Draft Environmental Impact Statement, Blue Water Bridge 3.8 Aesthetic and Visual Impacts The Federal Highway Administration’s (FHWA) Technical Advisory T6640.8A (TA) dictates that whenever a potential for visual impacts exists from a proposed transportation project, the environmental study should identify the potential visual impacts to the adjacent land uses as well as measures to avoid, minimize, or mitigate these potential visual impacts. The visual assessment process consists of four study components. These include: • Determining the existing Landscape Viewshed What Are Context • Analyzing the Landscape Character and Experience Sensitive Solutions (CSS)? • Predicting Baseline Impacts • Identifying Mitigation Options FHWA defines CSS as “a collaborative, The visual assessment process provides an analysis of the interdisciplinary approach that involves all landscape character for the Study Area.

The Study Area and surroundings are best described (from east to west) as an urban area that begins transitioning to a more suburban less populated area as the viewer proceeds west through the study corridor. Residential and commercial properties are the most dominate land uses in the Study Area. Single‐family homes make up the majority of the residential land uses, while business properties are prevalent along Pine Grove Avenue and near the Water Street Interchange. Public land uses include parks, a public campground, and a Michigan Welcome Center, all located west of the Black River Bridge. Blue Water Bridge Plaza Study Draft Environmental Impact Statement 3.8-1 3.8 Aesthetic and Visual Impacts The Study Area is mostly flat with the exception of the Black River and Stocks Creek crossings which are low lying areas. The area around the Black River gently slopes toward the river creating a visual experience that differs from the rest of the corridor. The western edge of the Study Area past the Water Street Interchange, which includes Stocks Creek, exists in more of a natural state than the remainder of the corridor. There are small woodland areas along with open areas of old fields and meadows. As one approaches Port Huron from the west, the trees and natural features are replaced with signs, billboards, power lines, streetlights, and commercial businesses. There are a few key land uses within the Study Area that contribute to the visual identity of the area. The most Area Around Existing Plaza significant of these are the Black River, adjacent marinas and parks. A public campground, owned and operated by Port Huron Township, is located on the north side of the freeway west of the Water Street Interchange. Residences are an important land use near the existing plaza. Their view includes an elevated plaza approximately 24‐feet high with associated buildings and traffic. In the area dedicated to the new plaza in Port Huron Township, there are single‐family residences located to the north and south of the existing freeway, a mobile‐home park located further southwest, a large church located north of the freeway west of Stocks Creek, and a school located south of the freeway west of the Lapeer Connector. Residences in the Township area currently do not have a view of the existing plaza, but do have a view of the I‐94/I‐69 freeway and the associated traffic. The visual quality of an area may depend on the preferences and subjective values of the viewer. FHWA produced a manual titled Visual Impact Assessment for Highway Projects to assist in evaluating the visual qualities of a Study Area. In order to complete the analysis, the Study Area was divided into four areas that display consistent visual characteristics and a uniform visual experience which are called “Visual Assessment Units” (VAU). Each VAU may be thought of as outdoor room that has a direct relationship to the natural layout of the area and associated land uses. The boundaries of these visual environments occur where there is a change in visual character. The strongest determinations of the visual 3.8-2 Blue Water Bridge Plaza Study Draft Environmental Impact Statement 3.8 Aesthetic and Visual Impacts boundaries are topography and landscape components. The four VAUs (Figure 3.8.1) within the Blue Water Bridge Plaza corridor have the following characteristics and include: • VAU‐1, Port Huron Township – This VAU consists of generally old field/meadow with some woods and low lying areas. Several billboards along with powerlines and a MDOT maintenance building make up the landscape. There is a cluster of single‐family residences visible in the distance to the north and a mobile home park located just Highway median in VAU-1 off of I‐94/I‐69 to the southwest. • VAU‐2, Water Street/Lapeer Connector Area – The area in and around this VAU consists of gently rolling terrain that is dominated by constructed elements. As the viewer travels from west to east, through this VAU, the area transitions from a rural to urban landscape. Views from I‐94/I‐69 are of billboards and signs promoting local businesses. • VAU‐3, Black River Area – The sloping terrain of the I-94/I-69 in VAU-2 Black River constitutes VAU‐3. The dominant feature in this VAU is the I‐94/I‐69 crossing of the Black River. The crossing is surrounded by marinas, public parks, several residences, a condominium building, and commercial establishments that overlook the river valley. • VAU‐4, Existing Plaza Area – The visual center of this VAU is the existing Blue Water Bridge Plaza. The elevated plaza dominates the views in this VAU. The plaza itself eliminates most of the views from the street level View of the Black River Bridge in VAU-3 surrounding the plaza. However, there are excellent views of the surrounding neighborhoods and businesses from the plaza. The visual quality rating of the visual environment in each VAU can be collectively defined using the attributes of vividness, intactness and unity—each of which is evaluated independently. The visual landscape is also divided into three parts for the evaluation: • Foreground zone – 0.25 to 0.5 miles from the viewer, View from Plaza in VAU-4 • Middle ground zone – extends from the foreground zone to three to five miles from the viewer, Blue Water Bridge Plaza Study Draft Environmental Impact Statement 3.8-3 3.8 Aesthetic and Visual Impacts 1/2 402 g For Con da er t na 1/4 v Feet 0.25 Omar Ont Ca 1,050 ario, i Miles ir R Michigan Blue la Water C Huron Beers Wright Bridge t.

