At this meeting, we will have a presentation from Jeremy Hamer and Kim Pirri on elevation certificates. They gave this presentation at the CASFM conference, but not everyone was able to attend. Here is the description from the CASFM program: “Does your community participate in the CRS? Are your Elevation Certificates correct? Join us to review all the nit-picky details of the Elevation Certificate, common errors, and what you, as a community, can do to correct those pesky errors.” Thanks to Jeremy and Kim for volunteering to do this! I think communities will find this topic helpful in preparation for the annual recertification due in May.

NeFSMA Kingsley Dam Tour and 2019 Western Nebraska Seminar
2019-05-02 12:00 - 2019-05-03 13:00 | Kingsley Dam/Quality Inn & Conference Center
https://www.casfm.org/wp-content/uploads/2019/03/2019-NeFMSA-Western-NE-Seminar-Agenda.pdf

On May 2-3 NeFSMA will having a tour of Kingsley Dam, followed by speakers regarding issues related to the dam, dam safety, endangered species, the Platte River Basin, and more.
The NeFSMA professional development committee members are very excited about this event since you don’t normally get to tour a dam of this magnitude as part of a floodplain/stormwater organization. The event has been set up so public officials in eastern NE can travel during the morning of a work day, justify an overnight stay since we will have an evening program with CEC’s, and travel home the afternoon of a 2nd day. But it turns out Denver is actually closer to Ogallala than Lincoln (3 hours verses 4 hours) so works great for Colorado CASFM members to make the trip also!
We have been pre-approved for 7.5 CEC’s from ASFPM so is a great opportunity also for CFM’s to pick up quite a few hours if they can’t make one of your schedule events with CEC’s. We can’t offer mountain views like you do at your annual convention (was at your Crested Butte conference in 2016 so know a little bit about your conference amenities), but can offer a big lake, great tour and some floodplain/stormwater socializing. We also attempted to have some less regional (Nebraska) presentations the next day so does not sound like an all Big Red event.

You will receive 12 ASFPM Core CEC’s toward CFM certification.
What Will You Learn?
Stormwater detention has been identified to be very effective means to mitigate the effects on stormwater runoff and flooding due to urbanization of watersheds. It is a very important part of urban stormwater systems and is critical in protection to public provided beyond those offered by BMP and LID facilities. In this course you will learn:
1) Assessment of urbanization impact on increase
of runoff rates and volumes
2) Types of stormwater detention,
3) Hydrograph method for estimating detention volume
for large watersheds
4) FAA method for estimating detention volume for
small watersheds
5) Empirical methods for Excess Urban Runoff Volume (EURV),
Water Quality Capture Volume (WQCV) and 10-yr and 100-yr
detention volumes
6) Detention basin’s pre-sizing for multiple flood events
7) Detention basin’s pre-shaping to produce
the stage-storage curve
8) Design of inflow system using a forebay and inflow
channel for in-stream basin
9) Design of inflow system using a culvert-diversion
structure for off-stream basin
10) Design of outflow structure with WQCV plate,
low-flow orifice, and high-flow grate,
11) Design of outfall culvert using restricted plate to
produce the stage-outflow curve
12) Design of basins operated by HGL using equalizer
pipes and flood gates
13) Reservoir routing method to evaluate basin’s
performance
14) Design of micropool in front of the WQCV plate
15) Design of Full Spectrum Detention (FSD)
16) Application and impact of watershed-wide regional FSD
17) Design-storm modeling versus continuous simulation
of detention basins
18) Effect of location in watershed on detention
basin effectiveness
19) Maintenance of detention basins and
various design components
20) Design and Review examples using
UDFCD’s UD-Detention workbook tool
This Course Will Cover:
The lectures and work sessions are designed to teach how to design a stormwater detention system. You will be provided with a easy to use, spreadsheet based computer model Stormwater Detention Design that was specifically developed for you to:
1) Calculate the required storm water detention volumes,
including ones for Water Quality Capture Volume,
Excess Urban Runoff Volume, 10-yr and 100-yr storms
2) Estimate the basin geometry using triangular, rectangular,
or elliptical shapes,
3) Develop the final stage-storage-outflow relationships, and
4) Conduct reservoir routing through the basin under design.
Detentions and BMP outlet structures can be very complicated and can contain of multiple orifices, weirs, perforated plates, and culverts.
Much of the class will be in workshop mode, in which you will experience hands-on operations and how to achieve various stormwater and flood mitigation using detention design techniques. Stormwater Detention Design Software’s design procedures used fully comply with proven hydraulic design protocols applicable in all areas of United States and the rest of the world. You will also learn how to use spreadsheet-based freeware developed by the Urban Drainage and Flood Control District to size detention volumes and outlets.
Bring Your Own Computer.
You will need it to run the Excel workbooks provided to you in the class.

Colorado is a great place to visit!
April is a beautiful time to visit Colorado. If you’re looking for a mixture of mountains and relaxation, check out the Strawberry Park Hot Springs in Steamboat or the Hot Springs in Glenwood Springs. Feel like enjoying the outdoors but don’t want to travel all the way to the mountains? Visit Roxborough State Park and enjoy a light hike on Willow Creek Trail where you can take in the wildflowers and practice your bird watching skills. If you would rather stay close to or in the city of Denver, Larimer Square has several fun boutiques for you (and even your pets)! When you’re ready for a break, there are a variety of delicious cafés and restaurants to choose from! So, if you come and attend this class, you may want to extend your stay (or even come early) and take advantage of the most attractive area of the United States.
