These surrounding subdivisions successfully utilize on-site water wells and septic systems. Denaly Estates Subdivision will also utilize on-site systems. A large number of test holes have been completed the past several years within the proposed subdivision. Over 70 test holes reveal a similar soil. The soil is generally sandy with some gravel and silt. This soil is typical for the Eagle River valley; ablation glacial till. Most of the test holes exhibited groundwater at depth. Some test holes revealed shallower groundwater, but meeting the minimum requirements. The soils in this latest phase of Denaly Estates Subdivision have generally been found to be consistent with the soils in the surrounding subdivisions. The soils were placed as glacial till, and are predominately sand,silty sand,silts,and gravel.Bedrock was not encountered in the test holes. Groundwater is not an issue; all the test holes have adequate separation to groundwater. Most test holes exhibited no groundwater.The test holes,septic system reserve area,and possible water well locations have been depicted on the accompanying drawing. Drainages have been mapped for the subdivision. Drainages consist of typical mountain run-off, directed toward Eagle River. Most drainages ultimately reside underground, due to the highly permeable soil. The soils logs completed have been predominately found to be consistent with MOA requirements for on-site systems. Soil and percolation tests have been completed over the past 16 years-these have been compiled, field-checked and included in the soils report. Some minor errors have been noted in the percolation test results;these are not significant and do not reveal any inconsistencies in this subdivision phase. Percolation tests over the years have not consistently followed the requirement for measuring to the nearest one-sixteenth inch or for one-hour in duration-these omissions do not appear to effect the adequacy of the soils. A large utility easement crosses the northern tier of proposed lots. This easement required special scrutiny in placement of septic reserve sites and proposed water wells. The septic system reserve site for Lot 13 straddles the utility easement;the large size of the reserve area allows adequate development without impacting the utility easement. Other lots along this easeartCn la4�wise allow development without impacting the utility easement. .�.��. Cqs, / Zyn 4 �• VIJ 411411W A �, ..

(Eklutna) contracted TERRASAT, Inc. (TERRASAT) to evaluate ground water quality and resources beneath the Den aly subdivision and surrounding properties. TERRASAT examined the most current publicly available information for: • Well logs for water wells within a 1/2 mile radius of the property, including some that are not within the public record; • Municipality of Anchorage On-site Inspection report files (including engineer's well yield tests) Included as background information in this report is information and analyses from these sources: • Stereo aerial photographs (both low altitude high-resolution and high altitude color infrared) stereo aerial photography; • Available geologic and hydrologic maps and reports compiled by the United States Geological Survey for the area; The results of this investigation consists of data interpretation and correlations that are presented in a geographical information system (GIS) format. Tables and text within the report contain the information and methodology on which the results are based. The data as a whole describe a hydrological model for the investigation area. The model suggests that adequate to abundant ground water exists beneath the subdivision and that the proposed development will likely have minimal or no impact on surrounding well users. 1.1 Site Description The physical location of the property is the eastern portion of the undeveloped sections of Denaly Subdivision, also known as Tract Al, in Eagle River. Previously Lots 1-25 of Denaly Subdivision were developed. The tract is located at approximately mile seven of Eagle River Road on the southeast side of Eagle River Road. Figure i shows the location of the property of interest within the Municipality of Anchorage. 2.0 OBJECTIVES Our objectives for this project are as follows: • Evaluate the available well, aquifer and groundwater quantity data. • Identify the number and type of aquifers that lie within the investigation area. P:\2017 Projects121711 - Groundwater Resource Ivestigation Update for Denaly Subdv - Eklutna Inc\Report of Groundwater Evaluation 20171An Evaluation of Groundwater Resources for Denaly Subdivision.doc Page 1 of 12 • Evaluate aquifer conditions and estimate the water production potential of the proposed Denaly Subdivision. • Assess potential impacts of the proposed development to surrounding well users. • Assess potential impacts of surrounding well use to the proposed subdivision. • Recommend whether or not additional investigation is warranted, based on our findings. 