Garrett <br />Andy Mao <br />Connie Clark <br />Central File <br /> <br />SUBJECT: Canada Road from Fairmont Parkway to Spencer Highway" <br />Speed Study <br /> <br />Pursuant to your request, we have conducted an engineering study to determine the <br />appropriate speed limit on Canada Road from Fairmont Parkway to Spencer Highway, <br />within the qity of La Porte. <br /> <br />The speed limit recommended is based on the 85th percentile speed, along with <br />physical conditions, roadside development, potential pedestrian activity, and driveway <br />frequency. In accordance with data and other criteria, we recommend a 45-mph speed <br />limit on Canada Road from Fairmont Parkway north to approximately Defiance Street, <br />and a 35-mph speed limit north of Defiance Street to Spencer Highway. Appropriate <br />signing is in place, however, a Speed Reduction sign 0N3-5) is recommended <br />northbound, approximately 500 feet In advance of the change in speed (35 mph) north <br />of Defiance Street. No other changes are recommended. <br /> <br />TMUTCD:. Sectioll 2C.30 Speed Reduction Sign (W3-5) <br />Guidance: . <br />A Speed Reduction (W3.S) sign (see Figure 2C-S) should be used to inform road users of a reduced <br />speed zone when engineering judgment indicates the 'need for advance notice to comply.with the posted <br />speed limit ahead. <br />Standard: <br />If used, the Speed Reduction sigu shall be followed by a Speed Limit (R2-1) sign Installed at the <br />beginning of the zOlle where the speed limit applies. The speed limit displayed on tbe Speed Reduction sign shall be <br />identical to the speed limit displayed on the subsequent Speed Limit sign. <br /> <br /> <br />'. <br />" <br /> <br />, <br /> <br />S~ould you need additional information, please advise. <br />LSfCEC/mmm <br /> <br />RE.CElVEO <br />JUL Z 0 2009 <br /> <br />Debbie Valdez. <br /> <br />. . <br />t\cclark\p2\2009\canada,fnnnt to spencer speed.doc <br /> <br />0- .__--.._._u~~._.___..___._.....
