Dear Mr. Martin:
This letter shall request a variance to the Subdivision Ordinance for deletion of lime
stabilization in th· subgrade. The pavement analysis and recommendations of the
Geotechnical Report offers several options to increase the effective modulus pf subgrade
reaction (k) value. The Geotechnical Report was prepared by REED ENGINEERING
GROUP, INC., in April of this year. A copy of the 'Pavement' Section on Pages 11-15
of that report has been provided for your reference and records.
The GeOtechnical Report recommends a minimum five (5) inch section of 3,000-psi
concrete on a six (6) inches of line stabilized subgrade. The Report also allows
increasing the pavement thickness or strength versus stabilization of the subgrade. _The
sections proposed for thisproject are five (51 inch and six (6) inch 4.000-~-~i ~'-~ncret_e
r~i-nfor.c, ed with No. 3 bars on eighteen (18)inches on centerS, - -
Your favorable consideration and approval of this variance for deletion of lime
stabiEzation in' the subgrade is requested. Please advise should you have any questions
concerning this request.
