§ 9.232.070 Special provisions.
A.
Maximum Development (See FTSP pg III-28 sec 5.2). The maximum number of dwelling units permitted within this district shall be five dwelling units. In no case shall this maximum be exceeded. It is in no way intended or implied that the maximum number of dwelling units permitted is a guaranteed level of development. The ultimate number of dwelling units permitted shall be subject to approval by the Planning Commission in conjunction with a site development permit and/or area plan.
B.
All discretionary approvals shall be consistent with the following guidelines for the protection of resources:
1.
Oak Woodlands. Oak woodlands are defined as those general areas identified by a qualified biologist as having characteristics of an oak woodland plant community and are extensive enough to be considered habitat of local significance.
a.
Applicants for development proposals on parcels containing oak woodlands shall be required to provide a site-specific oak woodland analysis prepared by a qualified biologist/arborist to determine the precise boundary of the oak woodland. Said analysis shall include detailed mapping of at least one is to one hundred (1:100) scale.
b.
Oak woodlands shall be preserved in an undisturbed state to the greatest extent possible while still allowing for reasonable development. The site-specific analysis shall identify the level of impact of the proposed project and methods of reducing or avoiding adverse impacts of the project. The impact analysis shall consider all forms of disturbance resulting from the development, including changes in runoff, impacts within the drip line of trees, etc. If oak trees are proposed to be transplanted, the analysis shall identify suitable locations for the transplantation of oak trees.
2.
Streambeds. Streambeds are defined as major streambeds shown as a blue-line feature on USGS Quadrangle maps and/or Thomas Guide maps.
a.
Applicants for development proposals on parcels containing streambeds shall be required to prepare a site-specific streambed analysis prepared by a hydrologist to determine the precise boundary of the streambed. Said analysis shall include detailed mapping of at least one is to one hundred (1:100) scale.
b.
Applicants are required to submit detailed, site-specific analyses to identify direction and flow of natural runoff from the site, or immediately adjacent to the site. The detailed, site-specific analysis shall address the need for mitigation measures to keep velocities close to pre-development levels.
c.
All development shall minimize discharge so that future storm flows do not significantly exceed existing flow levels.
