Highlands Ranch Stormwater & Sewer Project Review
Highlands Ranch, Colorado developers and property owners must follow county and state rules for stormwater control, sewer connections and project review. This guide explains the permitting pathways, who enforces standards, typical violations, and how to apply, appeal, or report problems for projects in Highlands Ranch.
Overview of Jurisdiction and Roles
Because Highlands Ranch is an unincorporated community, Douglas County is the primary permitting and enforcement authority for drainage, stormwater quality, and building/project review; state stormwater permits and water-quality rules also apply. For project-level sewer connections and sanitary service, local special districts and water/wastewater districts may hold authority; applicants should confirm the servicing district during early design review. See official county stormwater program for program details[1] and the county building division for permit submittal requirements[2].
Project Review Process
Typical project review steps for new development, major renovation, or site work affecting drainage or sewer systems:
- Pre-application meeting with Douglas County Land Use/Building Division to identify required studies and approvals.
- Submit civil/site plans including drainage report, erosion control plan, and stormwater quality BMPs as instructed by county reviewers.
- Technical review for compliance with county drainage standards, state MS4 or stormwater permit conditions, and any relevant special district rules.
- Address review comments, revise plans, and obtain approvals and permits before building or grading work begins.
Penalties & Enforcement
Enforcement for stormwater, drainage, and unauthorized sewer connections in Highlands Ranch is handled by Douglas County and, where applicable, by local utility or sanitation districts and state agencies for stormwater permit violations. Specific financial penalties and escalation details are not specified on the cited county pages; where state-level permit programs apply, state penalty provisions may also be relevant[3].
Key enforcement elements to expect:
- Monetary fines: not specified on the cited Douglas County pages; see the county or state permit pages for any published penalty schedules[1].
- Escalation: first/continuing/repeat offence processes are not detailed on the cited county pages.
- Non-monetary sanctions: stop-work orders, remedial construction, removal of noncompliant features, and referral to county attorney or courts are possible and are described as enforcement tools.
- Enforcer: Douglas County Land Use/Building Division and County Public Works/Water Resources for drainage and stormwater; local sanitation districts for sewer connections; state enforcement for MS4/permit violations[1][3].
- Inspections and complaints: report suspected illegal discharges or unpermitted work through the county complaint/contact pages; inspection procedures are managed by county staff.
- Appeals and review: appeal routes and timelines are handled under county land-use and permit appeal procedures; specific time limits for appeal are not specified on the cited county pages.
Applications & Forms
Most project reviews require a building or land development permit application and supporting documents. The county publishes application instructions and online submittal portals; specific form names or numbers are not consistently listed on the general program pages, so consult the county building division for current PDFs and e-permit links[2].
