1. Site Description Additional information for permitted projects. For information only to fulfill the CDPS-SCP (Colorado Discharge Permit - Stormwater Construction Permit)

A. Project Site Description: The project includes the construction of Ramp Band the access road connection for the US 160 Interchange in Grandview. The project includes both uphill and downhill retaining walls, ramp and access road grading paving, and guardrail installation. Excavated material for Ramp B will be hauled for placement of the round-about embankment on the north s ide of US 160.

B. Proposed Sequencing For Major Activities : Excavation and grading of Ramp Band access road connection, hauling and placement of embankment material, mechanical reinforcement of soil, ground nail drilling and install, installation of precast panel facing, construction of concrete wal l with rebar.

c.

D.

Acres Of Disturbance : Total area of construct ion site: 53.8 acres Total area of disturbance: 6.3 acres Acreage of seeding: 5.0 acres

Existing Soi l Data: The US 160 Ramp B soi l s consist of three main soil types 1nclud1ng the Zyme Clay Loam 3 to 25% s lopes , the Zyme-Rock outcrop complex 12 to 65% s lopes and the Arboles Clay 3-12 percent slopes .

Zyme Clay Loa~ 3 to.25% slopes - This shallow well drained soil is on ridges and hills. It 1s formed 1n_res1du~m d~rived from.shale. Average annual precipitation is 14 to 18 inches. The soil profile ,n general ,s composed of 4 inches of grayish brown clay l oam. The under lying material is grayish brown clay loam over soft sha l e at a dept h of 10 inches. _Bedrock depth ranges from 6 to 20 inches . Permeability is slow, runoff i s rapid and erosion h~zard is high . Rangeland vegetation is mainly Indian ricegrass, western wheatgrass, Big sage, Gamble oak, RM Juniper, Pinyan pine, and bitterbrush .

Zyme-R9ck outcrop complex 12 to 65% - This map unit is on ridges and hills. It is formed 1n residual material derived from shale. Average annual precipitation is 14 to 18 inches. The soil profile in general is composed of 4 inches of grayish brown clay loam. The underlying material ,s grayish brown clay loam over soft sha l e at a depth of 10 inches. Bedrock depth ranges from 6 to 20 1nches. Runoff i s rapid and erosion hazard is high. Rangel~nd vegetat1on.1s ma1nly_Ind1an r1cegrass, western wheatgrass, Big sage, Gamble oak, RM Juniper, Pinyan pine, and b1tterbrush.

Arboles Clay 3 to 12% s lopes - This deep well drained soil is on side slopes and in upland vall~y~. It 1~ formed in fine textured a11uvium.der1ved from shale. Average annual prec1p1tat1on ,s 14 to 18 inches. The soil profile ,n general is composed of 6 inches of brown clay, subsoil is also brown clay to 24 inches. Permeability is slow, runoff is medium and erosion hazard is moderate. When dry the soil has deep cracks that extend to the surface. _Rangeland vegetation is mainly Indian ricegrass, junegrass, western wheatgrass, Big sage, Gamble oak, RM Juniper, Pinyan pine, and bitterbrush .

E. Existing Vegetat ion, Including Percent Cover: The Project Area is located within the Pinyan pine/Rocky Mountain juniper woodland community. Much of the native vegetat i on and surrounding hillside has been previously disturbed during the Grandview 4~ Lane project.
