Generally, there are two types of Conservation Subdivision designs that are permitted under the LPHCP—low density, large-lot designs and higher density, clustered designs. Low density, large-lot designs require:
- 10-acre tract size minimum
- Subdivision infrastructure (e.g., paved roads, utility corridors) and community common areas (e.g., clubhouses, playing fields) may not exceed 10% of the total subdivision area
- Minimum lot size of 3 acres, with the average lot size being 5 acres
- Up to 20% of each lot used for single-family residential purposes
- Location of residential use area is at the discretion of the individual lot owner
- At least 80% of each individual lot must be permanently protected for the benefit of the Houston toad
- Individual lot owners are responsible for management of toad habitat areas
Higher density, clustered designs require:
- 20-acre tract size minimum
- All development included within a single, contiguous area
- Developed areas, including all subdivision infrastructure, may initially include no more than 20% of the total subdivision area; the developed area may increase to 30% over time, with provisions
- Single-family and multi-family residences
- One dwelling unit per 1 acre; over time, land added to the developed area may include one dwelling unit per 0.5 acre
- Property Owner’s Association is responsible for management of toad habitat areas
The requirements for permitting a Conservation Subdivision include the requirements for all subdivision development, which are outlined in Section 3.5.1 of the County of Bastrop Subdivision Regulations. In addition, however, Conservation Subdivisions require areas set aside and actively managed for the protection of the Houston toad.
Since the protection and management of Houston toad habitat is required, there is no mitigation fee for a Conservation Subdivision Certificate. There is, however, an application processing fee of $1,500 in addition to the standard subdivision application fees.