  • Blue Water Bridge FEIS Executive Summary
    EXECUTIVE SUMMARY This Final Environmental Impact Statement (FEIS) discusses the Recommended Alternative for improving the United States Inspection Facility at the Blue Water Bridge Plaza and the I‐94/I‐69 corridor in St. Clair County, Michigan. This project is commonly referred to as the Blue Water Bridge Plaza Study. The Final EIS was prepared as a Condensed Final EIS. This approach avoids repetition of material from the Draft Environmental Impact Statement (DEIS) by incorporating, by reference, the DEIS resulting in a much shorter document than under the traditional FEIS approach. This document still provides the reader with a complete overview of the project and its impacts on the human and natural environments. This FEIS focuses on changes in the project’s setting, impacts, technical analysis, and mitigation measures that have occurred since the DEIS was circulated. What is the United States Plaza at the Blue Water Bridge? The United States Plaza, which is owned by the Michigan Department of Transportation (MDOT), is the inspection facility for vehicles entering the United States. The Blue Water Bridge is a major border crossing for cars and trucks between the United States and Canada. The Blue Water Bridge consists of two bridge spans over the St. Clair River, one for traffic to Canada and one for traffic to the United States. The bridges are jointly owned by MDOT and Blue Water Bridge Canada (BWBC). Federal agencies operating on the plaza include the Bureau of Customs and Border Protection (CBP), the United States Department of Agriculture (USDA), and the United Existing United States Blue Water Bridge Plaza States Food and Drug Administration (FDA).

  • Light Pollution by Stephen Davis − 2/26/08
    1 Prepared for SAB's review of EPA "Report on the Environment (2007)" [minor changes 3/11/08] Light Pollution by Stephen Davis − 2/26/08 One thing the EPA has been pushing is its "Green Lights" program. Using energy efficient light bulbs is not good enough: a) When too much light is being used, b) When aimed improperly, or c) When nobody is there to use it.[1] This is "Light Pollution!" And there is way too much of it costing the USA some $4.5 billion or more annually. This energy and money could be put to far better use. [2,3] Light Pollution and all its ramifications are missing from the EPA "Report on the Environment."[4,5] The #1 and #2 problems in Congress, needing immediate attention, are the economy and climate change. Both are directly related to energy independence and homeland security.[6] There is a connection between Light Pollution and what Congress considers as in our best interests. Unfortunately, government hasn't been watching were the money goes and how it is spent. We need accountability[7,8] and awareness[9] at all levels right down to the common man on the street before it's too late and we are all looking for life boats. What happened to "conservation" − the word that is never to be spoken?[10,] What if the money and other resources aren't there, or could they be put to better use elsewhere? The federal government can lead the way and get others involved through policy, guidance, and monitoring.

  • Students' Opinions on the Light Pollution Application
    International Electronic Journal of Elementary Education, 2015, 8(1), 55-68 Students’ Opinions on the Light Pollution Application Cengiz ÖZYÜREK Ordu University, Turkey Güliz AYDIN Muğla Sıtkı Koçman University, Turkey Received: June, 2015 / Revised: August, 2015 / Accepted: August, 2015 Abstract The purpose of this study is to determine the impact of computer-animated concept cartoons and outdoor science activities on creating awareness among seventh graders about light pollution. It also aims to identify the views of the students on the activities that were carried out. This study used one group pre-test/post-test experimental design model with 30 seventh graders. The data in the study were collected via open-ended questions on light pollution and semi-structured interview questions. The open-ended questions on light pollution were administered as a pre-test and a post- test. After the post-test was administered, semi-structured interviews were conducted with seven students. The data collected from the open-ended questions and semi-structured interviews were qualitatively analysed and quotes from the students’ statements were included. Looking at the answers of the students to questions on light pollution, it was understood that the activities that were carried out were effective. Furthermore, all of the students that were interviewed made positive statements about the activities that were carried out. Keywords: Light pollution, Concept cartoons, Students’ views. Introduction Humans are an indispensable part of the environment that they live in. Due to the rapid increase in population, overurbanization, industrialization and, consequently, the excessive use of natural resources, today, environmental issues have become global issues.