3.0 DATA SOURCES 3.1 Aerial Photography TERRASAT examined stereo aerial photographs to gain an understanding of the regional geology. We examined both high-altitude color infrared photos to identify regional geological trends and low-altitude color photos to evaluate local surface features that may influence or control the flow of ground water through the area. 3.2 Geologic/Hydrologic Maps and Relevant Publications We examined the United States Geological Survey's (USGS) Water Resources report entitled "Geology and Ground Water for Land-Use Planning in the Eagle River- Chugiak Area, Alaska" (USGS Water Resources Investigations Open-File Report 74- 57, 1974). This report describes the surficial geology near Denaly subdivision. We examined a previous water evaluation and aquifer test report completed for the local area. The water evaluation, performed by TERRASAT and dated December 1999, is entitled "Ground Water Evaluation: Proposed McIntyre Subdivision." The aquifer test report performed by TERRASAT and dated September 15, 1999 is entitled "McIntyre Subdivision Aquifer Test Evaluation". Figure 3 is a map of the surficial geology of the area. 3.3 Well Logs and On-Site Services Reports TERRASAT identified 194 water well records for wells located within 1/2-mile of the property. Well logs were primarily acquired from the Alaska Department of Natural Resources (ADNR) online Well Log Tracking System (WELTS)database at: https://dnr.alaska.govJwelts/#show-welts-intro-template and the Municipality of Anchorage's On-Site Services Laserfiche Weblink (previously the Water and Wastewater Image Database), which also contained well reports, at: http://onsite.ci.anchorage.ak.us/WebLink/CustomSearch.aspx?SearchName=Searc hOnisteDocuments&cr=1. A small number of well logs were available from the United States Geological Survey. We tabulated the information from these sources and created an extensive database (Appendix A). P:12017 Projccts\21711 -Groundwater Resource lvcstigation Update for Dcnaly Subdv-Eklutna Inc\Report of Groundwater Evaluation 2017Wn Evaluation of Groundwater Resources for Dcnaly Subdivision.doc Page 2 of 12 Information provided by the well logs or listed on the On-site Services reports includes well location, well yield, well depth, aquifer type, static water level, and water quality test results. Often, only some of these parameters were listed. Using a geographical information system (GIS), we plotted the water well locations. In the database, we used the WELTS well ID number where available. When a WELTS number was not available, TERRASAT assigned each well an arbitrary identification number in the 40000 or 50000 range. In cases where two or more wells exist on the same lot, the additional wells were listed if the well logs showed new aquifers or important information not seen in the original well log. This was also the case when a well was extended to deeper depth to gain access to more water. Figure 2 shows the locations of the 194 wells included in the database. Well surface elevation was determined for each of the 194 well in the study and well surface elevation was then used to determine elevations of other parameters such as static water levels (n= 184 of 194), top of aquifer elevation and others. TERRASAT used driller's well test data, for 41 wells with available data to calculate standardized yields, transmissivity, storativity and drawdown of the wells. An example of these worksheets are found in Appendix B. TERRASAT hydrogeologists interpreted the thicknesses and depth of aquifers and bedrock when adequate information was available from wells logs or reports. 