Quick answer: what is Walnut Hills?
The WHCA website describes Walnut Hills as a subdivision of 1,177 homes in the City of Centennial in Arapahoe County, Colorado. The Walnut Hills Civic Association (WHCA) was incorporated in 1965 and is a registered 501(c)(4) community organization. Membership in the WHCA is open to residents and property owners of the subdivision.
A separate Walnut Hills General Improvement District (GID) maintains the subdivision's perimeter fencing and landscaping. The City of Centennial disburses GID funds upon recommendation and approval involving a GID representative and the WHCA.
Name note: other U.S. places also use the name Walnut Hills. This guide covers only the Centennial, Colorado subdivision described on the WHCA site.
Geography: City of Centennial, Arapahoe County
The WHCA describes Walnut Hills as a subdivision in the city of Centennial in Arapahoe County. Centennial's residents page describes General Improvement Districts as local taxing entities created to construct, operate or maintain specific public improvements or services within a district.
Confirm that a specific parcel sits in Walnut Hills and in Centennial using the Arapahoe County Assessor property search and Centennial's neighborhood / special-district maps.
Walnut Hills Civic Association (WHCA)
The WHCA represents community interests for Walnut Hills and is governed by bylaws; its board is composed of unpaid neighborhood volunteers. As of the WHCA dues page last captured Nov 3, 2026, annual membership dues were listed as $30.00 (April 1 to March 31); that capture also states they are not tax deductible. That figure is not confirmed for later dates - confirm the current amount and what membership covers with the WHCA before you buy. Dues support events and activities the WHCA organizes and give members the right to vote on issues that come before the association.
The WHCA dues page does not say whether membership is required to own a home in Walnut Hills, and it does not describe recorded covenants or a separate homeowners association. Covenant and HOA status for any address are UNVERIFIED on this page: verify with the WHCA and the Arapahoe County Clerk and Recorder before you rely on association or covenant claims.
General Improvement District (perimeter)
The Walnut Hills GID was created to maintain the periphery of Walnut Hills. Per the WHCA GID page, the District maintains all of the subdivision's perimeter fencing and landscaping; entry signs were constructed with District funds, and the page also notes sidewalk clearing along Arapahoe Road after a heavy blizzard and a 2011 fence replacement on Dry Creek and Quebec Streets.
The same page states that the City of Centennial disburses funds for District tasks upon recommendation and approval of a GID representative and the WHCA; the representative is appointed by the Centennial City Council. A GID line can appear on the property tax bill. We do not quote mill levies or dollar amounts; pull the current Arapahoe County tax bill and Assessor record for the parcel.

Local service links named by WHCA
The WHCA community-links page lists State and local government contacts including Arapahoe County and the City of Centennial, and under police, fire, health and safety it lists the Arapahoe County Sheriff and South Metro Fire District. It also lists South Suburban Parks and Recreation and the Arapahoe Library District among community links.
Those are community resource links, not verified service assignments for every parcel. Confirm fire, parks and library service for the exact address with the provider and with Centennial's special-district map.

The City of Centennial states that Littleton Public Schools and Cherry Creek School District serve Centennial residents. That citywide statement is not an address-level assignment for Walnut Hills.
Use each district's enrollment or school-assignment resources for the exact address, and Centennial's special-district map as a starting point. We do not rate schools or state assignments.
Property taxes and due diligence
Arapahoe County's Assessor and Treasurer publish property search, mill-levy / tax-district information and property-tax information for county parcels. Walnut Hills parcels may show a GID line on the tax bill in addition to other taxing authorities.
We state no mill levy or tax amount. Pull the Assessor record and tax information for the specific parcel.
What to request before you offer
Confirm the parcel is in Centennial Walnut Hills (not another place named Walnut Hills) using the Arapahoe County Assessor record.
Ask the WHCA what membership and documents apply today, and search Arapahoe County Clerk and Recorder records for any covenants or association filings that affect the address. Read the current tax bill for any GID or other special-district lines. Check school assignment by address with the district that serves the parcel.

Frequently asked questions
Is Walnut Hills inside the City of Centennial?
Yes. The WHCA website describes Walnut Hills as a subdivision of 1,177 homes in the city of Centennial in Arapahoe County. Confirm the parcel with the Arapahoe County Assessor.
Is this the same as other places named Walnut Hills?
No. This guide covers only the Centennial, Colorado subdivision described by the Walnut Hills Civic Association. Other U.S. communities share the name; do not mix their association rules or tax districts with this one.
How is Walnut Hills different from Willow Creek?
Both are in Centennial, but they are different neighborhoods with different association structures. Walnut Hills is described through the WHCA and a perimeter GID. Willow Creek is covered in a separate guide because it has its own association layout. Compare documents address by address; do not assume the same fees or rules.
What are the WHCA dues?
As of the WHCA dues page last captured Nov 3, 2026, annual membership dues were listed as $30.00 (April 1 to March 31) and not tax deductible. That figure is not confirmed for later dates - confirm the current amount and what membership covers with the WHCA before you buy.
Is there an HOA or recorded covenants?
We do not state HOA or covenant status from the WHCA pages alone. The dues and home pages describe a 501(c)(4) civic association and membership dues; they do not settle whether a separate HOA or recorded covenants bind a given lot. Verify with the WHCA and the Arapahoe County Clerk and Recorder.
What does the Walnut Hills GID pay for?
Per the WHCA GID page, the District maintains the subdivision's perimeter fencing and landscaping; it also describes entry signs, some Arapahoe Road sidewalk clearing and a past fence replacement on Dry Creek and Quebec Streets. Read the current tax bill and GID materials for the parcel; we do not quote mills or dollar amounts.
Which schools serve Walnut Hills?
Centennial's residents page says Littleton Public Schools and Cherry Creek School District serve Centennial residents. That is not a Walnut Hills assignment. Verify the district and schools for the exact address with those districts' locator or enrollment resources.
Where should I search for listings?
Use a citywide Centennial search (not a Walnut Hills-only filter). Our Centennial IDX results use the verified Centennial city filter and are not limited to Walnut Hills.
