The New York State Standards and Specifications for Erosion and Sediment Control has three sections dealing with E&S measures:

Section 3 Vegetative Measures
Section 4 Biotechnical Measures
and Section 5 Structural Measures
I think it is pretty...
Specifics of the original question, local requirement, and legal standing apart, it is an interesting philosophical question as to the point of the rule.
One reason being that the municipal stormwater system is usually the downstream property. The stormwater system is not only the manholes and...
I've seen this a lot. Pre-development means pre-development. Not pre-your-development. The owner should address it the same way as if it was in fact a new development, with on-site storage, bioretention areas, etc. Just because the previous owner got away with not meeting the standard for...
Here is a puzzle that I've worked at for a while with out much result. Take profile station-elevation data, in this case stream profile data cut from a less than perfect LiDAR source, and filter the data such that only local minimum ordinances are left resulting in a station-elevation series...
Actually makes sense to me. With all sections equal in diameter, the system drains only as fast as gravity can pull the water out. Energy loss through any section is proportional to its length. However, when the middle section is smaller in diameter, water is being pulled through it faster...
I think the rule and TR-55 is more accurate than you give it credit. Albeit it is an oversimplification as most regulations are in order to be dummy-proof, and the reviewer doesn't know quite how to articulate it.
TR-55 states: "The watersheds must be hydrologically homogeneous, that is...
You might have luck with the USGS groundwater monitoring sites:

Look for a site screened in the surficial aquifer. There are a bunch in the Naples region. It would probably be best to find 3 or 4 that surround your property and take an average...
No central source. You would have to go to each states licensing authority and check if there is a licence option for SE, or Structural Engineer. I don't know the full list (CA and IL are the only ones I can name), but it is typically in states that have somewhat complicated building codes...
I agree with you on a basic level. The reason most people love engineering is the opportunity to do new things and work on new and different projects.
Again, flip side, if you ever feel pressured to provide design services outside your comfort level, or told to stamp something you're not...
If the new task is in your area of expertise, and uses skills you already have mastered. i.e., If you are a geotechnical engineer and have mastered basic geotechnical principals, you may be able to successfully design a pipeline foundation even though you've never done that before. I would...
For typical dam breaches the default is the free unsteady-state USACE HEC-RAS, there is a breach component to it. But, there are many other proprietary and free programs/methods you can use depending on the situation and purpose of the study, some simpler, some more complex.
You certainly can develop a hyetograph directly from an IDF curve, its called a frequency rainfall distribution, completely unrelated to the SCS distribution, and Trackfiend is on the right track, he just needs help working through excel functions, not the hydrology. The idea is to have the 1...
HEC-HMS takes the Lag Time as input. Not the Time of concentration. I don't know about PondPack. This could be the issue if PondPack takes Time of concentration and you entered the values identically.
