Select 'Pre-Construction Condition' by 'Cowardin System' and 'HEA Category'. Then enter 'Acres' 'Existing Functional Value' (0 - 1) and 'Proposed Functional Value' (0 - 1). Finally select the following controls sequentially from left to right. Note: 'Incremental Annual Return' and 'Capitalization Rate' are set at a default of 3.3%, but these can also be manually changed at users' discretion.