4.o DATA INTERPRETATION 4.1 Area Aquifers TERRASAT created a conceptual hydrogeological model to visualize subsurface conditions at and near to Denaly Subdivision. The conceptual model is based on interpretation of well logs, stereo air photo interpretation and published geologic reports. Figures A and B below are conceptual models showing the hydrogeologic conditions present in the study area. Figure A shows a diagrammatic cross section of a river valley and two confined aquifers. Figure B shows a longitudinal cross section of the river valley and illustrates ground water flow. Static water elevations for 184 of the 194 wells used in this investigation are portrayed in Figure 4. Data was unavailable for ten of the study area wells for classification into an area aquifer. This elevation data was statistically divided, based on modal values of the static water elevations, into five categories that represent different aquifers. The five aquifers are named Aquifers 1-5 in Figure 4. The lower unconsolidated aquifer (Aquifer 1 in Figure 4) is shown separately in Figure 5. Wells in the unconsolidated lower aquifer have a lower average elevation to "top of aquifer" at 321.4 feet above mean sea level (AMSL) compared to the other main aquifer that exists south of Eagle River Road, the unconsolidated upper (Aquifer 2 in Figure 4), with an average "top of aquifer" elevation for its wells of 417.8 feet AMSL. In Figure A, below, The unconsolidated lower elevation aquifer, the predominant P:\2017 Projects\2171 I -Groundwater Resource Ivestigation Update for Denaly Subdv-Eklutna Inc\Report of Groundwater Evaluation 20171An Evaluation of Groundwater Resources for Dcnaly Subdivision.doc Page 3 of 12 aquifer in the proposed Denaly Subdivision, as well as in the already developed sections, is seen at a lower elevation that the unconsolidated upper elevation aquifer. Figure 6 shows the elevation of the top of aquifer for wells in the study area. The wells south of Eagle River Road are also predominantly in the unconsolidated lower elevation aquifer or the unconsolidated upper elevation aquifer, with only two wells in Aquifer 3. No wells south of Eagle River Road occur in Aquifers 4 or 5. \ Eagle �' i` River rr ‘,.!;',';• �_ V rIXIM -1.r r 5 Aquifer 2 l{'' +,y "mak r. i ' ,,tri fs '1'r••. `; ,q ,1.'

Unconsolidated aquifers are found in a variety of non-solid material, usually sand and gravel. Materials such as clay or compact silt are too compact to be good water bearing material. In addition to bedrock or unconsolidated aquifers,aquifers can be confined or unconfined.A confined aquifer is a water-bearing formation where groundwater is isolated from atmospheric conditions at the point of discharge. The isolation is a result of an impermeable layer above the aquifer. Water is under pressure in confined(artesian) aquifers and the static water level rises above the top of the aquifer. When a well flows at the ground surface, the appropriate term is artesian and flowing. The layer of material separating the aquifer from the surface pressure is called an aquitard and clay is a common aquitard material found in the Eagle River valley. Figure B above shows how confined aquifers and static water level are related. Finally, confined aquifers can be classified into another group if the pressure is such that the water will flow, not only above the height of the top of the aquifer, but all the way to the land surface where it flows onto the ground if not secured. These are often call artesian wells, but technically should be referred to as "flowing wells". An artesian well is actually any confined aquifer where water rises above the top of the aquifer formation. A shallow unconfined aquifer likely exists within the Denaly Subdivision. This unconfined aquifer is commonly called a water table aquifer. The static water level in an unconfined aquifer is at atmospheric pressure, meaning the water level does not rise above the top of the aquifer. We are unaware of wells within the Denaly Subdivision exploiting the upper, unconfined aquifer. Well types of 18o of 194 wells in the study were identified. Fourteen of the 194 well records did not contain information that allowed a determination of aquifer type. P:\2017 Projccts\21711 -Groundwater Resource Ivestigation Update for Denaly Subdv-Eklutna Inc\Report of Groundwater Evaluation 2017\An Evaluation of Groundwater Resources for Dcnaly Subdivision.doc Pagc 5 of 12 4.2.1 Bedrock Aquifers and Wells A majority of the wells completed in bedrock lie north of Eagle River Road, at higher elevations and in a band roughly parallel to Eagle River. One hundred-one (ioi) of the one hundred ninety-four (194) wells within a 1/2 mile of the subject property are found to obtain their water from bedrock wells. Seventy-six (76) of those are located north of Eagle River Road and twenty-five (25) are located south of Eagle River Road. 4.2.2 Unconsolidated Aquifers and Wells Seventy-nine (79) wells completed in unconsolidated aquifers are found in the study area and most of the wells south of Eagle River Road are unconsolidated. Most of the recharge for wells in these unconsolidated aquifers originates far up the valley. 