Not sure if this is a national, state, or local ordinance, but here where I am they are fixing to require that retention ponds be inspected on an annual basis. This means that they will be cracking down and keeping them mowed and digging out the silt that has washed in. Our storm water people often require these ponds at commercial and new subdivision sites to compensate for the run off of roads and parking lots. Anyone have experience with this? My brother works for a grading/site company and we have discussed "partnering" up on the work. I have the mowing equipment and he has the dozer and dump trucks. How do you figure your bids?
