Six fundamental problems with how development is proceeding on NE 174th Street
NE 174th Street is less than 20 feet wide with no sidewalks, shoulders, bike lanes, lighting, or curb and gutter. At 300+ projected homes and ~3,065 daily trips, it should meet Neighborhood Circulator standards (32–36 ft minimum with sidewalks on both sides). The gap is at least 12 feet of pavement width and all pedestrian infrastructure.
County code requires secondary emergency access when more than 100 lots are served by a single access road. With 300+ projected lots and no secondary access, this requirement has been acknowledged but never enforced. The 174th Street Subdivision PAC report (item 13) itself flags this as exceeding the 100-unit maximum for single-access roads.
Each development is evaluated in isolation. Cumulative road impacts are never assessed. Road improvement deferrals are granted project by project. The result: 300+ homes approved on infrastructure that has historically served approximately 20.
Private roads and gated access reduce the road width, sidewalk, and bike lane standards that apply to the development. The HOA assumes maintenance liability while the county collects property taxes but does not require public infrastructure standards. Residents pay higher HOA dues for roads the county should have required to public standards.
Clark County Code explicitly allows denial of development when off-site road conditions create “a significant traffic or safety hazard” (CCC 40.350.030(B)(6)(a)). The county’s own PAC reports acknowledge inadequate infrastructure. Yet every application has been approved or advanced.
A retired professional engineer (Dean Hergesheimer) has spent years and tens of thousands of dollars challenging approvals through hearings, appeals, and lawsuits. A hearing examiner initially ruled in residents' favor, then reversed. Fire officials say their "hands are tied." Even Councilor Sue Marshall acknowledges the problem in writing — yet projects continue to advance.

Documented instances where county staff interpretations departed from the plain text of code requirements
The county’s second access requirement (100-lot limit for single-access roads) exists to prevent stranding hundreds of residents without fire, medical, or law enforcement services if the only route is blocked. The developer’s attorney argued that because 174th Street is planned for future widening to 34 feet with sidewalks, the subdivision is exempt from this requirement today. The county accepted this argument, approving development based on a road that does not yet exist.
County staff claims that NE 174th Street's traffic capacity changes by 400% — or even 2,400% — simply because it is classified as a "public" road rather than a "private" road. The physical road is identical on both sides of the public/private boundary. There has never been an explanation of how ownership classification changes a road's actual traffic capacity. This directly contradicts explicit county code language: "the capacity shall be determined based on the current roadway condition."
County code limits vehicle traffic on 20-foot-wide roads without pedestrian facilities to the amount created by 50 lots. With the M&H Subdivision alone, 120 lots are served by 174th Street as their only access route — more than double the code limit. With all approved and pending projects, 300+ lots will use this road. The county has never explained how this complies with its own standards.
County engineer Rob Klug recommended a 35 mph speed limit for NE 174th Street based on its proposed future width of 34 feet. County code specifies 25 mph for 20-foot-wide roads. The road has not been widened. The speed limit was set for a road that does not exist.
Some homes on single-access roads are required to have fire sprinkler systems — but Clark County has relaxed this requirement for new development. Why? Sprinklers in new homes do nothing for existing residences, which now face reduced protection due to increased density and response time constraints. And sprinklers do nothing to address evacuation, medical emergencies, or law enforcement access — the other critical reasons the second access requirement exists. A sprinkler system doesn’t help when the only road out is compromised by fire, a fallen tree, or a downed power line.
The county's arterial atlas classifies NE 179th Street as a 4-lane Principal Arterial (Pr-4cb) with a capacity of 1,800 vehicles per hour. The road is actually a 2-lane rural road with an actual capacity of 600–800 vehicles per hour. This inflated classification is used directly in every concurrency calculation, doubling or tripling the capacity denominator and making it nearly impossible for any road segment to show failure. Five independent traffic studies — commissioned by five different developers — all find the same road segments exceeding the county's 0.90 failure threshold even with the inflated numbers. At actual road capacity, the true volume-to-capacity ratios would exceed 2.0 — meaning traffic demand is more than double what the road can safely carry.
On May 5, 2021, county community development engineer David Bottamini issued a memo concluding that the existing narrow roads are safe to handle all additional traffic — notwithstanding the following conditions: a road less than 20 feet wide with no sidewalks, no shoulders, and pedestrians forced to walk in the travel lane. This memo became the key document cited to justify the hearing examiner’s reversal and to defeat the neighbors’ $17,000 court challenge.
Ask #1 — Read the Existing Traffic Studies. Act on the Facts.
"I am asking Clark County to read, understand, and act on the traffic studies it already has. Seven independent traffic impact studies submitted between 2023 and 2025 — commissioned by different developers, prepared by different engineering firms — all document the same failures on NE 174th Street and the NE 179th Street corridor. A community analysis of those studies is compiled at 179gridlock.com. Another study is not needed. Clark County needs to base its decisions on the facts already in its own files and stop approving development that the existing studies show the roads cannot safely support."
Ask #2 — Preserve the Mill Creek Overlay District
"I am asking the Council to preserve the Mill Creek Overlay District (CCC 40.250.060) and its current standards, including the 9,000 sq ft minimum lot size (Standard C.3) and the requirement for additional public road access before new development is approved (Standard C.2). This overlay was created in 2009 through two years of community engagement specifically because the area has environmental constraints and only one road in and out. The proposed upzoning to R1-7.5 would increase allowable density by 4.5 times on infrastructure the county itself recognized as inadequate in 2009. The overlay should not be weakened or bypassed through the Comprehensive Plan update."
The Real Ask
We are not opposed to growth. The real ask is simple: we are asking Clark County to do its job — to pursue responsible development with a genuine focus on community access, transportation safety, sidewalks, bike lanes, and adequate road infrastructure, while also protecting and preserving the environmentally sensitive areas that the county itself identified when it created the Mill Creek Overlay District.