4.2.3 Flowing Wells Twenty-one (21) of the wells in the study area are classified as "flowing" artesian wells. Two (2) of these are completed in bedrock and nineteen (19) are completed in an unconsolidated aquifer. Twenty (20) of the twenty-one (21) flowing wells are located in the unconsolidated lower elevation aquifer. All of the flowing wells are located south of Eagle River Road. Figure 7 shows the location of the twenty-one flowing wells in the study area. The most common aquifer in the Denaly Subdivision is the lower unconsolidated confined aquifer. This aquifer is under artesian pressure and may have static water levels as much as 18 feet above ground surface. While parts of Anchorage have aquifers that barely produce enough drinking water, this aquifer has an abundance of water under pressure. Therefore, a risk of water flowing around the outside of the well casing exists. The consequences of a flowing well include the potential to produce icing in winter months, basement or crawl space flooding and a waste of groundwater resources. TERRASAT contacted Wayne Westberg, of M-W Drilling, to discuss safe drilling practices within the Denaly Subdivision. M-W Drilling's recommendations include the following procedures: 1. Drill and install 10-inch surface casing to 4o feet. 2. Install 6-inch casing inside the 10-inch and fill the 10 X 6 annulus with bentonite chips or #10 granules to ground level. 3. Pull the 10-inch casing back to 20 feet before advancing the 6-inch casing. 4. Drill and advance the 6-inch casing to total well depth maintaining the bentonite chip grout at ground level by filling the annulus with chips. 5. Leave the 10-inch casing in place until the well is completed. P:\2017 Projccts\21711 -Groundwater Resource Ivestigation Update for Denaly Subdv-Eklutna Inc\Report of Groundwater Evaluation 20171An Evaluation of Groundwater Resources for Dcnaly Subdivision.doc Page 6 of 12 6. Remove the surface casing while maintaining the grout level at the minimum depth of the intended pitless adapter installation. TERRASAT concurs with M-W Drilling's recommendations. We recommend that the Platting Board place a condition on the plat that requires homeowners to follow these recommendations when drilling a well or use a method approved specifically for this subdivision by the Municipality's On-Site Services. 4.3 Area Geology "Geology for Land-Use Planning in the Eagle River-Chugiak Area, Alaska," describes the surficial geology of the Eagle River valley. The local geology consists of alluvial channel deposits in terraces, flood plains and small fan-shaped deposits, glacial lake deposits and younger glacial moraine deposits in the Eagle River valley. Valley walls are composed of colluvium (slope deposits). Fractured, low-grade metamorphic bedrock occurs at higher elevations (Figure 3) and bounds the valley. Denaly Subdivision is constructed on two unconsolidated surficial deposits, glacial moraine deposits and colluvial deposits. The moraine deposits are described as beds of moderately well sorted gravel, sand and silt. The colluvium is composed of reworked glacial till deposits and exhibits a wide range of grain sizes. 4.4 Evaluation of Lower Confined Unconsolidated Aquifer TERRASAT conducted an aquifer test within the Denaly Subdivision during 1999. One well was used as a production well and a second well was used as an observation well. Water was extracted at the rate of 113 gallons per minute continuously for 24 hours. Final drawdown in the observation well too feet away was 0.5 feet. The static water level recovered within minutes. Drawdown within the observation well fit a classical pattern for a confined aquifer that matches a Theis equation. Drawdown within the observation well was used to calculate a transmissivity of 19,328 gallons per feet per day and a coefficient of storativity of 0.00056. Applying the derived transmissivity and coefficient of storativity with the Theis equation shows that the aquifer is capable of producing 1,150 gallons per minute for a 24-hour period. We interpret this aquifer to be a very high yielding aquifer. The Theis equation predicts that typical drawdown from a single-family residence will be 0.02 feet 100 feet from a production well. Since aquifer recovery is very rapid, we estimate that drawdown 100 feet away will likely not occur. The Theis equation was used to evaluate impacts from the entire subdivision. We assumed that 45 houses using 450 gallons per day would have a combined drawdown of o.3 feet 500 feet away, the interface of the bedrock aquifers. This P:\2017 Projects\2171 I -Groundwater Resource Ivcstigation Update for Dcnaly Subdv-Eklutna Inc\Rcport of Groundwater Evaluation 2017'An