ORAM Metric 1

Metric 1 of the ORAM asks the rater to estimate the size of the wetland. As it can be seen from the ORAM Identification Sheet, the size of the wetland is divided into seven separate acre sizes. A helpful tip in completing metric one would be to relate an acre to the size of a football field. A football field, including both end zones, is 120 yards long. After converting this to feet, a football field is 360 feet long and 160 feet wide. To obtain the area of the football field in square feet, multiply 360 by 160 to get 57,600 square feet. The number of square feet in an acre is 43,560 square feet. Divide the number of square feet in a football field (57,600) by the number of square feet in an acre (43,560). This will give you a value of 1.3223..., meaning that there are approximately 1.32 acres in a football field. Alternatively, you could relate an acre to the size of a soccer field. There are approximately 86,400 square feet in a regulation size soccer field, so divide the number of square feet in a soccer field (86,400) by the number of square feet in an acre (43,560) equaling 1.98 acres in a soccer field. Compare the wetland you are currently trying to score to a size of a football field. This will help produce a more accurate score of the wetland.
