6-70-40 Criteria For TDR Transfers

(a) Criteria for Sending Sites

Legally Created Lot or Parcel
- A Sending Site shall be a legally created Lot or Parcel.
Eligible Sending Sites
- Eligible Sending Sites are specified in Sec. 6-70-20(a). TDRs may be severed and sold from Eligible Sending Sites if the land is subject to a conservation easement granted to Pitkin County in a form approved by the County after the 5th of July, 2006 but before the TDRs have been certified provided the conservation easement specifically reserves the right to certify TDRs. The County, in its discretion, may refuse acceptance of the conservation easement. If the landowner seeking a TDR claims State or Federal Tax benefits for the conservation easement, the landowner must declare any TDRs reserved as an amount received for a bargain sale at their appraised value on IRS Form 8283 signed by the appraiser and acknowledged by the County. TDRs reserved in a conservation easement may not be certified until the County duly executes a restrictive covenant on the property, and takes other action as may be necessary to rezone the property or to designate it as a constrained lot in order to designate the property as a TDR sending site.

3.Aggregation of Acreage

The acreage of all contiguous parcels in common ownership shall be aggregated for purposes of calculating how many TDRs may be severed from the Sending Site.

4. Restriction on Further Development

Upon severance of a TDR from a Sending Site, the owner of the Sending Site shall execute and record a restrictive covenant on the parcel that acknowledges that the development right has been severed from the parcel and that all further development, as that term is defined in Chapter 11, is prohibited. The form of the covenant shall be approved by the County Attorney, and shall address (a) what types of activities not involving structures or regular human occupancy may still be conducted upon the land following severance of the TDR, and (b) obligations regarding maintenance of the land (including weed control and fence maintenance) following severance of the TDR.

5. Criteria for Retaining Structure in RR Zone District

- (a) The structure must pre-date the re-zoning of the parcel to the RR zone district;
- (b) The structure must be on a least thirty-five (35) acre parcel, or must be on a legally created separate parcel that is substandard in size. Subdivision shall not be permitted to create parcels less than thirty-five (35) acres in size;

- (f) The structure may not be subdivided, separately conveyed or otherwise separated from the underlying preservation site.

6. Criteria for Transfer of TDR From a Lot or Parcel Containing Less Than One Acre Within the RR, TR-1 or TR-2 Zone Districts
