Sending site notes

Sending Sites are properties where TDRs have been transferred away from the property. Future development is restricted at Sending Sites. Some sending sites are single parcels, and others comprise many parcels. Sending site marker points are placed at the approximate center of one of the central parcels of the entire sending site property.  The Sending Site Property layer shows the property boundaries of all parcels associated with a single sending site (turn on or off layer by clicking the check box under Add/Draw Layers pane). The pop-up window (shown by clicking a site marker) shows data about the sending site, including the total number of parcels, total acreage and zoning of the sending site. Learn more about TDR Sending Sites.

Receiving site notes

Receiving Sites are properties that have used TDRs to develop additional lots, units, or square footage. Receiving site marker points are placed at the approximate center of one of the central parcels of the receiving site where TDRs were used to increase the number of units or square footage associated with a receiving site. The parcel on which the marker is located is not necessarily the only parcel that “used” the TDR(s). This is particularly true in Plat developments (subdivisions into more than four lots). In many cases one or more TDRs were used at receiving sites to increase the total number of units allowed in a subdivision. The “Receiving Site Properties” layer shows the boundaries of the entire development project wherein TDRs were applied (turn on or off layer by clicking the check box under Add/Draw Layers pane). The receiving site pop-up window indicates the number of additional units, lots, or square footage obtained in the development with TDR. Learn more about TDR Receiving Sites.

King County TDR Bank

The King County TDR Bank Site is not a true “site” (the icon is placed at the King County TDR Program offices). The King County TDR Bank provides a mechanism for King County to facilitate the private TDR market and bridge the time gap between willing sellers and willing buyers of development rights. The TDR Bank buys, holds and sells TDRs from private parties to facilitate inter-jurisdictional transfers of development rights – i.e., county-to-city TDR. The “Highlight Site Connections” in the TDR Bank pop-up window shows the sending sites from where the Bank purchased development rights. Learn more about the King County TDR Bank.

Site connections

The arrows connecting sending sites and receiving sites in the TDR Property Map show the origin of TDRs used at receiving sites. All receiving sites will have at least one site connection arrow. Sending sites may or may not have a site connection. Even if no site connection from a sending site exists, some development rights have been transferred from the sending site, and future development at the sending site is restricted by the terms of a conservation easement.
