CITY COUNCIL WORK SESSION Topic Report: Legacy Christian Academy By: Amber G. Miller, Planning Manager Background: Columbo Limited Partnership (Legacy Christian Academy) has applied for a major plat and request for site plan review for a new K -12 private school generally located generally located west of Armstrong Blvd, south of Alpine Dr and north of the railroad tracks. Additionally, they have also applied for rezoning to Public /Quasi Public in conjunction with a comprehensive plan amendment for a change in land use to Public /Quasi Public for the subject property. Engineering has also received a petition for a 429 project for the extension of utilities and roadway, the Petitioners are requesting that the improvements be designed, constructed and assessed to the Petitioners as the sole beneficiaries of the improvements. This document is attached for your review. The Project includes a major subdivision within the Pine Shadows Addition to accommodate a future 225,000- 275,000 square foot school. The Subject Property is 184.91 acres and is currently Zoned R -1 Residential, R -2 Residential, R -3 Residential and TC -2 Sub - District. The plat proposes to subdivide the parcel into three separate parcels, one lot and two outlots. Lot 1 is proposed to be 96.087 acres, 85.28 acres of which are proposed to be rezoned to Public /Quasi Public and require Comprehensive Plan Amendment, while Outlots A and B are proposed to be 35 acres and 45.196 acres, respectively. Additionally, there will be 8.635 acres of Right -of -Way. The site proposes one access from Armstrong Blvd where Bunker Lake Blvd would be extended as a local street within a 120' right -of -way. Upon development, Outlot A would access an improved Puma St and Alpine Dr, Outlot B would access from the extended Bunker Lake Blvd and potentially an improved Puma St. Full build out of Bunker Lake Blvd shows it as a four lane road with two lanes in each direction. The first phase proposes to construct one lane in each direction with a curb on the north side of the street and a shoulder on the south where the two lanes would eventually be added; applicant proposes a cul -de -sac just west of the softball fields, and a trail on the north side of Bunker Lake Blvd to Puma St and then north to Outlot A. Staff would like to have two lanes constructed all the way to Puma St, and improve Puma St to City standards all the way from Bunker Lake Blvd to Alpine Dr, including a trail. In addition, the westerly leg of the Bunker Lake and Armstrong Blvd intersection would need to be constructed full width, based upon the revised traffic analysis and ultimate intersection design. Consistent with the City's comprehensive trail plan and 2030 Comprehensive Plan, an off road trail easement is shown on the northern edge of the wetland on Lot 1 and the southern edge of Outlot A. However, it is shown as 10 feet and Staff would require it to be 20 feet in width. Municipal Water and Sanitary Sewer will be extended to serve the proposed subdivision from Armstrong Blvd. The cost of the utility extensions will be paid by the developer, with any oversizing necessary to serve the larger service district being paid by the City's corresponding Utility Funds.
