WETLAND DELINEATION: AUTHORIZED AGENT Montane Environmental Solutions, Ltd. Post Office Box 281 Silverthorne, Colorado 80498 (970)468 -0450 " 0 I. PURPOSE AND NEED AND PROJECT DESCRIPTION �• The Applicant hired a landscape contractor to daylight a stormwater culvert that ran along the east boundary of 232 West Meadow Drive. He wanted the exposed water routed into a water feature lined with an impermeable layer and river rock. The lower section of the water feature is within jurisdictional wetlands and includes a small aesthetic pool. Approximately 7 cubic yards of medium sized (6.12 -inch) river rock was used (see PHOTOGRAPHS 1 &2 of wetland delineation report). The contractor removed wetland vegetation from approximately 1,459 square feet ' (calculation does not include removed upland vegetation) and installed 224 square feet of water feature within the cleared wetland area. ' The water feature is intended for aesthetic purposes only. The Applicant wanted to utilize the stormwater runoff contained in the buried culvert as an amenity to his landscape design. Lapin, 232 West Meadow Drive, Vail, Colorado, March 11, 2003 P. 1 �.+ `✓ C II. DESCRIPTION OF WETLANDS DISTURBED A delineation of wetlands was conducted by Montane on October 7, 2002 using the 1987 Corns Manual for Wetland Delineation Methods for "Atypical Situations" were used due to the recent ., clearing of vegetation and lack of historic photographs. The full delineation report is attached to this notification. There is one wetland area identified on the property, but again its boundary was approximated due to the after - the -fact nature of the delineation. It may be classified as slope and low -order riverine wetland, associated with the alluvial aquifer of Gore Creek and groundwater daylighting on the banks of Gore Creek. Wetlands removed, based on what is seen in those remaining, were likely willow dominated shrub wetlands alongside Gore Creek. Past disturbance is evident from the proliferation of weedy, invasive plants such as Canadian thistle. Native species within the wetlands include Salix monticola, S. planifolia, S. drummondiana, Distigea involucrata, and Agrostis stolonifera. III. DESCRIPTION OF DISTURBANCE The contractor removed wetland and upland vegetation during development of the water feature. The area of removed wetland vegetation is 1,459 square feet, The soil has also been compacted due to heavy equipment and trampling by workers (see PHOTOGRAPHS in wetland delineation report). It appears that only vegetation clearing has occurred with the ordinary high water (OHW) level. The water feature is located outside of the 100 -year floodplain and is therefore also likely outside of the OHW plane as well. The water feature permanently affects 224 square feet of jurisdictional wetland and (FIGURE 2). It is likely the impermeable fabric in the drainage will prohibit any groundwater recharge to adjacent wetlands however the wetlands on the property persisted when the water was contained in a culvert. Therefore it is not likely any indirect impacts will occur by its permanence. Water re- directed from the culvert will enter the water feature and discharge into Gore Creek. The ' location of the discharge will remain the same, in addition, quantity of discharge into Gore Creek will remain nearly the same with minimal evaporate loss, as shown in the table below. 1 Lapin, 232 West Meadow Drive, Vail, Colorado, March 11, 2003 p. 2 • National Oceanic and Atmos pheric Administration, , National Weather Service Technical Report 33 • *Western Regional Climate Center, 3/2003 website. IV. MINIMIZATION OF WETLAND IMPACTS The Applicant will restore the cleared wetland vegetation around the water feature, with native wetland and mesic material in spring, 2003. Appropriate siltation control will be installed and maintained during planting so to minimize runoff into Gore Creek. A suitable erosion control fabric will be installed and maintained after seeding until vegetation is established. Plants from the following list of wetland species will be planted to meet both the Applicant's needs and the native wetland community. These plants are all available locally in the nursery industry. Willows will be planted alongside Gore Creek and within the OHW to stabilize the bank and prevent erosion. ESTIMATED MONTHLY EVAPORATIVE LOSSES FROM WATER.

