I'm assuming you're talking about city or county-installed storm sewer inlets. The storm sewer is designed to handle the water on the roadway, which is what lands on the road and what adjoining land drains onto the road or the ditches on either side of the road. Stormwater engineers do calculations (if designed correctly) based on 100 year rainfall (sometimes 500 year) or other design criteria, which determines the size of the sewers and the size and number of inlets. Sounds like someone did a poor job designing your system.
Your house shouldn't be flooding, even if the storm sewer backs up a little. Do you have proper grade away from your house, which is 6" drop in the first 10' per the International Code? Do you have an operating sump pump? If either of these criteria aren't met, you've got a weaker case in my opinion.
You might have some recourse against the city or developer if you can show that their system is causing the problem. I would suggest video and photographs. You should draft a letter to the authority responsible for installation and upkeep of the storm sewers, requesting a meeting at your property to review the problem, and send it certified mail. I would suggest having an attorney and an engineer present if you can swing it.
