Storm water civil engineer

As related to the article in the Maryland Gazette and the Channel 11 i-Team story, I am involved in a lawsuit with Anne Arundel County and K. Hovnanian Homes over stormwater runoff. We bought a foreclosed home for our family, which includes 4 boys, that is in a low area. We have had 2 of our sons bedrooms flooded with stormwater and some of their personal things ruined. We had a home inspection but it was dry at the time and there were no open complaints with the county. As we quickly realized, Anne Arundel County is collecting stormwater from roadways and discharging it at my property line. In addition, K. Hovnanian built 31 new single family a few hundred feet from my property. All the water collected from this new community is discharged in the direction of my property.  The county told K. Hovnanian the plan they had designed for stormwater would flood my property but K. Hovnanian continued with construction as planned.
I believe the County and K. Hovnanian thought they would have the money and resources to fight off any lawsuits because that would be cheaper than correcting the stormwater management issue. It leaves residents with no options and no recourse. This case is bigger then just my issue. I am not the first to have new development flood their property. Builders have been left unchecked and a message needs to be sent to avoid future issues.
I am fighting this lawsuit myself. It takes a lot of money and time. We are not rich and we do not have thousands of dollars to spend fighting for our home and future. I cannot afford an attorney. I am asking for money to cover the cost of a civil engineer. This will allow me to have an expert witness in court. It is not easy to find a civil engineer who will testify against a major homebuilder or the county. I have had to put out a lot of money to take the suit this far. This is in addition to money lost due to a flooding basement and yard. I have lost countless hours of work pumping out our basement. There were nights when my sons and I had to take turns every hour waking up to watch the water levels and remove water. We have replaced carpet, padding, furniture, lawnmowers, weedeaters, and dirt that has washed away. We have to pay for a mosquito service just so our dog is able to go outside.
The support I have received from neighbors, people with similiar issues, and the stormwater coalition group in Anne Arundel County has been amazing. Thank you to everone who has taken an interest in my story. No amount is too small. I hate asking for handouts but this is the only way I can hire an expert. I can fight yhe suit but I cannot testify as an expert.
