A Time-Saving Tool for Stormwater and Drainage Analysis **Rating:** 5.0/5.0 stars **Reviewed by:** Kaitlin W. | Engineer 1, Small-Business (50 or fewer emp.) **Reviewed Date:** March 08, 2026 **What do you like best about GeoSTORM?** I really like how the program makes it easy to delineate sub-basins and automatically calculate their areas. When performing SWPPP analyses in CAD, this step can be very time-consuming, so it’s helpful to have a tool that streamlines the process and saves a significant amount of time. I also appreciate that the software automatically computes flow paths for determining time of concentration. This is another task that can take a considerable amount of time when done manually in CAD. Additionally, when calculating time of concentration values, the program allows you to base them on the site’s hydrologic soil properties, which is very useful. I also like that it provides a detailed breakdown of how the TC values are computed, making the process transparent and easy to follow. **What do you dislike about GeoSTORM?** One challenge I have experienced with GeoSTORM is modeling stormwater treatment, particularly when trying to represent pretreatment practices. At times, it can be difficult to configure the treatment components in a way that accurately reflects how the system is designed to function in the field. Because of this, I sometimes wish there were more flexibility to manually define or customize treatment processes within the model. For example, having the option to manually represent pretreatment elements, such as sediment forebays or other initial treatment steps, would make it easier to more accurately reflect certain stormwater management designs. While the existing tools are helpful, additional manual modeling capabilities or more flexible configuration options for treatment practices would improve the program’s ability to represent complex systems. **What problems is GeoSTORM solving and how is that benefiting you?** GeoSTORM streamlines many of the most time-consuming aspects of stormwater modeling and SWPPP analysis. Tasks such as delineating drainage sub-basins, calculating drainage areas, determining flow paths, and computing time of concentration can take a significant amount of time when performed manually in CAD or spreadsheets. GeoSTORM automates much of this process, which improves efficiency and reduces the potential for manual calculation errors. By integrating these calculations directly into the modeling workflow, the software allows me to focus more on evaluating stormwater management strategies and ensuring compliance with regulatory requirements, rather than spending excessive time on manual setup and calculations. This ultimately speeds up project development and helps produce more consistent and transparent hydrologic analyses. **Official Response from Sara Presta:** > Hello Kaitlin, Thanks a lot for sharing your review.

It is flawless... **Rating:** 5.0/5.0 stars **Reviewed by:** DAVID V. | President and Senior Water Resources Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** June 25, 2025 **What do you like best about GeoSTORM?** I have taken at least four courses on PCSWMM, and yet I still find it difficult to tackle some workflows. Geostorm is like working with a LEGO model, although I must agree with one previous reviewer that adding catch basins to the pipe instead of a model is quite awkward. That is a SWMM flaw, not a GEOSTORM flaw. Some other wrappers have worked around that, and with good reason. I believe that CivilGEO would like to cover all EPASWMM bases before tweaking the actual model, and that is completely understandable. You have to walk before you run, but my first work with GEOStorm was a gigantic solar farm that covered an entire town, draining to a river that was also modeled in GEOStorm. I tried Autodesk's Infoworks, and I don't understand why a flood model needs to look like a relational database. GEOStorm will be your best bet if results are what you are after. The problem with most of these other programs is that they fail to prioritize the user experience. If you need to gather rainfall, streamflow, terrain, land cover, and soil data before laying out your model, you are already a couple of days behind, and most importantly, you will be tired before you start modeling. See, I look forward to working with CivilGeo's tools. It is that engaging, and that in itself is a battle won. The most difficult part of any project is getting started, and CivilGEO's products invite you to do just that. When was the last time you were eager to work? You have to experience it, because you have three options; 1 - Work slowly 2- Have a battery of Python scripts that can pull all that data for you. (Good luck maintaining that library for a few users.) 3-Use Geostorm Five years ago, I wasn't sure if I would continue with my career in water resources. I was getting tired and bored. CivilGEO is one of the main reasons that I continued, and for that, I am grateful. If you cannot relate to that, the same thing happened to me on the other side of my professional career, land development, some ten to twelve years ago. Learning Civil3D changed that. Many people are familiar with CAD, and a significant number are also familiar with GIS. It is the common ground and the intersection of these two that makes things go right. CivilGEO understands that. **What do you dislike about GeoSTORM?** Not a 2D solver yet, but that is coming, so not much. **What problems is GeoSTORM solving and how is that benefiting you?** Like I said, it is the common ground between GIS and CAD and the ability to switch seamlessly between the two. I don't know of anybody else paying myuch attention to that. While the reality is that most water resources dayly issues live at that scale that could be defined as the common ground between these two. **Official Response from Sara Presta:** > Hi David, Thank you for taking the time to share your review; your comments certainly made our day!

