Just curious if anyone has any experience creating their own storm water management plans?
I own a 10.55 acre farm field in PA where I'm looking to put down a large gravel pad. I will use the pad to park portable storage units to rent. In this town, if you want to put a gravel pad down that exceeds 5,000 square feet you need a storm water management plan. Luckily, the field is already quite flat.
I'm having a survey done on the property, so I will have that to work from. Engineering quotes were outrageous for creating the plan and if I understand correctly I don't think they are rocket science.
The founder of Spanx was able to figure out a way to write her own patents, so I'm hoping I can figure out how to create my own storm water management plan for putting down a basic gravel pad.
How much time do you have to learn about runoff? If you want to learn about the engineering, I'd say go ahead. You can learn, file, pay fees, get rejected, re-apply as many times as you want.
Just because it doesn't appear complicated, doesn't mean its easy. There is still plenty of math calculations here...

There are a lot hoops to jump thru and you could be jumping thru the wrong ones. City, county or state regulations may all be different as you need to know which ones apply. Pay to have the work done. There is a lot of behind the scene phone calling that takes place. The stormwater plan may need to be submitted by a licensed civil engineer too.
Example...
Replacing side walks on a city property that is out side the city limits just added 2 weeks to the project. Falls under state jurisdiction not county. The client wanted to meet the Cities requirements.
Thanks guys. Yeah I’m usually all for paying the expert and I will eventually in this case, too. However I purchased the land for $65k and I wasn’t expecting another $30k just for the permits/plans to put down a gravel pad. That’s just my fault for not further researching up front.
Really, what sparked this is I was hoping I could do enough to get greater than 5,000 square feet on my own so I could get some units on the property. I already have an existing business and units ready to be placed so if I could get 40-50 units rented it would be nice to have that income as I prepare for the larger development costs to come down the road.
I hope to build a much larger pad where I will need additional permits and then eventually actual self storage buildings.
If I stay under 5,000 square feet I don’t need a storm water management plan, which may be what I do to get started, however this is much smaller than the 52,000 square feet I was planning to start with.

Every jurisdiction I have dealt with the SWM plan must be stamped by a licensed engineer. I am not aware of any jurisdiction that will allow you to do it on your own as you must first start with a survey and grading plan and then the engineer will determine best practical methods for the stormwater. Depending on size of lot and # of structures and impervious surface these typically are not cheap
I think Chris hit the nail on the head. I've seen hand sketched site plans approved but these calculations are much more involved. Not only will an engineer do it right, you are probably dead in the water without one.
Nick Heil I do this for my day job so it makes me cringe a little.
You can find templates online. I would try and take a stab at this. Some agencies just want to see the boiler point stuff in there and make sure you are not acting with out compete disregard for the environments. But you could be unlucky and have to be extorted by the system.
Sorry it’s part of the game.
Thanks @Lane Kawaoka. It certainly makes me cringe as well. I'm not trying to discredit or devalue what you guys do, definitely worth every penny.
With this property I fully intent to use engineered plans in the future as I build self storage and boat & RV buildings. I was just hoping I could avoid that sort of investment initially to just put down a large gravel pad (on what is already a rural piece of farmland) for my existing portable storage business to get some quick income going on the property and use that income to invest in the property further.
This may be a silly question, but if it's a cost thing in the short term...could you build multiple pads < 5000 sq ft and avoid the engineering costs/permits?

Hi Matt, great question! I thought if that too, but unfortunately it’s cumulative so even if they were separate and did at different times they look at the effected square footage on the entire property so I can’t get away with that.
if you are planning all these buildings and a parking lot . Pay the engineer to do the plan to encompass the entire project . Then you are only paying once .
Unless you have equipment , just wait till you see the cost of the dirt work . Big $$$
