Current Land Development Cases

Arapahoe County's Planning Cases map displays all land development cases actively under review in unincorporated Arapahoe County.  



Land Development Code Update

Arapahoe County is updating its land development code to improve our process and offer alternatives to Planned Unit Development zoning. Please visit our Land Development Code Update page for more information about the project, including the approved Planned Unit Development regulations.

Prospect Village/Lugano Waffle House Specific Development Plan (Case SDP18-001)

This project is located west of the intersection of E Iliff Avenue and S Dayton Way on a vacant pad site in the Prospect Village/Lugano development. The Board of County Commissioners approved the original Final Development Plan for this site in March, 2009. The applicant proposes reducing the pad site building square footage, modifying the building architecture, and allowing a 24-hour restaurant (with no drive-through or outdoor seating). The Planning Commission denied this application on Tuesday, October 16, 2018. The applicant submitted a letter objecting to the Planning Commission decision and asked the Board of County Commissioners to hold a public hearing on this case. If the Board decides to hold a public hearing, we will post the date and time here. For information on this case, you may contact Kat Hammer, case planner.  

Houlihan Pipeline (Case UASI18-002)

This project is located south if Interstate 70 along the Cavenaugh Road and S Manilla Road alignments east of Watkins. Discovery Midstream Partners proposes the construction of a natural gas pipeline to facilitate and deliver natural gas and crude oil to regional markets. The proposed pipeline originates at an Extraction oil pad site in Arapahoe County and continues north to Discovery's facility in Weld County. The Planning Commission public hearing for this proposal will be on November 6, 2018 at 6:30 p.m. The hearing will be in the East Hearing Room of the Arapahoe County Administration Building, 5334 S Prince Street, Littleton CO 80120. For information on this case, please contact Diane Kocis, Arapahoe County energy specialist.

ConocoPhillips is proposing one well and four 500 BBL low-profile tanks, along with other supporting equipment. If you have any questions, you may contact Diane Kocis, Arapahoe County Energy Specialist.

Prosper Development

Arapahoe County is currently reviewing a number of cases related to the Prosper development located south of Interstate 70 and N Watkins Road. These cases will eventually have public hearings and we will post the dates as soon as we know them.

The County approved the initial zoning - the Prosper Preliminary Development Plan (PDP) - in early 2015. When fully developed, the Prosper development will cover 5,130 acres (8 square miles) and will include up to 9,000 housing units and 8 million square feet of commercial/office/industrial uses. If you'd like to review the entire Prosper PDP you can download the very large PDP (180 MB) here. You may also download the much smaller Prosper land use plan for an overview of the project.

Initial phases of the Prosper development will rely on Denver Basin aquifer ground water. However, the development will eventually use a combination of renewable surface water, reclaimed wastewater, and lawn irrigation return flow. Per the Prosper water supply plan (70 MB file), when fully developed, 73% of the water in Prosper will be from those renewable sources.

Prosper Water Treatment Plant - The County is currently reviewing a permit for Prosper's initial water treatment plant. This Location & Extent document shows where it's located and what it will look like. The Board of County Commissioners approved the plant on June 27, 2017.

Prosper Preliminary Plat and Final Development Plan - This is the first phase of the project, located east of N Watkins Road. The Final Development Plan includes 977 single-family homes on 754 acres of land. The Final Development Plan includes proposed landscaping and design standards for the potential homes. The preliminary plat shows more detail on the lot layouts. The applicant's letter of intent offers a general overview of the project. The Board of County Commissioners approved both of these items on August 15, 2017.
