Rampart Range Metropolitan District No. 1-9

Rampart Range Metropolitan District Nos. 1- 6 ("RRMD") were formed on September 22, 2000 and approved by the City of Lone Tree. In 2005, District Nos. 7-9 were formed. District No. 9 is currently inactive. The West side is comprised of District Nos. 1, 2, 3 & 7. The East side is comprised of District Nos.  4, 5, 6, 8 & 9. All districts are in the RidgeGate Community.  

RidgeGate™ is a mixed-use, master planned community in Lone Tree, Colorado. Our community is nearly fully developed on the west side of I-25 and is now expanding to the east side of I-25, encompassing a total of 3,500 acres or six square miles. Both the east and west sides of RidgeGate are designed to integrate natural and urban amenities. So residential neighborhoods are tucked next to beautiful natural open space, parks and trails. Dynamic shopping, dining, wellness and business districts are accessible and walkable.


The Districts were organized to serve the infrastructure needs of the new development and as such the purpose is to plan for, design, acquire, construct, install, relocate, redevelop and finance the public improvements. Rampart Range is generally located south of Lincoln Avenue and East of Yosemite in Lone Tree and consists of approximately 3,353 acres. It consists of several development areas planned for residential and commercial development. The Metro Districts are a multiple District structure that has RRMD No. 1 as the “service” district to manage the construction and operation of facilities and improvements needed and RRMD Nos. 2-9 as the “financing” districts, responsible for the funding and tax base needed to support the financing plan for capital improvements.

Ongoing service responsibilities of the District are limited to parks and recreation, drainage, and streets until acceptance by the City. RRMD water and sewer service is provided by Southgate Water and Sanitation.