Evaluation of Groundwater Resources for Dcnaly Subdivision.doc Page 7 of 12 means that the Denaly Subdivision will have an insignificant impact on the surrounding community,likely not even measurable over time. 4.3.1 Data Derived from Driller's Well Tests Thirty-three percent (33%) of the well logs for the unconsolidated lower elevation aquifer had sufficient data to calculate standardized yields, and aquifer parameters. The transmissivity used in the calculations was the same as that determined during the 1999 well pump test of the confined lower unconsolidated aquifer. These results were as follows: • Median Standardized Yield = 31.5 gallons per minute • Transmissivity= 66.7 gallons per day per square foot • Storativity = 0.0000496 • Available Drawdown = 149.84 feet These results show that the average well in the proposed new development, completed in the unconsolidated lower elevation aquifer, will be able to produce at least 32 gallons per minute for 24 hours of pumping before drawdown reaches 150 feet (the average maximum available water). This describes a well with a high yield and the ability to pump water for extended periods before drawdown in the well approaches loo%. A typical residential house uses 450 gallons per day or o.3 gallons per minute. 4.5 Observed Aquifer Conditions and Well Yields Figure A on the previous page is a conceptual illustration of two aquifers, the unconsolidated lower elevation aquifer and the unconsolidated upper elevation aquifer found within Denaly Subdivision area. The unconsolidated lower elevation aquifer is the lower of the two. Most of the wells in the proposed expansion of the Denaly Subdivision are likely to be completed in the unconsolidated lower elevation aquifer with the unconsolidated upper elevation aquifer being the only other likely aquifer that would be encountered during new well installation in the proposed new subdivision area. Figure 8 shows depths of each well, with wells depths ranging between 64 feet to 660 feet deep with an average of 248.1. Wells completed within the previously developed portions of the Denaly Subdivision are relatively similar in depth and are in a range of between 64 and 301 feet deep with an average of 172 feet. The top of aquifer elevation for the unconsolidated lower elevation aquifer exists at an average of 321 feet (72 of 76 wells in aquifer) feet above mean sea level (AMSL) and the average thickness of the aquifer is 16.76 (70 of 76 wells in aquifer). Figure 6 shows the top of aquifer elevations for well in the study area. P:\2017 Projects\21711 -Groundwater Resource Ivestigation Update for Denaly Subdv-Ekluma Inc\Report of Groundwatcr Evaluation 2017\An Evaluation of Groundwater Resources for Dcnaly Subdivision doe Page 8 of 12 TERRASAT evaluated available well yield test results for and standardized those results to account for inconsistencies in the testing and recording methods of the drillers and engineers. We evaluated available well yield data reported in driller well logs for well logs within the search radius. Neither the driller's estimates nor the engineer's estimates of well yield are an accurate measure of actual yield. They are estimates based on a rate water was pumped at the time of well construction and testing, not the ability of the well to produce a maximum amount. Thus, we calculated a standardized yield, assuming that the well pumped continuously for 24 hours. While this is a conservative estimate, the process standardizes well yields from the available data. Figure 10 shows the standardized yield of wells in the study area. We selected well data within the unconsolidated lower elevation aquifer and statistically evaluated the driller's well yield data. Using the Shapiro-Wilk test of Normality on the driller's yield data for wells in each aquifer, we determined that each data set exhibits log normal distribution. Therefore, the median of the yield values best describes each aquifer. The median driller's yield for wells in the unconsolidated lower elevation aquifer is 32 gallons per minute (gpm). This was calculated using 25 of 76 well in the unconsolidated lower elevation aquifer. The other aquifers with sufficient number of wells (30% or more versus total wells) were Aquifers 3, 4 and 5 with median standardized yields of 1.2, 1.5, and 2.6 gallons per minute for aquifers respectively. This illustrated the fact that the unconsolidated lower elevation aquifer is a high yield aquifer compared to the other four. The unconsolidated upper elevation aquifer (Aquifer 2 in Figure 4) had a median yield of 0.85 gpm but was calculated with only 3 of 62 wells (4.84%) and therefore that median value cannot be considered. The average driller yield (not standardized) for the unconsolidated upper elevation aquifer was 8.17 gpm,based on 59 of 62 wells. Standardized well yields for the lower confined unconsolidated aquifer have a median value of 31.5 gallons per minute with an open-ended casing. The screened production test well shows the aquifer is capable of producing 1,150 gallons per minute with continuous pumping for 24 hours. We conclude this aquifer, beneath the Denaly Subdivision, is more than adequate to supply water to this subdivision without significant impacts to surrounding water users. We also conclude that recharge is abundant, receiving waters from the Raven glacier and the Eagle River Valley. Importantly, the unconsolidated lower elevation aquifer has a very high recharge rate as well, meaning that any time that water is not being pumped from a well, it fully recharges in a matter of minutes. Many aquifers in Anchorage take much, much, longer to recharge, particularly bedrock aquifers in general. 4.6 Nitrate Occurrence The Denaly Subdivision proposed new development is located at the lowest elevation compared to surrounding subdivisions. Figure 11 is a map of the surface elevation P:\2017 Projects\21711 -Groundwater Resource Ivestigation Update for Denaly Subdv-Eklutna Inc\Report of Groundwater Evaluation 2017\An Evaluation of Groundwater Resources for Denaly Subdivision.doc Pagc 9 of 12 contour showing this relationship. This prevents nitrates or any other concentrate from migrating to other subdivisions. For the proposed new development, however, this is not a concern. The average nitrate concentration for wells in the already developed portion of Denaly Subdivision (5o tests) is 0.653 mg/l. Surrounding subdivisions with higher nitrate averages are: Hamann (22 tests) with 1.47 mg/L, H &H with 1.40 mg/L and Bob Well (7 tests)with 1.22 mg/L. The remaining area subdivision average nitrate concentrations are: Sandhill (11 tests) 0.11 mg/L, Valley View Estates (33 tests) with 0.49 mg/L , Majestic Valley Estates (63 tests) with 0.75 mg/L, Charlice (0.067), Donald Schroeder (0.29), Groll (0.47), Hulse (o.34), Loye (0.25), McIntyre (0.61) and Magnificent Mt. Slopes (0.09). The highest individual well test in the study area was for Hamann Subdivision Lot 17 with 4.92 mg/L nitrate. The ADEC standard for nitrate levels in drinking water is 10 mg/L. No subdivision or specific well in the study area has nitrate concentration levels that are a concern. Figure 12 shows the average nitrate concentration for the subdivisions in the study area. 5.o RECOMMENDATIONS Based on our current ground water evaluation of Denaly Subdivision and surrounding properties, we recommend drilling wells to approximate depths of 130 to 342 feet above sea level to utilize the unconsolidated lower confined aquifer.These depths will likely produce wells in the proposed new subdivision that exhibit artesian flow. Our professional opinion is that additional aquifer testing is unnecessary in the Denaly Subdivision. Results from the 1999 aquifer test show that adequate groundwater resources exist. Water well logs from residential wells in the Denaly Subdivision support the conclusion that adequate water supplies are available. We recommend the following procedure for new well installation within the proposed new subdivision: 1. Drill and install 10" surface casing to 4o feet. 2. Install 6"casing inside the 10"and fill the 10 x 6 annulus with bentonite chips or #10 granules to ground level. 3. Pull the 10"casing back to 20 feet before advancing the 6 inch casing. 4. Drill and advance the 6"casing to total well depth maintaining the bentonite chip grout at ground level by filling the annulus with chips. 5. Leave the 10"surface casing in place until the well is completed. 6. Remove the surface casing while maintaining the grout level at the minimum depth of the intended pitless adapter installation. P:\2017 Projccts\21711-Groundwater Resource Ivcstigation Update for Denaly Subdv-Eklutna Inc\Report of Groundwater Evaluation 2017\An Evaluation of Groundwater Resources for Denaly Subdivision.doc Page 10 of 12 Alternately, TERRASAT recommends using a method approved specifically for this subdivision by the Municipality's On-site Services. 