In this particular case, assuming a straight roadway and equal zones, the first one will contain 50 per cent. of 10,560 = 5280 front feet. Since the actual area of the zone is 1 square mile = 640 acres, there are 5280 ÷ 640 = 8¹⁄₄ front-feet per acre in this zone. The table will show similar results for each of the four zones: ----+------+--------+----------------------------------- | | | Front-feet for varying acreages | | Front +-----+-----+-----+-----+-----+----- | | feet | 1 | 10 | 20 | 40 | 80 | 160 Zone|Weight|per mile| acre|acres|acres|acres|acres|acres ----+------+--------+-----+-----+-----+-----+-----+----- 1 | 50 | 5280 |8.250|82.50|165.0| 330 | 660 |1320 2 | 25 | 2640 |4.125|41.25| 82.5| 165 | 330 | 660 3 | 15 | 1584 |2.475|24.75| 49.5| 99 | 198 | 396 4 | 10 | 1056 |1.650|16.50| 33.0| 66 | 132 | 264 ----+------+--------+-----+-----+-----+-----+-----+----- As an illustration, suppose two taxpayers have farms of exactly the same size, 800 acres each, but placed differently in regard to the road, see figure below. Their influences or petitioning power may be calculated in front-feet from the preceding table thus: [Illustration: ASSESSMENT INFLUENCE Two farms of the same shape but situated differently with regard to the improved highway have different “petitioning influences” and are assessed differently for improvements. Farm _A_ is in contact with the road for 5280 ft., and has an influence or assessment value of 4158 front-feet. Farm _B_ is in contact 1320 ft. and has an assessment value of 2442 front-feet.] ----+------+----------------+---------------- | | Farm A | Farm B | +-----+----------+-----+---------- | | |Influence | |Influence Zone|Weight|Acres|Front-Feet|Acres|Front-Feet ----+------+-----+----------+-----+---------- 1 | 50 | 320 | 2640 | 80 | 660 2 | 25 | 240 | 990 | 160 | 660 3 | 15 | 160 | 396 | 240 | 594 4 | 10 | 80 | 132 | 320 | 528 | +-----+----------+-----+---------- Total | 800 | 4158 | 800 | 2442 | +----------+-----+---------- Contact Feet | 5280 | | 1320 -----------------+----------+-----+----------
