o Transit Mix Concrete Co.
Response: A Noxious Weed Management Plan has been included in Exhibit E.
However,it should be noted that the state-listed noxious weed species mentioned
were not necessarily widespread but often occur in specific areas of the area; some
may occur only in lower elevation areas that are outside of the permit area.
EXHIBIT K-Climate(Rule 6.4.11)
General Conditions
183) Comment: The text states that the most distinguishing characteristic of the Colorado
Springs climate is the frequency and intensity of thunderstorms during summer.
According to weather records,this city is the most thunderstorm prone city west of the
Mississippi River. The text then states that during summer,thunderstorms that drop an
inch or two of rain in periods of under an hour are not uncommon. Given this
information,is the proposed stormwater management plan designed to function properly
during these frequent and intense rainfall events?
Response: The stormwater management plan is designed to safely convey runoff
from design storm events using storm depths calculated by NOAA. The storm
events and designs will be included in Exhibit G. This information will be included
in a revised permit submittal provided to CDRMS on or prior to July 22,2016.
184) Comment: The text describes another important climatological feature being the
monthly distribution pattern of moisture, especially during the growing season. However,
much of that moisture comes in quick and occasionally intense storms that exhibit heavy
runoff and only moderate soil absorption. Once again, is the proposed stormwater
management plan designed to accommodate these periods of heavy runoff?Additionally,
is the proposed revegetation plan suitable for reclamation under these particular
climatological conditions, including type of plant species?
Response: The stormwater management plan is designed to safely convey the
runoff from periods of heavy precipitation. The selected plant species are native to
the area and are therefore well adapted to the climate conditions.
Wind—Site Modifications
185) Comment: The text states that due to the potential for strong winds at the proposed site,
consideration should be given to using moisture conserving techniques where conifers
are to be planted. Please describe what moisture conserving techniques the applicant
intends to implement.
Response: All plants selected for reclamation are native species and are adapted to
the project climate. Also,vegetation has been established during reclamation at
Transit Mix's nearby operations without the need for supplemental water.
