Villages and Small Settlements: Tamnaherin
Tamnaherin is located some 3 kilometres south of Eglinton village at the junction of the Tamnaherin and Brockagh Roads. The settlement is well screened from the Tamnaherin Road and has developed gradually over a number of years with the Church providing the main physical focus.
The Department has defined a development limit within which small scale development and further expansion of the settlement will be accommodated. When first identified as a settlement it was recognised that substantial new development might require the provision of a sewage treatment works. The completion of a new treatment works will help facilitate development in the settlement.
The settlement provides potential for single houses or in-depth serviced sites. Development proposals on larger parcels of land adjoining the development limit should include provision for appropriate landscaping treatment on the settlement boundaries.