6.o CONCLUSIONS TERRASAT evaluated the occurrence and sufficiency of groundwater to support the Denaly Subdivision. We also evaluated what impact water wells would have on the new subdivision in on the surrounding neighboring water wells. We found that groundwater is recharged from the upper Eagle River Valley, which is far in excess of what the existing community will use. TERRASAT concludes that recharge is expected to remain abundant for the demands of residential use. We found that recharge for surrounding bedrock aquifers are likely from snowmelt and precipitation at higher elevations within the Eagle River valley, a separate source from the unconsolidated aquifers within the Denaly subdivision. Available water well logs and our statistical analysis shows that the community within a half-mile of the Denaly subdivision exploits groundwater from at least five different aquifers. Recharge for these aquifers are up gradient from the Denali subdivision. Therefore, TERRASAT also concludes that, drinking water quality is expected to remain unaffected by the new land development. Aquifer test data on driller's well logs shows that average well yield is approximately 34 gallons per minute for the existing Denali subdivision. Aquifer testing, completed by TERRASAT in 1999, shows that the confined unconsolidated aquifer is capable of producing 1,150 gallons per minute. Wells in the subdivision are expected to use on average of 0.31 gallons per minute. We predict that the drawdown 100 feet away will be approximately 0.02 feet, an insufficient amount of impact to neighboring lots. The entire subdivision, with each well pumping at 0.31 gallons per minute, is expected to have a drawdown 500 feet away of 0.31 feet. Five hundred feet is the distance to the bedrock aquifer north of the subdivision. Therefore,we conclude that impact to the surrounding community and adjacent lots will be insignificant. TERRASAT evaluated the occurrence of nitrate in aquifers in aquifers that surround Denaly subdivision. We found that, nitrates average anywhere from 0.067 to 1.47 mg/L in the surrounding subdivisions. The maximum nitrate value was 4.9 mg/L. We conclude that, nitrates are not a concern in this portion of the Eagle River Valley. Denaly subdivision, with an average nitrate concentration of 0.653 mg/L, is one of the lowest in the area. We predict that the expansion of the Denali subdivision will have a minimum to no impact on the upper unconsolidated aquifer because it has fairly abundant recharge which would cause dilution. The unconsolidated aquifer underlying Denaly subdivision would also act as a filter for bacteria, encouraging denitrification of nitrates. Please contact us at 344-9370 if you have any questions.

Denaly Estates Subdivision is a proposed 20 lot residential development in Eagle River, Alaska. Access to the development is via Eagle River Road to Denaina Drive, then to McIntyre Road. McIntyre Road currently exists as a gravel road with little to no roadside drainage infrastructure. It is not identified within the adopted Official Streets and Highways Plan (OS&HP) and is considered a secondary (local) street. According to Chapter 1 of the Design Criteria Manual (DCM), "secondary streets usually have lower design volumes, typically less than 2,000 trips per day, and speeds..." McIntyre road currently provides access to 8 parcels of land north of this development, 6 of which contain residential structures. According to ITE Trip Generation Rates (9th Edition), these 6 lots contribute 9.52 trips per dwelling unit for a total of 57 average daily trips. Denaly Estates Subdivision plans to develop 20 residential lots along the existing McIntyre Road and a new proposed unnamed road. Road improvements are anticipated to consist of upgrades to the existing gravel road to strip paved standards with roadside ditches as well as the construction of a new road to provide access to 6 proposed lots. Once developed, the 20 residential lots will contribute 190 average daily trips. Denaly Subdivision, platted in 2000, is an existing 25 lot development located off of Denaina Drive, Bendilent Circle and Kulchay Circle. These existing roads are also considered secondary (local) streets that direct traffic to Denaina Drive and eventually Eagle River Road. This existing development contributes 238 average daily trips. The Denaly Estates Subdivision will contribute 190 average daily trips to an existing traffic loading of 295 daily trips for a total of 485 average daily trips along Denaina Drive. The estimated total traffic loading for the neighborhood, once fully developed, is well below the general limit of 2,000 trips per day for secondary(local) roads as defined in the DCM. In summary, the addition of 190 trips per day from the proposed Denaly Estates Subdivision does not significantly impact neighboring streets and likewise does not alter the current road classification of Denaina Drive.

