HomeMy WebLinkAboutFIRST COMMUNITY BANK PLAZA - PDP - 49-05 - SUBMITTAL DOCUMENTS - ROUND 1 - SUPPLEMENTAL INFORMATIONA pedestrian bridge is being proposed to allow pedestrians to cross the canal for more direct access to adjacent land uses and also to encourage their enjoyment of the canal and the birds that we hope will continue to be attracted to the area. insect diversity as identified in the NAPP; remnant native prairie habitat; mixed foothill shrubland; foothill ponderosa pine forest; plains cottonwood riparian woodlands; and any wetland greater than one -quarter ('/4) acre in size. As the natural area characterization study indicates, there are no raptor habitat features, nests or roost sites in this area. The one species of special interest currently utilizing the area is the aforementioned red fox. It has been suggested by the Division of Wildlife the use of the area by the fox should not be encouraged because of danger to fox and human beings given the high pedestrian and traffic volumes in the area. While it is not the intention if is net deshwb to encourage continued use by the fox, accommodations have been made to preserve the existing den location and iris tne�to encourage and enhance the continued use of the area by watelfe l a*d-songbirds. Where possible, native shrubs will be placed in the buffer zone along the canal, however, we are somewhat limited because we need to allow for truck access in order to maintain the ditch. Where we can, on the reminder of the project site, we have tried to plant native species and utilize trees, shrubs and ground covers in unique ways to provide structurally diverse habitat for songbirds. (e) The project shall be designed so that the character of the proposed development in terms of use, density, traffic generation, quality of runoff water, noise, lighting and similar potential development impacts shall minimize the degradation of the ecological character or wildlife use of the affected natural habitats or features. It is our intent to create wet ponds in two storm water detention areas to provide wetland habitat previously non-existent on the site. Not only does this approach utilize best management practice to insure clean storm water runoff but it provides valuable wildlife habitat as well. (f) The project shall be designed to integrate with and otherwise preserve existing site topography, including but not limited to such characteristics as steepness of slopes, existing drainage features, rock outcroppings, river and stream terraces, valley walls, ridgelines and scenic topographic features. No retaining walls are used along the canal. The site has been graded so that the existing ditch bank can be preserved along with a 15-20 foot wide buffer. (g) The project shall be designed to enhance the natural ecological characteristics of the site. If existing landscaping within the buffer zone is determined by the decision maker to be incompatible with the purposes of the buffer zone, then the applicant shall undertake restoration and mitigation measures such as regrading and/or the replanting of native vegetation. The buffer zone adjacent to the ditch bank will be re -seeded with native grasses and shrubs to replace the non-native and weedy species that currently exist. (h) The project may be designed to provide appropriate human access to natural habitats and features and their associated buffer zones in order to serve recreation purposes, provided that such access is compatible with the ecological character or wildlife use of the natural habitat or feature. The proposed parking lot encroaches into the LUC's suggested 50-foot buffer zone around the existing den and along the canal. Given that both the City and the Division of Wildlife agree that this site is not the best place to encourage habitation by the fox, the applicant is requesting that the encroachment be allowed. However, since the direction provide by both in City Plan and the Fort Collins Land Use Code shows that the community values natural habitats such as fox dens and wildlife movement corridors it is our intent to preserve the current location of the fox den through limiting disturbance during construction, providing additional screen and by qualitatively replace these disturbances by enhancing_e�e-the continued use of the site by wa and songbirds. The following outlines how we intend to do this: (a) The project shall be designed to preserve or enhance the ecological character or function and wildlife use of the natural habitat or feature and to minimize or adequately mitigate the foreseeable impacts of development. The project is designed to provide an average buffer distance along the canal of approximately 20 feet. This zone will be stripped and re -vegetated with native grass and shrub species while maintaining reasonable access for maintenance of the canal. (b) The project, including, by way of example and not by way of limitation, its fencing, pedestrianibicycle paths and roadways, shall be designed to preserve or enhance the existence of wildlife movement corridors between natural features, both within and adjacent to the site. Given the project's urban nature and the desirability to create an opportunity for pedestrians to cross the canal via a pedestrian bridge, e�nhanee these bridges are typical of bridges already located along the canal and have been found not to limit the use of the canal as a movement corridor for small animal species such as the fox mentioned in the introduction. However, native shrubs will be located along the canal where possible to provide more structural diversity and food sources for songbirds that utilize the area along the canal. (c) The project shall be designed to preserve significant existing trees and other significant existing vegetation on the site. The ditch company has tenseveremoved existing trees along the canal in recent months. In addition there are six Colorado Blue Spruce trees on the site that are impacted by the project. Two of the trees will be relocated on the site and four will be mitigated. See landscape plan. (d) The project shall be designed to protect from adverse impact species utilizing special habitat features such as key raptor habitat features, including nest sites, night roosts and key feeding areas as identified by the Colorado Division of Wildlife or in the Fort Collins Natural Areas Policy Plan (NAPP); key production areas, wintering areas and migratory feeding areas for waterfowl; key use areas for wading birds and shorebirds; key use areas for migrant songbirds; key nesting areas for grassland birds; fox and coyote dens; mule deer winter concentration areas as identified by the Colorado Division of Wildlife or NAPP; prairie dog colonies over fifty (50) acres in size as included on the Natural Habitats and Features Inventory Map; key areas for rare, migrant or resident butterflies as identified in the NAPP; areas of high terrestrial or aquatic \.. RipleyAB IATEHINC _::Indscape Architecture Urban Design Planning November 23, 2005 Response to Buffer Zone Performance Standards The following is intended to address the City's Buffer Zone Performance Standards found in Section 3.4.1 Natural Habitats and Features, (E) Establishment of Buffer Zones. The standards are provided in bold for easy reference. (1) Buffer Zone Performance Standards. The decision maker shall determine the buffer zones for each natural habitat or feature contained in the project site. The buffer zones may be multiple and noncontiguous. The general buffer zone distance is established according to the buffer zone table below, but the decision maker shall reduce or enlarge any portion of the general buffer zone distance, if necessary in order to ensure that the performance standards set forth below are achieved. The applicant recognizes that the project site has some unique environmental qualities. Mike Phelan, a wildlife biologist, with Cedar Creek Associates has been retained to prepare a natural areas characterization study. This paper is in response to the information and recommendations contained in that study. The study states that the project site is vegetated entirely by non-native grasses and weedy species. The only habitat feature of value to wildlife is the Larimer County Canal No. 2, which runs along the west and south edge of the project site. Urban adapted waterfowl such as Mallards and Canadian geese use the ditch when it has water. Mice, voles and pocket gophers are the only species likely to establish resident populations. In addition a variety of songbirds occasionally use the area. Last, but not least, a red fox does use the property. The existing fox den is shown on the site plan. Foxes have successfully reared young in the den in the past. The den is currently not in use because it is not breeding season for the fox. The natural areas issues important for this project site are: 1) An existing fox den (LUC recommends 50-foot buffer) 2) The canal's use as a wildlife movement corridor for the fox (LUC recommends 50-foot buffer) 3) Habitat for songbirds and water fowl that occasionally use the area. Both the City's Natural Resource Depan Department and the Colorado Division of Wildlife recognize that this is a highly urbanized site with human activity and high traffic volumes in the immediate area even without the addition of the proposed JFK Plaza office project. The Division of Wildlife recommends that the fox den be filled this fall in order to discourage the fox from using it in next spring's breeding season. The DOW believes the best solution is to encourage the fox to move to a more appropriate location to rear it's young away from the dangers and disturbances associated with an urban site such as this one.