POST OFFICE BOX 281 SILVERTHORNE, COLORADO 8049 (970) 468 -0450 WETLAND DELINEATION REPORT LAPIN RESIDENCE ' 232 WEST MEADOW DRIVE, VAIL COLORADO I. INTRODUCTION Montane Environmental Solutions, Ltd. (Montane) was retained by Mr. Mery Lapin (Client) to identify jurisdictional wetlands that occur on his property located at 232 West Meadow Drive in Vail, Colorado, Eagle County. It is also known as a Part of Lot 7, Vail Village Filing No. 2, located at approximately 39° 38' 34" North, 106° 22' 51" West and the NE 1 /4 NE 1 /4 NE 1 /4 of Section 7, Township 5 South, Range 80 West (FIGURE 1). It is accessed from Interstate 70 to Exit 176 (Main Vail) south under 1.70 to Vail Road; from Vail Road, west onto West Meadow Drive. The property is immediately across from the Vail Valley Medical Center on the south side of West Meadow Drive, house number 232. The delineation was conducted on October 7, 2002 and is part of an after - the -fact permit application for a Nationwide Permit Number 18 - Minor Discharges. The wetland delineation is an approximation of the former jurisdictional boundary prior to residential hardscaping where water that was once enclosed in an underground culvert has been opened up into a water feature through the property. Part of the water feature, which is lined with PVC liner and river cobble ( - 5 -12 inch diameter cobble), is located within jurisdictional wetlands (PHOTOGRAPH 1). In addition, during construction, vegetation was removed entirely for construction access and installation (PHOTOGRAPH 2). According to the Client, no historic photographs are available, however the jurisdictional wetland boundary was approximated based upon remnant native vegetation, adjacent vegetation, remnant and native soil horizons, and indicators of ordinary high water of Gore Creek. II. VICINITY AND GENERAL SITE DESCRIPTION The property is located in Vail Village at approximately 8,120 46ot elevation within the Gore Creek valley, which is also occupied by Interstate 70. It is situated in a residential neighborhood and commercial area where significant development has occurred and little remains in native condition. The natural ecosystem of the valley slopes at this elevation is lodgepole, spruce -fir, and aspen forests. West Meadow Drive is on the south side of Interstate 70 and runs east /west paralleling Gore Creek, separated by approximately 1 /2 acre single - family residences. Spruce trees dominate the riparian canopy of Gore Creek in this reach, and willows with twinberry, and occasional bog birch dominate the shrub layer. The property is a sloping parcel, which is part of the former active floodplain of Gore Creek. The slope is approximately 17% from the main house to the active channel. It is upon this slope where part of the water feature has been located and vegetation has been removed (PHOTOGRAPH 3). The upland areas have been landscaped however a few large native spruce trees remain around the Wetland Delineation 232 West Meadow Drive, Vail Colorado P. 1 house. III. WETLAND DESCRIPTION The wetlands that occur on the property are located on the banks of Gore Creek. They are associated with the alluvial aquifer of Gore Creek and groundwater that appears to daylight on the lower elevations of the property near the creek. They may be classified as slope and low -order riverine wetlands. The remnant wetland areas that occur on the property are low quality in that they have been significantly invaded by thistle Cirsium arvense (PHOTOGRAPH 4). The Town of Vail had a culvert along the east property line that conveyed stormwater and surface water from upgradient drainages to Gore Creek. The Client wanted to daylight the water and create a water feature on his property. During construction, the contractor removed all necessary vegetation to accomplish the project, including some jurisdictional wetland vegetation. The cleared area likely resembled that of the remnant wetlands located east and west of the property. As stated previously, there are no historic photographs available, according to the Client. The dominant wetland vegetation is mountain willow (Salix monticola) with occasional twinberry honeysuckle (Distigea involucrata). The understory is primarily C. arvense. A. HYDROLOGY Both groundwater daylighting on the Gore Creek slopes and the alluvial aquifer support the wetlands located on the property. At the time of the survey which was late in the year and during a drought year, the soil was not saturated, but moist. B. SOILS There is no soil survey coverage for the Vail Village area by the Natural Resources Conservation Service (NRCS). However it is possible that the soil identified is the Forsey cobbly loam 3 to 12 percent slope because that is the soil series that is shown immediately downstream in the NRCS soil survey. The Forsey series is a loamy - skeletal, Argic Cryoboroll, this is a like a typic Cryoboroll (a Mollisol) with an argillic horizon. The soil identified on the site appeared to me a mixture of native soil (Sample Point 2) and ' imported topsoil (Sample Point 1). At Sample Point 1 the horizons appeared to be combined due to the recent disturbance and no mottles were present (PHOTOGRAPH 5). However in Sample Point 2, which was located near the protection of a spruce tree, the ' horizons remained intact with the B and C horizons exhibiting mottling PHOTOGRAPH 6). ' G VEGETATION The remnant wetlands adjacent to Gore Creek are mesic riverine wetlands dominated by Wetland Delineation 232 West Meadow Drive, Vail Colorado p. 2 dense willow growth with occasional twinberry honeysuckle (Distigea involucrata) and patches of thistle ( Cirsium arvense). Evidence of more extensive graminoid vegetation remains, but late in the season there had been considerable die -back. It is likely that the cleared wetland vegetation was similar to this existing vegetation. The riverine wetlands were probably much wetter historically, however development along the creek has interrupted any groundwater supplementation. The table below lists the common plant species identified on site.

METHODS USED ' The wetland delineation methods used were in accordance with the U.S. Army Corps of Engineers Wetlands Delineation Manual January 1987. An on -site inspection for an "Atypical Area" was performed. The data for the sampling points included vegetation and hydrology indicators. Soil pits were dug to a depth of 16- inches and were used to identify the presence of reduced soil conditions; depth to saturated soil, and depth to free water. Where indicators had been altered, interviews with contractors, and the landowner were conducted. In addition, inferences were made from adjacent native vegetation, soils, and hydrology. Wetland boundaries were determined by the percentage cover of hydrophytic plant species (obligate, facultative wet, and facultative), indicators of wetland hydrology, the presence of hydric soils, and topography.
