PrtoJECT: 5303 Spine Road, Professional Office Building LOCATION: 5303 Spine Road, Lot 3, Gunbarrel Office Park APPLICANT: Dean Callen & Company Contact Person: David J. Blauch, Aquatic and Wetland Company (303.442.5770) Application Date: February 4, 2000 Application Fee Paid: $200.OQ Designated Wetland: Wetland #37, Alkaline Wetland on Heavy Clay Functional Values Provided by the Existing Wetland: Ground water rechazge, ground water discharge, flood storage, sediment trapping, long-term and short-term nutrient retention and removal, and within-basin food chain support. PROJECT/ACTIVITY DESCRIPTION: Proposed improvements on the property include the construction of a new 30,098 square foot, two story professional office building with associated parking. Development activities will d'uectly impact 1,621 square feet of the existing regulatory wetland buffer zone, including impacts for the construction of the building foundation, final grading and a second access drive from Gunpark Drive. Building and parking lot site development will not encroach into the regulatory wetland zone. However, site development includes an enhancement plan for the existing wetland and wetland buffer to improve functions to provide natural wetland habitat and stormwater runoff treatment from adjacent development. Wetland enhancement regrading is proposed to form a slight depression to recreate "historic-type" wetland conditions and will result in short term disturbance of 5,460 square feet of wetland azea and 16, 445 square feet of wetland buffer. WP00-OS.PMT WeT1.~ND PER~m' BASIS OF APPROVAL: Improvements encroaching into a wetland buffer area and enhancement of an existing regulatory wetland may be permitted under Section 9-12-8, "Standazds for Wetland Permits," Boulder Revised Code 1981 (B.R.C.), if the applicant has demonstrated: (a) that alI adverse impacts on a wetiand have been avoided through a reduct~on in size, scope or density of the project, or through a change in configuration or design, or that it is not feasible to do so; Adverse affects on the wetland have been avoided since site development improvements (re: buildings, parking and driveways) will encroach into th. ~~~-etland buffer area only and wil] not encroach into the regulatory wetland. In addition, enhancement of the existing wetland will improve wetland functions to the highly disturbed wetland that currently exists on the site. (b) that any impact on a wetland has been minimized, will resuit in minimal impact or impairment to any wetland function, and will not jeopardize the continued existence of habitat for identified plant, animal or other wildlife species; No adverse impacts to wetlands are expected from the proposed project, and the enhancement plan will improve the quality and function of the existing wetland. No adverse impacts to habitat for critical species are anticipated from the proposed project. (c) that the project is in the public interest, considering the public need, the functional values of the wetland that may be affected, the extent and permanence of any adverse effects and the cumulahve adverse effects of past activities on the wetland, and the uniqueness and scarcity of the wetland that may be affected. The proposed private development activity avoids direct impacts to the existing wetlands and proposes to enhance the quality and function of the existing wetland. Tn addition to wetland enhancement, the development activity will include storm runoff water quality improvements to treat drainage from this and adjacent developed properties. Considering the standards outlined under Section 9-12-8, staff finds that the proposed project meets the intent of 9-IZ-1, B.R.C. CONDITIONS OF APPROVAL: 1. All development activities impacting the wetland buffer and the wetland enhancement improvements shall conform with the "City of Boulder Wedand Permit Application" for Dean Callen and Company, prepared by Aquatic and Wetland Company, dated February 4, 2000. WP00-0S.PMT 2 Wert.~-ND Pee~-trr 2. The improvements shall avoid direct development impacts to the existing wetlands and shall comply with the "City of Boulder Wetlands Protection Program Best Management Practices (BMP's)" and "City of Boulder Wetlands Protection Program Best Management Practices: Revegetation Rules." 3. Wetland monitoring of the enhanced alkali flats wetland pond and wetland buffer area shall be performed for a minimum period of five years following completion of the project. Annual reports shall be submitted to the city for review providing an analysis of the ongoing quality and functions performed by the enhanced wetland. If the Floodplain and Wetlands Coordinator determines that unacceptable wetland impacts have occuned as a result of improvement activities in the regulatory wetland and wetland buffer, remedial wetland mitigation activities may be required to avoid wetland losses. NOTE: This permit expires three years after the date of final approval, pursuant to Section 9-12-12, "Expiration of Wetland Permit," B.R.C.
