Date: November 11,2015 Subject: 254 Great Pond Road—Written Support for Project Planning Board Members: The following written summary is prepared on behalf of the owner/applicant,Thomas and Nicole Friel,in support of constructing a 22' x 23' addition and deck. This lot was created in 2010. All the work is outside of 150 feet to Lake Cochichewick. The following items as outlined in the Watershed Special Permit requirements are listed below(responses to required items are in italic); 1. Encouraging the most appropriate use of land This site is zoned residential and the proposed site development items listed above are appropriate for this parcel. The addition is located over a previously disturbed area. 2. Preventing overcrowding of land The proposed addition is 22'x 23'which is minimal. The proposed addition conforms to zoning requirements. 3. Conserving the value of land and buildings. The proposed site development will enhance surrounding building and land values,while being aesthetically pleasing. 4. Lessening congestion of traffic This project will not increase traffic congestion since this is a single family dwelling with limited trips per day. The number of residents within the household has not changed, therefore the number of vehicle trips will not change with this project. 5. Preventing undue concentration of population This project is consistent with surrounding property uses and as such will not have a measurable impact on population. 6. Providing adequate light and air There will be no adverse impact to current background air and light levels. 7. Reducing the hazards from fire and other danger. There will be no increase in hazard levels from fire or other dangers. The proposed structure will be easily accessible to fire fighting equipment and will meet Building Code requirements in providing smoke detectors. PO Box 2004 Woburn,Massachusetts 01888 (781)854-8644-Phone 8. Assisting in the economical provisions of transportation,water, sewerage, schools,parks, and other public facilities. This project will not impact the above noted public facilities andlor utilities. There will not be a negative impact to the economics of any public utility. 9. Controlling the use of bodies of water,including watercourses: This project will not have a negative impact on present uses of the Lake or tributaries thereto. 10. Reducing the probability of losses resulting from floods: This property is not located within a designated Flood Plain as shown as the latest FIRM maps. The proposed construction will utilize drainage mitigation to collect& recharge stormwater runoff back to the groundwater table. There will be no increase of stormwater runofffrom this site. There will be no increase in flooding probability due to the development of the property. 11. Reserving and increasing the amenities of the Town This project will increase the amenities of the Town through an improvement to the property and additional tax revenue due to the new construction assessment. The Planning Board, in reviewing this application, will note that all threshold requirements for granting the Special Permit are met and/or exceeded. Further written documentation is provided below(responses to required items are in italics) 1. Written certification by a Registered Professional Engineer, or other scientist educated in and possessing extensive experience in the science of hydrology and hydrogeology, stating that there will not be any significant degradation of the quality or quantity or water in or entering Lake Cochichewick. 1) No pesticides,fungicides, chemicals, or non-organic fertilizers will be used in lawn care or maintenance. Presently, there are no limitations on the type or quantity of fertilizers. 2) Siltation controls are proposed at the limit of work during construction and until the site is final stabilized by landscaped means to protect the lake and surroundingproperties from any potential runoff impacts. 3) Stormwater mitigation has been provided to account for all increased impervious areas. Runoff associated with the increased impervious surface (roof area)will be conveyed to a drywell system to promote groundwater recharge. 4) The existing dwelling is connected to the municipal sewer system;therefore there will be no potential increase in nitrogen levels over the existing background levels at the property. 5) This site directly abuts the lake. Natural wooded buffers will be retained within 150 feet of the lake. 6) Careful planning went into the addition to limit site grading changes and to match the existing topography. By limiting the grading changes onsite, existing drainage watercourses will continue to function as in the existing condition. 2. Proof that there is no reasonable alternative location outside the Non-Disturbance and/or Non-Discharge Buffer Zones, whichever is applicable, for any discharge, structure, or activity, associated with the proposed use to occur. Since the existing house is located entirely within the Non-Disturbance zone and the addition is attached there is very little flexibility in locating the addition outside the Non-Disturbance Zone. PO Box 2004 Woburn,Massachusetts 01888 (781)854-86"-Phone 3. Evidence of approval by Mass DEP of any industrial waste water treatment or disposal system or any waste water treatment of system 15,000 GPD capacity. This item does not apply to this site. 4. Evidence that all on-site operations including,but not limited to,construction,water water disposal, fertilizer applications,and septic systems will not create concentrations of Nitrogen in groundwater,greater than the federal limit at the downgradient property boundary. The existing dwelling is connected to the municipal sewer system and the deed restriction only allowing organic or slow-release nitrogen,phosphorus free produce for fertilizer use will insure that background nitrogen levels in the groundwater table will not be increased. 5. Projections of downgradient concentrations of nitrogen,phosphorus,and other relevant chemicals at property boundaries and other locations deemed pertinent by the SPGA. There will be no downgradient concentration of the above referenced chemicals as outlined in the response to Item 4 above. If you should have any questions or require additional information please feel free to contact me. Very Truly Yours, `mod Jack SullivaYi,P.E. ..