More specifically, the development is located off of Eagle River Road and generally begins at the intersection of Denaina Drive and Bendilent Circle. The project site resides within the Eagle River watershed and consists of approximately 30 acres of an existing 64 acre tract of land. The current legal description of the property is Denaly Tract Al. Development plans include the installation of infrastructure to develop approximately 20 residential lots, with a minimum lot size of 40,000 square feet. Improvements will include publicly maintained strip paved roads and vegetated drainage swales along with on-site well and septic systems on each lot which will be furnished by the future home owners. o. 5 C'Ystcr 'G,.

Project Location EXCELLENCE IN CIVIL ENGINEERING SINCE 1982•SITE PLANNING• CIVIL ENGINEERING DESIGN• PROJECT MANAGEMENT VJNNV.TRIADAK.COM Current Site Conditions The proposed subdivision is currently undeveloped with access to the site via Denaina Drive. McIntyre Road, an existing gravel road, crosses the property providing access to both this project as well as 8 developed parcels located immediately north of the project site. The remainder of the parcel is undeveloped with native vegetation consisting of shrubs, spruce trees, birch trees and alders. The site generally drains from the northeast to the southwest towards Eagle River. Existing slopes range between 5% and 20%towards Eagle River. See below for the existing drainage pattern of the area. f t f r , Existing Drainage Pattern MOA wetlands mapping indicates Class A and B wetlands present along the southwesterly boundary of the project. This area abuts the Eagle River greenbelt and is anticipated to remain undeveloped. Title 21 requires a 15' non-disturbance setback from all Class A and Class B wetlands not authorized for development. Municipal flood plain mapping of the area indicates that the site does not reside within a floodplain. A geotechnical investigation performed by Northern Geotechnical Engineering, Inc, in May 2006, indicates native soils consisting of sand/gravel mixtures with varying silt content. Future Development Twenty single-family, residential lots are proposed with a minimum size of 40,000 square feet. McIntyre Road is to be improved with strip paved asphalt, roadside ditches and cross culverts to safely convey runoff and continue to allow drainage from the northeast side of the project to reach Eagle EXCELLENCE IN CIVIL ENGINEERING SINCE 1982•SITE PLANNING•CIVIL ENGINEERING DESIGN•PROJECT MANAGEMENT VVVVVV.TRIADAK.COM River. The relatively large lot size proposed for the development is expected to create minimal increases in runoff. Any increase in runoff from the future development will need to be collected and addressed in accordance with Municipal drainage requirements. This generally requires developments to match post development rates to pre development rates thereby reducing if not eliminating any downstream impact. For projects such as this that do not have piped storm drain facilities available, rock infiltration galleries are often used to match post development flows to pre development rates. The percolation tests performed on site indicate that infiltration galleries will need to be carefully designed in order to meet the drainage requirements of the Design Criteria Manual. The final design elements will ensure there are no negative downstream impacts to the existing condition of Eagle River or to adjacent properties. Glaciation concerns are present within this site as is common within hillside developments in the Eagle River area. While generally hard to predict, glaciation tends to occur at locations of shallow subsurface water flow which can vary seasonally. When this shallow flow daylights, it freezes and causes glaciation. To combat this issue, known locations of shallow groundwater flow discovered during the future installation of the roadside ditch improvements will be over excavated and the excavation lined with rock. .The installation of fin or curtain drains is also a viable tool in the event that rock lined galleries are not practical. The goal of the process, whichever method used, is to keep the shallow subsurface water underground and in a thawed state. The Autodesk storm and sanitary analysis 2015 computer program, which utilizes the SCS TR-55 methodology, will be used to analyze and model the project drainage in both the present and future conditions as required by Chapter 2 of the Municipality of Anchorage 2008 Design Criteria Manual (DCM). Summary Based on the initial review of the site and the existing conditions, the municipal drainage requirements appear to be attainable with no adverse impact to adjacent properties or the Eagle River greenbelt.