Biorąc pod uwagę oczywisty fakt, że pożywieniem zooplanktonu jest fitoplankton, postawiono hi- potezę o możliwej korelacji między jasnością nocnego nieba a zawartością fitoplanktonu w warstwach powierzchniowych zbiornika wodnego. W celu weryfikacji tej hipotezy wykonano całoroczne pomiary jasności nocnego nieba w rejonie uję- cia wody na Zbiorniku Dobczyckim. Stwierdzono wyraźną liniową korelację między poziomem chlorofilu a w warstwach powierzchniowych tego zbiornika a jasnością nocnego nieba. Nie stwierdzono jakichkolwiek podobnych korelacji między poziomem chlorofilu a a innymi wskaźnikami jakości wody, takimi jak temperatura czy natlenienie, jak również z parame- trami meteorologicznymi, takimi jak temperatura powietrza czy nasłonecznienie w ciągu dnia. Postawiono tezę, że jasność nocnego nieba, na którą składają się zarówno czynniki naturalne (światło Księżyca), jak sztuczne (zanieczyszczenie świetl- ne w postaci sztucznej poświaty niebieskiej), jest głównym i decydującym czynnikiem wpływającym na rozwój glonów w warstwie powierzchniowej Zbiornika Dobczyckiego. Postawiono tezę, że poprawne oświetlenie okolic ujęć wody może znacząco obniżyć eutrofizację zbiorników wodnych.

Environmental Health (2020) 19:74 https://doi.org/10.1186/s12940-020-00628-4 RESEARCH Open Access A large prospective investigation of outdoor light at night and obesity in the NIH-AARP Diet and Health Study Dong Zhang1* , Rena R. Jones2, Tiffany M. Powell-Wiley3, Peng Jia4,5, Peter James6 and Qian Xiao7 Abstract Background: Research has suggested that artificial light at night (LAN) may disrupt circadian rhythms, sleep, and contribute to the development of obesity. However, almost all previous studies are cross-sectional, thus, there is a need for prospective investigations of the association between LAN and obesity risk. The goal of our current study was to examine the association between baseline LAN and the development of obesity over follow-up in a large cohort of American adults. Methods: The study included a sample of 239,781 men and women (aged 50–71) from the NIH-AARP Diet and Health Study who were not obese at baseline (1995–1996). We used multiple logistic regression to examine whether LAN at baseline was associated with the odds of developing obesity at follow-up (2004–2006). Outdoor LAN exposure was estimated from satellite imagery and obesity was measured based on self-reported weight and height. Results: We found that higher outdoor LAN at baseline was associated with higher odds of developing obesity over 10 years. Compared with the lowest quintile of LAN, the highest quintile was associated with 12% and 19% higher odds of developing obesity at follow-up in men (OR (95% CI) = 1.12 (1.00, 1.250)) and women (1.19 (1.04, 1.36)), respectively.

  • Border Crossing Freight Travel Time and Delay
    Final Site Report EVALUATION OF TRAVEL TIME METHODS TO SUPPORT MOBILITY PERFORMANCE MONITORING BLUE WATER BRIDGE To Office of Freight Mgt. and Operations Federal Highway Administration U.S. Department of Transportation Washington, DC 20590 April 2002 Border Crossing Freight Delay Data Collection and Analysis FY 2001 Data Collection – Blue Water Bridge Site Description The Blue Water Bridge connects Port Huron, Michigan with Point Edward and Sarnia, Ontario and crosses the Saint Clair River. The bridge is near the intersection of I-94 and I-69 in the U.S., connecting with Detroit and Flint, Michigan and Chicago, Illinois. In Canada, the bridge connects with Highway 402, a major highway that connects to Highway 401 in London, Ontario, which extends from Detroit, Michigan through Toronto, Ontario and into the Eastern Provinces. The bridge facilitates the movement of many commodities between the U.S. and Canada, with the automotive and agricultural industries the most notable. The bridge operates 24 hours a day, seven days a week. The Blue Water Bridge comprises two spans, each with three lanes. The original bridge, built in 1938, was refurbished in 1999 and handles westbound traffic into the U.S. The second span, opened in 1997, handles outbound traffic into Canada. The bridge is open for both passenger and commercial vehicle traffic 24 hours a day. The bridge is unique in that it is not jointly owned by entities on both sides but, rather, the U.S. side of the bridge is owned by the State of Michigan and operated by the Michigan Department of Transportation and the Canadian side is owned and operated by the Blue Water Bridge Authority.
