I need to use a box blade/scraper on my property to change how the rain water flows over some sections of my property. Here is my problem: When I look at my land it would appear to be pretty flat & level, which it is. However when it rains I have areas that will bring down a steady heavy flow of rainwater across some areas of my property & I would lile to box blade these areas to redirect the water flow. But because the land surface appears to be flat to the naked eye, I really need to map out the various elevations so I can redirect water flow. Problem is I don't know what to use to do this surveying work, or how to use any type of laser survey equipment to measure these small differences in the ground contour.
Can anyone advise me on what I need in the way of survey tools & how difficult this could be. Im not looking to invest in expensive survey equipment. Im thinking maybe something I can pick up from the Harbor Freight or Northern Tool store would do the job. And then there is the learning how to use the tools. Again, the contours & the height variation on my property is almost impossible to see, but when it rains, it really gives you a map of the land contours/pitches that I need to change to fix runoff water problems. Please share your experience & advice with me if you can. Thanks-Maddog
