Major Planning Cases

Current Land Development Cases Map

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.

Jefferson County Arcadia Creek Development

This proposed development is adjacent to the Arapahoe County/Jefferson County line, just west of Christensen Lane (the site address is 5234 W Leawood Drive, Littleton). The applicant is proposing a Planned Development zoning to allow up to 25 single-family homes, with private gated access off W Leawood Drive and W Christensen Lane. The applicant indicated that they will be marketing the homes to people who are 55 years or older. If the Jefferson County project is approved, the developer plans to subdivide 5100 W Christensen Lane in Arapahoe County to create one additional home site; that application will likely be submitted after Jefferson County acts on the proposed Planned Development zoning.
This is a Jefferson County rezoning case, so any comments or questions should be addressed to Justin Montgomery, the Jefferson County project manager. Jefferson County will hold public hearings regarding this project at some point in the future. We will update this page when we know the date.

Skyview Village Townhomes

Alpert Development is proposing 29 townhome units to be located at 1650 South Quebec Way, just south of the Brookdale Highline assisted living facility and southwest of the Highline Canal Trail. The property is currently zoned as a Senior Housing Planned Unit Development (SH-PUD); the zoning allows up to 100 nursing care units at a density of up to 40 dwellings/acre. The applicant is proposing a rezoning to allow 14.5 dwellings/acre on the 2-acre site.  
If you would like more information about the Preliminary Development Plan, please contact Molly Orkild-Larson, Arapahoe County Senior Planner.  

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.
