The culverts under the proposed Connector Road extension over Powell's Creek must be in general accord with the attached Concept Plan titled "Pleasant Green Subdivision Special Use Permit Plan" (the "Plan") prepared by Collins Engineering with a revision date of March 2, 2020. To be in general accord with the plan, development must reflect the general size, arrangement, and location of the culverts, as well as maintaining no increase of the 100 year flood elevation outside of the Pleasant Green property. Modifications to the plan that do not conflict with the elements above may be approved subject to the review and approval of the County Engineer. 2. Prior to final road plan approval or permitting of a land disturbance in the floodplain, the applicant must obtain from the Federal Emergency Management Agency (FEMA) a conditional letter of map revision (CLOMR, or CLOMA), and prior to road acceptance the applicant must obtain from FEMA a letter of map revision (LOMR or LOMA). In addition, the applicant must copy the County Engineer on all correspondence with FEMA. Construction and installation of the culverts must be in compliance with approved road plans and FEMA approved CLOMR or CLOMA. 3. Any residential lots and associated streets resulting from the subdivision of the property, with the exception of the stream crossing and roadway identified on the attached plan as Connector Road, must be located outside of the 100 foot stream buffer, Flood Hazard Overlay and preserved slopes on the property. Lots may be permitted to be located within the landward 10 feet of the 100 foot stream buffer only if the lots are adjacent to approved stormwater management facilities located within the landward 50 feet of the stream buffer. Approval of lots located within the stream buffer must be subject Subdivision Agent approval. 4. The net density of the property must not exceed 6 units per acre, in accordance with the Crozet Master Plan. Net density must be calculated by subtracting the area within the Flood Hazard Overlay District, the 100-foot stream buffer, and areas of preserved slopes from the total acreage of the property subject to the special use permit. 5. Prior to issuance of a grading permit to allow installation of the stream crossing or with submittal of the final subdivision plat, whichever comes first, the applicant must submit an easement plat dedicating to the county the area identified for a greenway trail on the attached plan. 6.
