1.0 GENERAL LOCATION AND DESCRIPTION

The following report provides detailed drainage information for existing and proposed conditions

of the McCune Ranch Subdivision project. The intent of this report is to show the routing of storm

water through the proposed site to provide map revisions of the FEMA defined floodplain. For

the drainage study, a minor flow is defined as the 5-year frequency storm and a major flow as

the 100-year frequency storm, however additional storms were also modeled per FEMA

requirements. The information given in this report is intended to provide an adequately detailed

analysis of on-site drainage areas and receiving facilities. This development is in a rural area

consisting of large-lot single family residential parcels, a small commercial area, preserved open

space, as well as the roads and required infrastructure.

GENERAL LOCATION

The site is located at 17480 Meridian Road North or, more generally, at the northwest corner of

Hodgen Road and Meridian Road North in unincorporated El Paso County, latitude 39°04’38” N

and longitude 104°36’47” W. The subject property is undeveloped and situated in the West Half

of Section 19, Township 11 South, Range 64 West of the 6th P.M., County of El Paso, State of

Colorado.

The site is bounded to the south by Hodgen Road, to the east by Meridian Road North, and to

the north and west by several parcels zoned primarily as Agricultural and Residential use with

some Forest Land. On the east side of Median Road is Forest Green Subdivision, a low-density

single-family development. On the south side of Hodgen Road is Bison Meadows Subdivision

which is also a low-density single family residential subdivision. The remainder of properties

surrounding the site have not yet been formally platted. The site has not been included in any

previous drainage study. West Kiowa Creek flows approximately through the center of the

property from the southwest corner to the northeast corner, just upstream, to the west of the

FEMA CLOMR Report


property lies the West Kiowa Creek Watershed 1-N-10 Reservoir. There are no irrigation ditches

on the property.

DESCRIPTION OF PROPERTY

The existing site contains 766 acres of agricultural grazing land and dry farm land. Ground cover

consists mainly of native grasses and shrubs and contains several stands of evergreen trees along

its southern and northern boundary. Existing wetlands are present along West Kiowa Creek and

its tributaries, wetland boundaries are located roughly 50 feet to either side of the thalweg of

West Kiowa Creek and the drainageway way to the south of the creek on the property. There are

no existing irrigation canals or ditches on the project site nor are there any major geologic

features. The property generally slopes in a northeasterly direction with slopes ranging between

1-16%. Soils consist of Alamosa loam, Brussett loam, Cruckton sandy loam, Elbeth sandy loam,

Holderness loam, Kettle gravelly loamy sands, Peyton sandy loam, Peyton-Pring complex, Pring

course sandy loam, Tomah-Crowford loamy sands and Tomah-Crowfoot complex. The majority

of the site has soils classified in Hydrologic Soil Group B; however, the property also contains a

mixture of soils from Hydrologic Soils Groups C and D located in the areas in and adjacent to West

Kiowa Creek and its tributaries.

The development of this property will consist of 143 2.5 to 5 acre single family residential lots

and the requisite public roads and stormwater infrastructure to serve them. Anticipated

construction activities include earthwork and paving associated with the public roads, as well as

the installation of culverts and water quality ponds to convey and treat stormwater on the site.

As previously discussed, West Kiowa Creek bisects the property, flowing from southwest to

northeast. In addition a major tributary of West Kiowa Creek flows north from a point halfway

along the southern property boundary and intersects West Kiowa Creek in the middle of the

property. The primary access for the site will be from Hodgen Road and Meridian Road. There

are no utility corridors located on the property at the current time.

2.0 DRAINAGE BASINS AND SUB-BASINS

MAJOR BASIN DESCRIPTION

The site resides within the West Kiowa Creek Watershed which is located near the northern

boundary of El Paso County, approximately 14.5 miles east of downtown Monument, CO. This

Watershed begins approximately 5 miles southwest of the McCune property and continues

another 10 miles to the northeast where it outfalls into Kiowa Creek which eventually discharges

into the South Platte River near Fort Morgan, CO.

DRAINAGE STUDIES, OUTFALL SYSTEMS PLANS, & SITE CONSTRAINTS

There are no major drainage studies for this area on record and no base flood elevations for this

reach of West Kiowa Creek have been established. In conjunction with the development of this

site, a floodplain study will be performed on the section of West Kiowa Creek located within the

property and a Letter of Map Revision will be submitted to FEMA to establish the floodplain

boundary on-site. The site is shown on FEMA flood maps 08041C0325F and 08041C0350F which

indicate that the majority site is in Zone X – area outside of the 0.2% annual chance of flood (see

the accompanying exhibits in the Appendix). The areas immediately adjacent to West Kiowa

Creek are designated as Zone A, which is a 100-year Flood Hazard Area in which no base flood

elevations have been determined There are no known irrigation facilities located on the property

at the current time.

PROPOSED CONDITION

In the proposed condition, stormwater runoff will continue to flow from southwest to northeast

as it does in the existing condition. The path of the main thalweg is not altered, however 2 new

box culverts are proposed at road crossings within the development. All existing drainage

patterns will be maintained throughout the site to the extent possible.

Source of Map: Natural Resources Conservation ServiceWeb Soil Survey URL: Coordinate System: Web Mercator (EPSG:3857)

Maps from the Web Soil Survey are based on the Web Mercator projection, which preserves direction and shape but distorts distance and area. A projection that preserves area, such as the Albers equal-area conic projection, should be used if more accurate calculations of distance or area are required.

This product is generated from the USDA-NRCS certified data as of the version date(s) listed below.

Soil Survey Area: El Paso County Area, ColoradoSurvey Area Data: Version 15, Oct 10, 2017

Soil map units are labeled (as space allows) for map scales 1:50,000 or larger.

Date(s) aerial images were photographed: May 22, 2016—Mar 9, 2017

The orthophoto or other base map on which the soil lines were compiled and digitized probably differs from the background imagery displayed on these maps. As a result, some minor shifting of map unit boundaries may be evident.

Description

Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms.

The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows:

Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission.

Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission.

If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.