Large Learning Curve but Worth the Time **Rating:** 5.0/5.0 stars **Reviewed by:** Myron F. | Principal/Owner, Small-Business (50 or fewer emp.) **Reviewed Date:** September 05, 2025 **What do you like best about GeoSTORM?** Like most reviewers indicated, there is a learning curve to GeoStorm. However, there is an ease of use right out of the gate. It is well worth the time spent and CivilGeo's technical Support is very responsive and willing to help. We have implemeted Geostorm on 3 projects so far for land entitlement and the ability to easily change terrains or CAD files while projects are evolving. This allows us to insert Hydraulics and Water Quality earlier on in the conversations and more efficiently allocate areas for stormwater treatment and storage. The software was easily integrated into our projects and implementation throughout the company was fairly simple. **What do you dislike about GeoSTORM?** The biggest downside is getting the local agencies familiar with the outputs of GeoStorm. Locally there is 2 software platforms developed in the 1990s and bringing a new report format for approval took a little convincing. **What problems is GeoSTORM solving and how is that benefiting you?** We are able to talk about hydraulics and water quality earlier in the conversations when entitling property. Because GeoStorm is flexible and accepts DWGs and Digital Terrains, the model can develop alongside the other disciplines. **Official Response from Sara Presta:** > Hi Myron, Thank you for taking the time to share your review; your comments certainly made our day!

The GeoSTORM is a reliable, easy to use and can be used for any project. **Rating:** 5.0/5.0 stars **Reviewed by:** Sara I. | Civil 3D Designer, Small-Business (50 or fewer emp.) **Reviewed Date:** July 11, 2025 **What do you like best about GeoSTORM?** That automates many things and saves you valuable time. **What do you dislike about GeoSTORM?** This comment is more about the content than the program itself. And it is, that for now I don't have explanatory videos of many tools, for example how to configure each of the LID methods, how to configure a chamber or a pond, also how to connect these systems to download points to obtain the post development runoff and others things. But I understand that they are slowly integrating material and I know they will succeed. **What problems is GeoSTORM solving and how is that benefiting you?** First, the time, the program already calculates many things that in other programs you have to look for it manually and secondly that not only calculates but gives you the information in real time of the data that is using, for example, the types of soil. **Official Response from Sara Presta:** > Hello Sara, Thanks a lot for sharing your review.

GeoSTORM is challenging to learn, but extremely useful. **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Civil Engineering | Mid-Market (51-1000 emp.) **Reviewed Date:** June 20, 2025 **What do you like best about GeoSTORM?** 1. The program is very advanced and capable of performing some tasks better than Bentley's products, such as using terrain to generate drainage areas. 2. The ease of finding rainfall data and hydrologic soil groups is very useful. 3. Technical support was very helpful. **What do you dislike about GeoSTORM?** 1. I don't like that there is a steep learning curve. I had to call technical support to learn how to make just a simple drainage network layout. 2. The fact that catch basins have to be attached to a roadway segment is confusing and time-consuming. 3. I've experienced a lot of latency with the software. I updated to the latest version, but it didn't completely take away the issue. It seems like it's overwhelmed very easily once you add terrain. 4. I wish it integrated better with Civil3D like Bentley StormCAD, but it's not a dealbreaker. **What problems is GeoSTORM solving and how is that benefiting you?** Once we learn the program better, I expect it will speed up our calculations considerably for desiging storm sewers. **Official Response from Sara Presta:** > Hello, Thanks a lot for sharing your review.

Software that incorporates all stormwater requirements into one program **Rating:** 4.5/5.0 stars **Reviewed by:** Michelle L. | Principal Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** March 31, 2025 **What do you like best about GeoSTORM?** It's great to finally have a software that incorporates stormwater requirements for hydromodification and hydraulic analysis into one program. I can easily import my data from Civil 3D, including surfaces, flow paths, drainage areas and storm pipe information into GeoSTORM. I am able to choose what type of design storm I want to use, which storm frequencies I want to model, and customize the reports of the results. The best part about GeoSTORM is the 24-7 customer support. It is never easy to learn a new program, but the learning curve has been quick because I can call anytime and get a hold of someone who point me in the right direction. **What do you dislike about GeoSTORM?** It needs more options for customizing irregularly-shaped storage chambers. There needs to be a way to design outlet structures for bioretention areas. It would also be beneficial to have separate structures for manholes vs. drain inlets. **What problems is GeoSTORM solving and how is that benefiting you?** It is easy to transfer data between Civil 3D and GeoSTORM without entering the information twice. I can also select from different types of storm designs that I want to use. It also has a lot of the information already in the program, such as bing maps, FEMA flood boundaries and soil surveys. **Official Response from Sara Presta:** > Hello Michelle, Thanks a lot for sharing your review.

