At a public hearing on July 19, 2012, Planning Commission voted to recommend approval of the proposed ordinance; meeting minutes are attached. The ordinance was introduced on first reading on August 13, 2012. FINANCIAL IMPACT: The proposed ordinance is not expected to have a financial impact on the City. Council Action Form August 27, 2012 Page 2 When the zoning code was repealed and reenacted in 2001, the lower limit of the clear zone was reduced from 42 inches to 36 inches for sight triangles along arterial and collector streets. The standards related to sight triangles and clear zones have not been amended since 2001. Additionally, the location of the sight triangle does not currently align with the location from which the vertical clear zone is measured —the latter is measured vertically from the curb and gutter flow line or from the edge of pavement if no curb is present. The proposed method for measuring the sight distance triangle is along the flow time or edge of pavement which can be easily located in the field and will result in a sight distance triangle that is positioned at the true corner of intersection. The length of the sight distance triangle depends on the type of intersection, and there is no change proposed for those measurements. m Property Line-, IJ 25' A. The sight triangle is currently measured along the property line which is difficult to field locate. Council Action Form August 27, 2012 Page 3 l 7 ertical Clear one The vertical clear zone is the area above the sight distance triangle. The clear zone needs to remain free from obstruction in order to provide drivers with a clear view of approaching motor vehicles, bicycles, and/or pedestrians. Currently, the vertical clear zone is measured from the flow line or edge of pavement, and there is no change proposed to this method of measurement. For intersections that include a collector or arterial street, the lower limit of the clear zone is currently regulated at 36 inches. The lower limit for all other clear zones is 42 inches above the flow line or edge of pavement. There is no change proposed for these lower limits. . .... .. . ...

Sight Triangles in Other Communities The proposed code amendment is consistent with the sight triangle standards of other Front Range communities. Of the 16 communities surveyed, ten establish an upper limit for the vertical clear zone at 96 inches or higher. Twelve communities clearly state that the sight distance triangle is located along the curb line, flow line or edge of pavement. The proposed changes to section 26-603.G.2 of the code will remove from the zoning code the six-foot height requirement for swimming pools and will instead defer to the International Residential or Building Code, as applicable. Next Steps: Implementation and Eqt6rcentent Staff has met with the Forestry Division and with Community Service Officers to discuss the implementation and enforcement of the proposed sight triangle standards. Both divisions Council Action Form August 27, 2012 Page 4 support the proposed code amendments and agree that the sight distance triangle will be easier to locate in the field and easier to communicate to citizens. Staff reco&niizes that for some tree species or for immature trees, trimming to 96 inches will be inappropriate, so discretion will be used to reasonably enforce the new standard. Code enforcement officers have confirmed enforcement will continue primarily on a complaint basis. In the case of public safety hazards, enforcement will be proactive. If the proposed code amendment is approved, public outreach and education will help to reduce violations—an interdepartmental strategy is proposed to include new informational handouts, an article in the Connections newsletter, and/or a Top oft e Hour segment on Channel S. RECOMMENDATIONS: Staff recommends approval of the ordinance. Ultimately, this code amendment will improve clarity and consistency in the City code. The amendment will align the vertical clear zone with national safety standards and will improve the ability to explain and field locate a sight distance triangle.

She entered all pertinent documents into the record and advised the Commission there was jurisdiction to hear the case. She reviewed the staff report and digital presentation. Staff recommended approval for reasons outlined in the staff report. Staff proposes amending section 26-603 (Fences, walls, and obstructions to view) of the city code which relates primarily to sight distance triangles. The proposed amendment will improve the ability to field locate a sight distance triangle, update the vertical clear zone dimensions to align with national standards, and standardize the method of measurement for the sight distance triangle and clear zone.

In the mid- I 990s, proposed code amendments sought to address conflicting 4- - height standards established in four se arate code sections Case Nos. ZOA-93-01 a fflff� F4 ZOA-1 1-06 / Sight Triangle clear zone. The contents of the case file do not indicate why the upper limit of 84 inches was ultimately selected in 1996. When the zoning code was repealed and reenacted in 2001, the lower clear zone limit was reduced from 42 inches to 36 inches for sight triangles along arterial and collector streets. New language was added to clarify that the clear zone is measured from the flow line or edge of pavement; previously, the code did not establish a location for this measurement. The standards related to sight triangles and clear zones have not been amended since 2001. Additionally, the location of the sight triangle does not currently align with the location from which the vertical clear zone is measured—the latter is measured vertically from the curb and gutter flow line or from the edge of pavement if no curb is present. The proposed method for measuring the sight distance triangle is along the flow line or edge of pavement which can be easily located in the field. This method of measuring will also result in a sight distance triangle that is positioned at the true comer of intersections, providing a more logical clear area for drivers, bicyclists, and pedestrians. The length of the sight distance triangle depends on the type of intersection, and there is no change proposed for those measurements. A.

In the Wheat Ridge Municipal Code, regulations pertaining to the sight distance triangle are located in subsection B of section 26-603 (Fences, walls, and obstructions to view). 'File dimensional standards are currently embedded in long paragraphs of text, and the subsections do not have headings. A code amendment is proposed that modifies only subsection B, related to sight distance triangle requirements. The proposed modifications provide a definition, dimensional standard, method of measurement, and diagram for the horizontal sight triangle area and vertical clear zone, respectively. The revision will address these central goals: • Improve the ability to field locate a sight distance triangle; • Update the vertical clear zone dimensions to align with national standards; • Standardize the method of measurement for the sight distance triangle and clear zone; and • Improve clarity and organization within the zoning code. For your review, please find attached a copy of the current code (section 26-603) and a footnoted draft of the proposed revisions for section 26-603.13. Discussion of the proposed code amendment will take place on Wednesday, May 16 at the 2:00pm Micro Development meeting. Alternatively, please feel free to contact me directly to provide comment. The proposed amendment is scheduled to be presented to City Council at a study session on Monday, June 18. Changes to the Sight Distance Triangle The code establishes a sight distance triangle as the horizontal area at the intersection of two streets; a street and an alley; or a street and a driveway, Currently, the sight distance triangle is measured along the property line or right of-way line as shown in the image on the following page. This method makes it nearly impossible to field locate the sight distance triangle and, in some cases, the triangle area can encroach severely onto private property. Additionally, the location of the sight triangle does not currently align with the location from which the vertical clear zone is measured--the latter is measured vertically from the flow line or edge of pavement.

Obstructions oil lot B may affect the resident of lot A, but the exemption prevents any enforcement of the sight triangle regulations. Please be prepared to briefly discuss this exemption and whether or not it should remain. Attachments 1. Original code, section 26-603 2.

Most references should be hyperfinked to the original source (code or manual), As we've discussed, updates could address: - location of sight triangle (at flow line/edge of pavement instead or ROW/lot line) - standardize the lower limit for all types of streets (currently at 36" for some and 42" for others) - change the upper limit to reflect AASHTO standards - provide a better diagram to reflect updated codes - clarify applicability at signalized intersections T 74 fd I fg I UY CT I 7M standards, but I'm sure you guys can speak to those issues.

In making this determination, it should be assumed that the driver's eye is 1 080 mm [3.5 ft] above the roadway surface and that the object to be seen is 1 080 above the surface of the intersecting road. Where the sight-distance value used in design is based on a single-unit or combination truck as the design vehicle, it is also appropriate to use the eye height of a truck driver in checking sight obstructions, The recommended value of a truck driver's eye height is 2330 mm [7.6 ft) above the roadway surface WM M ..
