Emergency Flood Evacuation Plan For InRoads LLC
Site Location and E911 Address: 3034 560th Ave. Ames, IA 50010 GPS Coordinates 41°59'47.2"N 93°34'47.0"W
The evacuation procedures should include options for the evacuation of ALL people on site and ALL Portable Asphalt Plant and related equipment. Everything on site is related so the Primary plan will be to evacuate everything and everyone from the site with the exception of stockpiled materials. It should be assumed that visitors will not have local knowledge and will need to be guided to a safe route / location.
Situation and Considerations: The 5-6 acre site will have between 2 – 20 people on it at any given time. Equipment needs to be taken from the floodplain area and relocated in case of a flood.
Shelter & Welfare If an evacuation is necessary, the equipment and people will be evacuated to 1409 NW Laurel St., Elkhart, Iowa.
Document Control The Plan should be owned, maintained, and updated. All users should be reminded periodically to provide details of any changes that may materially affect the plan in any way. Details of changes should be recorded and the documentation updated. This should be completed either through a re-issue of the plan or via an amendments record. Documentation control procedures should be in place to ensure that only the current version of the plan is in circulation. The Plan will be in the hands of InRoads during construction. Jeff Steinkamp, Project Manager, Cell: 515-499-0077, Email: [email protected] will update the plan as material changes occur. Distribution of the updated plan will be provided to Leanne Harter, County Outreach and Special Projects Manager at Story County. Her telephone number is 515-382-7247 and email [email protected] as well as all below mentioned emergency response offices.
Key Points from Flood Risk Assessment The Site lies within the Floodplain that means there is a risk of flooding. The site is located near the South Skunk River which is a rapid reaction water course and has caused significant flooding in the past. Based on historic data, the gauge reading at the confluence of the Squaw Creek and South Skunk river can rise as much as 8ft in a 24 hour period based on rain events in August 2010 or it can rise a record level 11ft in 24 hours based on data derived from May 29 – May 30, 2008.
A site specific flood risk assessment has been carried out on behalf of Joe Manatt which shows the flooding risk to currently be medium/high based on prior flood events and the fact that the site is located in a FEMA floodplain. The scale of site specific flood risk assessments vary widely in scope and this site assessment was on the low end of formality; the site can have water on it based on previous observations. The location of the plant will be graded and raised 18” above base flood elevation thus further reducing the chance of flooding on the forty-acre parcel where the wash plant is situated.
Authority Jeff Steinkamp with InRoads LLC will ultimately oversee monitoring and making the decision to evacuate the site. He will coordinate emptying fuel tanks, schedule InRoads employees to assist in moving the plant equipment and trucks to the designated Shelter & Welfare location, and contact emergency personnel, as needed.
Prevention The Site is developed to raise the plant level as mitigation against flood. No further preventative measures have been possible because nature of the watercourse.
Protection No Flood barriers have been installed to allow extra time for evacuation in the flood scenario. All equipment and personnel will be removed from site before water levels are a threat to the site.
Evacuation Route The attached map provides an evacuation route to 1409 Laurel St., Elkhart, Iowa. All equipment will be removed before flooding becomes a threat to the roads on the route.
Site Plan Layout A site plan proposed layout of the site is included in this submittal.
Preparation We will not perform a flood evacuation drill. Each piece of equipment is portable in nature.

Site Reoccupation: Once water levels recede to under 19.0ft and dissipating, it should be okay to reoccupy the site and continue operation of the sand manufacturing facility as planned. If the site is re- occupied following a flood event, the plan is to do so in the same manner in which the site was occupied prior to the flood. Some grading may need to take place, some rock placement may need to occur and some silt fence may need re-installed. InRoads will work with Story County Emergency Management, Floodplain Management, and Planning and Development to determine when the site can be reoccupied and if local permit requirements are met. InRoads will work with other state or federal agencies to determine if permit requirements are met prior to reoccupation.
Flood Warnings Following the Natural Hydrologic Forecast Website (https://water.weather.gov/ahps2/index.php?wfo=DMX) to monitor all river levels in Iowa and predicted forecast crest levels, specifically for this site gauge # Location: South Skunk River below Squaw Creek near Ames, IA, at the confluence of the South Skunk and Squaw Creek, (https://water.weather.gov/ahps2/hydrograph.php?wfo=dmx&gage=aesi4), action stage/on alert is 19.0ft, flood evacuation stage is 21.5ft, moderate flood stage is 23.5ft, and major flood stage is 24.5ft. The gauge will be monitored by Jeff Steinkamp of InRoads once per day at a minimum, but more often if rain is expected in the forecast. At this site in particular, the water levels can rise quickly during large rain events so predicted forecast crest levels are the best indicators of flooding probability. However, forecasted levels can be inaccurate, both on the high side and the low side of actual water levels. Once the predicted forecast crest levels reach 19.0ft, the site needs monitored on an hourly basis with the following action plans for each predicted forecast crest level:
If predicted forecast crest levels reach 19.0ft to 21.5ft, InRoads will call all suppliers to put them on alert of possible emergency evacuation. InRoads will maintain tank levels at a minimum if running the wash plant, so evacuation can occur quickly if conditions worsen.
If predicted forecast crest levels reach 21.5ft – 23.5ft, InRoads will unplug all cables and prepare each piece of equipment for evacuation. Sand production will cease, and tanks will be emptied until river levels begin to recede. Simple pieces of equipment should be moved to the designated Shelter & Welfare location outlined in this plan and should not occupy the site again until the predicted forecast crest levels are receding below 21.5ft. InRoads will have employees on call or already on site to help move the plant during this stage. Once actual river level readings reach 21.5ft (flood stage) as monitored each hour, InRoads will move pieces of equipment off site to the Shelter & Welfare location.
If predicted forecast crest levels reach 23.5ft and above InRoads will evacuate all pieces of equipment and take everything on site to the Shelter & Welfare location. We know from firsthand experience that water is on site when the gauge reads 22.84ft, as experienced most recently 12/15/2015. The likelihood of water on site with a predicted forecast crest level of 23.5ft and above is highly likely and evacuation should take place regardless of actual river level readings.
The following table will be kept up to date using key indicators from the above referenced website river monitor.
