These can kill a project and in many cases explain why an infill lot isn't being developed6) Check CC&Rs to ensure that the neighborhood plan doesn't have any restrictions that apply to your project7) Check the Plat to ensure there are not special restrictions listed on it - These can be a gotcha as they aren't in the CC&Rs, but may still be enforceableNow you are ready to design which sets up a new list1) Foundation design - hire an engineer, soils and slope will impact the cost2) Retaining walls if you have a slope3) Water retention or drainage - If the lot is large enough you may need a water management plan on how to handle storm drain flow, check with your municipalityI may have left something out, and I am always learning, but this is my basic list.

I do epoxy floors and concrete polishing (Full Mechanical) and  I tell people all the time that the coating I put down is only as good as the surface it is applied to. 

I’m brand new to these forums and just scratching the surface of researching the real estate market in East Texas.

@Wayne Brooks could be correct if the easement really precludes building on the surface, but it might not.

Depending on how bad the surface is, I agree with @Christine Kankowski and I would go with basketball on one side and I like her idea for the wall on the other.

I understand there are outlier experiences, and while on the surface yours appears to be one of them, it may not be as uncommon as you think.  

If I can't do get rid of them, then it seems like I'll either need to get a new bathtub or re-surface it. 

You need to clean the shower doors and keep surfaces dry or mold will grow.

So far I have only scratched the surface of the BP goldmine of knowledge, & still gained a lot.All the best,Pam Dhillon

A sand mound doesnt replace the tank , it is a mound of sand that acts as a filter for the affluent , these are used in areas of poor drainage .
