedrock is encountered. Based on
slope; the potential wastewater disposal system area for each lot is estimated as:
Property
Total Area
Wastewater Useable Area
Tract A
663,400 Ft2
300,000 + Ft2
Tract B
493,000 Ft2
100,000 + Ft2
Tract C
415,000 Ft2
150,000 + Ft2
Lot 6, Block 2
132,400 Ft2
50,000 + Ft2
Private water well placement will not adversely impact these areas.
