You should clean and maintain culverts to prevent blockage. Culverts have an important function in a storm water system. Culverts help move water under a roadway or other structure that would otherwise have to go over or around the structure. Therefore, it is important to keep them clear of blockages so the water can freely move through them.
Also, if you are considering a project that requires a culvert, it is important to use the right size pipe to allow the water through. Pipes are expensive, so it may be tempting to use the smallest pipe that you think you can get by with. However, it is even more expensive to use the wrong size pipe and have it fail in the future. Then you will be purchasing a bigger pipe, as well as the costs of repairing the failed structure.
Boundary surveys establish the limits of your property. One of the biggest legal reasons for boundary surveys is to establish property lines so that you do not encroach on neighboring property. Encroachment can become a financial problem, especially if permanent structures are encroaching on someone else's property. In subdivisions, knowing your boundary lines allows you to build a fence or erect a structure in your property without fear of encroaching on your neighbor and legal action ensuing. Also, driveways can be built without fear of encroachment.
Boundary surveys are sometimes required for land and other transactions so that the exact limits and size of the property is known and recorded. The boundary description is written in the deed and recorded in the county courthouse for legal record.
Engineering can be strictly about providing a technical product, and many engineers can provide the product. However, it can also become a relationship where the engineer advises you on issues that you need technical knowledge of. In this case, it is important to find an engineer that you work well with and can establish a relationship with.
There are many factors that go into a property survey.