User Friendly Software That Improves Efficiency of Data Collection and Analysis **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Civil Engineering | Small-Business (50 or fewer emp.) **Reviewed Date:** March 28, 2025 **What do you like best about GeoSTORM?** Having experience with XPSWMM and other hydrologic and hydraulic software products, I am most impressed with GeoStorm's ability to quickly capture and place on your projects horizontal and vertical datum publicly available data such as Google maps, USGS surface files, FEMA flood zone data, USACE wetland data, as well as land use data, % impervious data, etc. Without setting foot in the field, an engineer can quickly develop watershed / subbasin drainage areas, estimate overland slopes, and other hydrologic features of a project area such as runoff coefficients and estimated times of concentration along an automatically computed (or manually drawn) hydraulic length. The software can also download NOAA Atlas 14 precipitation data for the project site at the click of a couple of buttons, from which hydrologic calculations utilizing the Rational Method and Modified Rational Method (among other modeling approaches) can be completed. Depending on the size and complexity of the project area, a fairly detailed hydrologic study can be completed within just a few hours. That, to me, is the biggest time saver. Hydraulically, setting up a drainage network is also very user friendly. GeoStorm has the ability to reference in your CAD files (in AutoCAD or Microstation formats) and to also place same into the appropriate datum to mesh with the layers discussed above. Tracing of your hydraulic network on your design is greatly simplified as a result. Then, assigning drainage areas and their hydrologic results to various points of your hydraulic network is also a great asset. Lastly, Customer Support is exceptional. Any question is answered in a very timely manner with the transmittal of an email to their support team (24/7). Most times, you receive a call within an hour from an expert, and I have yet to have a problem left unresolved or a question unanswered. GeoStorm designers have even updated the software twice upon my request to include certain features. I can't think of any other software company that provides that level of service.   All in all, I would recommend this software to civil engineers. The workflows within the software to create hydrologic and hydraulic models is very fluid and remarkably easy to navigate. **What do you dislike about GeoSTORM?** I am still trying to get comfortable with the hydraulic calculations that GeoStorm utilizes to analyze hydrologic and hydraulic networks. Until then, I have nothing negative to say at all about the software. **What problems is GeoSTORM solving and how is that benefiting you?** For us, GeoStorm has solved the workflow problem of providing one platform that can quickly capture publicly available background data, onto which hydrologic modeling can be set up, onto which a drainage network can be laid out, from which analyses can be completed. **Official Response from Sara Presta:** > Hi, Thank you for taking the time to share your review; your comments certainly made our day!

GeoSTORM Review **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Civil Engineering | Small-Business (50 or fewer emp.) **Reviewed Date:** May 19, 2025 **What do you like best about GeoSTORM?** GeoSTORM provides a relatively easy to use software that is accurate and detailed and great for any job. It has helped me analyze projects with confidence and assurance that it will leave me satisfied with my final results. **What do you dislike about GeoSTORM?** The only thing that I dislike is the regional stormwater data that is available. Most of the time it's due to the area itself, but sometimes the regional rainfall data tool is under maintenance which can delay a project. CivilGeo is very good at getting things repaired in a timely manner, so it has never been costly to a project I have worked on. **What problems is GeoSTORM solving and how is that benefiting you?** This is helpful with larger residential developments and how the stormwater system is integrated into our grading. **Official Response from Sara Presta:** > Hello, Thanks a lot for sharing your review.

Time saver. **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Civil Engineering | Small-Business (50 or fewer emp.) **Reviewed Date:** June 17, 2025 **What do you like best about GeoSTORM?** I like the CAD resemblance. The way you pan and the object snapping. The ease of generating terrains from a CAD surface, importing/exporting CAD pipe network, very convenient. Saves a lot of time during design. You no longer have to do things twice. Also, the available elevation/terrain data is very convenient. You don't need lidar data or a CAD surface to use the software. The report generation feature is a huge time saver and does a really good job displaying the results and just making it look good. **What do you dislike about GeoSTORM?** Stamp geometry feature crashes at times. **What problems is GeoSTORM solving and how is that benefiting you?** Helps save time during design phase. **Official Response from Sara Presta:** > Hello, Thanks a lot for sharing your review.
