"We have talked with the builders who supposedly checked the grading of our property which is apparently is normal."

Pooling of water is indication that there is a problem with the grading and is not normal, unless the pool is large enough to boat in. Ask the builder what method he used to check the grading, hopefully not wetting an index finger and sticking it up in the air. Tell him you get enough bullshit on the family farm and you do not need any more here. I digress.

I believe the builder has there engineers come out an look at it. Probably a stupid question, but who would I contact to come out and give me a second opinion?

A landscape architect or a good landscaper should be able to advise you and come up with a solution.

Do you have any pictures?

The International Residential Code (IRC) which forms the core of most statewide building codes requires grading to provide a minimum of 6" of fall within the first 10 feet of the home for drainage purposes.

The National Association of Home Builders publishes Residential Construction Performance Guidelines for Professional Builders and Remodelers. Some builders use it as a quality standard. It provides the following with regard to site drainage:

"To ensure proper drainage within 10 feet around the home, the contractor will establish necessary grades and swales within the property if the work is included in the contract. Standing water will not remain for extended periods within 10 feet of the home after a rain (generally no more than 24 hours), except in swales that drain other areas or in areas where sump pumps receive discharge. In these areas a longer period can be anticipated (generally no more than 48 hours). Water may stand longer during periods of heavy rains, especially when heavy rains occur on successive days. No grading determination will be made while frost or snow is on the ground or while the ground is saturated."

Your neighbors house could have been built on top of a spring. Do you have springs in your area? Springs run 24/7 in all weather in our area.

We don’t that I am aware of. We live outside of Denver, it dry here. We do have very clay soil, which could contribute.
I looked at our soils report and it doesn’t appear that we have a high water table.

So this picture was in May when we noticed this happening. Our builder at that time brought out a temporary drain to dry out the area. They were convinced that if they dried it out it would stay dry.
I didn’t see it as a permanent solution but accepted it at that time.

Of course my neighbors sump pump continued to run. The area is wet again and you can see the calcium deposits. It’s not currently a puddle but like I said we’ve really had no moisture and I’m concerned it will be a puddle again since we haven’t changed anything.
